During the precision machining process of mold components, the quality can be directly affected. Proper control of precision machining effectively reduces part deviations and scrap rates while improving the first-pass success rate and service life of mold components. Therefore, implementing strict quality control during precision machining is crucial. Below, XP MOLD explains key considerations:
The heat treatment process must not only achieve the required hardness but also control internal stresses to ensure dimensional stability during machining. Different materials require specific treatment methods.
Grinding operations primarily use three types of machines: surface grinders, internal/external cylindrical grinders, and tool grinders. Precision grinding must strictly control grinding deformation and cracks—even microscopic cracks may become apparent in later production. Therefore:
Use minimal grinding depth
Ensure sufficient coolant
For tolerances within 0.01mm, employ constant-temperature grinding
(1) Custom Mold Components
Adapt machining techniques based on material properties and requirements, leveraging process flexibility for optimal results.
(2) Component Classification
Parts can be categorized into shafts, plates, and complex shapes, with a general process flow:
Rough machining → Heat treatment (quenching/tempering) → Precision grinding → EDM → Benchwork (surface treatment) → Assembly
