A processing example that requires fine adjustments, such as controlling the cutting depth to prevent chipping of the blade edge!
We would like to introduce a case study of processing crankshafts for agricultural machinery at our company. Generally, lathe processing is performed with continuous cutting, but in the case of intermittent cutting, the tool is pressed against the material intermittently, making it prone to chipping and vibration, which makes it difficult to maintain stable machining accuracy. Using chips that are less likely to chip is a prerequisite, but even so, fine adjustments such as controlling the feed rate and cutting depth to prevent the cutting edge from chipping are required. 【Case Overview】 ■Product Classification: Crankshaft ■Delivery Industry: Outdoor Machinery Manufacturer ■Application: Small Outdoor Machinery ■Material: SCM415 ■Size: L65mm (Flange part: φ47mm) × φ12 × φ10 *For more details, please refer to the PDF document or feel free to contact us.
