Increasing the Smoothness of CNC Drilling

The smoothness of the guide rail movement directly related to the use of CNC drilling machine effect, so, in order to better enhance the use of CNC drilling machine effect, it is necessary to take certain measures to ensure the smoothness of the rail movement, the following method is that we have repeatedly tested The conclusion, can effectively enhance the smoothness of CNC drilling machine guide movement.
1, to improve the processing technology, give full play to the effect of dynamic pressure lubrication, can greatly improve the sliding rail motion smoothness.
(Deep) scraping guide is the traditional rail scraping process, according to the number of points per square inch, and to ensure a certain depth to the processing acceptance.Wide (shallow) scraping process instead of point (deep) scraping is to improve the rail Wear resistance of the effective method of metal cutting machine tools on the use of wide (shallow) scraping process, can be very effective customer service weight, low speed crawl and wear fast these three shortcomings.
The test results show that the friction coefficient of the wide scraping guide is only 10% -50% of the scraping guide rail. Under the contact pressure p = 0.0135MPa, the L-AN10 lubricating oil is used for the wide scraping guide rail. The width of the scraper blade is wide, the scraper is light, the scraper is only 1-2 microns wide when the cutting edge, and thus the effect is high; wide scraping the critical speed of the crawler track than Point scraping guide low.
2, the friction material properly matched, you can get a good anti-climbing effect, can greatly improve the sliding rail motion smoothness.
Anti-adhesion properties of good material matching are: cast iron on hardened steel, cast iron on plastic, steel on bronze, etc. Especially PTFE, infiltration of fluorine plastic sintered bronze, friction coefficient is very low, and the static friction coefficient difference is very small, Has an excellent anti-climbing effect.
