CONVERSION PLANS

Include detail and assembly drawings, photographs and instructions.  Also source suggestions for bearings, hardware, materials and electronics hardware and software.

All required machined parts can be machined right on the manual mill prior to it's conversion to CNC.
A well designed conversion plan that will guide you through automating a Sieg Industrial built Mini-Mill.  This is a solid iron milling machine.  A perfect machine for engineering prototype work or home shop hobby machinist.
Advantages of using my plans:
1. A machine modified according to these plans will have complete 3 axis CNC capability while retaining full use of all 3 axis manual function.
2. Z axis lead screw is located out of the way of the milling work area above the mill head away from chips and dirt.
3. Plenty of room around the stepper motors allow use of nema 23 or the larger nema 34 frame steppers.
4. No major disassembly of mill is required during the addition of the CNC hardware which makes the conversion quick and easy.
5. The only permanent change to the Mini-Mill required for the conversion is the addition of two tapped holes added to the mill head.
6. All machined parts can be made right on your Mini-Mill prior to its conversion to CNC.
7. Cost of required aluminum stock, lead screw and other hardware will be between $190 and $350 depending on the type of lead screw and motor size selected by the builder.
