Scraping and rolling machine tool is a kind of high precision, high efficiency and high automation deep hole processing machine tool. With advanced deep hole drill bits such as gun drill, BTA drill, spray drill, etc., through one continuous drilling, the surface roughness of traditional machine tool can be achieved through multiple processes such as drilling, expanding, reaming, etc. Next, small braid with you to learn how to solve the chip removal problem of the next scraping and rolling machine.
When scraping and rolling machine tool works, there will be the phenomenon of unsmooth chip removal. In case of this kind of failure, the mixing concentration of lubricating oil can be adjusted, the amount of coolant can be increased, and the liquid pressure can be adjusted. However, after the mixing valve is closed, the liquid pressure can be adjusted to 2.5-3.1 MPa. After replacing the tool, check the cutting situation, adjust the cutting parameters accordingly, and then observe the tool output of scraping and rolling machine tool Check whether the hole is blocked. If necessary, regrind the tool and check the gas pressure. The lower limit of the air pressure shall be controlled below 5kg, and the hole pressure less than 10 mm shall be higher.
