【 Jiaxing bearing group co. , LTD. ) Bearing sleeve machining cutting parameter how to choose? Don't hurry to learn together with the author there is rotation, has the HRB bearing ( ) For bearing sleeve machining cutting dosage, jiaxing bearing group co. , LTD. The author want to speak today greatly, also don't hurry to my dear friends. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. ( 1) Turning amount of choosing rough machining, in the process system rigidity and permission of machine tool power, as far as possible, take a larger quantity of turning, to reduce the number of feed; Finishing, in order to ensure the parts machining accuracy and surface roughness requirements. According to the processed surface quality, cutting tool material, workpiece material and machine performance, refer to the manual cutting dosage or relevant materials selection: coarse outside contour & alpha; P = 2 mm, semi finished outside contour & alpha; p = 0。 75 mm, fine car & alpha; p = 0。 4毫米; Rough boring & alpha; P = 1 mm, fine boring & alpha; p = 0。 3mm。 ( 2) Feeding of choosing rough machining, according to the processing of materials, the size of the tool rod, workpiece diameter and amount of turning operations have been identified, reference manual or relevant materials and combining the cutting parameter machine specification, selection: coarse car f = 0. 2 mm/r, rough boring f = 0. 15毫米/ r; Semi-finishing and finish machining, in accordance with the requirements for the surface roughness, according to the workpiece material, tip arc radius and cutting speed, select: half a fine car f = 0. 15 mm/r, f = 0. 1 mm/r, fine boring f = 0. 1mm/r。 ( 3) The choice of the spindle speed based on turning operations have been identified, feeding, cutting tool and workpiece material durability, reference manual or relevant materials, and cutting parameter table lookup to select cutting speed Vc, Vc = 120 m/min, coarse car half a fine car Vc = 130 m/min, fine car Vc = 140 m/min, rough boring Vc = 60 m/min, fine boring Vc = 70 m/min, and then use formula ( 2-5) To calculate the spindle speed. Vc=π dn / 1000 ( 2-5) Type: n to the rotating speed of workpiece and tool ( r/min) Cutting speed (Vc for m/min) D point selected for the cutting edge of the workpiece and tool of gyration diameter ( mm) Combined with practical experience, and ultimately determine the spindle speed is: rough machining, n = 600 r/min, n = 800 r/min, semi finished car car n = 1000 r/min, fine boring n = 700 r/min, threading, n = 500 r/min.
