One CNC Platform for Different Stone Jobs
Stone fabrication orders are rarely limited to one cutting pattern. A production machine needs to handle different shapes, angles, and secondary operations without creating unnecessary setup work.
The HKNC-450PLUS integrates:
- CNC stone cutting
- Multi-angle and bevel cutting
- Drilling
- Milling
- Profiling and shaping
5-Axis Movement for Complex Cutting
The cutting head provides 0–360° rotation, while the blade can tilt from 0–90°.This movement configuration allows the machine to handle:
Straight cutting: For standard marble, granite, quartz and engineered-stone slabs.
Bevel cutting: For angled edges and miter-related stone fabrication.
Shaped cutting: For customized profiles and non-standard stone components.
Secondary machining: For drilling, milling and profiling where additional machining is required.

Target Applications & Finished Products
Residential Kitchen Countertops: Straight cuts, sink cutouts, edge beveling, and cooktop openings.
Bathroom Vanity Tops: Precision basin plunge milling, splashback slicing, and faucet hole drilling.
Stairs & Window Sills: Beveled stair treads, risers, and decorative window sill profiles.
Commercial Tile Sizing: Fast batch slicing of granite, quartz, and marble floor cladding.

FAQ
Q: What secondary operations can it perform?
A: The machine supports drilling, milling and profiling in addition to stone cutting.
Q: How does this machine handle undermount sink cutouts?
A: After completing the outer rectangle/arc cuts with the saw blade, the machine automatically switches to a diamond finger bit mounted on the spindle nose to plunge-mill the internal sink corners and smooth out the edges – all in one setup, without repositioning the slab.
Q: What is the main difference between this model and a dedicated 3D CNC stone engraving center?
A: This machine is optimized for high-speed slab processing, cutting, and standard countertop milling. For deep artistic 3D bas-relief sculpting or complex stone column carving, we recommend a heavy 3D CNC carving center instead.
Q: What is the typical production lead time?
A: The standard lead time is approximately 30 days after deposit, subject to the selected configuration and production schedule.
Q: What payment methods do you accept?
A: We accept T/T (Telegraphic Transfer) for international orders. The payment schedule and required deposit are confirmed in the commercial quotation and sales contract before production starts.
