3 Technical requirements
3.1 Basic dimensions
Main types and sizes of plates according to GOST R 55433.
3.2.1 Plate made from hard alloy or high speed steel.
Brand tool material the manufacturer chooses, depending on the workpiece material and machining conditions.
Physical-mechanical properties and durability of the material of the plates of hard alloy must not give in to the VK8 alloy grade according to GOST 3882; material plates of high speed steel — steel of grade R6M5 GOST 19265.

4 acceptance Rules
4.1 To verify compliance plates requirements of this standard the manufacturer shall carry out acceptance inspection.
Plate on control present parties. The party must consist of plates of the same size, the same brand of tool material, manufactured in one technological process for a certain period of time and simultaneously presented for acceptance on the same document.
4.2 During acceptance inspection should be monitoring the appearance, dimensional parameters and the parameters characterizing the roughness of the surfaces, the quality of heat treatment for steel plates, matching stamps for carbide inserts.
Acceptance inspection should be carried out in the following volume of sample:
— compliance 3.2.3 — solid;
— compliance 3.2.1, 3.2.2, 3.2.4−3.2.8 — 5% from the party, but not less than 10 plates.
Compliance plates requirements 3.2.1 define:
— for plates of solid alloy GOST 3882;
— for plates of high speed steel — GOST 19265.
4.3. Upon detection of the first sample one plate not conforming to the requirements of this standard, from the same batch are selected a second sample of the same volume.
If the second sample is detected at least one plate, not meeting the requirements of this standard, the batch is not accepted.
5 Methods of control and testing
5.1 appearance of the plates is controlled visually. The presence of cracks check by means of a magnifying glass LP-1−5according to GOST 25706 or flaw. Allowed the appearance of plates to control the visual comparison with the samples approved in the established order.
5.2 hardness Control plates of high speed steel — GOST 9013.
5.3 surface Roughness of the plates should be checked by comparing with the samples of roughness according to GOST 9378 or with control samples having parameters of a roughness of not more than specified
5.4 in the control of dimensional parameters of the plates used methods and means of measurement error which should be no more than:
|— the values specified in GOST 8.051,
|— 35% check the tolerance on the angle||-||«||«||corner||«||;|
— 25% of the tolerance check parameter in the measurement of deviations of form and position of surfaces.
5.5. The reliability of removable profile plates (tests for performance, the average and the prescribed periods of resistance) must conform the instrument to the appropriate cutting tool.
6 Transportation and storage
Transportation and storage of plates according to GOST 18088.
