Cheater bars are appropriately named, especially when it comes to tightening tool holders. We see the common pipes that are often added to the end of wrenches to achieve more torque in customers’ shops all the time. And while these makeshift wrenches may make tightening or loosening holders easier, the damage they can cause is often overlooked.
Pullout is a major issue facing manufacturers using milling chucks, especially when machining heat-resistant super alloys (HRSA) like titanium or inconel
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.
