Cutting Teeth/Picks Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

Cutting teeth, also known as picks or bits, are precision-engineered cutting components designed for attachment to rotating cutter heads in industrial equipment. These components feature hardened cutting edges or tips that engage with workpieces to perform cutting, milling, drilling, or material removal operations through mechanical shearing, abrasion, or impact mechanisms. They are critical wear parts in continuous material processing systems.

Working Principle

Cutting teeth/picks operate on the principle of concentrated force application through hardened cutting edges or tips. When mounted on a rotating cutter head, they engage with the workpiece material, creating localized stress concentrations that exceed the material's shear strength. This causes material separation through shearing, chipping, or fracturing. The geometry, material composition, and mounting angle determine cutting efficiency, chip formation, and tool life.

Materials

Tungsten carbide tips brazed to alloy steel shanks (most common), polycrystalline diamond (PCD) tips for abrasive materials, ceramic composites for high-temperature applications, hardened tool steel for general purpose cutting. Shank materials typically include 42CrMo, 35CrMo, or similar alloy steels with heat treatment to 40-45 HRC.

Frequently Asked Questions

What is the typical service life of cutting teeth/picks?

Service life varies from 50-500 operating hours depending on material hardness, cutting conditions, and tooth quality. Tungsten carbide teeth typically last 100-300 hours in medium-hard materials.

How often should cutting teeth be replaced?

Replace when wear exceeds 30% of original tip dimensions or when cutting efficiency drops by 20%. Regular inspection every 8-24 operating hours is recommended.

Can different brand cutting teeth be mixed on the same cutter head?

Not recommended. Mixing brands can cause imbalance, uneven wear, and reduced cutting efficiency due to dimensional and material variations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
