Parulski's invention is designed to utilize a grinder's existing rate of rotation to accelerate that rate and convert the machine to a high-speed grinder. By utilizing a specially designed pulley configuration, Parulski's invention reduces the diameter of the grinder wheel and increases the rate of travel by up to four times its original rate. High-speed grinders are expensive.
Standard grinders are more affordable, but are limited in their versatility due to slower speeds.
Other attachments of this nature lack the rigidity of this design. This attachment represents an effective, low-cost alternative for Channellock to utilize in its cutter grinding processes. The design, product development and patent-seeking process took over two years to complete, according to Parulski. The patent application was filed in July of 1998, but the design process began months before that. The patent was granted on April 25, 2000.
