CD Centrifugal Disk Finishing Machines with Manual Discharge

If you’re in need of an economic solution to finish your small parts, the Centrifugal disc finishing machine from Inovatec is a prime choice.

We call it the economic model because it has a manual discharge instead of an automatic one.

Disc finishing machines operate almost 10 times faster than vibratory machines and it’s one of the major selling points for CD finishing machines.


Centrifugal Disc Finishing Machine Product Description

Centrifugal disc finishing machines are designed for high-speed operations with minimal cost.

It works much faster than vibratory finishing machines and results in a shorter cycle and higher automation.

The Centrifugal Disc finishing machine from Inovatec comes in 50L, 80L, and 120L variants. At least they are the most famous ones. You can get your own made as well according to your needs.

These machines operate from 50 RPM to 180 RPM. Different RPM settings result in different surface finishes.

You can get an optional processing barrel as well for discharging parts.



  • Compact and lightweight design
  • User-friendly
  • Timer for controlling processing time
  • Continuous speed adjustments



  • Casting, machined parts and stampings processing
  • Parts with a size not bigger than 200 mm and no thicker than 1mm

Adjusting method

After removing the locking bolt and the central cover, adjust part 1 (adjusting screw):

to reduce the clearance, screw part 1 clockwise, it moves down, which will cause parts 2 and 4 to move up.

If there is no clearance at the pitching-in between part 1 and part 2, put a steel washer on the top of part 3, the spindle, and then start adjusting (the inner diameter of the washer must be smaller than the diameter of the spindle).

Introduction for centrifugal disk finishing equipment

Inovatec centrifugal disc finishing machines provide 10 times the effective faster-grinding speed compared with conventional vibratory finishing machine.

Centrifugal disc finishing machines are typically in small to medium size component surface finishing application.

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

2. Disc rotating system

  • High-speed control with optional speed inverter from Bosch Rexroth
  • Adjustable gap between disc and ring

3. Water process system

  • Compound/water dosing system available with tap
  • PLC touch screen control with Siemens optional

4. Rigid machine construction


Working principle for centrifugal disk tumbler

The rotating disc with speed 60-250 RPM pushes the tumbler 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 offers productivity 10-30 times higher compared with the conventional vibratory finishing process.


Centrifugal Disk Finishing Machine Application

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 a combination of different other finishing technology according to user requirement.
