R8 Shank for ER32 Collets. Drawbar End: 7/16"-20 Hardened and precision ground. Max TIR 0.0002" O.D to I.D This is an ultra-precision workholding tool. When doing the inspection to ensure that each part is wiped especially clean, and the installation must be in place, otherwise it has a great impact on the accuracy When testing, whether the user's machine tool spindle has errors on the accuracy also has a great impact. So you need to ensure that the accuracy of the spindle of the user's test machine must be high. In addition, please make sure that the accuracy of the ER collet must be high, many ER collets are marked as 0.0005", many of them cannot reach it. If the accuracy of the collet in the hands of the customer is low, the accuracy of our toolholder is no longer high enough to detect the accuracy. R8 Shank for Manual Milling: Perfectly fits machine spindles with R8 taper, enhancing milling precision and stability. ER32 Collet Compatibility: Holds tool diameters from 0.08" to 0.787", offering versatility for various machining tasks. High-Grade Tool Steel Construction: Ensures durability and resistance to wear, extending the chuck's lifespan. Ultra-Precise T.I.R. Rating: Maximum T.I.R. of 0.0002" O.D to I.D for unparalleled accuracy in tool alignment and surface finish. High-Speed Capability: Designed for use up to 8000 RPM, suitable for both high-speed and precision milling operations.

Diagram Specifications Gage Length (L): 2.48" Collet Nut Diameter (D): 1.97" Drawbar End(d1) Thread: 7/16"-20 Collet Capacity: 0.08"-0.787" Accuracy Inspection Cautions Clean All Parts: Dirt or improper installation affects precision. Check Spindle: Ensure your machine?s spindle is highly accurate. Use Quality Collets: Many marked 0.0005" don?t meet the spec. Overall Accuracy Depends: Low collet accuracy limits test results. Attention: Eccentric Ring of the ER Collet Nut Collet Nut's Eccentric Ring The Eccentric Ring is designed per the requirements listed in ISO 15488:2003(E). It is to hold ER collets in place. Assembly Tilt and insert the collet partway into the nut. Engage the ring into the collet's groove and press until fully seated. Assembled Tighten the nut lightly with the collet holder. (Warning: never tighten the nut without a cutter in it as it will break) Disassembly Take out the nut from the holder. Press the end of the ER collet until it disengages from its position. Push the collet out of the nut.
