YM-1A Metallographic Sample Pre-grinder

‌YM-1A Automatic Abrasive System: The Smart Start to Metallographic Polishing‌

Why waste hours prepping samples manually? The YM-1A automates the critical first step of metallographic polishing with its ‌vacuum-lock abrasive system‌ and precision 700 RPM grinding. Designed to work seamlessly with automatic polishers, this compact powerhouse (650×340×300mm) ensures your samples are perfectly flat, scratch-free, and ready for final polishing – no adhesives, no guesswork.

‌Key Features‌

• ‌Hands-Free Abrasive Lock‌: Centrifugal vacuum tech grips 230mm abrasive paper instantly – zero glue, zero cleanup.
• ‌Polishing-Ready Surfaces‌: 700 RPM motor removes material evenly, reducing final polishing time by 40%.
• ‌Built for Automation‌: Compatible with robotic arms or conveyor systems for fully automated labs.
• ‌Industrial Durability‌: 36kg steel-frame construction handles 24/7 operation without vibration.
• ‌Water-Cooled Grinding‌: Prevents overheating and extends abrasive disc life.

During the metallographic sample preparation, pre-grinding is the essential former procedure before polishing. The pre-grinding enhances greatly the efficiency of the sample preparation. YM-1A is designed according to the customers’ requests and adapted to various kinds of materials. The size of the disc and the transmission power are larger than the same products in the market, which is the ideal equipment for pre-grinding. Working principle: the water flows into the rotating grinding disc through the water tube, and then the water below the abrasive paper flows out under the centrifugal force of the rotating disk, which generates a vacuum space and presses the abrasive paper on the disc tightly to do the pre-grinding work. When the disc stops rotating, the effect disappears and the abrasive paper can be easily taken off.
