CoroChuck 930 from Sandvik Coromant now suits BIG PLUS spindles
Demand from BIG PLUS users for secure tooling performance in milling and drilling operations has led to the additional availability of the CoroChuck 930 hydraulic chuck from Sandvik Coromant for this patented spindle system.
Suitable for meeting demands for high run-out precision (<4 micron at 2.5 × DC), extensive tests have shown that CoroChuck 930 provides the best pull-out resistance available on the market, says Sandvik Coromant. The secret can be found in the design of the brazed clamping membrane, which promotes ultra-secure clamping with two supports on each side (fulcrums).
Ultimately, there is significantly less risk of tool pull out with CoroChuck 930, traditionally a frequent occurrence when using high helix tools. This unwanted effect is particularly troublesome in the aerospace industry when pocketing large aero-frame structures such as wing skins and ribs.
