Hydraulic Cylinder Components
This project involved the precision machining of hydraulic cylinder components for a leading heavy equipment manufacturer. The components were designed for demanding hydraulic applications where dimensional accuracy, mechanical strength, and wear resistance are critical to long-term operational performance.
Manufactured from premium 4140 alloy steel, each component underwent advanced CNC turning and multi-axis milling, followed by induction hardening to improve surface hardness and extend service life. Every finished part was subjected to comprehensive dimensional verification using Coordinate Measuring Machine (CMM) technology to ensure full compliance with customer engineering specifications.
