Spherical surface processing in high temperature stainless steel bearing

Stainless steel shell heat treatment within the sphere of high temperature bearing inner spherical treatment ( High temperature impact bearing adopts spherical data processing) : design and boring bar, used for the heat treatment of spherical bearing manufacturing. Installed on the lathe, the high temperature processing technology key consumer shell with common equipment. Tool rod 3 with shaft 4 installed in one long boring bar slot, boring bar 1 in three jaw chuck clamping way and with a special top 15 bearing. Clip is 5 on the other side of the cutting tools need to pass 2 pin shaft connected with connecting rod (6). Connecting rod 6 at the other end can pass are connected to the nut 8 pin 7. Turn the screw can make use of nut 8 boring bar 1 move in the dovetail groove. T20 1. 5 a left-handed screw 9 watts 10 hole in the rotation. Watts 10 from 16 fastening bolt in the boring bar 1 right end. Gear 11 m = 2 z = x = 31 - 0. 5 after flat key 12 washer 13 14 fixed on the screw nut 9 right end. Boring bar 1 rotates, gear 11 special top 15 rotate. Top 15 milling with m = 2 z = 12 x = 0. 5 teeth, so through the gear rotation, thus to drive screw rotation, 9 to 8 on the boring bar wire mother move yourself after pin 7 6 pin shaft connecting rod drives the cutter bar 3 and 2, centered on shaft 4 bit 5 of the boring bar long groove around the two arc move, so as to realize the processing of completed within the sphere. The first ordinary boring boring bar? On both sides of inner hole and end face, the operation method: the workpiece fastening on lathe big skateboard. Then use boring boring bar 1 at the ball. According to the spherical machining allowance and knife deep, confirm the length of 5 of the cutting tools, screw fastening tool bit. Mobile skateboarding, making the workpiece center alignment is the center of the shaft 4, tighten large skateboard. The spindle head 5 rotation from right to left, start cutting boring cutter and stop, shaking the slider take out tool rod, loosen the fastening screw, remove the segment, flip ( Face down) In the tool bar. To improve the appearance of the quality. Introduction to rough boring. Tool main deflection Angle and auxiliary f1 deflection Angle is 45 ° f. Boring is completed, the tip must be ground into r95 r100 rounded edge. The previous: high temperature stainless steel bearing has many advantages: next article no
