We’ve seen and heard it all when it comes to boring holes. That said, there are always a few questions that pop up over and over. From optimizing modular boring assemblies to deciding between twin boring or high-feed milling, here’s some of our best boring advice.
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.
Anyone who’s made holes understands the difficulties that can arise: vibration, wander and even breakage. When it comes to production-level volume, these issues become even more limiting. Many turn to helical interpolation with a mill as a reliable way to rough out holes. We’re here to tell you there’s a faster, easier option.
Keeping pace with modern manufacturing demands often means bridging the gap between design and production. Creative and resourceful applications of tooling and accessories, such as angle heads, can get complex parts out the door.
Smart Damper products are designed for deep-hole boring with BIG KAISER’s CKB modular boring system, and also for extended reach milling with both inch- and metric-pilot shell mills and face mills.
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.
Machining vibration disrupts efficiency, reduces tool life and damages part finishes. Solving it isn’t easy as causes are varied and interconnected. Discover strategies to tackle vibration for better results.
Moldmakers hoping to avoid problems such as chatter, poor tool life and molds that fail quality control muster need to consider a variety of factors when selecting a long-reach toolholder.
