Grid Pattern Holes: Plate Thickness 50-200mm

Component Specifications

Definition

A work surface plate component featuring a precisely machined grid pattern of threaded or plain holes arranged in uniform rows and columns, designed to provide flexible, repeatable mounting points for fixtures, clamps, gauges, and tooling in machining, assembly, and inspection operations.

Working Principle

Utilizes a standardized grid layout to enable modular fixturing, allowing components to be quickly positioned and secured at precise locations without custom tooling, enhancing setup efficiency and repeatability.

Materials

Cast iron (Grade 250-300), granite, or steel, often surface-treated (e.g., black oxide, nickel plating) for corrosion resistance and durability.

Frequently Asked Questions

What are the benefits of using grid pattern holes on work surface plates?

They provide flexible, repeatable positioning for fixtures, reduce setup time, eliminate custom tooling, and enhance accuracy in machining and inspection.

How are grid pattern holes typically manufactured?

They are precision-machined using CNC drilling or milling, with threads tapped to specifications, ensuring hole alignment and dimensional accuracy per standards like ISO 8512.

Can grid pattern holes be retrofitted to existing plates?

Yes, but it requires precise machining to maintain grid accuracy; new plates are recommended for critical applications to ensure flatness and hole consistency.
