The mid-size diameter and adaptability to custom fixture designs make the Unilock 138 series BIG DAISHOWA’s best-selling round chuck workholding solution.
BIG DAISHOWA has launched the HMCJ, a super-slim milling chuck with peripheral coolant supply, designed to support heavy-duty and finish end milling tasks with power and precision using Ø1/2” or Ø12mm cutters.
There are three particularly sensitive areas of the tool holder assembly that can experience process-affecting wear and tear and cause a cycle to change.
Tool holders play a critical role in connecting elements maximizing machining performance, however, several different styles are available and the most suitable one will depend on the operation.
Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.
BIG DAISHOWA is introducing the RBX12 Air Power Spindle, a high-speed air-driven spindle that achieves an impressive variable rotational speed of 100,000-120,000 RPM.
When that inevitable job arises that requires higher RPM output, operators are left with the choice of replacing the machine altogether to gain higher productivity, or looking into an attachment, like a spindle speeder, to close the RPM gap.
The medical industry pushes the limits of precision for machining and tools. The trend toward less-invasive surgery using smaller parts translates to a need to better control the precision and tolerances of micromachining processes.
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.
BIG KAISER expands its product line, bringing the highest quality, most precise, most reliable and most accurate tooling and accessory products to market.
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.
