Product Name: Precision Parallel Vise Model NO.: QJ Type: Stationary Material: Carbon Steel Shape: Without Anvil Jaw Width: 40 Application: Grinding Machine, Drilling Machine Certification: ISO9001:2008, SGS Trademark: Weihe Transport Package: Carton Box Specification: 40x32 Origin: China HS Code: 8466300000 Product Description XUELING Parallels are made from fine quality alloy steel, case hardened to HRC59-63. The tolerance is within 0. 01mm for height and width. Parallelism between one pair accords to IT5. By building these parallels into various sizes, they are convenient for Appling these machining.XUELING vises are made from fine quality alloy steel and high carton steel, heat-treated to HRC58-62. They provide flexibility applications in many ways and long lasting accurate performance.Mainly applied in the following range:Square grindingSmall parts multi-loading grindingSmall cylindrical parts profile-grindingStrip parts, non-ferrous metal and carbide parts grindingComplex shape profile-grindingBencher drilling, reaming, taping, lining and measuringLight millingXUELING angle plates are made from fine quality alloy steel, hardened to HRC59-63. They are applied in machining angle work pieties by assembling on the work-bench with T-slot.
