YM-1A Single-Disc Pre-Grinder – The 1-Minute Starter for Flawless Polishing‌
‌Polishing starts with perfect pre-grinding. The YM-1A’s ‌water vacuum system‌ grips abrasive paper in seconds – no clamps, no adhesives, no cleanup. At ‌700 RPM‌, it removes deep scratches from steel, alloys, or ceramics faster than hand grinding. Need to switch grits? Just stop the disc – the paper pops off dry. With a ‌36kg lightweight frame‌ and ‌380V industrial power‌, it’s the plug-and-play solution for labs that hate downtime.

‌Key Features ‌

‌Water-Powered Grip‌: No glue residue – water creates vacuum adhesion.
‌700 RPM Speed‌: Rough to fine grinding in one machine.
‌Instant Paper Swaps‌: Change discs faster than brewing coffee.
‌Stainless Steel Body‌: Survives daily splashes and harsh labs.
‌Space Saver‌: 650×340mm footprint – fits on crowded benches.

‌Technical Specs ‌

Parameter	Details
Disc Diameter	230mm (Standard size for easy sourcing)
Speed	700 RPM (Optimized for quick material removal)
Motor	YS7118, 0.2kW, 380V, 50Hz
Dimensions	650×340×300mm (Smaller than a microwave)
Weight	36kg (Move it solo – no cart needed)

‌Why YM-1A Stands Out‌

‌No Adhesive Costs‌: Competitors waste $200+/year on glue – the YM-1A uses free water.
‌Beginner-Friendly‌: Lab interns master it in 2 minutes.
‌Energy Efficient‌: 0.2kW motor cuts power bills vs. heavy grinders.

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.
