Stainless Steel Sink Grinding Machine CNC Automatic Sink Edge Polishing Machine

Designed for high-precision production of stainless steel kitchen sink bowls, the Hwashi CNC Stainless Steel Kitchen Sink Bowl Making Machine integrates advanced computer numerical control (CNC) technology to deliver consistent, professional-grade results. Tailored for both small-batch customization and large-scale manufacturing, this machine excels in shaping 304/316 grade stainless steel— the preferred material for durable, corrosion-resistant sink bowls—with thicknesses ranging from 0.8mm to 3mm.
Its key features include a high-torque servo motor system that ensures smooth, vibration-free cutting and forming, eliminating uneven edges or surface blemishes common in manual processes. The intuitive CNC control panel allows operators to input custom sink bowl dimensions (e.g., depth, diameter, corner radius) and save presets for repeated use, reducing setup time by up to 40%. Additionally, the machine is equipped with a multi-axis forming mechanism that adapts to various sink bowl styles, from deep single-bowl designs to shallow double-bowl configurations, meeting diverse market demands.
Safety and efficiency are prioritized: a built-in infrared safety barrier stops operation if hands or debris enter the working area, while an automatic lubrication system minimizes wear on moving parts, extending the machine’s service life. Compatible with standard industrial power supplies (380V/50Hz), it also includes a dust collection system to keep the workspace clean and comply with environmental standards. For manufacturers seeking to elevate sink production quality and speed, this Hwashi CNC machine is a reliable, future-ready investment.
Specifically engineered to meet the stringent standards of Italian-style kitchen sinks—known for their sleek, seamless aesthetics and robust construction—the Hwashi Automatic Seam Welding Machine revolutionizes the welding process for this high-end product category. It specializes in creating invisible, leak-proof seams on stainless steel Italian sinks, where even minor weld imperfections can compromise the sink’s premium look and functionality.
CNC Precision, Perfect Consistency
- Equipped with advanced computer numerical control (CNC) technology, the machine delivers exacting precision across every sink. From edge angles to surface smoothness, it eliminates human error, ensuring each unit meets strict quality standards – critical for luxury and commercial-grade sink production.
All-in-One Efficiency
- Seamlessly integrates grinding and polishing into a single workflow. The high-torque grinding module removes imperfections, burrs, and weld marks, while the automatic edge polisher creates mirror-like or satin finishes (adjustable to your specifications). Reduce production time by up to 50% compared to manual processes.
Versatility for Every Sink Design
- Adaptable to various sink shapes (undermount, drop-in, farmhouse), sizes, and thicknesses. Whether working with 304, 316, or other stainless steel grades, the machine’s customizable settings ensure optimal results for both standard and custom designs.
User-Friendly Operation
- Intuitive touchscreen interface allows operators to program sink specifications, save presets for recurring orders, and monitor progress in real time. Minimal training is required, reducing onboarding time and operational errors.
