Robbins Cutters

Robbins designs and manufactures the most technically advamced disc cutters worldwide with a commitment to high quality and continual improvement. No matter the geology, no matter the machine type or manufacturer, no amtter the size- Robbins has the cutting solution to meet your needs.

DISC RINGS
Robbins disc rings are composed of proprietary tool steel produced in Germany to Robbins specifications. The steel manufacturing processes are designed to keep impurities to a minimum. Melting in an Electric Arc Furnace is followed by vacuum degassing. Ingot molds are filled from the bottom with the liquid steel shrouded in argon gas. Exceptionally clean steel ensures high resistance to fatigue, resulting in longer cutter disc life.

Forgings are made by the closed die method in Germany. Subsequent processing consisting of two machining steps and four heat treatment steps are completed in the USA.

BEARINGS
Carburized and case-hardened, Robbins uses Tim ken tapered roller bearings that outperform other bearings in dynamically loaded conditions and harsh environments. During assembly, the bearings are pre-loaded to effectively excavate hard rock in the most severe operating conditions.

SEALS
Durable metal-to-metal face seals eliminate ingress of foreign materials while silicone torics maintain elasticity even at high temperatures.

PRESSURE COMPENSATION RETAINER
The patented Robbins pressure compensation retainer has a superior piston design with a much larger surface area than other cutter manufacturers. The outer surfaces are carburized and case-hardened for extended life in harsh conditions.
