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 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.
Shrink-fit and hydraulic holders are both useful in low clearance, tight work envelopes found in moldmaking and multi-axis machining applications. When deciding which one to use, their differences will guide your choice. Here are some of the fundamental contrasts to help you decide which holder type is best for your work.
As cutting tool manufacturers increase the recommended operating conditions for their products, users achieve the desired result: shorter cycle times on existing machine tools.
If you purchase cheap dual contact tooling after being told by a supplier that it will work just as good as the original you risk unsatisfactory performance.
The BIG DAISHOWA SPHINX drill series includes more than 2,000 different drills under 3 mm in diameter as standard. With a range of 0.05 to 3 mm diameters.
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.
With the addition of the Fullcut Radius Mill and the Ball End Mill, the Fullcut Mill Contact Grip series now features four connection sizes and seven cutter types.
BIG DAISHOWA recently joined Okuma America Corporation’s Partners in THINC network, a collaborative network of 40+ companies that service the metalcutting and manufacturing industries.
