Precision Machining
Precision Machining

Starting from machining  and dedicated to machining for 30 years, Qianhao is matchless regardless of technology, equipment and capacity in the industry.


Machining operation is the core and biggest competitiveness of Qianhao It is not a workshop, but two factories which has been equipped with advanced and complete equipment, and has a complete management team. There have in place independent engineering team, production team, QA team and Supply Chain team to support its activities. The machining blanks cover raw (steel) castings from Huawei foundry and outsourced iron castings, forgings, profiles, etc. The company's powerful machining capabilities is the strong pillar for providing customer with precision machined castings & forgings and profiles.Our capabilities include turning, milling , tapping, broaching, drilling, & many other processes to fit your needs.


With state-of-the-art equipment and unmatched technical expertise, we turn ideas into reality. Our high quality, precision machining centers and CNC lathes give us great reliability and continuously produce quality parts. Our typical CNC machining cell is made up of two or three machines (lathes or machining centers) under the control of a single operator allowing us to produce components efficiently and at competitive costs. The capability to manufacture our own linings for many of our products strengthens our versatility.


To ensure the highest quality of the finished products, the use of computer programs is critical. CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) programs provide detailed blueprints about each step of the precision machining process. Programs like ProE and UG create extremely detailed three-dimensional blueprints. Precision machining can be used on many materials, including steel, iron, aluminum, copper, bronze, and some special alloys.
