When 25 ～ 6mm, show according to sign place, the rotate speed of main shaft must be pulled go up to middling speed archives, b of feed box handle is in the position of Ⅰ , c is in the position of Ⅱ . Turning of lathe of 1C620 of watch requesting an audience increases the sign of pitch whorl. Our aborning fumbles, turning lead is for 13 ～ 24mm and modulus 3.
When the whorl of 25 ～ 6mm, should adjust feed box handle B to be in only the position of Ⅰ , c is in the position of Ⅱ , main shaft rotate speed is pulled to low gear, the sign place that if express 2 ourselves place,revises is shown. Such, when finish machining, can use low speed turning, reduce vibration, reduce exterior surface roughness, improve the treatment quality of workpiece. Express 1 metric whorl to exchange gear 42:100(increases pitch) 32:9 of gear of modulus whorl exchange7(increases pitch) the A of each handle position of the gear case of each handle position of gear case moves to move to metric position handle of shift of box of feed of Ⅱ of Ⅰ of Ⅱ of Ⅱ of Ⅱ of Ⅰ of Ⅱ of Ⅱ of C of Ⅱ of Ⅰ of Ⅱ of Ⅰ of Ⅱ of Ⅰ of Ⅱ of Ⅰ of metric position B 11326521043.
