[Processing Example] Crankshaft 6 for S43C Engine

Rough machining of the outer diameter is performed using a lathe! Polishing is applied to the shaft section and pin holes to complete the process.

We would like to introduce a case study of processing crankshafts for agricultural machinery at our company. The size is L48×φ12, with a flange diameter of φ48. After cold forging to shape the rough material and heat treatment (quenching), rough machining of the outer diameter is performed on a lathe. Then, keyway and thread rolling processes are carried out, followed by polishing of the shaft section and pin holes to complete the product. Our company possesses a wide range of equipment, including NC lathes and machining centers, as well as our own manufactured rolling machines and hob machines, allowing us to excel not only in turning and milling but also in gear cutting and thread rolling.

[Processing Example] Crankshaft for S43C Engine 7

[Processing Example] Crankshaft for S43C Engine 7

Introducing examples of rough material shaping and heat treatment (quenching and tempering) using cold forging!

We would like to introduce a case of processing crankshafts for agricultural machinery at our company. After forming the rough material through cold forging and applying heat treatment (quenching and tempering), we perform rough machining of the outer diameter using a lathe. Key grooves and thread rolling are carried out, and the shaft section and pin holes are finished with polishing. The tempering process, one of the heat treatments, involves reheating to over 550°C after quenching, which forms a sorbite structure and achieves high toughness (ductility). 【Case Overview】 ■ Product Classification: Crankshaft ■ Delivery Industry: Outdoor machinery manufacturers ■ Application: Small outdoor machinery ■ Material: S43C ■ Size: L62mm (flange part: φ48mm) × φ12 *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Crankshaft 8 for Engine Made of SCM415

[Processing Example] Crankshaft 8 for Engine Made of SCM415

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.

Stabilization of material components in wire spheroidization treatment.

Stabilization of material components in wire spheroidization treatment.

The automatic control of the feeder appropriately manages the input amount and input speed!

We would like to introduce the stabilization of material composition in our casting process known as "wire spheroidization treatment." When molten metal is received from the electric furnace into the ladle, the weight and temperature are input into the control computer, allowing for the subsequent addition of wire-shaped material while considering the target temperature and weight. At that time, the wire is mechanically controlled and fed from a dedicated feeder, which eliminates variations between production batches and human-induced variations, resulting in stable quality. [Wire Spheroidization Treatment] - Automatic control of the feeder allows for appropriate management of the amount and speed of addition. - Reduces the impact of human-induced variations. - Localized dust collection contributes to the improvement of the working environment. *For more details, please refer to the PDF document or feel free to contact us.
