Defend Promise with Life, Build Future with Quality.
1. IQC: Including component analysis and specification testing
1.1 Component analysis: Check whether the content of the purchased steel sheets and alloys meets relevant standards and production requirements.
1.2 Specification analysis: Including equal thickness tolerances, hardness values, profile inspections, etc.
2. IPQC：Each process of the production must be tested.
After each production process, the product needs to be tested. Includes tempering, stress detection, two times of leveling and two times of dynamic balances test.
Need to detect items including sharpening accuracy, flatness, end jump, ridial jump, tooth jump, center hole size, tooth shape and etc.
4. Simulation Processing
For different products, purchase common equipments for simulation processing to test the cutting tools use effect.
