Twin Wheel Metallographic Grinder & Polisher ToronPol™ - 202D/252D/302D Series - With Individual Wheel Speeds

The ToronPol™-202D/252D/302D Series is engineered to provide the ultimate in manual preparation flexibility and workflow optimization. Its defining feature is the independent, variable speed control for each wheel, allowing two completely different preparation steps—such as high-speed coarse grinding and low-speed final polishing—to be performed simultaneously. This makes it an ideal solution for dynamic labs that require maximum versatility from a single machine.

This advanced control is especially critical for efficiency and precision in:

• Materials Research & Method Development: For labs creating preparation procedures for new or exotic materials, allowing for the side-by-side comparison of different speeds and consumables to rapidly determine the optimal process parameters.
• Failure Analysis: To enable the meticulous, parallel preparation of different sections of a failed component, where a delicate fracture surface may require low-speed polishing while a larger section is simultaneously ground at high speed.
• High-Mix Quality Control: In job shops and commercial testing labs that handle a wide variety of materials daily, this system allows an operator to work on a soft metal (like aluminum) and a hard alloy (like tool steel) at the same time, each at its ideal speed.
• Process Engineering (Welding & Heat Treat): For quickly comparing the effects of different process variables by having one wheel set up for a standard preparation routine and the other for a specialized step, such as a final polish to reveal a specific microstructural feature.
