All collets and guide bushings are offered in standard and ultra-precision grades. Round, square, hexagon, rectangular and custom profiles are available.
A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
An aerospace machine shop meets a special need by using a vacuum chuck.
Don't assume the standard chuck is the right workholding for every lathe application.
