Custom gear machining involves manufacturing gears to precise client specifications, including unique tooth profiles, dimensions, materials, and tolerances. Processes like hobbing, grinding, shaping, and CNC milling are used to produce high-performance gears for specialized applications—such as robotics, Agriculture, automotive, or Automation. This approach ensures optimal fit, durability, noise reduction, and load capacity, offering flexibility beyond standard off-the-shelf gears.
Our engineering team conducts Design for Manufacturability (DFM) review, evaluating process feasibility, achievable precision, inspection methods, and potential risks.
Provide a detailed quotation and clear lead time based on the process route, material cost, inspection requirements, and production capacity.
Develop samples according to the confirmed drawing and process plan, strictly following forging, heat treatment, tooth processing, and grinding procedures.
Execute mass production according to the approved process standards, with in-process control and in-machine measurement at key stages to ensure consistency.
Perform final inspection (100% or sampling) and provide accuracy reports, hardness profile reports, and dimensional inspection records.
Perform dedicated packaging as per customer requirements to ensure tooth surfaces are protected during transit, and deliver on schedule.
