The CV Joint is a crucial component of an automobile’s transmission system, directly influencing power transmission, handling, and driving smoothness. High precision and minimal tolerance are required for its various parts to function seamlessly.
The CV Joint operates in a harsh environment, enduring complex alternating loads.To ensure reliability, durability, and sufficient toughness, it undergoes heat treatment, resulting in high hardness and challenging machinability.
With extensive experience in solving customer problems and advanced R&D capabilities, MoreSuperHard has developed CBN inserts specifically for CV Joint processing. These inserts significantly enhance production efficiency and reduce manufacturing costs.
Case Study: Customer Inquiry from Thailand
Project Overview
A customer in Thailand approached us with specific requirements for processing CV Joints made of S53C medium carbon steel. Below are the key parameters:
- Tool Holder: DCLNR202K12
- Insert Type: CNGA120412 with four cutting edges
- Workpiece Material: S53C (Hardness: 60-63 HRC)
- Surface Finish Requirement: Rz ≤ 3.2
- Machining Length: 18 mm
- Turning Process Details:
Before Hardening: Diameter 46 mm (Tolerance: 0, -0.1 mm)
After Induction Hardening: Diameter 45.9 mm
Turning No.1 and Turning No.2 processes utilized the same tool holder and insert, eliminating the need for tool changes.
