The HMS-1800 electric lifting radial arm polishing stone machine is a semi-manual radial arm polishing device. It is designed by Hualong Company specifically for small and medium-sized stone processing workshops. Equipped with an electric vertical lifting system and a pneumatic pressure cylinder, it can grind and polish granite, marble, quartz slabs, tombstones, and mosaic tiles. The HMS-1800 supports grinding and polishing slabs with thicknesses from 10mm to 400mm.

Main Features：

1. Manual Swing Arm and Electric Lift
This model features an electric lift design. The overall lifting operation is smooth and easier to maintain than hydraulic systems, with no risk of oil leaks. The swing arm supports 360° free rotation and can be manually pushed or semi-automatically moved, making it suitable for processing irregular or oddly shaped panels.

2. Equipped with a Pneumatic Pressure Polishing System
The cylinder provides continuous, stable pressure to the grinding disc. The even polishing pressure helps ensure a glossy surface on the panel. This avoids the uneven pressure and ripples or color differences caused by manual polishing.

3. Wide Range of Applications
It can be used for processing tombstones, small stone panels, mosaics, and other materials with frequently changing thicknesses. Compatible stone types include granite, marble, quartz, and more. It can handle stone thickness from 10–400mm, so the equipment doesn't need constant adjustment.

4. Easy to Operate and Learn
Even beginners can quickly learn how to operate this stone polishing machine. The grinding disc connectors are standardized, allowing fast swapping of grinding heads or discs, reducing downtime.

5. High Cost Performance
This is a mid-range semi-automatic model. Its price is much lower than fully automatic continuous polishing lines. Compared to fully manual polishing machines, it offers higher automation and stability.
