The BMS250 blade sharpener is designed for sawyers who require a high-quality, automatic sharpening solution capable of maintaining blades regularly and reliably in a professional timber cutting business. It provides controlled, repeatable sharpening cycles to ensure consistent tooth geometry and optimal cutting performance.

Automatic Sharpening with Precise Control

The BMS250 automatically sharpens blades according to a preset number of teeth, ensuring uniform sharpening across the entire blade length. The tooth indexing system advances the blade accurately, while the adjustable tooth pusher allows fine-tuning to match blade condition and profile requirements.

The machine uses 5" (127 mm) full-profile CBN grinding wheels, available in multiple profiles to match specific blade tooth geometries. The wheels are supplied ready for use and require no dressing prior to operation. Accurate profile matching is critical for maintaining the original blade geometry and avoiding deformation or excessive stress on the blade body.

Grinding System and Motor Configuration

The BMS250 is equipped with a 0.37 kW (1/2 HP) single-phase AC motor operating at approximately 2800 rpm, providing stable and consistent grinding performance. The grinding head is factory-set at a fixed angle to ensure repeatable alignment between the CBN wheel and blade tooth profile.

An integrated oil lubrication system not only delivers mineral grinding oil to the grinding zone, reducing heat buildup and preventing thermal damage to the blade teeth, but also cleans the grinding wheel. Oil wiper pads automatically remove excess oil from the blade after sharpening. Magnets located within the oil reservoir attract and retain metal filings, allowing the oil to remain clean for reuse and extending service intervals.

The heavy-duty hood fully encloses the blade during operation, increasing safety and containing grinding debris. An integrated exhaust vent allows connection to ventilation systems to remove grinding fumes from the working environment.

Operator Control Panel

Electrical controls are positioned on the operator’s panel for straightforward access and include grinder motor on/off switch, blade drive motor on/off switch, feed rate control dial (variable speed adjustment) and the main power switch with emergency shut-off device. The variable feed rate enables the operator to adjust grinding speed depending on blade condition and steel type. An automatic shut-off function stops the sharpening cycle once the preset number of teeth has been completed.

CBN Grinding Technology

The BMS250 operates with full-profile CBN grinding wheels. CBN (Cubic Boron Nitride) is a superabrasive material offering high wear resistance and profile stability compared to conventional grinding wheels. Because the wheel profile must correspond exactly to the blade tooth design, each blade profile requires a dedicated CBN profile.

When operated with properly matched wheels and appropriate mineral grinding oil (ACP-1 or ACP-2 specification), the system ensures consistent sharpening results, controlled heat generation, and extended grinding wheel life.

The BMS250 provides a controlled, automated solution for maintaining bandsaw blades to precise technical standards required in professional sawmilling operations.
