Multimachine Bid

Introduction

This machine is a highly-replicable, low-cost, CNC Multimachine for general purpose precision machining of all types, including making of gears and inner splines/keyways, and including a surface grinder attachment for making precision metal from stock. Intended purpose is making items including hydraulic motors, steam engines, electrical generators, couplers of all sorts, and precision motion systems. It can also be retrofitted in later versions with other tool heads for overkill operations including router, 3D printer, circuit mill, and torch. for
