Lathe machine’s handle operation introduction
Operating Handle Position
Operating position of the universal lathe:
1 The main motor “emergency stop” button.
2 The spindle shifting handle. There are three active positions for high, medium and low speed spindles and two zero positions to disengage the drive from the drive.
3 The threaded knob. There are two positions of “right-handed” and “left-handed”. When the spindle rotates forward, the handle should be in the “right-handed” position. When the spindle is reversed, the handle should be in the “left-handed” position, otherwise there is no feed, and the thread is not Subject to this restriction.
4 The pitch expansion handle. There are two positions of “J (basic pitch)” and “K (expanded pitch)”.
5 The spindle shifting handle. With eight positions, 2 and 5 handles, 22 spindle speeds are available.
6 The cooling pump motor switch.
7 The thread type change handle. There are metric (t) imperial (a) modulus (m) diameter section (p) four-bit towering.
8 (A) and 9(B) are the basic set handles for the feed box. Change the pitch ratio of the pitch or feed, and use the 8 and 9 handles together.
10 The double handle. The total pitch is multiplied and the feed is doubled in eight positions.
11, 14 Is the spindle joystick. Operate the spindle to reverse the rotation and stop the spindle rotation.
12 The slide box dial.
13 The opening and closing nut handle. Use for threading.
15 The tailstock handwheel. The mobile tailstock is used.
16 The tailstock quick clamping handle. Fasten the nut for the tailstock. When the tailstock is subjected to a large load, it is generally not used when cutting.
17 The longitudinal and horizontal feed handle of the tool holder. The longitudinal and lateral feed directions of the tool holder and the forward and reverse feed movements are all realized by the handle, and the rapid movement in the same direction is controlled by the buttons of the handle.
18 The small tool holder handle.
19 The main motor “emergency stop” button.
21 The main motor “start” button.
22 The square tool holder indexing and clamping handle.
23 The tool holder handle (middle slide handle). Manual lateral movement (rotated by a thousand handles and extended, be careful when operating the machine to prevent injury).
24 The slide box longitudinal handwheel: Use this handwheel when moving the tool holder vertically.
