Designed with an ideal combination of total indicated runout (TIR), clamping force and ease of use in mind, the new REGO-FIX micRun clamping system is an accurate collet system for high-speed machining.
REGO-FIX developed the micRun system for superior, high-precision clamping. It's available in standard taper types and comprises three precision-tailored and matched components: micRun collets, micRun clamping nuts, and micRun toolholders. When used together in compliance with recommended tightening torque, the components create higher transferable torque compared to other precision collet systems and provide a TIR of less than 0.00012" at 3 times diameter, according to the company.
Available with internal or peripheral cooling, micRun features a patent pending collet locking system that retains the collet in the nut for easier insertion and removal, with no extractor required. The micRun line of collets provides great flexibility with four sizes available: MR11, MR16, MR25, MR32. It also allows 16 different tool diameters ranging from 1.00 to 20.00mm to be clamped in the same holder, including tools with nominal diameter with shaft tolerance h11.
micRun Clamping Nuts have a special surface treatment that increases the clamping force, and a special thread design keeps the nut aligned with the holder to improve repeatability and rigidity in challenging applications. The nuts, which also have a closed contour design that reduces noise, can be tightened and loosened with a freewheel wrench head. The nuts are available with standard (MR) and fine thread (MRM), and coolant versions for Coolant Flush Disks and Sealing Disks (MRC).
Related Glossary Terms
- collet
collet
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
- total indicator runout ( TIR)
total indicator runout ( TIR)
Combined variations of all dimensions of a workpiece, measured with an indicator, determined by rotating the part 360°.
