WELDING TABLE LEGS: 670 X 90MM 4PC SET FOR HK TABLES

* This welding table is manufactured fron one piece cast iron (HT200-250) with fine mill Finish, finishment 3.2 * Casting surface hardness to HB170-240 * Comes with 28.0mm holes

* This welding table is manufactured fron one piece cast iron (HT200-250) with fine mill Finish, finishment 3.2 * Casting surface hardness to HB170-240 * Comes with 28.0mm holes

* Diimensional assembly worktable D28 series, on the high precision table, every 50mm/100mm interval distributes the D28mm circular hole * These holes can be used for holding down workpiece for utmost accuracy * Working plate made of hardened die steel, specially treated with plasma nitriding on surface previnting rust and scratching, hardness HV≥ 550 Table accuracy: flatness ≤ 0.1mm/㎡, verticality ≤ 0.1mm BENEFITS OF STEEL: * Hardness increase, smoother surface. cleaner etching lines. Note: Spatter resistance is achievable with nitriding treatment. * Hardness: Differs per treatments: Standard and Burnishing ~250HV. Nitriding ~550HV. * Dessity: 7.80 g/cm³. * Tensile Strength: 355 MPa.

* Ball lock is an ideal fitting for connecting parts on welding equipment, using the connection with different materials and different thickness parts * * QSP28060 effective clamping distance is 45-55mm * * QSP28085 effective clamping distance is 70-80mm * * The O-ring on the positioning shaft acts as a dust-proof, fastening and positioning function. * The movement of the steel ball from the inside to the outside makes the locking force gradually stronger *
