BIG DAISHOWA has introduced MEGA ER Grip, a new premium ER collet chuck system featuring the best runout accuracy in the industry: .00012" (3 microns) at 5xD.
With sizes ranging from 41 to 203 mm, the EWE digital boring head for fine boring features a large on-head display and connects to the BIG KAISER app making extremely precise bores easier than ever.
Cleanliness is key to achieving good runout control when assembling tool holders. Small particles or oil in a tool holder can cause large runout of the cutting tool, deceasing tool life and performance.
