BIG DAISHOWA’s CNC collet chucks have a guaranteed runout at the collet nose of less than 0.003 mm at 4xD, and are available for all machine tool spindles.
The contract manufacturer Schittl from Deutsch Kaltenbrunn specializes in the production of one-offs and small series projects. Based on a recommendation from the multi-brand dealer Metzler, they use chucks from BIG DAISHOWA. This is their story.
Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.
The chances of a tool slipping or pulling out in its holder during work is increasing. Here are some insights to help you select the proper holder for your work.
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.
