Southern Large Aperture Lathe can rough and finish machining the inner and outer cylinders, cones and other forms of rotating surfaces of ferrous, non-ferrous and non-metal workpieces; it can turn a variety of commonly used metric, inch, modulus, pitch thread and multi-thread ; Can perform drilling, grooving and broaching of oil grooves.
It can be used for large-pitch thread turning, and the spindle diameter is Ф82, which is also suitable for processing large-diameter pipe parts.
When turning on a lathe, the roundness error is not greater than 0.01mm, the cylindricity error is not greater than 0.01mm on the 100mm measurement length, and the surface roughness (Ra) is not greater than 25μm; the precision of the precision turning thread test piece is on the pitch of 300mm length The error is not greater than 0.06mm; it is driven by a fast motor, and the vertical and horizontal movements of the tool holder save the processing auxiliary time. The tailstock uses a roller to move, so that the entire tailstock moves more quickly.
This series of lathes has a wide range of process performance, suitable for single parts, small batch production workshops, tool manufacturing departments, machine equipment repair departments and test laboratories of general machinery manufacturing industry.
The machine tool has a guide rail span of 390mm. It has the advantages of good rigidity, high precision, easy operation, low noise, versatility and good appearance.
