Horizontal Type Shaft Polishing Machine

We provide the best quality automatic crankshaft polishing machines in the market. They work efficiently and are a great choice for automobile manufacturers. The machine is capable of high-quality deburring to smoothen surface roughness.

Automatic Crankshaft Polishing Machine

The automatic surface finishing machine from Inovatec is a one-stop system for auto parts manufacturers. A conveying line, a loading line, an abrasive lifting device, etc. are integrated into the machine. There is a dedicated water circulation system to keep the parts nice and clean.


  • Conveying line for the parts
  • Loading dock for the part
  • Lifting device of abrasive manner
  • Water circulation system for maximum efficiency
  • Abrasive online cleaning


  • Polishing and deburring are done on a 2-axis action
  • Up to 2 shafts processing at once
  • Improved surface hardness and wear resistance
  • Improved surface smoothness

It can be applied to all kinds of shafts, poles, covers, and parts of surface treatment. It can do polishing, grinding, rounding, and deburring without changing parts’ original size and surface roughness. It can also improve parts’ surface physical-mechanical performance. It removes surface remaining tensile stress and improves surface wear resistance and hardness.

The principle of operation:

During operation, parts are fixed in the main axis and drive up/down by a lifting device. When parts merge into a tank full of grinding media, parts rotate along their own axis and the media tank moves back and forth, thus achieving high-efficiency micro-cutting. Also, by adjusting rotary/linear movement speed, parts with different material/geometry may be achieved with optimal finishing quality.
