INDUSTRY COMPONENT

Support Block

A precision-machined block used in positioning fixtures to provide stable support and accurate height reference for workpieces during machining operations.

Component Specifications

Definition
A support block is a fundamental component in industrial positioning fixtures, designed to maintain consistent workpiece elevation and prevent deflection during machining, assembly, or inspection processes. These blocks are typically mounted to fixture bases and provide rigid, repeatable contact points that ensure dimensional accuracy across production batches.
Working Principle
The support block operates on the principle of rigid body support, creating stable datum points that counteract gravitational and machining forces. By maintaining precise height dimensions and flat contact surfaces, it ensures workpieces remain in the correct spatial orientation relative to cutting tools or measurement devices throughout the operation cycle.
Materials
Typically manufactured from hardened tool steel (A2, D2, or O1 grades), stainless steel (304 or 416), or aluminum alloy (6061-T6) with hardness ranging from 45-60 HRC for steel variants. Surface finishes of 0.8-1.6 μm Ra are standard for contact faces.
Technical Parameters
  • Flatness 0.005 mm
  • Mounting M6 or M8 threaded holes
  • Parallelism 0.01 mm/m
  • Load Capacity 500-5000 N depending on material
  • Standard Sizes 10x10mm to 100x100mm cross-section
  • Height Tolerance ±0.005 mm
Standards
ISO 9001, DIN 6325, ASME Y14.5
