Grating ruler displacement sensor inspection
After the installation of the grating line displacement sensor, can be connected to the digital display, move the table, observe the number of table count is normal.
Select a reference position on the machine to move the operating point back and forth to the selected location. Digital reading should be the same (or return to zero). You can also use the dial indicator (or dial indicator), so that the dial indicator and the digital meter at the same time transferred to zero (or memory starting data), back and forth many times back to the initial position, observe the number of tables and thousands Whether the table data is consistent.linear scale
Through the above work, grating ruler displacement sensor installation is complete. But for the general machine tool processing environment, iron, cutting fluid and oil more. Therefore, the sensor should be equipped with a protective cover, the design of the shield is in accordance with the shape of the sensor to enlarge the size of a certain space to determine the size of the shield is usually a rubber seal, so that it has a certain degree of water and oil.
