Anca collet adaptor maintains less than 7 micron runout

Anca’s second-generation PremierPlus collet adaptor technology is designed to ensure consistent and efficient tool runout. With three times greater clamping force, tools are held more securely when grinding, increasing the consistency of tool geometry across a batch run. As the clamping force is increased, more force is required to open the collet, a factor enabled by a hydraulic pressure intensifier unit at the rear of the PremierPlus adaptor.

Simon Richardson, product manager, says: “The PremierPlus has been designed to control tool runout as it enables operators to radially adjust the collet via adjustment screws. As the clamp force is pre-set via the preload of the clamping mechanism inside the adaptor, the operator does not need to remove the adaptor from the machine when changing the collet.

“Simplifying the grinding process reduces set-up time and saves money,” he adds. “Adjusting the preload of the internal clamping mechanism ensures that larger diameter tools can be rigidly held, particularly when fluting tools at higher grinding forces.”

The latest PremierPlus system can be retrofitted for existing Anca MX, TX and FX machines in the field, without any need for modifications to the machine headstock.
