When sharpening and finishing tools, diamond plates 12А2-20 for tool sharpening. Consumables are used to work with carbide metals. The wheels of this model meet the characteristics - strong and fragile.
Cup 12A2-20 degrees is installed on a manual or automatic tool. It is also suitable for working on an angle grinder. Using discs 12A2-20 degrees, sharpening, finishing and processing of metal cutters is carried out.
How to choose consumables
Cups should be selected based on the following criteria:
Grain. In order for the tool to have a smooth, even surface after processing, the work is carried out in several stages. Choose a consumable with a certain degree of graininess. In total there are three types - large, medium or small grain. It is in this order that discs are taken for the preliminary and finishing stages of processing.
The content of granules in the layer applied to the cup. There are three degrees of percentage of diamond granules in the layer on the cup: 100, 50, 25%. 100% particle concentration is an indicator of 0.878 mg per 1 mm3 layer. The higher the concentration, the stronger the layer will be removed from the metal surface.
To preserve the functionality of the cutting tool, it is important to choose the right consumable.
Characteristics of the composition on the surface of the cup
In the process of applying diamonds to the surface of the consumable, a filler is used and, of course, a binder. This is a composition that allows the granules to stick as tightly as possible on the surface of the disc. Depending on the desired result, the master selects the model of the working tool for processing the metal part of the equipment.
Also, there are types of diamond powders. Marking ACM, ASN is used in work with hard-alloy metals. For fragile incisors, they take a consumable marked AC4, AC6. Allows you to carry out thin, neat work.
Disks are also chosen according to the frequency of use. For a workshop where the cup will be in use constantly, for a long period of time, wear-resistant products should be chosen. For home use, you can buy less expensive discs.
The choice should always be focused on the expected result. Diamond cups will help you choose a craftsman who often uses them in his work and is aware of the features of marking, use in certain conditions.
