Grinding: what is, features

The rotation of Makhovichka 10 Karetka is reported by the reciprocating movement (longitudinal feed) and grind.

Grinding is performed in the following order: during preliminary grinding, an intense removal of the metal is performed; In this case, the transverse feed is carried out after each double (reciprocal) passage of abrasive circles. After the metal is removed, along the entire circumference of the neck and throughout its length, further final grinding is carried out with repeated longitudinal movement of the carriage without transverse supply, during the final grinding, individual tubercles are removed after preliminary grinding due to the uneven supply of abrasive circles and their squeezing them.

In the case of applying the abrasive circles of the E46S2K brand, when the crankshaft revolutions from 8 to 25 per minute and the diameter of the Shek from 150 to 300 mm, you can get the cleanliness of the seventh class surface. When using circles with a larger granularity that does not provide the required surface purity, after grinding, the neck can be polished with felt circles installed on the bracket instead of abrasive circles.

At the end of the processing of one neck, the machine is moved along the guides and installed above the next neck and t. D.

After the processing of all the indigenous necks that were not on the supports, specially made, narrow, babbit fed -lifted -up for processed neck, located on both sides of the necks, relying on intermediate supports and located next to these neck. The newly supplied false ladders are manufactured in advance, processing their outer supporting surface in accordance with the diameter of the bed with ensuring planting, and the inner surface of the Babbitsky allowance for subsequent final processing.

As soon as “the corresponding necks are finally processed, the inner surface of the Babbitic fill is treated in accordance with the diameter of the corresponding processed necks.
