Pull rod installs clip collet general assembly to pursue quickly my factory uses roller of bearing of turning of lathe of roller of special hydraulic pressure so, outfit of move back and forth places take time, and the labor strength that increases operation staff. Additional, noise of machine tool movement and capacity of bad news oil are great, affect the job and environmental sanitation badly. For this we undertake the collet of lathe be improvemented entirely () seeing a picture. Of the collet after improving inside swivel nut 1 load lathe main shaft 9, clamping apparatus 6 rely on pull rod 10 after adjusting, the swivel nut outside making 2 with bearing 4 rotate not to jockey to be placed into luggage. Take out share of unit of hydraulic pressure system, got rid of " oily mouse " , can save many complementary material cost every year. The N=1400r/min of the biggest rotate speed of the main shaft after improving, collet movement is smooth, without noise, ceaseless car can undertake holding clip quickly, shortened greatly the time that hold clip, reduced labor intensity. This collet applies to treatment bearing N326E of ～ of N314E of 2 types roller and 3 types roller 22210 ～ 22244, 22308 ～ 22330, to different type roller treatment simply changes clamping apparatus can be used. The circle outside still applying to a car, flat end panel, hit heart aperture to wait, can improve work efficiency 5 ～ 6 times. CNC Milling
