Grinding, or abrasive machining, once performed on conventional milling machines, lathes and shapers, are now performed on various types of grinding machines. Grinding machines have advanced in design, construction, rigidity and application far more in the last decade than any other standard machine tool in the manufacturing industry.

7. Machine/Spindle Horsepower. The horsepower of the grinding machine can play a role in determining the grade of the bond or the hardness of the wheel. When a machine has a higher horsepower available at the spindle, harder wheel grades are wiser. The harder wheel will hold form and retain the grains as long as possible under the stronger forces.

Front-load and top-load washers will have different reasons for making grinding, humming, or squealing noises. Grinding is generally a sign that a part has worn out. Humming, on the other hand, is caused by something getting stuck or jammed. Lastly, squealing could be caused by a part like a belt that's become stretched out.

ELB-Schliff Werkzeugmaschinen has been producing surface and profile grinding machines for over 60 years.
