BIG Kaiser Introduces New ER Collet Chuck, First Industry Standard Collet Chuck With BIG-PLUS Interface

untitled

Elk Grove Village, IL - BIG Kaiser introduces its ER Collet Chuck, the first common industry collet chuck available with the BIG-PLUS interface. A standard collet system can now be used in conjunction with a BIG-PLUS tool holder to achieve the benefits that the dual contact spindle system was intended to provide.

The ER16 and ER32 Collet Chucks are only available in BIG-PLUS CAT40 and 50 tapers and are capable of supplying coolant through the spindle or through the spindle flange. The ER16 collet chuck is available in 2.5, 4, and 6 inch gauge lengths for 40 taper, and 3.5, 5, and 6 inch gauge lengths for 50 tapers. The ER32 chuck is available in 3, 4, and 6 inch gauge lengths for 40 taper and 3.5, 5, and 6 inch gauge lengths for 50 tapers.

The release of the new ER series allows users to take advantage of the BIG-PLUS benefits without having to invest in an entirely new collet system. The new chucks are supplied with the tool body and collet nut only and will accept ER collets or sealed nuts from any manufacturer. For high-precision and high-speed applications, BIG Kaiser still recommends the use of their New Baby Collets due to their superior gripping force and runout accuracy compared to an ER collet.

The simultaneous spindle and flange contact provided by BIG-PLUS tool holders greatly enhances rigidity and repeatability, which yields many benefits in higher metal removal rates, higher accuracy, improved surface finish, and extended tool life. It will also minimize vibration to prevent fretting corrosion; eliminate axial movement during high speed operation; and resist cutter deflection, improving accuracy and finish.
