Do you know the characteristics of rotary picks?
2022/08/26
Strictly optimized geometry allows the picks to be subjected to uniform stress during machining, cutting smoothly, making the wear level as uniform as possible, and further improving the working efficiency of the picks, wearing the helical teeth and reducing damage , to improve the reliability of the rotary cutting pick.
Using ultra-coarse and low-pressure sintered cemented carbide, the local welding of the rotary pick can withstand the super-hard wear layer, improve the wear resistance and impact toughness of the rotary pick, and prematurely crush the cemented carbide and spiral. Effectively avoid wear and tear, greatly extending the service life.
The precise manufacture and precise mixing between the tooth holder and the rotary pick ensures that the helical teeth can rotate freely in the corresponding tooth holder, rotating the evenly distributed blade grooves, accelerating the rotation of the tooth body and avoiding uneven belt wear.
As the tooth material of the rotary pick, the 42CrMo alloy structural steel with excellent forging performance is selected. The risk of temper embrittlement is eliminated through strict heat treatment, and the fatigue strength and impact resistance of the tower are significantly improved.
The unique self-polishing blade function ensures that the saber teeth are always clear, which improves the construction efficiency.
Every user not only considers price when buying a rotary pick cutter, but also pays attention to quality and hopes that the results produced in this way will be effectively reduced.
The main types of failures of rotary picks for turning drills are blade drop, cutting, wear and, in some cases, frequent failures of helical picks due to breakage.
The brazing and heat treatment technology of the rotary pick is one of the important technologies to ensure the quality of the helical pick. Currently, spiral welding and heat treatment are integrated technologies. By heating using a vacuum furnace and directly quenching the welded spiral without air cooling, the welding and heat treatment are completed immediately.
The manufacturing process strictly follows the design requirements to ensure that the rotary cutting pick is aligned with the tooth seat, to ensure that the tool rotates freely on the tooth seat, and to avoid uneven wear. It features automatic sharpening, the blade remains sharp, and the cutting teeth wear evenly and normally. and in a cutting state.
