Inspection method
Install the inspection rod on each drill axis hole, and use the caliper to measure any four adjacent drill axis rods.
L is the measured hole distance accuracy
Install the inspection rod on the drill axis hole, and the percentage gauge probe contacts the rod. Rotate the drill axis
Install the inspection rod on the drill axis hole, and the percentage gauge probe contacts the rod. Slowly lift and lower the drill axis
Install the inspection rod on the end axis holes in the same row, and fix the dial indicator on the curtain board. The gauge probe contacts the rod and measures the maximum difference (detect five points in symmetrical positions)
Install the inspection rod on any corresponding drill axis hole, and place the square ruler against the rod. Use a feeler gauge to inspect the gap

QB/T16231992| |tt||Inspection items
Parallelism of each row of drilled holes to
test piece reference surface
Inspection method of drilling axis to
Drill two holes in each row of the test piece and install inspection rods. The difference in distance from the two holes in the same row to the side base surface is
Install the inspection rod in the test piece hole, use a 50:0.25 ruler at right angles to the test piece reference surface to contact the inspection rod, and use a feeler gauge to measure the maximum value in two perpendicular directions
Note: For hardwood boards or artificial boards with a moisture content of less than 15%, if the parallelism of the test piece reference surface does not exceed 1000:0.10, the straightness of the reference surface shall not exceed 1000:0.10. The size of the test piece: length×width×thickness (1000mm×400mm×19mm). 5 Test methods
5.1 The geometric accuracy and working accuracy of the machine tool shall be carried out in accordance with the provisions of Article 4.4. 5.2 The appearance quality shall be carried out in accordance with the provisions of Article 4.3. 5.3 Idle operation test
5.3.1 There shall be no abnormal vibration and noise during idling operation. 5.3.2 Start and stop the movement 10 times continuously to test the reliability of the action. 5.3.3 Test the flexibility of the operating mechanism.
5.3.4 The sound pressure level of idling noise shall not exceed 85dB(A). The inspection shall be carried out in accordance with the provisions of ZBJ65015. 5.3.5 The electrical system works accurately and reliably. 5.4 Load test
5.4.1 The working accuracy shall be inspected in accordance with Article 4.4.5. 5.4.2 The load test is generally carried out in the manufacturer and, if necessary, in the user's factory. 6 Inspection rules
6.1 The machine tool shall be inspected and qualified by the factory inspection department in accordance with the provisions of this standard, and a certificate of conformity shall be issued. 6.2 The machine tool shall be inspected at the factory according to Article 4.4, and can only leave the factory after the certificate of conformity is issued. 6.3 Type inspection
The type inspection items are all the technical requirements of this standard. When one of the following situations occurs, a type inspection must be carried out. New product trial production or old product transformation appraisal; a.
After formal production, when there are major changes in structure, materials, and processes that may affect product performance; c.
QB/T 1623-1992
When the national quality supervision agency proposes to conduct type inspection; During normal production, it shall be conducted once a year;
When the product is resumed after a long period of suspension; e
When there is a significant difference between the factory inspection results and the last type inspection results. 6.4 Type inspection rules
For products produced in batches, each batch shall be randomly inspected at a sampling rate of 10%, and no less than one unit shall be inspected in each batch. If it is unqualified, double sampling will be conducted. If it is still unqualified after double sampling, the batch of products will be judged as unqualified. Marking, packaging, transportation
7.1 Fix the label at the appropriate position of the machine tool. The type, size and technical requirements of the label shall comply with the provisions of JB/T8. 7.2 Packaging
