CNC Mini-Mill User's Guide
Milling Basics
The Mini-Mill's three table motions are classified as X, Y and Z axes, and are standard to
most industrial operations. Additional CNC programming terminology is explained in the CNC
User's Guide. If you are not familiar with CNC program and controls, it is recommended that
you study this prior to using the Mini-Mill system.
Types of Work
There are three basic types of work the Mini-Mill can perform; milling, drilling, and boring.
Additional work with accessory items such as our Mini-Rotary Table is available for attaining
machining of cylindrical objects.
Milling on the CNC Mini-Mill is usually accomplished with end-mills. These are the cutters
designed to cut with both the sides and the end.
Drilling is accomplished by special CNC commands given to the mill. It is also recommended
that center drills be used prior to drilling to achieve the maximum degree of accuracy.
Spindle Mechanism
It is important to note that you can overload the spindle motor. The many variables involved in
machining, such as materials being machined, size and shape of end mill, sharpness, can
lead only to one rule to follow .... Common Sense!
Heavy cuts at low RPM will make the motor run hotter than light cuts at high RPMs. In normal
operations the spindle motor will run warm to the touch, but not hot. This does not mean your
machine can not run at low RPMs, but only that the load put on the motor must be considered
in each setup and operation of the machine.
Cutting Tools and Standard Accessories
End Mills
End mills are the standard vertical mill cutting tools. Your Mini-Mill was designed to employ
miniature series end mills, having 1/8", 3/16", or 1/4" shank sizes. A 3/8" end mill holder is
also available. We recommend using 2-flute, single-end, high speed steel end mills. The solid
carbide tools are more expensive,
and the cutting edges will chip unless used properly. End mills may be purchased from
industrial machine shop outlets or catalogs. As smaller diameter cutters (less than 1/8") are
