HHIP 4406-1212 Cast Iron Hand Scraped Surface Plate, Grade 11 Flatness, 8 Microns, 12″ Length X 12″ Width X 2″ Thick

Description

Product Overview

The HHIP 4406-1212 cast iron hand scraped surface plate is engineered to meet the demanding requirements of precision metrology in modern manufacturing environments. Constructed from close‑grained cast iron that has been stress relieved, the plate undergoes a meticulous hand‑scraping process followed by precision grinding to achieve a flatness tolerance of Grade 11, which corresponds to a maximum deviation of 8 microns across the entire surface. Measuring 12 x 12 x 2 inches and weighing approximately 37 pounds, this plate offers a substantial mass that contributes to its inherent stability and resistance to vibration during critical measurement tasks. The surface is finished to a smooth, matte texture that readily accepts magnetic bases, allowing users to securely attach accessories such as magnetic gauge blocks, dial indicators, and other inspection tools. The robust construction ensures long‑term durability, making it suitable for continuous use in tool rooms, calibration labs, and production lines where repeatable accuracy is essential.

Usage

This surface plate is versatile across a wide range of industrial applications. In tool and die making, it provides a stable reference plane for setting up grinding operations, aligning workpieces, and verifying the geometry of cutting tools. Quality control engineers rely on the plate for dimensional inspection of machined components, using it as a base for height gauges, coordinate measuring machines (CMMs), and surface roughness testers. The plate’s magnetic compatibility enables quick attachment of magnetic bases, facilitating rapid setup changes and reducing downtime. It is also valuable in research and development settings where prototype parts require precise flatness verification before moving to production. The plate can be employed in aerospace, automotive, and heavy equipment manufacturing where tight tolerances and repeatability are non‑negotiable. Its size makes it easy to integrate into existing workstations, and the 2‑inch thickness provides the necessary rigidity to support heavy gauge blocks without flexing.

FAQ

What does Grade 11 flatness mean?

Grade 11 flatness specifies that the surface deviation does not exceed 8 microns across the entire plate, which is suitable for high‑precision inspection and calibration tasks.

Can this plate be used with magnetic gauge blocks?

Yes, the plate’s surface is designed to hold magnetic bases securely, making it compatible with magnetic gauge blocks and other magnetic accessories.

How should the plate be maintained?

Keep the surface clean and free of debris, avoid dropping heavy objects onto it, and periodically check flatness with a calibrated reference to ensure continued accuracy.

Is the plate suitable for temperature‑controlled environments?

The cast iron material is stable under typical laboratory temperature ranges, but for the highest accuracy, it should be used in a temperature‑controlled environment as recommended by calibration standards.

What warranty does HHIP provide?

HHIP offers a limited warranty covering material defects for a specified period, along with access to technical support for installation and maintenance assistance.
