Question:

Lathe machining slender workpiece should be matched with the knife

Lathe machining slender workpiece should be matched with the knife

Answer:

The reasonable choice of cutting parameters; turning slender shaft, the cutting amount should be less than the ordinary shaft parts, with the hard alloy lathe rough car and then left the amount of fine grinding grinding to size requirements.
Choose reasonable tool angle; in order to reduce the radial cutting force, should choose the larger main angle; the front cutter surface should be grinded chipbreaker R=1.5-3mm, the chip flow surface to be machined; the tool surface roughness to be small, and keep a sharp cutting edge.
The utility model relates to a tool holder, which is used as a universal tool for a lathe, which is used for supporting the workpiece near the cutting point of the cutter and longitudinally moving with the tool carriage. Contact with the tool and the workpiece support at a general wear resistant ductile iron or bronze, circular support, should be in the car with coarse cylindrical grinding, so as not to scratch the workpiece, the turret can affect the radial cutting force and workpiece weight offset processing, thereby reducing the deformation of workpiece and cutting vibration however, careful attention must be paid to the adjustment, consistent with the tool center and machine center.
In the process of turning slender shaft, the clamping method of one head and one head is adopted. When the workpiece is clamped by a chuck, an open air coil is sleeved between the clamping claw and the workpiece to reduce the axial joint angle of the workpiece and the clamping claw. The tailstock with elastic top, so when the workpiece by the cutting heat and elongation, thimble axial expansion, with the form of compensation for the work of the pavilions, reduce the workpiece bending
Must be used with the turret, the key technology in the turning of slender shaft is to prevent bending deformation in machining, so it must be from the fixture and machine auxiliary equipment, process, operation technology, tool and cutting measures.
