Centrifugal Finishing Machines

Gala Precision Engineering Private Limited offers a Centrifugal Finishing Machine composed of number of barrels mounted on the periphery of turret. The turret rotates at high speed (RPM) in one direction while the barrels are rotated in the opposite direction. Parts to be deburred and finished are placed in each of the barrels, normally together with media, water and some form of compound. Turret rotation creates a high centrifugal force of up to 50 times earth gravity, thus compacting the load within the drums into a tight mass. The counter rotation of the barrel causes activity of this tightly packed mass. The media slides against the parts being processed, removing burrs and improving surfaces. The abrading action during the high centrifugal force results in a very short process cycle. The inclined axis barrel rotation generates unique super-eight motions, which causes additional rubbing and polishing effect.
Advantages:

• Burnishing and mirror-like finishing - the raw steel with roughness of 10 micron can be improved to 0.5 micron in 30-60 minutes, while the conventional burnishing and lustering can be obtained in 15-30 minutes
• Heavy deburring - take 20-30 minutes for major deburring, descaling of black skin of casting and forging, finishing of tiny parts
• The cutting action is similar to center less grinder
• Elimination of entanglement and distortion - no distortion found in thin plates (up to 0.4 mm thick)
• Small thin flat parts, which easily stick to each other and used to be impossible to process can be perfectly processed, e.g., valve reeds, etc.
• Consistency and uniformity - once the processing parameters are set the consisted results are obtained making this equipment suitable for mass finishing.
