Put the comparative light support and clamp in the large measurement position: for the comparative light instrument seat, its support is clamped in the larger position: after the heat is applied, put the comparative (or comparative collection) sensing element in the clamping center, and leave a corresponding size of the block or effect on the working warehouse, and add 2N force along the direction of the auxiliary line of the light support hole to explore the basic code, the dead violence ratio The change of the indication value of the comparator
Install the comparator (or comparator sensor element) in the holder, align the comparator, and then apply 80 degrees of force to the four symmetrical positions of the front, back, left and right of the fixed workbench. The comparator indication change axis is installed in the optical hole: use a protractor to measure in the front, back, left and right directions

Put the comparator (comparator) The comparator sensor element) is sold to the special hole towel, and a piece of it is assembled on the workbench. The comparator (or comparator sensor element) is adjusted to the sensitive block, and its alignment with the comparator at a certain moment is adjusted. The minimum position is set, and the adjustment device is adjusted to a certain degree. The comparison instrument indicates a certain rate, and then the adjustment device is adjusted in sequence. The change in the value of the comparison value can be seen at the end of the comparison. The product block can be adjusted to a certain value.

Install the chemical comparator (or comparator sensor element; install it into its holding hole, make the comparator and the operating table level and connect with each other, and it is necessary to have a slight gap when external force is applied) and align it with the comparator. The instrument is for a stabbing minister, but the government expands the frequency of the teacher, now multiply the display of the exchange of
will have more mm flat intention than the teaching proposal to install the light to hold the hole, the amount of Kan research in 1. The piece is on the table, 1:, put the flat measurement amplitude of 1/2 and the amount of support to restore the Pa, after comparing the heat received, the same position of the gold block will be donated to the flat and converted to four sides, and the whole bad section of 1 will be repeated to get four positions, and the relative two sides will pull the money to get it. For the parallelism error, the road will be lowered to the front and the effect will be allowed to be level 2 flat (or flat as a table). The lighter the instrument is, the higher the support height will be. Make the sensor comfortable to connect with the ball and take 1 minute of corrosion and dryness. For example, the calibrator is slow. After heating, apply force slightly on the relative sides of the melting point. The width of the sensor's indication change will be twice the specified value. Use the flat crystal finishing dry belt method to check.
Pre-install! 430mm×15/mm mandrel, the comparator (or chemical comparator sensor element) is clamped to the special fixture, and the special inspection fixture is moved 15mm on the top workbench. The comparator is respectively inspected on the upper lifting line and the measuring line of the two points of the mandrel. The square difference of the square product of the two indications is half of the coaxiality error. The 3mmmx200mm special mandrel is effectively measured on the two V-shaped lack of support rate. The comparator (or chemical comparator sensor element) is clamped to the special inspection fixture, and the special The inspection fixture moves on the workbench, and the fast comparison is collected on the mandrel line and the slow comparison line respectively. The square root of the sum of the two squares is the coplanarity difference. The inspection only requires equal installation and maintenance. The instrument is used to measure the coplanarity of the product. The 2-frequency plane of the product is the center of the product) mm. Special mandrel: 430mm*.
