Product Positioning

Core Sanding Belt for Standard Industrial Applications

Aluminum oxide sanding belts are general-purpose industrial belts designed for wood, carbon steel, and composite materials. They are widely used on wide belt sanders, vertical belt grinders, and edge sanding machines.

Product Overview

Stable Cutting, Predictable Wear and Long Service Life

Aluminum oxide abrasives offer stable cutting behavior and predictable wear patterns, making them highly reliable for continuous industrial sanding.
Compared to premium abrasives, aluminum oxide belts provide superior cost efficiency and process stability under medium load conditions.

Belt Backing & Machine Compatibility

Selecting Backing by Tension and Machine Type

Belt backing selection directly affects tension resistance and dimensional stability during operation and must match machine requirements.

X-weight cloth backing

Suitable for medium-tension machines such as vertical belt grinders and edge sanders.

Y-weight cloth backing

Designed for high-tension wide belt sanders with superior tensile strength.

Process Stages & Grinding Strategy

From Stock Removal to Surface Preparation

• Rough grinding: Rapid stock removal and shape establishment
• Medium grinding: Surface leveling and scratch reduction
• Fine preparation: Preparing surfaces for coating or finishing

Aluminum oxide belts effectively cover rough to medium grinding stages.

Tension, Speed & Load Control

Key Parameters for Belt Stability and Life

Belt stability is highly dependent on machine parameter settings:

• Low tension: Belt tracking issues and slippage
• Excessive tension: Increased risk of belt breakage
• High belt speed: Accelerated abrasive dulling and heat buildup
• Excessive feed pressure: Reduced belt life

Proper tension and speed balance is critical for maximizing belt service life.
