6.2.1 Tooth diameter bzxz.net
Method: Use a lever to measure the diameter of the reamer. According to the true diameter of the reamer, select the size, calibrate the position of the disc, and then compare and measure. At the beginning of the calibration part, measure each section one by one. The measurement is made to swing slightly in the axial plane of the chain cutter until the pointer shows a reverse value. Note the indicated value. At this time, the sum of the constants of the ruler and the pointer is considered to be greater than the actual measured length of the cutter. Method 1: Measure the diameter at the beginning of the calibration part according to the method. The diameter difference is the diameter of the calibration part. Method 2: Measure the diameter of the calibration part according to the method. At the beginning of the calibration part, perform a second test. The diameter difference between the calibration beginning and the end is the diameter of the calibration part. Method 3: Measure the diameter of the calibration part according to the method. Method 4: Measure the diameter of the calibration part according to the method. Method 5: Measure the diameter of the calibration part according to the method. Method 6: Measure the diameter of the calibration part according to the method. Method 7: Measure the diameter of the calibration part according to the method. Method 8: Measure the diameter of the calibration part according to the method. Method 1: Measure the diameter of the calibration part according to the method. Method 2: Measure the diameter of the calibration part according to the method. Method 3: Measure the diameter of the calibration part according to the method. Method 4: Measure the diameter of the calibration part according to the method. Method 5: Measure the diameter of the calibration part according to the method. Method 6: Measure the diameter of the calibration part according to the method. Method 1: Measure the diameter of the calibration part according to the method. Method 2: Measure the diameter of the calibration part according to the method. Method 2: Measure the diameter of the calibration part according to the method. Method 3: Measure the diameter of the calibration part according to the method. 6.3 Inspection tools: ruler, 4-meter scale, universal 1.F microscope, digital display ruler with graduation value of 0.001mm, V-shaped ruler with graduation value of 0.001mm or 0.01mm.

Part and calibration part The runout of the cone part and the round part are measured at the beginning of the calibration part, and the runout of the part is measured at the middle position of the part.
7.2 Inspection method
Figure 1. Place the reamer on the sharp rack, and hold it with the sharp rack (the set of the reamer is mounted on the chain shaft), so that the probe of the indicator directly passes the controlled part, and the chain is rotated slightly. The difference between the indicated value and the recorded value shall be 7.3. The measuring instrument shall be a meter with a value of 0.01mr or a meter with a value of 0.001mm, a dynamic tester, or a magnetic meter stand. 3. B.

See Figure 2. 2. The working surface of the angle ruler is placed on the adjacent tooth of the measured tool, and the working surface of the front angle ruler is adjusted to contact the front surface of the measured tooth. And the working surface of the angle ruler is in contact with the tooth of the measured tool, and the front angle value can be read, Figure 2

See Figure 2, the working surface of the angle ruler is placed on the tooth top of the adjacent tooth of the measured tool, and the working surface of the back angle ruler is in contact with the back cutting edge of the measured tooth, and the back angle value can be read. Design: When it is difficult to use the tool or there is no tool that can be used, you can use a multi-blade angle ruler or a universal tool microscope to measure. 8.3 Testing equipment || tt || multi-blade angle ruler or universal tool microscope.

16 Dimensions (4) and symmetry of hand-held knife square heads 16.1 Inspection method
Method 1: Measure with a set gauge
JB/T10231.92Q02
First, use a micrometer or vernier caliper to measure the actual size of the square head, which should comply with the product standard. Then use a set gauge (track gauge) to check. The head is qualified when all the heads are in the gauge.
Method 2: Measure with an indicator table
First, use a micrometer or vernier caliper to measure the actual size of the square head, which should comply with the product standard. Then install the knife on the pre-tip of the dynamic inspection: the symmetry of the two sets of planes measured by the table should not exceed the product standard, see Figure 5. Net: When there is no, it can be used in the second method. 16.2 Testing equipment
