Toolholders & Collets

Emuge Corp., West Boylston, Mass., a manufacturer of taps, thread mills, toolholders, clamping devices and other rotary cutting tools, today announced the expansion of its patented Softsynchro® tap holder line, adding two new holder sizes.

BIG KAISER Precision Tooling Inc., Hoffman Estates, Ill., this month introduced the RBX12 Air Power Spindle, a high-speed, air-driven spindle said to be capable of achieving a variable rotational speed of 100,000rpm to 120,000rpm, according to a BIG KAISER news release issued Jan. 18.

Even with minimal runout near the nose of the holder, conventional collet holders frequently see larger runout when measured at the cutting edge of longer tools. NT Tool's original "R" Zero system eliminates this problem by utilizing a four-point adjustment mechanism to adjust runout at the tool tip to as low as 0µm to 2µm.
