Best Mini Mill Buying Guide

If you are the type of person that like experimenting and discovering things, you may be in need of a milling machine. If you are very particular with metal parts, then this device should be included in your options.

However, it is challenging to determine where to start. You might ask yourself what kind of milling machine is the best for your needs. Should you buy a brand new one or settle for a used unit?  This buying guide will help in answering most of your common questions.

Kinds of Mill Machine

There are many mini milling machines in the market that you can find, but you need to decide what configuration is best for your workshop. There are manual, and CNC machines and they are different when it comes to drilling power.

You can divide modern milling machines into two types: the horizontal mill and the vertical mill. This will tell you if the spindle axis of your computer will run side to side or up and down. Both kinds include head, tables, swivel, and columns.

One of the ways that you can differentiate these types of machines is through their orientation which can either be vertical or horizontal. A vertical mill machine has a table mounted perpendicularly to the spindle.

On the other hand, the horizontal mill machine has a table paralleled to the table’s plane. This difference tells you the kinds of job are recommended and practical for the two types of mills.

Horizontal Mill Machine

This kind of mill machine’s main strength can be found in the arm. It can constrain the rotation of the arbor. This can provide rigidity and allows you to make heavy cuts that can provide more side loads.

It is possible to stack some cutters to the arbor so you can accomplish clean cuts. A perfect example is a flat table that has slots for all single passes. This is best for surfacing jobs and other cutting grooves.

It can be cumbersome and sometimes impossible to acquire cuts in all the axes. For jobs like this, the vertical mill machine is recommended.

Choosing Your Milling Machine

1) Buying a Brand Name – When buying any kind of equipment, this is one of the hardest questions to answer. This is similar to buying mill machines. The question is, does it matter? There is no definite answer since these machines have been around for so many years.

There are no questions when it comes to their construction. It is also known by many the factors that will make a real mill machine. Manufacturers of these industrial machines can either follow the standard design principles or fail.

They need to consider quality and cost of building these machines. Some manufacturers need to cut corners to keep up with the cost. Poor quality materials would be their resort as well as underpowered motors.

It is recommended to buy a mill machine that has already proven itself in the industry. This means that you need to go with a reputable and respected brand. You wouldn’t like to work with a machine that will only give you frustrations.

2) Size of the Milling Machine – Mini milling machines are portable, but you need to consider first the workshop or project that you are planning to execute. If you are thinking of milling metal, it is best to go with heavy duty machines.

Think of the situation when you need to make a hole in steel. It is surely a difficult task, and you need to exert the tremendous amount of force. Your chose milling machine should be able to release that kind of energy without wobbling and faltering.

You should note that your frame should be heavier and rigid to withstand the hardness of steel. A small mill machine would not be able to withstand anything that is harder than aluminum. The best solution to this is to make use of a heavy-duty mill that is thick and rigid.

3) Power Feed – The digital readout is a kind of module that is added to the axis of a mill machine. However, you must note that not all machines have them. You can avail a package that has been upgraded with this inclusion.

This DRO functions by showing you how far you’ve moved the quill as you go. Apparently, it will make the task easier for you. It isn’t necessary, but DRO can give you a heads up in the steady movement of your mill.

It is troublesome and time-wasting if you read it manually. This is the reason why most professionals opt to buy mill machines that already have a digital readout. Aside from this, it will also be easier to cope with the slops in screws using a DRO.

On the other hand, the power feed can be added to the axis based on your preference. If you want, you can toggle a motor with it. This can help in minimizing fatigue on your part. You’ll come up with a smoother and better surface finish.

4) Spindle Motor – Mechanics value horsepower on machines. If you want to avoid having a stalled motor while you are milling, then choose a factory machine that has the higher power. All mills have a method of gearing down the motor. This is its way of gaining more torque. These devices need higher torque and lower speed.

It is recommended to avail a mill with a horsepower not lower than 1HP. In this case, it is better that it’s not a 3-phase type.

What is 3-Phase Power?

Maybe you have heard about multi-phase power. If you currently have an industrial space, then you probably have a 3-phase power in your home. You should note that all heavy-duty mills have 3-phase motors, and they can’t run on standard single-power.

Mini-mills are ideal for home use because they only require single phase power to run. They are perfect for DIY and other small workshops.

Conclusion

The fun starts when you start milling. However, try to do a little research about these mini-mills. It’s good to compare their power feeds and configuration before you decide.
