BIG DAISHOWA has introduced MEGA ER Grip, a new premium ER collet chuck system featuring the best runout accuracy in the industry: .00012" (3 microns) at 5xD.
BIG DAISHOWA introduces the Perfect Jet Collet, designed to optimize coolant supply in high-speed operations, resulting in better coolant delivery and the option to seal the collet for coolant-through tools.
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.
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.
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.
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.
