BIG KAISER to Showcase Milling and Turning Solutions at EASTEC 2017

BIG KAISER, a leader in high-precision tooling systems and solutions, will showcase a new super-slim milling chuck and a boring bar dedicated to eliminating vibration and maintaining an efficient cutting speed at EASTEC 2017, Booth 5248. The manufacturing exposition will take place on May 16-18 at the Eastern States Exposition in West Springfield, Massachusetts.

HMCJ, the newest addition to the HMC series, is a super-slim milling chuck with a peripheral coolant supply, designed to support heavy-duty and finish end milling tasks with power and precision using Ø1/2” or Ø12mm cutters. It features a clamping bore with fine slots surrounded by hundreds of needle bearings, which ensures concentric, precise and smooth clamping when the nut is tightened. The HMCJ applies the highest gripping force to the cutting tool shank of any comparable milling chuck in its class, and five to six times greater compared to collet chucks.

BIG KAISER will also highlight the Smart Damper boring bar for lathe applications. A heavyweight, strengthened damping mechanism integrated into the tool holder functions as both a dynamic counter and friction damper. It instantaneously absorbs vibration and eliminates chatter helping to achieve higher machining accuracy, better surface finishes and increased metal removal rates for higher productivity at critical machining depths. It’s also designed with the capability of supplying coolant through the body directly to the cutting edge.

The Smart Damper boring bar features three modular insert holders, optimized for right-hand I.D. turning with ISO standard inserts at a minimum diameter of Ø1.58”. Metric bodies are available in Ø32 and 40mm, with inch versions at Ø1.250 and 1.500”. With this system, boring at depths of approximately 7xD is well within reach.
