The firm says that setting time is substantially reduced with the Gewefa design featuring a spring plunger mounted in the toolholder body. This locates into a fine groove machined into all Sandvik EasyFix boring bar shanks and aligns the bar position precisely for the correct centre height. Along with the hydraulic chuck operation, a secure grip is guaranteed with integral anti-vibration damping to optimise the machining process.
Gewefa also offers a system for other proprietary systems with the ground angle on the back end (of the bar) locating against a stop pin at the base of the toolholder. This ensures precise central positioning and orientation with the bar then locked into the hydraulic chuck.
It says that the advantages of all systems is a 50% increase in cutter life due to the more secure, vibration-free grip, guaranteed repeatability when changing like-for-like bars and a simple, fool proof fitting process.
Gewefa offers the hydraulic chuck for ARNO, System Dieterle, DTS/HOBE/MAS/SUMITOMO/SANDVIK/ SIMTEK and VARGUS screw orientation options along with other systems.
