Equipment Selection Tips

Selecting equipment to grind, hone and polish can be a daunting task. There are several factors to take into consideration, among them the equipment's power requirements, weight, motor size, overall dimensional size, working dimensions and direction or directions the abrasives rotate. At this point you may be thinking, "What is so daunting? It looks pretty basic to me." There is a saying in this business, "The more you learn the more you realize how little you know."

As you read this article keep in mind it addresses common or typical machines; specific characteristics vary from one manufacturer to another. Let's examine the selection factors.

Power requirements. Equipment is either powered by cord electric, battery electric or propane,Watches Replica, and in some cases hydraulic driven motors are used. With propane power there are no cords and no electrical requirements other than the battery used for starting the machine. Electrical requirements for cord electric equipment are typically 110 volt single-phase, 220 volt single-phase or three-phase, and 460 volt three-phase. Some 220 volt pieces of equipment allow you to run them single- or three-phase. Amperage requirements can range as low as 20 amps and as high as 60 amps.

Keep in mind high motor voltage equals lower amperage requirements and smaller gauge power cord. Although, many electrical panels are thought of as 220 volt and often their true output is only 208 volts. If you plug your machine into a source that is only 208 volts make sure the equipment has the ability to run on the lower voltage. If not you will have to invest in a transformer, often referred to as a buck booster, to boost the voltage. NOTE: Always use a qualified, licensed electrician when hooking up your equipment for use.

Weight. Walk-behind equipment ranges in weight from 110 pounds to over 2,000 pounds before optional weights are applied. Ride-on equipment can weigh over 13,000 pounds. Equipment weight is important from a transportation point of view, but more important is the actual weight or head pressure over the abrasives.
