Processing technology of dovetail ruler

In order to reduce the production cost of the dovetail ruler, so that the price of the dovetail ruler can occupy the market in the competition, 99.8% of the dovetail ruler manufacturers use the manual scraping process. Although manual scraping is relatively backward, for the dovetail ruler, when the precision is relatively high, it is a processing technology that cannot be replaced by any mechanical processing.

In order to improve the service life of the dovetail ruler and ensure its working accuracy, it is recommended to control the scraping depth above 0.02mm, which can ensure a longer service life and verification period for the dovetail ruler. According to the introduction of the scraping depth and the measured data of the scraping depth according to the relevant information, the processing requirements of this process can be achieved.

Vibration lines appear on the appearance of the dovetail ruler, and the surface roughness of the product is increased, which affects the accuracy and even the appearance. With the scraping process, the above problems rarely occur. Prevent small-scale local distortion on the working surface of the dovetail ruler to ensure the accuracy of the use of the dovetail ruler. Check the microscopic quality of the working surface of the dovetail ruler, that is, the flatness of the tiny peaks and valleys. The high surface microscopic quality and good wear resistance can ensure the service life of the dovetail ruler.
