What Can This CNC Sink Cutout Machine Do?
Automated Sink Cutouts: Processes undermount, top-mount and customized sink openings in granite, quartz, marble and other compatible stone materials.
Countertop Profiling: Supports edge profiling and customized countertop shapes without transferring the slab to another machine.
Drilling & Milling: The CNC spindle can perform faucet holes, internal corner machining, grooves and other secondary operations.
Grinding & Polishing: Compatible tooling allows the machine to perform selected grinding and polishing operations after cutting.
Key Features for Countertop Fabrication
Automatic Tool Changer: The ATC system allows the machine to automatically switch between cutting, milling, grinding and polishing tools, reducing manual tool changes and setup time.
Vacuum Positioning Table: Vacuum positioning helps secure the countertop during CNC machining and reduces movement during sink cutouts and profiling operations.
7.5 kW CNC Spindle: The 7.5 kW spindle operates from 0–8000 rpm, providing the cutting and milling capability required for common countertop fabrication operations.
Heavy-Duty CNC Structure: The machine uses a rigid steel structure designed for stable movement and continuous stone processing in professional fabrication environments.
