HXB-768-15A3 Medium Size Dry Polishing Machine for Metal Parts Finishing

Product Overview

The QISHENG HXB-768-15A3 Medium Size Dry Polishing Machine is designed for the surface finishing of metal components that require consistent polishing, deburring, and surface improvement.

Equipped with a 15kW main motor and a rotating shaft with adjustable speed from 0 to 140 r/min, this industrial dry polishing machine supports both forward and reverse rotation to accommodate different processing requirements.

One of its main features is the four-sided bucket grid system, which can be divided into a maximum of 768 individual cells. This compartmentalized structure helps separate workpieces during polishing, reducing direct contact between parts and minimizing the risk of collision marks.

With overall dimensions of 2800 × 2170 × 2277 mm, the HXB-768-15A3 offers a medium-sized solution for manufacturers looking to improve metal finishing efficiency while maintaining control over workpiece handling.

It is suitable for processing various hardware components, decorative metal parts, automotive accessories, and other precision metal products.

Key Features and Benefits

1. Up to 768 Individual Polishing Compartments

The machine uses a four-sided bucket grid structure that can be configured with up to 768 individual cells.

Unlike conventional bulk polishing methods, where multiple parts may come into direct contact, the divided compartment design allows workpieces to be processed separately.

This is particularly useful for components that require careful surface protection during finishing.

Key benefits include:

• Helps reduce workpiece-to-workpiece collisions.

• Minimizes the risk of scratches and contact marks.

• Supports more consistent surface finishing.

• Suitable for batch processing of small metal components.

2. 15kW Main Motor for Industrial Applications

The HXB-768-15A3 is equipped with a 15kW main motor designed to drive the rotating polishing mechanism.

The machine is intended for industrial metal finishing applications where consistent operation and controlled processing are important.

For manufacturers handling repeated production batches, the motor and rotating structure provide a practical solution for integrating dry polishing into the finishing process.

3. Adjustable Speed with Forward and Reverse Rotation

The main shaft supports an operating speed of 0–140 r/min and can rotate in both forward and reverse directions.

This allows operators to adjust the rotation according to the workpiece characteristics, polishing media, and desired finishing results.

The adjustable operating speed provides flexibility when handling different metal components, helping manufacturers establish suitable polishing parameters through sample testing.

4. Dry Polishing Process Without Liquid-Based Finishing

The HXB-768-15A3 uses a dry polishing process rather than a conventional liquid-based polishing method.

Depending on the workpiece material and finishing requirements, suitable dry polishing media can be selected for surface treatment.

The dry finishing process can help manufacturers reduce water consumption and avoid wastewater generated by wet polishing operations.

It can also simplify certain post-processing requirements, although final cleaning and finishing procedures depend on the workpiece and media used.

5. Medium-Sized Structure for Factory Production

With a machine footprint of approximately 2800 × 2170 mm and a height of 2277 mm, this model is designed for factories requiring a medium-sized polishing system.

Its enclosed structure separates the polishing area from the surrounding production environment, while the front access doors and external control panel support routine machine operation.

The HXB-768-15A3 is an option for manufacturers seeking compartmentalized dry finishing without moving to a larger machine model.

Technical Specifications

Applications of the HXB-768-15A3 Dry Polishing Machine

This medium-sized dry tumbling polishing machine is suitable for a variety of metal finishing applications, particularly where individual workpiece separation is important.

The suitability of individual materials, component shapes, and surface finish requirements should be verified through sample polishing tests.

How Does the Dry Polishing Machine Work?

The HXB-768-15A3 uses a rotating mechanism combined with a compartmentalized bucket grid system to process metal components with suitable dry polishing media.

Workpieces are placed inside the designated compartments, where the rotating movement promotes contact between the polishing media and the component surfaces.

The main shaft operating speed can be adjusted within the specified range of 0–140 r/min, and the machine supports forward and reverse rotation.

A typical polishing process involves the following steps:

1. Workpiece Evaluation: Identify the metal material, part dimensions, initial surface condition, and target finish.

2. Media Selection: Select suitable dry polishing media based on the workpiece and finishing requirements.

3. Compartment Loading: Place workpieces into the divided grid structure according to the selected loading arrangement.

4. Parameter Adjustment: Set an appropriate shaft speed, rotation direction, and processing duration.

5. Surface Finishing: Run the machine so that the media can act on the workpiece surfaces.

6. Result Inspection: Remove the workpieces, separate any remaining media, and inspect the finished surface.

Processing time, media quantity, loading capacity, and achievable surface roughness vary by application and should be determined through testing.
