Precision processing of high-precision parts for colour steel tiles

ETCN has long-term cooperation with WASI in Poland on the color steel tile equipment project, focusing on providing high-precision equipment parts. We meet all the customer requirements for parts with excellent precision and outstanding appearance. This case study shows how we complete producing such high-precision parts.

According to the customer’s drawing requirements, the overall tolerance of the product is +/-0.01mm. In milling, we need to ensure the machining accuracy and form tolerance of the product, which is completed in the following steps: casting – rough machining – normalizing – tempering – semi-finishing – stress relief – finishing – packaging

Precision milling on high with precision gantry CNC and horizontal CNC machining centres

ETCN uses high-precision gantry and horizontal CNC machining centres to achieve an optimal tolerance of ±0.005MM. After machining is complete, we use three-coordinate, micrometer and dial indicator testing tools to accurately check all dimensions to ensure that the product meets the requirements of the drawing and that the parts meet strict quality standards.
