Product Description
Application
This model is designed to meet the special requirements of users in the petroleum, geological, mining and chemical ndustries, and in agricultural irrigation and dranage. It is able to cut CZPT straight and taper pipe threads of union joints, drill rods, casting pipes, drain pipes, well casings and water pump pipes more economically and efficiently as compared with the engine lathe. However, it may serve as an engine lathe to cut CZPT metric, Whitworth and module threads, shafts and disks. After all it is an ideal machine for the petroleum, mining geological, chemical and agricultural industries.
Features
1. The machine is able to cut outer and inner threads of Straight and taper pipes up to 430mm in diameter.
2. The machine is equipped with a tapering unit which can works out a 1: 4 taper.
3. The machine is able to cut both metric and Whitwith threads without changing the translating gear.
4. The dropping worm in the apron can protect the mechanisms of the lathe automatically.
5. The guide way is hardened and finely finished.
6. The great CZPT of the machine is competent at heavy load and CZPT cutting.
7. The floor center rest can be moved freedy as required by the user. The center rest is provided with an adjustable clamp unit for CZPT pipes, greatly reducing labour.
8. The 4-jaw head stock offers free clamp of both short and CZPT pipes.
