Main Body/Plate: Thickness 15-50 mm, Surface finish Ra 1.6 μm

Component Specifications

Definition

The Main Body/Plate is the primary structural component of a cutter head assembly in industrial cutting machinery. It serves as the foundation for mounting cutting blades, knives, or other cutting elements, ensuring precise alignment and stability during operation. This component distributes cutting forces evenly, maintains geometric accuracy, and provides attachment points for drive mechanisms and safety guards.

Working Principle

The plate functions as a rigid mounting platform that transfers rotational or linear motion from the drive system to cutting tools while maintaining dimensional stability under operational loads. It ensures consistent cutting geometry by preventing deflection and vibration during material processing.

Materials

High-strength alloy steel (AISI 4140/4340), hardened to 45-55 HRC, or tool steel (D2, M2) with corrosion-resistant coatings where required.
