Name: Chrome Plated Hard Shaft and Quenched and Tempered Chrome Plated Rod

Introduction: The chrome-plated hard shaft is processed by rough stock, peeling or cold drawing, rough calibration, high frequency quenching, fine calibration, high-tight centerless grinder, electroplating, polishing and highly professional to technical processing. The quenched and tempered chrome rod is made of quenched and tempered material through the similar manufacturing process mentioned above. The hardness and performance of hard shaft and quenched and tempered chrome-plated rod are better than that of standard chrome-plated rod. The hardness of ordinary optical axis is below 20 degrees, and the surface hardness of high frequency hardened optical axis is 58-62 degrees. The hardness of the quenched and tempered chrome rod is between 22 degrees and 28 degrees. The wear resistance and corrosion resistance of the product promote the high precision, high speed, high competitiveness and durability of the whole machine, and greatly improve the performance of the equipment.

Product use: The above products are widely used in shafts for linear bearings, special cylinder piston rods, rubber and plastic machinery, air hydraulic machinery, construction machinery, packaging and printing machinery, food machinery, medical machinery, light source machinery, textile machinery, etc. automation equipment.
