  1. A
    14 inch\frac{1}{4}\text{ inch}
  2. 18 inch\frac{1}{8}\text{ inch}Cevap
  3. C
    12 inch\frac{1}{2}\text{ inch}
  4. D
    34 inch\frac{3}{4}\text{ inch}

Cevap

The maximum allowable clearance between the tool rest and the abrasive grinding wheel is 18 inch\frac{1}{8}\text{ inch}.
Under standard workshop and OSHA safety guidelines, the tool rest on a bench or pedestal grinder must be set to a maximum distance of 18 inch\frac{1}{8}\text{ inch} from the face of the abrasive wheel. This provides firm mechanical leverage for the operator and eliminates the risk of stock getting wedged into the rotating wheel.

Adım Adım Çözüm

1
Recall the safety standards and clearance specifications for stationary bench grinders.
The tool rest must be adjusted to within 18 inch\frac{1}{8}\text{ inch} (3.2 mm3.2\text{ mm}) of the wheel face.
Maintaining a tight 18 inch\frac{1}{8}\text{ inch} gap prevents the workpiece from catching, jamming, or slipping into the wheel housing, which could cause catastrophic wheel explosion or operator injury.
