This milling machine has a Drilling & End Mill Capacity of 3/8 inches along with a Face Mill Capacity of 5/8 inches.
We feel like many machinists will like the simplicity of this machine. It is easy to use, maintain, and drill with. It may, however, take a little bit of time to trim.
However, even the best industrial machines will require a little work to make them more accurate when they are brand new. If you purchase this machine, you will need to bolt it down it.
This is because is a little bit top heavy. We don’t particularly understand why it comes with end mills but no tool holder for them, as this would make it easier to use.
Keep in mind that you should never put end mills in a drill chuck because this makes it possible to bend a jaw when you are milling.
Also, keep in mind that this machine is fairly light duty in design; it will cut soft steel, but you will have to take your time. We recommend using carbide end mills with this machine because it likes RPM and has little torque to it.
This is a great little hobby mill that would possibly work for industrial applications but is much better for light duty jobs.
We would definitely recommend this for hobbyists though we aren’t sure it’s ideal for some heavy-duty jobs. All around a pretty nice hobby mill at a good price.

This is ideal for adding versatility to any job. The worktable length and width are 3 5/8 inches x 15 3/8 inches. It may need some adjustment to fit your workbench setup.
The steel quality of this machine is very good, though you will need to have decent quality tooling.
Obviously, because of its size, it tends to go slowly when being used on steel.
You may also wish to purchase a recirculating cooling pump with a small fountain pump or a catch pan with a filter around the pump intake.
This will make using this machine easier.
For the money, this is a great unit. It can be a good tool for holes, lines, and fine detailing.
This is one of the most inexpensive mini milling machines out there that’s still of decent quality design and construction.
Keep in mind that this unit doesn’t come with many extras.
It also isn’t premium quality, it’s more of a mid-range option. Still, for any home or hoppy application, this is a great choice for many people that comes at a great price.

If you purchase this machine looking for an advanced Dremel, you will likely be extremely satisfied.
The Proxxon MF-70 performs many useful operations that would be difficult or downright impossible to accomplish holding a Dremel in your hand.
However, if you’re looking for a mini Bridgeport, you might find that you aren’t all that happy. The Proxxon Micro Mill MF 70 is a small and beautiful machine that can be utilized in many ways.
This unit is ideal for precise milling applications.
It is a very accurate mill that would be great for use in a lab, by an optician, a jewelry refiner, or even for electronic and model building projects.
This milling machine is made with a very sturdy cast iron base that helps it stay in place without too much vibration.
Additionally, its vertical column and compound lathe have been treated and are constructed of high-quality aluminum. All of its axes are play-free and also have adjustable slides.
Its headstock has been made of die-cast aluminum and houses a 24 pole balanced special motor. It provides best in class stability, even at its highest operating speeds.
This creates the kind of stability and precision that facilitates the use of even the finest cutters.
The Proxxon 37110 Micro Mill MF 70 also comes with 6 triple slit hardened steel collets. The specifications are 1/32 inch, 1/16 inch, 5/64 inch, 3/32 inch, 7/64 inch, and 1/8 inch.
Its table has three T-slots as well as an adjustable ruler scale for quick and easy measurements.
This is great for adjusting the positioning of your work-piece.
All of its hand wheels are zero adjustable.
This means that one revolution equals 3/64 inch (1.0mm) and that one division equals .002 of an inch (0.05mm). Keep in mind that when cranking the X-axis, the table deflects +/- 0.010″.
`That means that you’ll get 20 thousandths total in error.
If you use a twisting grip on the wheel instead of cranking the handle, it will help to reduce this to only a few thousandths of an inch.
Tightening the Gibbs also helps, however, the motion then becomes a bit “sticky”.
The Z-axis scale ring also tends to hang up sometimes which may throw it off zero and cause certain errors. Additionally, the head doesn’t rotate which can be frustrating for anyone who wants to position the spindle horizontally.
However, if you need to create precision work and can’t accomplish that with a Dremel, this machine is a great option to consider.

To understand how micro milling precision works, you may want to take a look at this in-depth article .
Vertical VS Horizontal milling?
With all of the power and precision offered by micro-milling machines, it’s hard to find a machine that can handle every single job.
Understanding the difference between vertical and horizontal milling can help you choose which machine will best fit your individual needs.
Vertical milling machines have a cutting head called a spindle. This spindle is oriented vertically and can be controlled in many different ways.
It can be raised or lowered and is combined with a bed that can be moved in a horizontal way. The combination of these movements allows the operator to create different shapes at different depths.
A turret mill has a spindle and is usually in a position that is fixed. The bed can be moved vertically and horizontally which brings the material being milled to the cutting surface. These mills are great for smaller pieces.
Horizontal milling machines make use of a horizontal arbor to mount on to cutting surfaces. The cutters on a horizontal mill are similar to the blade of a circular saw.
They have a size and shape that is ideal for generically cutting faster than a spindle or vertical mill can. Multiple cutters may be installed on a mill of this kind because of the extended length of the arbor across the width of the bed.
Both vertical and horizontal micro-milling machines have benefits and can be used with CNC technology.
There are also various add-on parts available for each type of mill to help make any job easier.
The mill that you choose will depend most heavily on the uses you intend it for and the applications that it will need to serve.

Mini milling machine vs Lathe machine?
Deciding if you need a milling machine or lathe machine is important. Both milling machines and lathe machines follow the same basic principles of operation.
This principle is known as subtractive machining.
Subtractive machining begins with a block of material and then shapes the material based on the specifications of the machinist.
The big difference between mini milling machines and lathes comes in when the material is shaped. These machines create different shapes and depths in materials and there is a large difference in the relationship of the workpiece to the tool.
For more on how these machines differ, it may be helpful to read this article..
