Feature of C6140 manual lathe machine
It can be used for turning cylindrical and conical surfaces, end faces and inner holes, as well as a variety of metric and inch threads.
1. Spindle: through the diameter of 52MM, in line with the international standard ISO-C6; expand the scope of shaft processing.
2. Square tailstock: The tailstock has a fast cam clamping device, which has high working efficiency. There is a device in the tailstock sleeve to prevent the rotation of the drill bit, which avoids damage to the taper of the inner hole of the tailstock sleeve due to the rotation of the drill bit caused by misoperation, and effectively protects the tailstock components.
3. Guide rail surface: adopts numerical control super audio frequency quenching and peripheral grinding, which has the advantages of high precision and good wear resistance.
4. The head gearbox adopts Harbin bearings in a complete set, and the spindle adopts Harbin BEARING high-precision double ball bearing support to ensure the accuracy and stability of the spindle during high-speed rotation, which creates necessary conditions for the manufacture of CNC lathes.
5. Chuck: The metal three-jaw chuck is the standard configuration of the lathe, and other chucks can be selected, which is helpful for tightening. Objects with different rules are conducive to processing and rapid production.
6. The width of the guide rail is 400mm, the quenching depth is 4mm, and the wear resistance and stability are high.
Inspection before driving of ordinary lathe
1. Add appropriate grease according to the lubrication chart of the machine tool.
2. Check all electrical facilities, handles, transmission parts, protection and limit devices are complete, reliable and flexible.
3. Each gear should be at the zero position, and the belt tightness should meet the requirements.
4. It is not allowed to store metal objects directly on the bed surface to avoid damage to the bed surface.
5. The workpiece to be processed is free of mud and sand to prevent mud and sand from falling into the carriage and damaging the guide rail.
6. An empty test run must be carried out before the workpiece is not clamped, and the workpiece can be installed after confirming that everything is normal.
