How to process the cylinder guide hole?

The guide hole of standard cylinder is usually processed by single edge reamer. This kind of reamer is equipped with two guide bars, which can play a guiding role in the cutting process, but it has low sensitivity to uneven machining allowance. In addition, boring cutter is also used to process the guide pipe hole of cylinder, which is very similar to reamer. It uses three guide bars. After cutting into the workpiece, one of the guide bars immediately plays a supporting role, which improves the rigidity of the boring tool.

In the mass production of cylinder, one side and two pins are usually used for positioning. At the same time, the positioning accuracy of guide bottom hole and valve seat bottom hole is improved, the positioning error is reduced, the machining allowance is uniform, and the product accuracy requirements are ensured.

In addition, the coolant used in the production process can be divided into high-pressure and low-pressure. High pressure coolant is mainly used for processing cooling, and low-pressure coolant is mainly used for chip cleaning. This kind of classification can make the process of the guide hole of the cylinder better.
