In the precision machining industry, precision is crucial, and how to ensure that the accuracy can meet the requirements? At this time, inspection tools play a very important role, so what tools will be used in precision parts processing? Take a look below

1. Dental regulars

The dental gauge is used to experience the quality of the thread, according to the national standard and made, there are external threads and internal threads, the external thread is understood as a screw to test the standard of the nut, the internal thread can be solved into the nut used to test the screw standard

2. Needle gauge

The needle gauge is the standard used to test the inner hole, generally there are two, one for the general gauge, one for the gauge, just like a metal rod, the gauge must be able to put into the hole, the gauge must not enter, any one of the two errors means that the size of the product is unqualified

3. Vernier calipers

A vernier caliper is an inspection tool that measures length, inner and outer diameter, and depth. The vernier caliper consists of two parts: the main ruler and the vernier attached to the main ruler that can slide. The main ruler is generally measured in millimeters, and the vernier has 10, 20 or 50 divisions, according to the different divisions, the vernier caliper can be divided into ten-degree vernier calipers, twenty-degree vernier calipers, fifty-degree vernier calipers, etc., the vernier is 10 divisions of 9mm, 20 divisions are 19mm, 50 divisions are 49mm. There are two pairs of movable claws on the main ruler and vernier of the vernier caliper, the inner measuring claw is usually used to measure the inner diameter, and the outer measuring claw is usually used to measure length and outer diameter.

4. Micrometer

Micrometer and vernier caliper are used to check the external inspection, inner diameter, depth, but relatively single, each specification must buy different micrometers, such as outer diameter micrometers, inner diameter micrometers, micrometers are more accurate than vernier calipers, can be accurate to 0.01 mm

5. Altimeter

The height meter is used to measure the depth dimension of the product, such as the size of the end face from one end face to another, and the height meter measures the size more accurately than the vernier caliper, which can be accurate to 0.001mm
