Horizontal Stone Chamfering & Polishing Machine
The Horizontal Stone Chamfering & Polishing Machine WSDJ-4C is specially designed for automatic 45° back chamfering and polishing of granite, marble, and sintered stone slabs.
Adopting a horizontal belt feeding structure, this machine is widely used for edge processing of kitchen countertops, stair treads, threshold stones, and other stone products. The feeding speed can be adjusted according to different materials, while the chamfering width and angle can be precisely controlled.
With a combination of rough grinding and fine grinding processes, the machine ensures smooth and uniform chamfering results with less chipping. It is an ideal solution for high-efficiency mass production and can be integrated into automatic stone slab processing lines.
