4.0Machine and Manual Overview

JET Abrasive Finishing Machines are available in three different configurations: disc, belt, and combination disc and belt. Each configuration is a rugged, heavy-duty machine designed for maximum high production work in an industrial environment.

The speed of stock removal and the quality of finish achieved is determined largely by the aggressiveness of the abrasive disc or belt mounted on the machine. With very aggressive grits, these machines are typically considered grinding machines. With very fine grits, these machines are typically considered sanding machines. Whatever you call them, and however you use them, the instructions in this manual will help you use them safely and productively.

You will note there are several types of electrical systems available for these machines. All of these systems are equally effective in providing power to the grinding mechanism – however, local codes and the type of environment in which the machine is used will often be a factor in your choice of system.

Instructions in this manual assume that you are using one of the Model J-4200A Series Belt and Disc machines. If you have a disc only, or belt only machine, you can bypass those instructions which do not apply to you.

If there are questions or comments, please contact your local supplier or Walter Meier. Walter Meier can also be reached at our web site: www.waltermeier.com.
