The grating installation method:

One, according to the principle of Abbe error, the sensor should be installed near the work table of the machine tool body surface.

The grating length two, according to the machine stroke, effective measurement length is greater than the stroke of machine tool, namely, both ends of the stroke should be at least 20mm margin is left.

The main pitch : L=L 0 +147 ( L 0 nominal size, unit mm ).

Three, the grating used in surface M6 six angle screw fixation, to ensure that the main ruler surface with the positive and moves in the direction parallel, error less than 0.1mm/m.

Four, the reading head hole spacing is 60± 0.1mm M4 six screws fixed to a base angle relative to the main ruler operation, or with M6 six angle screw is fixed on the mounting accessories, installation accessories fixed reading head is designed to adjust the amount of 1mm. The reading head fork and shell length of friction sound can not move. After the reading head base with the main scale reference surface. When the installation error, can be read head and flat 0.1~0.2mm, 0.8± 0.15mm gap between the reading head and the main ruler. Try to make the reading head mounted on a non moving parts, fixed to the signal lines, signal lines arranged in parallel with the power line is prohibited.

Five, in the machine tool guide rail mounting grating shall be provided for the limiting device.

Six, the grating ruler after installation should be examined carefully, to ensure the correct installation before moving worktable, movement there should be no abnormal sound, power inspection technology is correct, check available standard gauge block comparison. If there is corrected by digital display meter error.

Seven, after all the normal should be grating shield fastening, grating shields should be the main ruler of all good protection, prohibited the greasy dirt, metal chips into the main ruler.

Installation instructions

The installation mode selection must pay attention to the chip, the coolant and oil splashing direction, A, B, C three ways to correct the reading head is fixed in the machine tool, the best non moving parts, in order to simplify the cable laying.

Installation:

The grating ruler body and the reading head are respectively arranged on the two parts of machine tools relative to the requirements of installation, as shown in fig.:

Installation accuracy

The grating ruler two perpendicular sides and machine tool motion in terms of the parallelism error is greater than 0.2 mm in length within the range, the reading head and the grating of two adjacent parallel to the plane of the gap 1.2-1.5 mm, as shown in fig.:

Check

Connect the power supply, mobile work station, observation of digital display meter count is normal, as shown in the figure, the percentage table or other measuring tools, to return to the initial position and digital display meter and zero or memory of initial data from multiple times, zero error or memory of initial data should not higher than +0.01 mm
