ER Collet Chuck Enhances Rigidity, Repeatability
BIG Kaiser's ER collet chuck is a standard collet system using the precision tooling company's dual contact spindle system, the BIG-PLUS interface. The BIG-PLUS tool holders enhance rigidity and repeatability for higher metal removal rates, higher accuracy, improved surface finish and longer tool life, according to the company's press release. Fret corrosion is also avoided by the tool holder's ability to keep vibration to a minimum; it reduces cutter deflection, and no axial movement occurs under high-speed operation.
The ER16 and ER32 collet chucks come in BIG-PLUS CAT40 and 50 tapers, and they can supply coolant through either the spindle itself or the spindle flange. The ER16 is available in gauge lengths of 2.5, 4 and 6 inches for 40 taper as well as 3.5, 5 and 6 inch gauge lengths for 50 tapers. The ER32 chuck comes in 3, 4 and 6 inch gauge lengths for 40 taper and 3.5, 5 and 6 inch lengths for 50 tapers.
The ER series chucks come with the tool body and collet nut, and they can accept ER collets or sealed nuts from any manufacturer.
