Metallography Equipment Overview

Introduction

A metallography lab is a sequence of dependent steps: a poor cut limits what mounting can fix, a poor mount limits what grinding can fix, and so on down the line. Each stage of the workflow has its own equipment family, and within each family, the choice between manual, automated, pneumatic, hydraulic, or specialty systems comes down to sample volume, materials, and required precision.

This page walks the workflow stage by stage, showing the PACE Technologies equipment behind each step alongside the fundamentals that apply across the industry. Specific models and features vary by manufacturer; the equipment categories and their purposes do not.

Sectioning Equipment

Sectioning equipment is used to cut samples from larger workpieces. The type of sectioning equipment you need depends on the materials you work with, sample size requirements, and the level of precision needed.

Abrasive Cutters

Abrasive cutters use rotating abrasive wheels (typically aluminum oxide or silicon carbide) to cut through a wide range of materials and sizes. They are the most common choice for general metallographic work, faster and more cost-effective than precision wafering, though they generate more heat and may cause more deformation in soft or delicate materials.
