Large Diameter CNC Turning

Turning large diameter parts requires strong machines, tough tools, and skilled operators. Our CNC lathes can handle parts up to φ400mm in diameter and 1000mm in length. We have rich experience in large diameter CNC turning. We have processed large flanges, heavy equipment sleeves, and large hydraulic cylinders. The main challenges with large parts are heat buildup, fast tool wear, clamping deformation, and vibration. We solve these by choosing the right tool geometry and optimizing cutting parameters. For product, our team designs a special clamping plan and cutting program for each type of part. This ensures the process is stable and reliable.

Accuracy is very important for large parts. A small temperature change can cause a big size change. In large diameter CNC turning, we control cutting temperatures carefully. We use plenty of coolant for forced cooling. Before final finishing, we allow enough cooling time for the part to reach a stable temperature. Our inspection tools include outside micrometers, inside dial gauges, and height gauges. These measure large diameters and geometric tolerances accurately. Over the past three years, we have completed over 500,000 product parts. Our clients are in heavy machinery, hydraulic equipment, wind power, and shipbuilding. Large parts are expensive to make. We understand you want a high first-pass yield. That is why we strictly follow our process rules for every product part.

We provide custom services for large diameter CNC turning. Large parts are heavy and have special size needs. We have designed many clamping methods to suit different workpieces.
