CMM Inspection: Ensuring Zero Tolerance in Heavy-Duty Brake Caliper Machining Dimensions
For air disc brakes, the coaxiality of the caliper bracket and the piston hole, and the perpendicularity of the guide pin hole, these dimensional tolerances are usually required at the micrometer level. Once the machining dimensions exceed the standard, it will cause uneven brake wear, or even trigger serious consequences like brake deviation.
How to define a high-quality heavy-duty brake caliper?
Heavy-duty brake calipers bear immense pressure in high-speed commercial vehicles. If the ratio of carbon, silicon, and manganese in the cast iron material is incorrect, the caliper body may develop micro-cracks or even break under extreme braking.
Why We Conduct Real-Machine Simulation Testing on Every Batch of Friction Linings?
In the North American RV and utility trailer market, 10-inch and 12-inch electromagnetic brakes are mainstream. Many buyers only focus on price, but as a factory with 10 years of export experience, we pay more attention to the fade rate of friction materials under high-frequency braking.
