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.
BIG DAISHOWA announces the introduction of the world’s smallest hydraulic chuck for HSK-E25 machine spindles, thus completing its extensive range of Slim Hydraulic Chucks.
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.
BIG DAISHOWA’s Mega ER Grip was designed to outperform all standard ER systems in the four most critical areas of tool holder performance: clamping force, concentricity, rigidity and balance at high spindle speeds.
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.
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.
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.
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.
