2. Applications
Roadheader cutting picks are suitable for underground mining, tunneling and excavation purposes.
* Coal shearer cutting drum
* Roadheader cutting head
* Tunneling and excavation machines
* Coal mine roadway excavation
* Cutting through rock-coal mixed strata
* Breaking soft rock and medium hard rock
* Mining development headings
* Tunnel construction in civil engineering
* Underground engineering excavation
3. Advantages
Cutting picks are subjected to high impact loads and abrasive wear while cutting. Choosing the right pick can improve cutting efficiency, decrease machine vibration and reduce frequency of pick replacement.
The alloy steel body allows for high strength and toughness. Heat treating the pick allows it to meet hardness and impact requirements. We can also use different cutter head structures and carbide tips to fit harder strata and improve service life.
4. Custom Options
We can supply cutting picks according to machine model, drawings or working conditions.
Available customization includes:
Pick type
Shank diameter
Shank length
Cutter head shape
Carbide tip size
Body material
Hardness requirement
Heat treatment process
Packaging method
5. FAQ
5.1 What is mining cutting pick used for?
Mining cutting picks are used with roadheaders, coal shearers and tunneling machines to cut coal, excavate tunnels and mine roadways.
5.2 What kind of materials are cutting picks made of?
42CrMo, 35CrMnSi and Si- Mn- Mo alloy steel are some of the common materials. Heat treatment is also done to enhance hardness and impact toughness.
5.3 What should be the hardness of the pick body?
The hardness of the pick body is usually between 40-45 HRC, but this may vary on the application and standard produced to.
5.4 Can cutting picks be made based on the machine model?
Yes. Changing the shape of the pick, shank size, carbide tip size, material and hardness are some of the ways to customize the pick to fit the machine model and working conditions.
5.5 How can I select the right mining cutting pick?
Rock hardness, coal seam conditions, model of cutting equipment, shank size, cutter head structure should all be considered when selecting the right mining cutting pick. You should also have an idea of the wear resistance you need.
