HWJ-4020P AC Five Axis Waterjet Machine
Product features
-
-
Unmatched Design Freedom & Complex 3D Capability: Creates intricate shapes, deep contours, compound curves, undercuts, and detailed sculptures impossible with saws or 3-axis machines (e.g., complex sink bowls, ornate columns, flowing countertop edges, bespoke art pieces).
-
Perfectly Square Edges & Miters (Taper Elimination): Dynamically tilts the cutting head to compensate for the natural waterjet taper ("kerf angle") as it cuts through thick stone. This results in:
-
True 90-degree edges on slabs (critical for seamless joins).
-
Precise miter cuts for perfect corner joints without gaps.
-
Significantly reduced need for secondary edge finishing.
-
-
Superior Edge Quality: Produces smooth, clean cuts directly from the machine, often requiring minimal or no additional sanding or polishing, saving time and labor costs.
-
Cold Cutting Process (No Heat-Affected Zone - HAZ): Uses ultra-high-pressure water and abrasive, generating no heat. This:
-
Prevents cracking, chipping, or thermal stress in sensitive stones like marble or quartzite.
-
Avoids altering the stone's inherent structure or color near the cut line.
-
Eliminates the risk of warping.
-
-
Minimal Material Stress & Vibration: The non-contact cutting process applies very little mechanical force or vibration to the stone, protecting fragile materials and ensuring dimensional accuracy.
-
Versatility Across Stone Types & Thicknesses: Effectively cuts virtually any natural or engineered stone (granite, marble, quartz, onyx, limestone, slate, etc.), regardless of hardness or brittleness, and handles a wide range of thicknesses on a single machine.
-
Reduced Waste & Optimized Material Usage: Advanced nesting software allows for highly efficient arrangement of complex parts on a stone slab, minimizing scrap and maximizing yield.
-
No Tool Wear Changes Cut (Unlike Saws): The cutting "tool" is a stream of water and abrasive. There are no physical blades to wear down or become dull, ensuring consistent cut quality and kerf width from the first cut to the last on a project.
-
Single Setup for Complex Parts: Often, highly complex 3D shapes can be cut complete in a single setup, reducing handling time, potential for damage, and alignment errors compared to multi-step processes.
-
Enables Innovative Architectural & Artistic Applications: Opens doors for designers, architects, and artists to realize previously impossible or prohibitively expensive concepts in stone, pushing the boundaries of the material.
