Have you had a chance to read our recent article that appears in the Fabricating & Metalworking Magazine? Alan Miller, informs readers about different ways to absorb synchronization error.
Chattering and deflection have always been the bane of machinists’ existence, so much so that the sight of a long and slender tool holder will immediately cause goosebumps. If you understand why a long tool holder behaves the way it does, you’ll know that there are ways to fight back against this bending.
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.
The first challenge to machinability – beyond simply working in titanium – for Colorado-based Cogitic Corporation was securing the cylinder in the universal machining center. It was also important to maintain access to the through-hole, which has an internal square key slot perpendicular to the stem hole.
Insufficient retention force of the spindle clamping mechanism could lead to reduced rigidity and vibrations, loss of machining quality, poor surface finish and shortened tool life. To help solve this problem, we have developed Dyna Force, a device for measuring the retention force of machine tool spindles.
Many factors may go into the decision to invest in a presetter such as tool budget, accuracy needs or delivery time. We’ve put together a reference guide.
Pullout is a major issue facing manufacturers using milling chucks, especially when machining heat-resistant super alloys (HRSA) like titanium or inconel
