Please don’t skip this section as it would help you in making buying decisions in the best possible way.
Especially the ones who are buying the mini milling machine for the very first time would be benefited most.
Speed and Power
Speed and power play a crucial role when it comes to buying a benchtop milling machine, mini milling machine, etc.
For example, if you’re planning to mill a hardened metal or stainless steel then definitely you need a powerful machine like the ones that I’ve recommended in the top slot.
If your projects involve milling steel then let me tell you it’s not an easy task at all.
Make sure that you get a machine that generates enough power in order to mill hardened materials.
Give preference to the mini milling machine that comes with a very powerful motor as well as adjustable speed.
For materials such as aluminum, brass, composites, and wood, almost all the milling machines that we’ve reviewed are capable enough to do them justice.
On the other hand, if your primary objective is to look for a machine that is perfect for model making then definitely you don’t have to worry about the power too much as your interaction and involvement would be mostly with smaller materials.
Moving further, let’s have a quick look at the horsepower that is crucial from the buying point of view.
Well, for a benchtop milling machine that is mainly used for miniature work or malleable materials, a horsepower of 1/8 would be sufficient.
For mild to intense jobs, you can opt for a machine that has an HP of 1.
Similarly, for specific and complex jobs, you can opt for 2 HP.
Definitely, power is very important, but at the same time, you can’t negate the importance of speed, right?
As we all know, for milling different materials, you need different rates, so you should always prefer a machine that has a good number of speeds because it would add to the flexibility for sure.
Each machine comes with a minimum and a maximum RPM.
A high-quality branded machine will give you an option of eight different speed settings to choose from.
There are many milling machine models that offer variable speeds to choose from that means you can choose any speed between the prescribed RPM range.
I always recommend the milling machines that come with a variable speed because it really helps you in fine-tuning the speed in the best possible manner.
Accuracy and Vibration
If you would’ve used a benchtop milling machine or any other power tool then definitely, you would be aware of the fact that the things that affect accuracy more than anything else are stability, isn’t it?
So, to prevent vibration, the tool should have a very rigid, robust, and strong base such as cast iron.
Not only the cast iron base is capable of handling the force of milling but also it is meant to absorb some of the vibrations.
Needless to say, cast iron has a longer lifespan and would last for years to come.
But, cast iron alone wouldn’t be sufficient for the accuracy.
In fact, the worktable also contributes to accuracy.
Mostly, the worktables are made of metal usually steel or aluminum depending upon the quality of the table.
The good thing about the milling machine table is that it comprises of T-Slots that you can use to attach clamps to hold down your material while you work.
Capacity and Size
Definitely, capacity and size would be important parameters for you especially if you’re a professional and looking for a milling machine that could fit well in your workshop.
Depending on your requirement, you can choose from large and small milling machines.
But, make sure that you’ve enough space in your workplace after you’ve installed the machine in order to carry out the milling process without any hassle.
Another important parameter is spindle distance.
Well, many of you, wouldn’t be aware of the fact that the spindle goes up and down with the spindle distance measured at the highest point.
Similarly, you can’t ignore the importance of the worktable, right?
Don’t ignore the travel distance, right?
The worktable moves side to side, and front to back and the distance that they travel tells you about the total working area.
Trust me, it matters a lot because the further the table moves, the less you’ll have to reposition your work as you go.
It goes without saying that working on complex projects may have a requirement of making complex angles, right?
If that is the case, then I would recommend you should look for a milling machine with a head that is capable of tilting and rotating.
Some heads are capable of tilting full 360 degrees while the rest can tilt up to 45 degrees from left to right.
Milling Machine Vs. Lathe Machine
To be honest, the main difference between a lathe machine and a milling machine is the relationship between the workpiece and the tool.
In a lathe machine, the workpiece that you want to machine spins about its axis of the lathe machine, while the cutting tool doesn’t.
This process is termed “turning” and is highly effective for creating cylindrical parts.
Some of the common operations done on a lathe machine are drilling, boring, threading, parting, and even ID and OD grooving.
Moreover, if your project demands the creation of quick, repeatable, and symmetrical cylindrical parts. then definitely, the lathe would be the best choice.
On the contrary, the tool rotates in a milling machine about its axis while the workpiece doesn’t
The good thing about this mechanism is that it allows the tool to approach the workpiece in many different orientations that are really helpful in complex projects.
It goes without saying that the main reason to use a milling machine is its versatility. In fact, the tooling options are numerous in the case of a milling machine.
Needless to say, a mill is capable of putting in more complex pieces than a lathe.
Milling Machine Vs. Drill Press
Have you ever operated a drill press?
Let’s have a quick look at some of the key differences between the two.
Axes Of Motion
A drill press can only perform vertical motion so it can’t drill along the faces of a workpiece.
On the other hand, a milling machine can easily cut along the faces of a workpiece.
In fact, you can use a milling machine in making faces of material flat, and the phenomenon is termed “facing-off”.
Unlike the drill press, a milling machine is capable of cutting slots in material and also, to a specific overall dimension.
Size and Accuracy
Drill presses come in various sizes. Some are small and compact while others are bulky and bigger.
On the other hand, almost all the milling machine models are typically bulky as there is no scope for a smaller version, indeed.
In the context of accuracy, the milling machine wins with a tangible margin, indeed.
All the credit goes to the movement of the work table in the milling machine.
Since you can move the table in both x and y directions so you can definitely line up the material in a better way as compared to a drill press.
In the case of a drill press, you need to use your hand to place the material, then you’ve to tighten it down to the table, thus, giving a lot of room for error, isn’t it?
The milling machines are definitely more expensive as compared to drill presses.
A typical benchtop drill press would cost you around a hundred dollars.
On the other hand, a milling machine would cost you a few thousand dollars.
In short, you need to pay extra bucks for getting more accuracy and other additional features.
Benchtop Milling Machine Safety Measures for Beginners
As we all know, power tools come with certain risks associated with them.
So, I also suggest the newbies be a bit more careful in order to prevent any unwanted incident that may occur because of not operating the machine in the correct way or not taking proper precautions.
Allow me to discuss quite a few of them.
- Adding stability to a benchtop milling machine isn’t difficult or time-consuming. All you need to do is to bolt the machine down. In case, you’re operating the machine without bolting it then it may impact your accuracy drastically as chances are high that during the operation the benchtop milling machine will move slightly
- Moreover, it is highly recommended that you should wear both mask and gloves while operating a mini milling machine as they will protect your eyes and nose against the small metal particles flying in the air
- Never ignore the maximum load rating. In layman’s language, the more load a machine can handle the better it’s probably built
What is a milling machine?
Well, a milling machine is an important power tool similar to a lathe and drilling machine.
The machine comprises a multi-point cutter that rotates against the workpiece in order to remove materials from it.
As the name suggests, a milling machine is used for milling metal.
So, what is milling?
Milling is a process of removing metal by feeding the workpiece with the rotating multipoint cutter.
Most milling machines are capable of holding one or more cutters at a time, and as per your requirement, you can change the speed.
At a higher speed, the material from the workpiece is removed at a faster pace.
Milling Machine Parts
Let’s have a quick look at the different parts of a milling machine and their functions.
As the name suggests, the base is the foundation part of a milling machine and is mostly made of cast iron in order to provide stability and durability.
All the parts are attached to the base and it carries the entire load so it must possess high compressive strength.
A column is mounted vertically on the base.
Not only it supports the knee, table, etc, but also works as housing for all other driving members.
If you don’t know about the column then let me tell you it’s a hollow member which contains driving gears.
Moreover, columns of some mini milling machine models also contain motors for the spindle and table.
The knee is the structure that is used for supporting both the saddle and the table.
You might not be aware of the fact that all the gearing mechanism is enclosed within the knee.
An elevating screw is used to not only support but also adjust the knee.
What actually the elevating screw does is adjust the knee up and down by either raising or lowering the lever.
The lever can be raised or lowered with the help of either hand or a power feed.
A saddle works as an intermediate part between the table and the knee.
Its main function is to provide motion to the workpiece in a horizontal direction.
Mostly, the saddle is made of cast iron.
The rectangular casting that is present on the top of the saddle is nothing but the table.
Moreover, you can think of it as a part of the milling machine that is responsible for holding the workpiece while milling.
You can vertically move it by simply moving the knee up and down.
Similarly, you can move it horizontally with the help of the feed screw.
You can fasten arbor support with the help of an overarm.
Mostly, the overhanging arm comprises one or two cylindrical bars that slide through the holes in the column.
It is also made of cast iron.
One of the important parts of the milling machine is the spindle as it is used to hold the tool in the right place.
The main function of a spindle is to provide the drive for arbors, cutters, and attachments.
In a horizontal mill machine, an arbor is used as an extension for the spindle.
You can fit it on the spindle as per your requirements.
It also helps in not only holding the tool but also moving it in the right direction.
Most of you must be aware of the fact that there are mainly two types of arbor support used in the mill machine.
The first one has a small diameter bearing hole, 1-inch in maximum diameter.
On the other hand, the other one has a larger diameter bearing hole, usually up to 23/4 inches.
The thing that I liked about the arbor support is that it comprises an oil reservoir that lubricated the bearing surface.
Moreover, the arbor support can be clamped anywhere on the overarm.
However, you must remember that arbor support can only be used in horizontal types of milling machines.
The milling head is the topmost part of the vertical milling machine.
Mainly, it comprises a spindle, driving motor, and other controlling mechanisms.
Well, one end of the ram is attached to the column, and the other end to the milling head.
You can use a hand lever for moving the ram in and out.
Types of Milling Machines
In this section, we would be discussing the types of milling machines in order to help you make an informed buying decision.
Column and Knee Type Milling
This is one of the most common types of milling machines.
In this machine, a vertical column is attached to the bed which consists of all the gear drives that are responsible for rotating the knee and the saddle.
To provide vertical motion to the workpiece the knee is situated on the base.
On the other hand, a saddle is attached to the upper section of the knee which can move in a transverse direction.
You can use climbing bolts to hold the workpiece on the table.
Vertical Milling Machine
As the name suggests, the spindle of this machine is in a vertical position.
You don’t require any arbor for a vertical milling machine.
Moreover, the cutter tool has a cylindrical shape, and the cutting edges are situated at the circumference of the cylindrical face.
Horizontal Milling Machine
On contrary to a vertical milling machine, here the spindle is situated horizontally.
So, the spindle movement is in the horizontal direction.
In the horizontal milling machine, an arbor is attached to the machine that holds the cylindrical disk shape cutter which is responsible for cutting the workpiece.
Universal Milling Machine
Well, a universal milling machine resembles a horizontal milling machine to a great extent.
The major difference between the two lies in the fact that the universal milling machine has an arrangement of swing up the table of 45 degrees in either direction.
Fixed Bed Milling Machine
As the name suggests, fixed bed milling machines are the ones in which the bed is fixed to the machine.
You’ll not find any arrangement to move the machine in either a vertical or horizontal direction.
Moreover, the worktable is directly situated on a fixed bed.
If we talk about the spindle then it is mounted on a movable spindle head.
Simplex Milling Machine
Simplex milling machines are the ones in which spindles travel in only one direction.
In most case, the spindle travels in the vertical direction.
Duplex Milling Machine
In a duplex milling machine, the spindle travels in both horizontal and vertical directions.
Triplex Milling Machine
These are the machines in which the machine can move in all three directions, that is, along the X, Y, and Z-axis.
Planner Milling Machine
A planer milling machine resembles the bed-type milling machine except it can be mounted with various cutters and spindle heads to the machine.
These machines are mainly used for facing operations in mass production.
Special Milling Machine
These are one of the most modern milling machines that are developed in order to make the entire milling process easy and less time-consuming as per the requirement of the job.
Tracer Milling Machine
The tracer milling machines are the ones that are mostly used in the automobile and aerospace industries.
It can develop any difficult shape and can perform most of the most difficult tasks.
CNC Milling Machine
The good thing about the CNC is that it is one of the most versatile milling machines and is controlled by a computer.
In simple words, you can think of it as an upgraded version of the bed-type milling machine in which the spindle can move in all three directions, and also, the table can rotate 360 degrees.
All these movements are hydraulically controlled which is commanded by a computer.
A sketch of the workpiece is loaded to the computer and the same is cut on the workpiece by the cutters automatically.
Types of Milling Machine Operations
Well, let’s have a quick look at various types of operations that a milling machine can perform.
It will help you to understand the potential as well as the capabilities of a milling machine.
Plain Milling Operation
The plain milling operation is popularly known as slab milling and is mainly performed to produce a plain, flat, horizontal surface parallel to the axis of rotation.
Most of the jobs need such operations, and the best part is that it can be expedited on almost every milling machine.
Face Milling Operation
Well, face milling operations can be performed on surfaces that are perpendicular to the axis of the cutter.
Moreover, the operation is performed by the face milling cutter mounted on the stub arbor of the machine.
End Milling Operation
In the end milling operation, flat surfaces are produced that can be horizontal, vertical, or at any angle with reference to the worktable.
Form Milling Operation
This is an idiosyncratic sort of operation that you can accomplish with the help of convex, concave, and corner rounding milling cutters.
In this process, the special contour is machined that is composed of curves, straight lines, etc at a single cut.
T-Slot Milling Operation
The T-Slot milling operation is a process of producing the T-Slots on the workpiece with the help of a T-Slots milling cutter.
Side Milling Operation
Well, the side milling operation involves the side milling cutter for producing vertical surfaces on the sides of the workpiece.
The side milling cutter has teeth on both sides as well as the face.
Gear Cutting Operation
In this operation, gear teeth are produced on the gear blank with the help of a form relieved cutter.
For optimum results, the cutter profile should match the tooth space of the gear.
Straddle Milling Operation
The operation involves producing a flat vertical surface on both sides of the workpiece.
For this operation, the two-side milling cutter is used.
A spacing collar is used to adjust the distance between the two cutters.
The straddle milling operation is mainly used to produce a hexagonal or square surface.
Grooves Milling Operation
The process involves the use of a saw-milling cutter or an end-milling cutter for producing grooves on the surface of the workpiece.
Gang Milling Operation
The process involves the use of two or more milling cutters to perform different milling operations simultaneously.
Well, in the gang milling, the cutters are mounted on the arbor.
Milling Machine Advantages
Let’s discuss the various advantages of owning a milling machine.
- A perfect machine for not only producing individual pieces but also small batches
- Moreover, the milling machines are capable of producing complex shapes with the help of multitooth in an epigrammatic span of time
- The use of general-purpose equipment and cutter reduces the operation cost drastically
Milling Machine Disadvantages
- A bit expensive as compared to casting, cold forming, extrusion, etc
- For mass production, it becomes necessary for you to use special-purpose machines
Milling Machine Applications
- They can be used for making gears
- Can be used for producing both flat and irregular surfaces
- Used to produce groove or slot
- Can also be for the purpose of designing metals and other materials
- Modern milling machines are capable of cutting superalloys, titanium, and tensile steel with not only accuracy but also faster

What is the difference between turning and milling?
Turning and milling are two of the most common machining processes that are used to remove material from a workpiece.
However, they use different methods altogether to achieve this goal.
Turning forces the workpiece to rotate.
On the other hand, milling forces the cutting tool to rotate.
What is the difference between up-milling and down-milling?
|The cutter rotates against the direction of the feed table
|The cutter rotates along the direction of the feed table
|No backlash eliminator is required
|Backlash eliminator is required
|If the workpiece is brittle, up milling is preferred
|Not a good choice for a brittle workpiece
|Burr is formed only on the unfinished surface ahead of the tool feed
|Burr is formed at the finished surface on the opposite side of the tool feed
|At the beginning of the engagement, teeth rub with lay or feed marks on the machined surface. This improves the surface finish
|No such rubbing action takes place, and thus lay marks remain intact on the machined surface
It’s A Wrap
