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.
When it comes to dialing in an ER system’s performance to match a specific application’s requirements or long life, there are three components to consider: the collet, the body of the holder and the nut.
ER nuts are basic nuts with surface treatment for friction reduction. They have slots on the outside diameter and use a spanner wrench for nut tightening.
Understanding and controlling runout is crucial for any machine shop looking to maintain competitive advantages in today's precision-driven manufacturing environment.
