1045 CK45 S45C GCr15 4140 Chrome Plated Hard Shafts
Features
Chrome Plated Hard Shafts are manufactured using precision cold drawing bar or hot rolled bar, precision grinding, hard chrome plating and high-precision polishing processes , and all indicators meet the standard. It provides precision piston rods, guide shafts, guide pillars, guide rods, and finished shaft products for hydraulic pneumatic, textile, printing, light industry packaging, plastic machinery and other mechanical industries. Our main products include piston rods, hollow shafts, optical shafts, grinding rods, high-frequency quenching shafts, screw shafts, etc.
The optical axis is divided into hard axis and soft axis. Chrome plated hard shafts are belong to hard axis.
In precision optical shafts, there are usually requirements for surface hardness. The purpose of external surface hardness is to improve wear resistance. For metal materials, the harder the hardness, the more wear-resistant it is. However, the harder the core, the lower the toughness, and the lower the load-bearing and impact resistance. Therefore, for important shaft requirements: external hardness and internal toughness.
