Product Info
The RazorGage ST automatic positioner system features a high-performance motion controller that reacts quickly to jambs, eliminating stretched belts. Hence, the 5 year belt warranty.

The carriage assembly features a Hiwin hardened and ground linear bearing rail with two recirculating ball bearing blocks — just like you see on CNC machine tools and machining centers. This enables nearly friction-free motion, maximum rigidity, accuracy and long life. The RazorGage ST can be used for automatic chop saw measuring, or it may be installed for use alongside other types of saws.

If you’re investing in an automatic saw measuring system, you want a product that is dependable every single day. Replacing parts and paying for repairs will cut into your ROI. To get the most out of your new programmable saw positioner, choose one with superior components made of high-quality materials.

For example, the positioning carriage on a RazorGage automatic saw system is mounted on recirculating ball bearing blocks rolling on hardened steel. Competitors use plastic and aluminum — materials that are much more prone to inaccuracy and wear. RazorGage components are designed to minimize backlash, reduce wear and ensure a high level of accuracy and consistent performance time after time. By comparison, our competitors’ components are lower quality, and it shows in the overall poorer performance of the positioner.

1. RazorGage: Positioning carriage mounts on two re-circulating ball bearing blocks sliding on a hardened & ground steel rail. Just like you see on CNC machining centers!1. Competitor: Uses plastic strips sliding on aluminum as the positioning carriage bearing.
2. RazorGage: Electronics are sealed inside IP54 rated housing impervious to chips.2. Competitor: Electronics sensitive to chips are inadequately protected.
3. RazorGage: Utilizes a planetary gear-head with 3 load paths transmitting torque & less than 7 arc minutes of backlash to maximize accuracy.3. Competitor: Spur gear style reducer others use, with 1.2 gear teeth transmitting load, is prone to excessive backlash.
4. RazorGage: Uses no sensors for homing or end of travel eliminating the need for failure prone components and wiring.4. Competitor: Contamination sensitive sensors inside the beam require long cable runs around sharp corners.
5. RazorGage: 30 tooth drive pulley used on RazorGage has a larger bend radius increases belt life and twice the teeth to resist tooth shear.5. Competitor: 15 tooth pulley competitor uses, has a tighter bend radius reducing belt life and half the teeth to resist tooth shear.
6. RazorGage: The RazorGage drive pulley is machined to match the belt tooth profile eliminating backlash.6. Competitor: Standard pulleys have 1/64” clearance allowing backlash which reduces accuracy.
