Quality Assurance

All custom grinding wheels are manufactured under a strictly enforced quality control system and ultimately certified by MPA, ensuring full compliance with international safety and performance standards.

Q: What is a grinding wheel?

A: A grinding wheel (also called a polishing disc) is a disc-shaped grinding tool that is made of sharp abrasive particles bonded by a resin binder. Qing Yang uses a variety of abrasive formulas according to different operating scenarios, and all products are compatible with standard angle grinder interfaces. The reinforced grinding wheel embeds multiple layers of high-strength fiberglass mesh in the resin layer, which can increase the service life by 50% and ensure structural stability under extreme working conditions.

Q: What are the main uses of grinding wheels?

A: The core functions cover five major areas:

1. Metal surface treatment (rust removal/weld scar cleaning)

2. Industrial burr removal

3. Automotive sheet metal repair

4. Concrete substrate pretreatment

5. Rapid material removal (such as steel structure cutting)

Innovative application: Our 1/8 inch (about 3.2mm) hybrid grinding disc can complete cutting and rough grinding at the same time, reducing tool replacement time by 70% in steel bar/metal pipe operations.

Model and technical parameters

Q: What is the difference between T1 and T27 grinding wheels? ​

Q: How to choose abrasive materials?

A: Recommended solutions based on metal characteristics:

• ​​Aluminum oxide​​: Black metals such as carbon steel/stainless steel (resistant to high temperature sintering)

• ​​Silicon carbide composite formula​​: Dedicated for soft metals such as aluminum/copper (patented anti-blocking technology)

Technical breakthrough: Qing Yang soft metal grinding wheel adopts low-temperature grinding process, which can reduce the temperature rise of the workpiece by 65% through pressure sensor control.

Safety Operation Guide

Q: Can grinding wheels and cutting discs be used together?

A: Absolutely prohibited! The essential differences are as follows:

Q: What are the iron rules for safe operation?

A: 10 major guidelines must be followed:

1. Triple protection: mask + anti-cut gloves + noise-reducing earmuffs

2. Pre-start inspection: Cracked/defective grinding wheels must be scrapped immediately

3. Power matching: angle grinder rated power ≥ grinding wheel requirements

4. Protective cover disabled: It is strictly forbidden to remove or modify protective devices

5. Speed control: equipment no-load speed ≤ grinding wheel red line mark

6. Start-stop specification: start idling for 30 seconds → operation → complete stop before leaving

7. Operating posture: hold with both hands + stable standing posture

8. Dress requirements: tight work clothes + hair tie (to prevent entanglement)

9. Regular maintenance: check the status of the motor carbon brush every shift

10. Emergency preparation: configure fire extinguishing equipment within the operating radius of 3 meters
