Product Overview

The vortex wet & dry dual-use precision finishing machine integrates wet grinding and dry mirror polishing into one single unit. It is professionally designed for mass precision surface finishing of small and medium-sized workpieces. Adopting high-speed vortex flow grinding technology, it efficiently completes deburring, chamfering, flash removal, mold line elimination, tool mark removal, oxide layer stripping, rust removal and mirror polishing processes.

This machine solves the common pain points of traditional vibratory finishing equipment such as workpiece stacking, uneven polishing and low efficiency. It supports rough grinding, fine polishing and high-gloss mirror finishing in one device. Widely applied in precision manufacturing industries including hardware, 3C electronics, jewelry and medical devices, it serves as a cost-effective alternative to imported finishing equipment and effectively reduces customers’ surface processing costs.

Working Principle

The bottom turntable rotates at high speed to generate strong centrifugal force, driving workpieces and media to form a spiral vortex tumbling motion inside the fixed grinding barrel. Uniform and gentle friction between workpieces and grinding media realizes precise surface finishing without damaging workpiece precision.

1.Wet Mode: Operates with water and polishing compounds, ideal for deburring, chamfering, rust removal and rough & precision grinding.

2.Dry Mode: Uses walnut shell media, corn cob media and dry polishing paste without water, achieving high-brightness mirror polishing effect.

Workpieces are fully separated during operation to avoid collision and damage. It perfectly handles inner holes, gaps and special-shaped dead corners with uniform finishing. The open-barrel design allows random workpiece sampling and quality inspection without shutdown, enabling real-time processing quality control.

Core Product Advantages

✅ 2-in-1 Wet & Dry Dual Function

Freely switch between wet grinding and dry mirror polishing. One machine covers the whole process from deburring to mirror finishing, saving equipment investment and adapting to diversified workpiece production needs.

✅ High Processing Efficiency

Vortex flow grinding greatly improves processing efficiency, 10-30 times faster than traditional vibratory finishing machines. It upgrades surface roughness by 1-2 levels in a short time, fully meeting mass production requirements of small precision parts.

✅ Precision Finishing & Zero Workpiece Damage

Workpieces tumble in a suspended vortex state to avoid collision and scratching. With precise gap control, it is suitable for tiny, thin-walled and easily deformable precision parts. It will not change the original workpiece size and tolerance, and can fully polish special-shaped structures, tiny holes and narrow gaps.

✅ Durable Structure & Low Maintenance Cost

The grinding barrel and turntable are lined with thickened wear-resistant PU polyurethane material with excellent impact and abrasion resistance. Key friction parts are equipped with high wear-resistant gaskets. The whole machine runs stably with low noise and no severe vibration, creating a friendly working environment and extending service life.

✅ Intelligent Control & Easy Operation

Equipped with variable frequency stepless speed regulation, timing processing and forward/reverse rotation functions. The adjustable speed adapts to different workpiece materials and processing techniques. No professional skills are required – operators can start automatic operation simply by feeding materials and setting parameters. One worker can manage multiple machines simultaneously. The tiltable barrel design enables convenient and labor-saving discharging.

✅ Open Barrel Sampling Design

Workpieces can be sampled and inspected at any time during operation without shutdown, allowing flexible adjustment of processing time and reducing trial-and-error costs.
