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.

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.

Sophie Laurent · Senior Mold Technician

We perform polishing on high-end molds long-term, with stringent surface quality requirements. Your company's polyurethane elastic polishing wheel series was a pleasant surprise. Their hardness grading is very accurate, allowing for a smooth and efficient transition from rough to mirror polishing. The abrasive distribution is even, preventing uneven streaks on the mold surface, and the wheels themselves wear slowly with a long service life. This has become the standard configuration for our polishing process.

Product Description

Product Features:

High purity abrasive offers slightly higher hardness than brown aluminum oxide but greater friability, promoting the formation of new sharp cutting edges during grinding and reducing the risk of grinding burns. Capable of achieving superior surface quality and geometric accuracy compared to brown aluminum oxide wheels.

Product Specifications:

Typically features finer grit sizes, commonly between #80 and #220. The structure is dense with high demands on hardness uniformity. Often comes in straight, cup, or dish shapes. Requires higher dynamic and static balance standards to suit precision grinding machines.

Product Applications:

Primarily used for sharpening high-speed steel (HSS) and alloy tool steel cutting tools (e.g., milling cutters, reamers, broaches), as well as finish grinding of precision molds, gauges, and mechanical components (e.g., bearing races, machine tool guideways). Suitable for surface grinders, tool and cutter grinders, and cylindrical grinders.
