How to Judge That the Abrasive Belt Has Expired in Use

Judging whether the use of the abrasive belt has expired is mainly based on its wear condition. When it enters the end of wear, the service life of the abrasive belt will end, indicating that a new abrasive belt needs to be replaced. Whether the wear has entered the final stage is mainly reflected by the following parameters:

Ⅰ. How to judge that the abrasive belt has been worn and expired

1. When the material removal rate or grinding efficiency drops to the specified value, it can be considered that the service life of the abrasive belt has expired for this grinding (given grinding amount and other conditions).

2. Grinding force. When the grinding force exceeds a certain value during the grinding process, it can also be used as a sign that the service life of the abrasive belt has expired.

3. Grinding temperature. During the grinding process, if the grinding temperature is better than the specified standard, it can also be considered that the service life of the abrasive belt has expired. In practical applications, the most direct way to determine whether the temperature exceeds the standard is to observe whether there is burns on the surface of the workpiece.

The above judgment is only from one aspect of grinding performance. In actual production, production cost is also a very important factor, because replacing the abrasive belt too early means increased tool consumption, too late, the grinding efficiency is too low, the labor cost increases, and the cost increases.

Therefore, to judge whether the abrasive belt should be replaced, the two must be combined, and the ultimate goal is to minimize the cost per piece.

Statistics show that: through the analysis of the average cost of a single product, when the abrasive belt grinding is carried out at the highest productivity, although the life of the abrasive belt will be shortened, this is not the same as in order to obtain the longest service life of cloth sanding belts. Compared with the use of lower efficiency, it is more economical.

For a belt with high initial grinding efficiency, its most economical life may be only 1/3 of its life when ground at low efficiency. Of course, it would also be more economical to process the blunts sequentially and use them for finer machining, but that's another story.

An easy way to decide when to replace cloth sanding belts for the lowest cost per piece; cost curves are derived from test results. The productivity curve represents the number of parts machined at different times.

Ⅱ. How to improve the polishing efficiency of the abrasive belt

Modern belt polishers show the best possible fit between motor power, machine design, contact wheel and belt. Belt polishing is a very economical method for deburring, trimming and surface preparation.

With high-power motors, durable construction and suitable abrasive belts, reasonable and safe operation can be achieved even under high loads. Modern belt polishers excel due to the optimum combination of motor power, machine structure, disc and belt.

Due to the continuous development of technologies such as abrasive belts, the role of abrasive belt polishing in the metalworking industry has become irreplaceable.

Metalworking tasks such as surface polishing, circular polishing, correction polishing and grinding, radius polishing, chamfering and deburring can all be successfully accomplished with state-of-the-art abrasive belt polishing equipment. With a modular design, this can increase the flexibility of the equipment and reduce costs.

Industrial batch processing companies place high demands on the flexibility of the equipment used. Using a modular technical solution can reduce production costs and save storage space in the production workshop.

The return on investment of abrasive belt equipment is also very high if only the components required for each processing step need to be added to the basic equipment.
