Double-Blade Automatic and Automatic Gantry-Fixed Edge Trimming Machine for Stone Edge Cutting

The SHKB-21500 is a gantry-fixed, trolley-moving, double-blade edge trimmer driven by full-electric microcomputer control. Steel-wire rope transmission eliminates blade jamming under overload, delivering higher cutting efficiency, superior flatness, and longer blade life while reducing labor and energy costs. Ideal for edge cutting and chamfering of marble, granite, arc kerbstones, and tombstones.

• The one-touch program stores edge length, chamfer angle and feed rate
• No hydraulics → cleaner workshop
• Remote diagnostic port for on-line support

• 15 m effective travel (extendable) → single-pass trimming of long kerbs or tombstone borders
• The gantry frame absorbs vibration
• Open front & rear → forklift loading, automatic in-line connection to polishing line

• The overload slip protects blades from jamming when hitting hard veins
