6.1 Testing method
6.1.160°, 90°, 120 hook drill
And the thousandth is measured directly in the middle of the rigid column part, B.1.2 Drill with guide column
Use the lower scale to measure directly in front of the blade part. 1

6.2 Testing equipment
The value is 0.0mm or 0.001rm.7 Taper angle of drill cutting part
7.1 Testing method
7.1.1 Testing of drill with even number of teeth
Use universal angle ruler to measure, see Figure 1.
7.12 Testing of drill with odd number of teeth
Use run-out inspection instrument and angle ruler to measure, see Figure 2.
Note: For the precise measurement of the angles of other parts, you can use universal ruler microscope to detect, 7.2 Testing equipment
Single negative ruler, run-out inspection instrument and angle ruler or square microscope. B. Position tolerance of specification
8.1 Test method
8.1.1 Oblique circular run-out of cutting edge or axial circular run-out of end edge2
On a V-shaped drill, the end face of the shank is close to the positioning notch (the center hole of the end face of the shank and the fixing block are like a ball), and the measuring head is raised and the middle of the front edge is scratched between the middle of the end edge and the middle of the end edge. The drill is rotated, and the maximum change in the water value indicated on the indicator is the corresponding axial run-out or end axial run-out||tt| |8.1.2 The radial runout of the blade or the guide column should be measured on the actual surface, and the indicator should be close to the front part or the guide part of the drill. The maximum value of the indicator value must be the radial runout or guide runout of the return circle. 8.2 Testing equipment
8.21 The axial circular runout and oblique circular runout of the end blade are tested with a value of 0.U1mm. The indicator, table frame, V-shaped iron or steel, grade 1 inspection plate and positioning block: 8.2.2 The runout inspection of the indicator is 0.0lm, and the inspection instrument and table nest are used. 9 Rake angle: back angle, helix angle
9.1 Detection method
9.3.1 Rake angle
Use a multi-blade angle gauge to detect the rake angle: make the working support of the front angle gauge rest on the tooth of the measured tool, adjust the second working center of the measuring tool to contact the measured tool, and make the back angle ruler work surface contact the pseudo tooth top of the drum measuring tool, then the full value of the rake angle can be read. 2
9.1.2 Back angle
JB/T10231.10—2002
Use a multi-blade angle gauge to detect the back angle: make the working support of the front angle gauge rest on the tooth top of the measured tool, adjust the measuring tool to make only one working surface of the angle ruler contact the effective back tool surface, that is The rear pin value can be read out. Note: For the sticky side that is difficult to inspect or there is a dispute, a universal tool microscope can be used for inspection. 9.1.3 The screw angle is measured by using a multi-tool microscope. The micro drill is placed horizontally on a V-shaped iron or on a neck rack, so that the M-line of the microscope coincides with the axis of the drill. Then the M-line is rotated to make it tangent to the cutting edge and the degree of the screw is obtained. 9.2 Inspection tool: a multi-tool microscope with a multi-tool angle control ruler. 10. The diameter of the guide column and the guide column hole diameter of the drill with a guide column hook are inspected directly at any position of the back part with a micrometer. The guide rod diameter is inspected with an internal light indicator at two positions near the mouth and the middle of the toilet fence hole.
10.2 The accuracy of the tester
The micrometer with a graduation value of 0.01mm0.001mm, the inner diameter indicator with a graduation value of 0.01mm0.001mm. 11 The diameter of the hook drill part of the ear handle
According to the provisions of 10.1 in JB1(231.1-20.
12 The table handle
According to the provisions of Chapter 6 of JE/T10231.1-2(K1). 13 The total length of the drill and the length of the working part
According to the provisions of 10.1 in B1V231.1-2001. 14 Hardness
According to the provisions of IB/T10231.1-2001 Chapter 11. 15 Marking and packaging
According to the provisions of Chapter 13 and Chapter 14 of 102.31.1-2001.
