1. Product Description

CNC Machine Tools are high-precision automatic processing equipment classified under auxiliary and support equipment, serving as essential supporting machinery for the precision manufacturing of oilfield equipment and industrial mechanical components. This product series covers slant bed CNC lathes, Vertical machining centers, surface grinders, cylindrical grinders and heavy-duty horizontal lathes, widely used for processing core oilfield parts including Sucker Rods, rod couplings, downhole tool shells, valve components and tubular connectors. Adopting digital numerical control technology, these machine tools replace traditional manual processing methods, realizing fully automated turning, milling, drilling, boring and grinding procedures to deliver high precision, consistent dimensional tolerance and excellent batch production stability.

All CNC machine tools adopt integral cast iron bed with secondary stress relief annealing treatment, effectively eliminating internal structural stress and preventing long-term processing deformation under heavy load operation. Equipped with high-precision ball screws and linear guide rails, the equipment features low friction, stable feeding and outstanding repeat positioning accuracy. Optional world-class control systems such as Siemens and Fanuc support multi-axis linkage, automatic tool change and program cyclic operation, enabling unattended continuous processing of complex shaft parts, sleeve parts and irregular structural components. Customized fixtures and exclusive processing programs can be configured according to oilfield production demands, perfectly adapting to thread turning, outer circle finishing and ultra-precision surface polishing of various artificial lift equipment accessories.

Tailored for harsh industrial processing conditions, this series of machine tools is compatible with carbon steel, high-strength alloy steel, stainless steel and anti-sulfur corrosion alloy materials. The whole equipment features rigid structure, low operating noise and low failure rate, effectively improving production efficiency, reducing manual operation errors and cutting long-term processing costs. As standardized auxiliary supporting equipment for global oilfield machinery manufacturing projects, CNC machine tools ensure the processing quality and assembly accuracy of downhole equipment, providing reliable technical support for mass production of oilfield supporting parts.
