EXPANDING MANDRELS AND COLLET CHUCKS

Expanding mandrels are the ideal solution to many workholding problems. By holding parts on most of the datum bore (or outside diameter in the case of a collet chuck) the clamping forces are evenly distributed, reducing distortions during part manufacture.

Mandrels also provide a superior method of holding parts which are high volume, have short cycle times or require the highest levels of concentricity.

Chevin manufacture expanding mandrels tailored to your exact specifications. Many different mounting styles are available, including: spindle nose, between centers, Morse taper and faceplate. Different actuation methods can be used, such as drawbar, cantilever nut and front nut.

Every expanding mandrel or collet chuck supplied by Chevin can have the following features:

• Single taper sleeves
• Positive clamping and release
• High levels of concentricity – to 0.0002" T.I.R
• Controlled datums
• Sleeve interchangeability
• Generous expansion capacities

All of the above permit quick and secure clamping creating versatility and ease of use.
