Product descripation:
Brief Introduction to Equipment Performance:
This machine is mainly used for polishing the outer circle of piston rod before and after plating. The polishing method is through dry casting.
The machine is composed of a bed, a polishing head, a workpiece conveying device, a workpiece automatic feeding frame, a workpiece automatic feeding device and a feeding frame.It has the characteristics of high automation, high efficiency and high machining precision. After polishing, the roughness can reach Ra0.2.
2. Main Parameters:
Ø III)specification & composition
3. Main parameter:
1. processing outer diameter range:Ø60- Ø130mm
2. processing length range: 750-2500mm
3. the Ra value after processing:Ra≤0.2
4. the outer diameter tolerance after polishing: IT8
4、Material requirements before polishing:
The initial state of the piston rod is the finished surface of the outer circle by centerless cylindrical grinding, The outer diameter tolerance is IT8(For example the diameter tolerance is k8), roundness<0.005mm,cylindricity<0.025mm/1000mm;, Roughness of outer surface <Ra1.0um.
