19、device that will automatically adjust the stone feed mechanism to compensate for abrasive wear. 3.2.7.1 Spark-out control. If required, the machine shall have a control for stopping expansion of the honing stones while rotation and stroke are continued so that the stones can clean the bore as specif

20、ied (see 7.3(g). The control shall aiiow the time or number of spark-out strokes to be preselected. The control shall be mounted on the operators control panel. 3.2.7.2 Stone wear indicator. The machine shall have a stone wear indicator that warns the operator by light, bell, or buzzer when the ston

21、es are worn to the extent that workpiece damage is imminent. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-II 9038054 0005503 Y48 I A- A- 59394 3.2.8 Guide bushing bracket.
