Marking and basic parameters of cutting wheels

Cutting wheels are one of the most affordable and simple tools that allows you to cut various workpieces according to given parameters. Products are produced quickly, work becomes more efficient. But provided that abrasive cutting is carried out correctly and the wheel is selected correctly.

Abrasive cutting wheels from the manufacturer and their advantages

If the manufacturer of cutting wheels is reliable enough, then the wheel will allow you to increase your productivity and perform more and better operations. A novice craftsman can work with cutting wheels when you need to make simple products, an introductory briefing is enough.
They are easy to distinguish from each other, because there is a classification by purpose:

1. Reinforced wheels with a diameter of 115-230 mm, the maximum working speed reaches 80 m / s. They are used in everyday life and for small construction needs, mainly for angle grinders.
2. 250-900 mm - diameter of reinforced wheels designed for work on stationary machines developing speeds up to 100 m / s. They are installed in rooms for the production of serial batches.

Before buying abrasive wheels wholesale or retail, you need to decide on the brand and type of device you need. Therefore, it is worth learning more about what types exist and what they are used for.

Recommendations for the use of cutting wheels

For each circuit, there are a number of requirements regarding the technical and structural part, as well as operational safety. The following recommendations should be highlighted:

• The outer diameter of the disc must be selected for a specific device so that its parameters do not exceed the maximum permissible values specified by the manufacturer.
• The thickness is selected based on the material and cross-section of the workpiece.
• Control of permissible deviations in circle height.
• Correct lap runout indicators. Deviations from the standards can lead to serious changes in the quality of work.
• Technical level of design, moderate imbalance. Otherwise, there is a risk of increased vibration and rapid destruction of the moving part.
• The appearance should be such that it can be called whole and of high quality, which means the absence of visible defects, cracks, and extraneous holes.
• The level of maximum speed in operation. This depends on whether the circle will be created on a bakelite bond or without it, or on a vulcanite substance.
• The scope of use of the products must correspond to their intended purpose. This includes cutting metal and non-metal.
• Compliance of cutting coefficient indicators with DSTU requirements.
• Safety check of each unit.
• Make sure that the symbols on the surface and packaging match.

Checking the presence and validity of markings is an important part of the inspection process before buying cutting wheels wholesale or retail. Therefore, it is worth understanding these combinations of letters and numbers.

Marking

If the discs were manufactured in accordance with standards and in compliance with the requirements, the packaging must be marked:

• name of the manufacturing organization;
• country of manufacture;
• image of a round object;
• release date, as well as expiration dates;
• availability of a certificate;
• security guarantee;
• speed limit of the equipment rotation frequency in operation;
• color coding of device capabilities in the form of a ribbon;
• the presence of a barcode.

If one or more items are missing, you should think about the advisability of purchasing a product of dubious reliability. After all, buying cutting wheels in bulk is not a problem, it is more difficult to implement your plans later.

How to use abrasive discs safely

You can buy abrasive wheels wholesale from the manufacturer, knowing that he followed all the necessary rules during manufacture.

When using the tool, you must observe the following precautions:

• cutting wheels cannot be used as grinding equipment, use the side surface of the product;
• monitor proper storage and disposal as the expiration date approaches;
• refuse to use damaged discs;
• full protective equipment for the employee is mandatory;
• constant monitoring of the correctness of the installation and the absence of deviations from the norm in the operation of the mechanism;
• Run the disk before starting work for at least 2 minutes.

It is important to buy metal cutting discs where the seller can guarantee the reliability and safety of the wheel. Buy only what you are sure of!
