In the original motor location of the above 2 speed mini milling machines. No instructions yet, just my text number. Eliminates noisy and failure prone internal plastic H/L speed gear.

Servo motor with computer driver eliminates the need for high/low gears. Toothed belt eliminates belt noise and slipping. Rotary speed control is attached to the side of the mill with 2 sided tape included.

Control unit must be attached under a nearby cabinet or other support as seen in images. This places it out of the way and clear of metal filings. There is no spindle locking system for loosening the R8 draw bar. I use the chuck key and a 3/4 chuck. It is fully alpha tested.

You are beta testing it at your own risk. My test results using 2" aluminum 6061 and a 2" fly cutter: Running the fly cutter at 3,000 rpm produced a much smoother finish.

This mod allows the operator to reach rpm's nearly double that of the manufacturers original design. You are responsible for the safe operation of this equipment, If you spin a cutter so fast that a piece breaks off and travels the speed of a bullet, that is your responsibility the same as shooting a gun at the range.

Reverse is simple, just hold the yellow button for a few seconds. Light brightness is adjustable at control unit. Includes the ability to set bottom and top RPM range separately. In other words you can program the system to run the spindle at any speed or range of speeds you choose (see below).

Motor 100 RPM (Spindle 80 RPM). Highest speed this one produced: Motor 4200 RPM. RPM: 100 to 4,500 RPM in 100 RPM increments. This listing is for a fully alpha tested system. A new 750 watt motor like the one seen here in photos.

Motor will come with the motor mount + belt drive installed. Its a little tricky to install on the mill and you will need long metric allen wrenches.

Do not do this because the rest of the mini mill is not built strong/stable enough for this kind of abuse. If you jam it, you may damage the milling machine to include broken cutters, parts and the control unit. All milling machines are dangerous, increasing the. To insure fit and proper application.
