Specialized Rail Grinding Wheel

Basic Info

A heavy-duty grinding wheel specially designed for in-track maintenance and repair of railway rails. Used to grind the rail head and side for corrugation (roaring rails), shelling, lip formation, and weld joint irregularities, restoring track smoothness, extending rail life, and reducing train noise.

Customer reviews

Elena Rodríguez · Toolroom Manager

We purchased your white aluminum oxide precision wheels for our HSS tool sharpening. The results are outstanding, achieving excellent edge finish and straightness that fully meets precision tool requirements. More importantly, your technical team provided highly professional selection advice, recommending the most suitable grit and hardness combination based on our equipment and material, avoiding common burning issues. Professional products coupled with professional service.

Marcus Weber · Production Manager

For the past six months, our workshop has fully switched to your company's CBN superabrasive wheels for camshaft finish grinding. The most immediate change was a reduction in single-part processing time by approximately 15%, and the wheel has not required dressing yet, with excellent dimensional consistency. Sparks in the grinding zone are noticeably reduced, indicating lower thermal impact on the workpiece. Overall calculation shows that despite the higher initial investment, the cost per part has actually decreased. A truly efficient and long-lasting tool.

Lucas Miller · Production Supervisor

Your grinding wheels deliver stable hardness—we use brown alumina models for carbon steel grinding, no workpiece burn or vibration issues. The wear resistance is better than our previous supplier, cutting our replacement frequency by 20%. Worth the investment.

Product Description

Product Features:

Extremely high mechanical strength, impact toughness, and heat resistance to withstand the high pressure and power from large rail grinders or grinding trains. Special bond formulations ensure it does not fail or wear excessively under the恶劣 conditions of dry or minimal-water-cooled grinding. Very high grinding efficiency.

Product Specifications:

Usually large diameter (200-300mm) straight or cup wheels. Abrasive is typically high-performance, high-toughness brown aluminum oxide or sintered alumina. Very coarse grits (16-30). Very hard grades (R to V) to resist severe rail abrasion. Safe operating speeds can reach 63-80 meters per second.

Product Applications:

A core maintenance consumable for railway track departments. Used to repair periodic corrugation on the rail head; remove side lip (gauge corner); grind flash-butt or thermite welds flush with the parent rail; perform preventive grinding to optimize wheel-rail contact and prevent defect initiation.
