2K6413 Pin Caterpillar 9J6586 Ripper Shank

The 2K6413 pin is a key part that connects the 9J6586 ripper shank and the toolbar, ensuring the stability and reliability of the ripper shank during operation. The pin is made of high-quality alloy steel, and has undergone precision heat treatment and nitriding surface strengthening, which has excellent strength and wear resistance. It is a non-original part and can be matched with the Caterpillar 9J6586 ripper shank.

2. CNC machining

Parts are processed by CNC lathes and milling machines for rough and fine machining. High-precision cutting, milling and drilling are achieved through CAD/CAM programming. The machining tolerance can be controlled within ±0.01 mm

1. Turning and milling

First, the outer circle is rough turned, and then the end face and groove structure are completed by multi-axis milling tools. Finally, deburring and fine grinding are performed to ensure that the pin surface is smooth and flat.

1. Material selection

42CrMo or SCM415 alloy structural steel is selected to ensure high strength and good toughness.

2. Forging and cutting

Use precision forging or cutting machine tools to obtain nearly formed blanks to reduce the amount of subsequent cutting.

3. Heat treatment

Perform quenching and tempering treatment on the blanks (850 °C quenching + 550 °C tempering) to optimize the structure and improve the matrix strength

4. CNC machining

Complete rough machining, semi-finishing and finishing in sequence, using carbide tools and high-pressure cooling to ensure dimensional accuracy and surface quality
