Rock Drilling Tools: What is a cut-off tooth? How to select?
Picks are mainly used in coal shearers and roadheaders, and picks are also used in some excavators and milling machines. However, different models and different construction environments require different types of picks. So, what are the commonly used pick models? What kind of working conditions and machines are they suitable for?

What are the uses, functions and values of truncated teeth?
As one of the most consumed accessories in mining equipment, picks play an important role in improving mining efficiency. In terms of value, picks can contribute to the development of the energy industry, thereby improving the convenience of life for ordinary consumers. For example, water, electricity, etc., all require the supply of coal energy, which is of great importance to the survival of human beings.

Coal mining machine cutter teeth cutting coal seam classification
The spatial distribution of underground coal seams presents various changes, which are distinguished from their spatial geometry and material properties, and coal mining opportunities meet different coal seam cutting function requirements.
How can the surface of cut-off teeth be well strengthened by wear resistance
During the construction of the coal mining cutting face, the pick needs to bear huge compressive stress and impact load, so the alloy head and wear-resistant layer of the pick will be worn. The pick needs to be replaced after wear and tear. Installing a new pick to continue working is a consumable. Therefore, the pick has become one of the most widely used coal mining machinery parts. So how can we do a good job of strengthening the wear resistance of the pick?
