SPP Industry | SPP Industry in Chengdu
Chengdu Branch Factory
The factory in Chengdu, Sichuan Province, covers an area of 11,500 square metres. It is a factory that designs, develops and produces mainly spindles and hydraulic components, and provides precision machining services, and is a major provider of precision grinding and honing technology in Southwest China.
CNC turning and milling equipment
Precision components manufacturing thanks to state-of-the-art facilities
Spindles are manufactured using components from our Precision Components Division, which ensures spindle quality and traceability at every step of the process. We supply spindles and precision components to the world’s leading machine tool manufacturers, thanks to our state-of-the-art facilities.



Precision Grinding and Honing Equipment
The highest precision comes from precision grinding
The manufacture of spindles and shafts requires extremely high cylindricity and runout. Our STUDER and KELLENBERGER CNC grinding machines control the tolerances of the outer diameters to a maximum of 0.001, and the entire process is controlled in accordance with the ISO 9001 standard. Stringent bore requirements are fulfilled by DMG MORI vertical grinding machines and NAGEL honing machines, which are able to achieve a surface finish of ra0.02 and concentricity of 0.001.




Assembly and Testing
Testing and assembly spindlesarea for precision
Chengdu factory of SPP focuses on the R&D and production of CNC machine tools and core functional components such as tool magazines, spindles, rotary tables, etc. At present, the company’s main products include: dual-exchange horizontal CNC rotary tables, vertical and horizontal CNC rotary tables, hydraulic tool magazines, disc tool magazines, electric spindles, lathe spindles, belt spindles, five-axis, four-axis, etc. Since its establishment, the company has invested heavily in the purchase of production equipment and inspection equipment.




Measurement
Excellent quality assurance system and process control system
We have imported testing equipments such as German Zeiss CMM, Japan Tokyo Precision CMM, Sweden Hexagon CMM, Swiss TESA height gauge, UK Taylor Hobson true roundness gauge, Japan Mitutoyo hardness tester, 3D profiler, height gauge, UK Renishaw laser detector, etc. The workshop is in 24 hours constant temperature and humidity environment, and combined with our ERP system, we can trace back every step of process control.
