Product Description

Smooth ring gauge is a kind of precision measuring tool used to measure the size of workpiece, can be used as size reference, can also be used for comparison measurement, can also be directly used to verify the table, can be customized according to user requirements of various specifications smooth ring gauge. Smooth ring gauge in addition to the standard national standard, but also according to the user's different requirements according to its drawings processing.

Smooth ring gauge material is YG8, hardness is HRC69-74°.

The smooth ring gauge is a high accuracy measuring tool with the diameter of the inner hole of the middle section perpendicular to the axis as the working length, through which the hole measuring instrument and measuring tool are verified and calibrated.

Use:

Use end gauge only by hand screw (smooth limit gauge by hand push), do not allow percussion, forced pressure or other auxiliary tools, otherwise it will not only cause false detection. And it can damage the gauge. In use, the gauge can also be coated with a very thin layer of easily flowing oil to reduce friction resistance.

Gauges must be kept clean, especially to prevent screw teeth from working with fine iron dust and other dirt. Otherwise, it will not only bring inspection error, but also cause serious wear and damage to the gauge. Screw gauge should not be knocked. Special care should be taken when using it. It should be washed and dried immediately after use, coated with a thin layer of anti-rust oil, and placed in a special box individually. Long periods of uninterrupted hand-holding of the gauge should be avoided. Gauge handles are best insulated to avoid hand temperature.

Gauge before use. Should be put together with the workpiece to be inspected isothermal, so that the temperature balance between the two, never use the gauge to inspect the workpiece just finished with higher temperature. The newly made thread gauge should be checked whether it is qualified or not, and the thread gauge in use should also be checked regularly. The verification period depends on the frequency of use and the speed of wear of the gauge.

High hardness tungsten steel, solid material; The stable thread surface is made in accordance with strict quality control procedures to ensure high quality and improve wear life; Ring gauge in accordance with the appearance can be divided into: smooth ring gauge also called ring gauge, parallel smooth ring gauge, etc.; According to the use and different manufacturing standards can be divided into: standard ring regulation, SK standard ring regulation, German standard ring regulation, pipe ring regulation; According to the different manufacturing materials can also be ceramic ring gauge and metal ring gauge difference.

According to the manufacturing accuracy and measurement uncertainty, it is divided into three grades: 1,2,3. The applicable scope of various standard ring gauges is as follows:

A. The standard ring gauge is used for calibrating and verifying the instrument of standard ring gauge 2, or for calibrating and calibrating high-precision air momentum meter and electronic plug gauge.

B. The standard ring gauge is used for measuring size calibration of length measuring machine and horizontal length measuring instrument, or for calibration and calibration of pneumatic meter and electronic plug gauge with uncertainty of 1-2 micron.

C. The standard ring gauges are used for calibration of inner diameter gauges, inner diameter micrometers or pneumatic and electronic plug gauges with response accuracy.
