Precision Machined Components

Systematic Design Thinking

Before manufacturing Precision Machined Components, Sanluo Precision's processing plant uses SolidWorks or CATIA to complete 3D assembly simulation and identify potential problems such as interference, clearance and stress in advance. A unified datum processing scheme is adopted for mating surfaces, positioning holes and datum planes to ensure positional accuracy. For mating parts, the selective assembly method (mating according to actual dimensions) or group processing method (consistent process parameters for the same batch) is used to ensure interchangeability. The fit of key mating shaft holes is H7/h6 (transition fit), the gear meshing accuracy is grade 6-7 (GB/T 10095), the coaxiality of bearing housing is 0.01mm, and the thread connection fit is 6H/6g.

Assembly and Test Verification

There is a professional assembly workshop for Precision Machined Components, which uses tooling equipment such as torque wrenches, press-fitting machines and alignment instruments, and strictly implements the assembly process card. The interference of bearing assembly is controlled within 0.005mm to 0.015mm, and hot or cold assembly is adopted to prevent damage to the mating surfaces. The gear meshing clearance is adjusted between 0.15mm and 0.35mm during gear assembly, and the contact spots are checked by the coloring method, with more than 60% in the tooth length direction and more than 40% in the tooth height direction. Functional tests are conducted after the component assembly is completed, including no-load test run of transmission mechanisms (noise, vibration, temperature rise), pressure test of hydraulic systems (holding the working pressure for 30 minutes), and air tightness test (helium mass spectrometer leak detector, leakage rate ＜10⁻⁶Pa·m³/s).
