Angle Grinding Machine

BOSI's Angle Grinding Machine series covers a variety of power and wheel sizes to meet different needs from fine grinding to heavy-duty cutting. The entire series uses high-quality bearings (some models use imported NSK, NMB, TPI) for durability; the wear-resistant and shock-resistant housing combined with a non-slip handle provides a comfortable grip and is suitable for construction environments. Power ratings include 720W, 880W, 1100W, 1600W, and 10A (approximately 2200W and above), with wheel diameters of 100mm, 150mm, 180mm, and 230mm.

Suitable for casting grinding, shipbuilding rust removal, metal polishing, stone cutting, and other operations. Some models are positioned as "Grinding King," "Cutting King," or "Grinding and Cutting Pioneer," allowing users to choose according to their working conditions.

Product Specifications

Note: 10A is approximately 2200W based on 220V; actual output power may be higher. The maximum overload capacity of 3800W is a short-term peak value.

Model Selection Suggestions

By grinding wheel diameter: 100mm is suitable for fine grinding, polishing, and thin plate cutting; 150mm has better versatility; 180mm/230mm are used for heavy-duty cutting and thick plate grooving.

By power: 720W-880W is suitable for home DIY and light grinding; 1100W is suitable for professional maintenance and medium load; 1600W is suitable for high-intensity continuous operation; 10A (2200W) is used for heavy cutting and shipbuilding rust removal.

By speed: High speed (11000-12000r/min) is suitable for grinding and polishing; medium speed (8000-9000r/min) is suitable for cutting; low speed (6000r/min) is suitable for cutting thick metal with large-diameter grinding wheels.

By Switch Type: Rear switch is suitable for users accustomed to operating from the rear; side switch (side opening) operation is faster.

By Series Positioning: "Grinding King" focuses on grinding and polishing; "Cutting King" focuses on cutting; "Grinding and Cutting Pioneer" is balanced; "Slim Waist" has a slender body and is comfortable to hold.

Product Advantages

Imported high-quality bearings: Some models of our Angle Grinding Machine use NSK, NMB, and TPI bearings, which are wear-resistant and high-temperature resistant, resulting in a longer machine lifespan.

Wear-resistant and Drop-resistant Housing: Thickened engineering plastic, resistant to drop impact, suitable for complex construction site environments.

Anti-slip handle: Rubber-coated or specially textured design, provides a stable grip even with wet or oily hands.

Efficient heat dissipation: Optimized airflow design prevents overheating during prolonged operation.

High-power motor: Pure copper windings provide strong power, ensuring worry-free operation under heavy loads.

Overload capacity: The 180mm/230mm models have a maximum overload capacity of 3800W, capable of handling hard materials for short periods.

FAQ

Q: Is it normal for an angle grinder to produce a lot of sparks during operation?

A: Normal sparks when using a new grinding wheel or cutting thick metal. If the sparks are abnormally large and accompanied by noise, check if the carbon brushes are worn, if the grinding wheel is broken, or if it is misaligned.

Q: Can grinding wheels of different diameters be interchanged?

A: No. A grinding wheel with the same diameter as the machine must be used; otherwise, mismatched speed may cause it to break and cause injury.

Q: How to determine if a bearing is damaged?

A: If the machine makes abnormal noises (rustling or sharp friction sounds) while running, and there is a feeling of sticking when manually turning the grinding wheel after stopping the machine, the bearing needs to be replaced.

Q: How often should carbon brushes be replaced?

A: Generally, check every 50-100 hours of use. Replace the carbon brushes when they are worn down to 1/3 of their original length. It is recommended to use original carbon brushes.

Q: What should I do if the Angle Grinding Machine vibrates severely during cutting?

A: Check if the grinding wheel is unevenly worn or eccentric; check if the flange is locked; check if the spindle is bent. If the shaking persists after troubleshooting, send it for repair.
