Sieg CNC Lathe

The Sieg KC6S is a high quality machine built around precision-ground iron castings. In use, the machine is virtually vibration free. The machine has sufficient power for sensible machining times in an educational setting. A robust, interlocked, case means coolant and swarf are contained and moving parts are guarded.


Our Sieg CNC Lathe package provides a software extension for TechSoft Design V3 that makes designing suitable components very straightforward. Profile lines in the drawing are colour coded according to the operation required. Up to six operations can be selected including roughing, parting-off, threading, etc., each operation being assigned one of the tools in the automatic 4-position toolpost. On ‘CNC Output’ a file is created that contains all the necessary G&M code data for geometry, tool type, feeds and speeds, etc. The file is then opened in the Sieg CNC Turning software and a full G-code listing is displayed. This can be edited if required or specialist users could even programme from scratch here. As a minimum, the Sieg software is used to manually control the machine and to set up tools, apply off-sets and to establish machine datums.


Designing parts and outputting to a CNC lathe can be tricky. TechSoft Design V3 and the Sieg KC6S make the job crystal clear at all stages.
