The lathe is the multi-purposed process lathe which can perform multi-time repeat circular process, it is special suitable for military, tractor, petroleum, pump and automobile industries machinery machining. It mainly burden semi-finishing and finishing process for shaft parts, disc. Parts. It can turn external and internal cylindrical surfaces, taper, thread, boring, reaming as well as various curved surface rotary parts. This machine adopts modularize design and can equipped with different devices and attachments as per the user's requirements.Structure characteristics: 1. The bed adopts the horizontal plane type and guideways are treated by middle frequency harden for high rigidity. The slide surface of saddle is coated by TSF guideway plate, which has the features of perfect anti-abrasion, flexible motion and stable precision. 2. The important mechanical parts are to be strengthened for high rigidity. 3. Main transmission adopts double speeds motor and speed change by us of electro-magnetic clutch (the universal motor equipped with frequency change device for the stepless speed change is optional)4. The tool holder adopts the serrated-tooth position for high repeatability and high rigidity. 5. The feed system adopts step motor or servomotor for driving ball screws. The gears with the structure of remove the clearance can be adopted for high precision of transmission.6. The layout of lathe shows mechanical, electric and cooling all in one structure for smooth appearance.7. The lathe adopts modularize design, different configurations can be selected. 8. The controller adopts FANUC 0-TD system of Japan.9. the tool holder has vertical 4-positon, 6-position or horizontal 6-position or more.10. Manual, electric or hydraulic chuck can be offered as well as tailstock Standard configuration: manual chuck, vertical 4-position tool holder, mechanical tailstock, and spindle 8 grade speeds, semi-enclosed protection.
