[Processing Example] Crankshaft 5 for S43C Engine

[Processing Example] Crankshaft 5 for S43C Engine

For small outdoor work machinery! Examples of various processes applied after rough material shaping through cold forging.

We would like to introduce a case of machining crankshafts for agricultural machinery at our company. This product is a mechanism that converts the up-and-down motion of the piston inside the engine into rotational motion. The power is transmitted to the transmission through the connecting rod and flywheel, causing the wheels to rotate. Our company is capable of building dedicated lines using gantry loaders, allowing us to excel in mass production of tens of thousands of shafts per month tailored to our customers' needs. [Case Overview] ■ Product Classification: Crankshaft ■ Delivery Industry: Outdoor Machinery Manufacturers ■ Application: Small Outdoor Machinery ■ Material: S43C ■ Size: L47mm (Flange: φ45mm) × φ10 *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Crankshaft 5 for Engine Made of SCM415

[Processing Example] Crankshaft 5 for Engine Made of SCM415

From rough processing to rolling, heat treatment, and finishing! We specialize in consistent mass production processing of shafts.

We would like to introduce a case of processing crankshafts for agricultural machinery at our company. The size is L66×φ12×φ10, with a flange diameter of φ55. The material is chromium-molybdenum steel SCM415. After machining the center hole, rough machining of the outer diameter and threading is performed on a lathe, followed by heat treatment. After that, finishing of the outer diameter and pin hole is done, resulting in the completed product. 【Case Overview】 ■Product Classification: Crankshaft ■Delivery Industry: Outdoor Machinery Manufacturer ■Application: Small Outdoor Machinery ■Material: SCM415 ■Size: L66mm (flange part: φ55mm) × φ12 × φ10 *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Crankshaft 6 for Engine Made of SCM415

[Processing Example] Crankshaft 6 for Engine Made of SCM415

High strength and wear resistance required! A case study of processing that achieved high toughness through tempering.

We would like to introduce a case study of processing crankshafts for agricultural machinery engines at our company. In the heat treatment of the shafts, we first perform carburizing and high-frequency quenching. By heating the workpiece to a high temperature and then rapidly cooling it, we can increase its hardness. While quenching increases hardness, it also has the disadvantage of making the material brittle. Therefore, we perform tempering to enhance toughness (ductility). By heating the workpiece at a temperature lower than the quenching temperature and holding it for a certain period before slowly cooling it, we can achieve high toughness. 【Case Overview】 ■ Product Category: Crankshaft ■ Delivery Industry: Outdoor Machinery Manufacturer ■ Application: Small Outdoor Machinery ■ Material: SCM415 ■ Size: L66mm (Flange: φ55mm) × φ12 × φ10 *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Crankshaft for Engine (Carbon Steel for Mechanical Structures) 3

[Processing Example] Crankshaft for Engine (Carbon Steel for Mechanical Structures) 3

Rich experience in mass production processing of shafts for automobiles and agricultural machinery! Examples of processing using hot forging.

We would like to introduce a case of processing crankshafts for agricultural machinery engines at our company. The material used is alloy steel for mechanical structures, with dimensions of L57×φ15 and a flange diameter of φ64. The rough material is shaped through hot forging, followed by center hole processing. The outer diameter is then roughly machined on a lathe, and pin holes are drilled and threads are rolled before heat treatment is performed to enhance strength and hardness. Finally, the crankshaft is completed through grinding and finishing of the outer diameter and pin holes. 【Case Overview】 ■ Product Classification: Crankshaft ■ Delivery Industry: Outdoor machinery manufacturers ■ Application: Small outdoor machinery ■ Material: Alloy steel for mechanical structures ■ Size: L57mm (flange: φ64mm) × φ15 *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Crankshaft for Engine Made of SCM415 10

[Processing Example] Crankshaft for Engine Made of SCM415 10

For small outdoor work machinery! A machining example of a crankshaft made from SCM415, a chromium-molybdenum steel.

We would like to introduce a case of processing crankshafts for agricultural machinery at our company. After forming the rough material and machining the center hole through cold forging, we performed rough machining of the outer diameter on a lathe, followed by drilling and keyway processing on a machining center. We requested a specialized heat treatment partner to improve strength and hardness through carburizing and high-frequency hardening of the threaded areas. The finished product is completed with grinding of the outer diameter and pin holes, as well as chamfering of the keyway. 【Case Overview】 ■ Product Classification: Crankshaft ■ Delivery Industry: Outdoor machinery manufacturers ■ Application: Small outdoor machinery ■ Material: SCM415 ■ Size: L50mm (Flange part: φ47mm) × φ12 × φ10 *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Crankshaft for Engine Made of SCM415 11

[Processing Example] Crankshaft for Engine Made of SCM415 11

For small outdoor work machinery! A case where toughness (resilience) was enhanced through high-frequency tempering.

We would like to introduce a case study of machining crankshafts for agricultural machinery at our company. After performing center hole processing for lathe machining, we carried out outer diameter turning, threading, and drilling on the shaft section. We requested a specialized partner company for heat treatment, which hardens the surface. At this time, if the heat treatment penetrates too much into the threaded section, it can become brittle, which is critical for shafts that require toughness. Therefore, we enhance toughness (ductility) through high-frequency tempering. 【Case Overview】 ■ Product Classification: Crankshaft ■ Delivery Industry: Outdoor machinery manufacturers ■ Application: Small outdoor machinery ■ Material: SCM415 ■ Size: L65mm (Flange part: φ53mm) × φ15 × φ10 *For more details, please refer to the PDF document or feel free to contact us.
