Centrifugal disc finishing machine (automatic unloading with separator)


Humo centrifugal disc finishing machines provide 10 times effective faster grinding speed compared with conventional vibratory finishing mahcine. Centrifugal disc finishing machines are typically in small to medium size component surface finishing application.  

For special finishing requirement, the centrifugal disc finishing machine especially used for super fine and mirror finishing of specific component or component of special surface requirement

  1. Processing unit (work bowl)

The processing bowl is casted with DuPont hot moulded PU lining with thickness 20-25mm for long service time and high durability

  1. Disc rotating system

High speed control with optional speed inverter from Bosch Rexroth

Adjustable gap between disc and ring

  1. Water process system

Compound/water dosing system available with tap

PLC touch screen control with Siemens optional

  1. Rigid machine construction

Working principal

The rotating disc with speed 60-250 RPM pushes the media and components mixture upward to the wall of processing bowl and downward to the processing bowl centre. With reduced acceleration force and enhanced gravity force mixture slides back down to the disc where it is again accelerated. Depending on disc rotation speed, the water level as well as media/compound combination, the finishing applications vary from fast grinding to super fine mirror polishing.

The high energy centrifugal disc finishing machine offer an productivity 10-30 times higher compared with conventional vibratory finishing process.


The area of application including deburring, surface grinding, radiusing, and polishing of components with thickness around 0.2mm and larger gear components with more than 150mm. Typically stampings parts, casting parts as well as machined parts and tuned parts processed with high speed of the centrifugal disc finishing machine can achieve desirable performance in relative short processing times. Besides, it can achieve a high degree of automation with combination of different of other finishing technology according to user requirement.


Tilting angle of processing bowl up to 135°

Optional circular pipe to rinsing and compound dosing

Gap adjustment for machine for disc and ring

With automatic control processing bowl can be tilted mechanically with gear motor

The screens can be changed easily and not requiring special tools and devices
