Holder Body/Base: Flatness 0.005 mm/100 mm

Component Specifications

Definition

The Holder Body/Base is a precision-engineered structural component designed as the foundational element of blade holder systems in industrial cutting and machining equipment. It serves as the primary mounting interface between the blade holder assembly and the machine tool, ensuring precise alignment, dimensional stability, and secure fixation of cutting blades during operation. This component typically features precisely machined surfaces, mounting holes, alignment features, and structural reinforcement to withstand cutting forces, vibrations, and thermal variations while maintaining positional accuracy.

Working Principle

The Holder Body/Base operates on mechanical fixation and structural support principles. It provides a rigid foundation that maintains geometric relationships between the blade, holder assembly, and machine tool through precision mounting surfaces and alignment features. During operation, it transfers cutting forces from the blade to the machine structure while minimizing deflection and vibration through optimized material distribution and reinforcement design.

Materials

Typically manufactured from high-strength alloy steels (AISI 4140, 4340), tool steels (D2, A2), or stainless steels (304, 316) with hardness ranging from 30-55 HRC depending on application requirements. Advanced applications may use engineered composites or aluminum alloys with steel inserts for weight reduction.
