MR CARTOOL Flange ndle Homemade Lathe 80 100 16mm-19mm Through hole shaft Car Repair Tool

Description：

80 flange ndle (excluding bearing pulley, bearing, ck) (applicable to k11, k12, k21)100 flange ndle (excluding bearing pulley, bearing, ck) (applicable to k11, k12, k21)Composite flange ndle (without bearing pulley, bearing, ck) k11, k12, k72, k21 models are common100 composite flange ndle (without bearing pulley, bearing, ck) k11, k12, k72, k21 models are common【s】ndle axis: The shaft diameter is 25, the total length of the flange is about 205mm, and the through hole is about 19mm. Because the hole of the 80th is only 16mm, the overall through hole after loading the is about 16mm. Hardne: HRc 55-62°The ndle adopts numerical control machining precision s: the vertical angle of the axial center and the flange end face is ≤0.03mm, the axial center and flange concentricity is ≤0.03mm, and the axial outer diameter tolerance is g6.K11, k12 default flange fixing holes 3, suitable for s-centering linkage ck.K72 default flange fixing hole 4, suitable for single-action ck.80-card flange main shaft, after installing 80 cks, the overall through hole is about 16mm.100 flange ndle,After installing 100 cks, the overall through hole is about 18-19mm.The main shaft and the flange are equipped with interference fit (tight fit) + the end face is fixed by spot welding. The interference fit and the shaft center are more accurate. Due to the small amount of spot welding, the ndle is le deformed by heat and will not be deformed. Reduce the accuracy of the shaft.The prince of gap matching precision debuing:After installation, the holds the standard rod, rotates the ndle, carefully observes the eccentric direction of the ck, marks the eccentricity, and then moves the in half in the opposite direction.Then turn the ndle and observe the eccentricity. If there is an offset, adjust it again as described above until it is satisfactory.
