ROCKSHARP HD-SP
45° Horizontal Intelligent Polishing Machine
Designed specifically to meet the growing demand for edge finishing of slabs, this machine is particularly suitable for chamfering and grooving sintered stone. It efficiently and precisely performs 45° chamfering and seamless joint finishing on slabs of various sizes and thicknesses. Equipped with a high-power brand motor, 300mm blades, pneumatic clamping device, and front and rear synchronous feeding belts, the machine ensures stable material transport, easy operation, and consistent processing results even on large slabs.
Types of stone that can be processed
The HD-SP Intelligent Stone Edge Polishing Machine is suitable for processing marble, granite, quartz stone, engineered quartz, sintered stone, porcelain slabs, and other stone materials. It is widely used for edge finishing and polishing of kitchen countertops, vanity tops, island tops, tabletops, coffee tables, TV cabinet tops, reception counters, service desks, and other custom stone products, delivering high-quality edges and consistent polishing results.
