Why sometimes there are abnormal wear marks during grinding work?

  • Author:Dora Zhang
  • Release on:2021-01-20
Sometimes during construction, abnormal wear marks appear during polishing, which may be caused by the following reasons:




1. The horizontal positioning screw of the grinder is not adjusted in place.


2. The ground is not clean, and hard impurities are embedded in the drainage and heat dissipation seams of the working surface of the grinding block.


3. When the new and old grinding blocks are mixed, the thickness of the grinding discs is inconsistent, which may cause abnormal wear marks on the ground..



4. The grinder stays in one position for a long time during dry grinding or dry throwing on the ground, and poor heat dissipation may cause burn marks on the grinding disc or the ground.



5. The bearing of the grinder is worn or the screws are loose. This situation may cause the grinding disc to swing. Certain numbers of grinding discs may bring out wear marks that are difficult to eliminate on the ground. Such wear marks usually require thicker ones. Abrasive blocks can be eliminated.





It is recommended to use (Single Rhombus Segment Husqvarna Bar) of BOREWAY manufacturer, Quick Change Z Segment Bar For Suppliers , Husqvarna 2 Segment Diamond Grinding Bar For Suppliers and so on.

There are also various types of metal grinding blocks, resin grinding discs, polishing discs, ground grinding blocks, litchi surface tools and other tools.
