Salem’s GTX series consists of roughing, finishing and polishing wheels.

WINSTON-SALEM, N.C.—Salem Vision Group, based here, is releasing the GTX series of high-performance edging wheels. The series consists of GTX-R roughing, GTX finishing and GTX polishing wheels. The wheels incorporate the latest diamond bonding technologies to produce a dramatic increase in the overall performance and cost-efficiency of plastic lens edging, from roughing to finishing to the final polish, regardless of the lens material, according to Salem.

The GTX-R roughing wheel features a brazed single-layer diamond bond. This configuration optimizes diamond exposure and concentration to produce faster, cooler, cleaner cuts and to virtually eliminate wheel loading even with polycarbonate and Trivex lens materials. The GTX-R roughing wheel also features a surface coating that reduces torque during edging to maintain accurate axis alignment.

“The GTX finishing and polishing wheels feature specifically formulated metal bonds. Each bond formulation is blended throughout with precisely graded diamond particles to optimize its specific application: finishing or polishing. The GTX finishing and polishing wheels contain the perfect combination of diamond size, concentration and bond hardness to produce fast, smooth, chip-free edges job after job,” according to the company.

GTX edging wheels can be used on all plastic lens materials including polycarbonate and Trivex and are available for all major brands of edgers. ■
