Because of rapid industrial development and the constant evolution of products in all areas of the economy, higher and higher machining standards of efficiency and accuracy are demanded. The STC1135 and the STC1835 pipe threading lathes have been developed relying on our own long production experience and incorporating the technology of similar machines both in domestic and foreign industry, keeping in consideration the needs of the marketplace. These machine tools are characterized by their economy and high efficiency, and are the first choice for machining pipe and couplings by the petroleum and steel industries.
These CNC pipe threading lathes, with their modern electro-mechanical integration reach a machining accuracy standard of IT7, with surface finish of Ra 1.6.
The headstocks are of two types of configuration: one with 8-step spindle speeds, two-speed motor, two-way hydraulic clutch, two electromagnetic clutches, and automatic speed-shifting system through all 8 speeds; the other configuration incorporates a main spindle servo motor which permits CNC controlled step less speed regulation.
