| Abstract |
Modern lathes such as N.C. machines can only be utilised to the full with chucks that hold the workpiece firmly and the jaws of which are not ejected at high speed. Measures taken in design are described: chucking the work by rack-type jaws or jaws retained by the chuck shell; retaining devices for interchangeable jaws in chucks with several gripping ranges; non-return valves to maintain the grip in the event of failure of the pneumatic or hydraulic circuit; sensors monitoring the jaw plunger position. Lathe controls should be electrically interlocked so long as the work is not fully chucked. Advice is given for preventive maintenance, and design of chucks for very high speeds are presented, together with technical limitations. |
