5 Axis CNC Machine for Stone Cutting | BCTC BHKNC 500PLUS
5 Axis CNC Machine
The BCTC BHKNC 500 PLUS is a 5 Axis CNC machine designed for stone fabrication applications. Mainly used for stone countertop processing factories and building special shaped parts processing workshops. Granite, marble, quartz, sintered rock, and ceramic slabs can all be processed.
The biggest difference compared to ordinary 3 axis or four axis bridge cutting is that the saw blade head can rotate 360 degrees and swing from 0 to 90 degrees. This means that chamfering, chamfering, slotting, drilling, and contouring are all completed in one clamping process. There is no need to move the board to another device or manually adjust the angle.
Core Value:
✓ 5 axis linkage supports oblique cutting, chamfering, miter cutting, and contour machining with fewer setup changes.
✓ 0–360° blade rotation and 0–90° blade tilt for flexible cutting directions and angles.
✓ Italian ESA CNC system for stable control, accurate motion, and remote diagnostic support.
✓ Pegasus CAD/CAM software for efficient programming, nesting, and simulation before cutting.
✓ 0–85° tilting worktable for easier slab loading, unloading, and angle processing.
✓ Suitable for granite, marble, quartz, sintered stone, and ceramic slabs.
Control System and Software
Core Highlights
The control part uses the Italian ESA system, equipped with a 19 inch touch screen. This system has a large installed capacity in the stone processing industry and is highly recognized for its stability in the industry.

19inch touch screen
A few functions that are truly useful in actual workshops:
Knife path preview: After the program is copied into the machine, the screen first traces the cutting path, and the operator can tell at a glance whether the cutting path exceeds the board surface or hits the fixture. Confirm that there are no issues before starting to cut. This feature is quite helpful for beginners.
Real time monitoring: During the cutting process, the screen displays the current coordinates, spindle load, and feed rate. Once the load exceeds the limit abnormally, the machine will automatically alarm and stop, while recording the breakpoint position. After handling the exception, you can continue from the breakpoint without starting from scratch.
USB drive import and export: Program transmission relies on USB flash drives and is not connected to the internet. Unstable network in the workshop environment is the norm, while USB drives are actually more reliable.
Remote diagnosis: The ESA system supports remote access for after sales service. After the problem occurs, the operator sends the alarm code and system log to the after sales service, and in most cases, it can be resolved remotely. From reporting to problem confirmation, it usually takes 1-4 hours to complete.The software comes with Pegasus CAD/CAM, which is also from Italy. Bundled with ESA system.
Nesting layout: Manual drag and drop layout is the main method, with automatic algorithm assistance. After selecting a camera system, the camera captures images of the board surface, and the software automatically identifies cracks, color spots, and gaps, avoiding these positions during layout. The photography and recognition process takes approximately 30 seconds to 1 minute to complete.
Knife path simulation: Run the complete cutting path on the computer first, confirm it is correct, and then export the G code. The simulation environment is consistent with the actual machine parameters, and the accuracy of the simulation results is close to 100%.
Difficulty in getting started: The interface menu has few layers, and the graphical guidance is relatively intuitive. People with experience in operating CNC bridge cutting or engraving machines can independently create programs within 1-2 days. A new employee with zero foundation can operate under the guidance of a master for a week.
Axis system and range of motion
X axis (horizontal movement of the bridge), Y axis (vertical movement of the tool holder), Z axis (lifting and lowering of the tool holder), A axis (inclination of the saw blade), and C axis (rotation of the saw blade).
C-axis
Continuous rotation from 0 to 360 degrees, without mechanical limit. That is to say, the saw blade can cut in any direction without the need for a U turn.
A-axis
Swing from 0 to 90 degrees. Control the angle between the saw blade and the board surface to achieve chamfering, oblique cutting, and V groove opening.
In actual processing, one positioning is used to complete straight cutting, 45 degree angle fitting, circular holes, elliptical holes, and irregular edges. No need for manual flipping or secondary knife alignment.
The workbench tilts from 0 to 85 degrees
The main two purposes are: firstly, to tilt the table during the loading and unloading of large boards, so that operators do not have to bend over; The second is to locate certain angles by directly using the table to find the angle, which is more accurate than manual marking.

What can BHKNC 500 PLUS 5 Axis CNC Machine actually do?
Applications
Kitchen countertops and washbasins: straight cut, sink holes, faucet holes, edge formed
Architectural stone: imitation of lines, column bases, and column caps.
Tombstone and fireplace: outer contour cutting, surface text carving (requires power distribution spindle).
Decorative relief: Equipped with a 5.5kW electric spindle, it can complete shallow relief and engraving.
The actual purpose of selecting accessories
Thickness probe
Contact sensors measure the actual thickness at several points along the surface of the board. The software automatically compensates for the Z axis feed depth based on the measured value. When encountering materials with uneven thickness, it is possible to ensure that the cutting is through but not to the pad.
Vacuum suction cup
After cutting is completed, the suction cup picks up the finished product from the table and places it on the unloading table. Reduce manual handling and avoid scratching the board surface. Thin and large boards have the most obvious effect. The suction force of the suction cup can be adjusted according to the weight of the board.
Photo kit
The industrial camera is mounted on the machine crossbeam, and after scanning the board surface, the software automatically corrects the lens distortion, generates the board surface contour and defect marks. The operator arranges the workpieces in the available area on the software, and the equipment automatically avoids the defect location.

Frequently Asked Questions
Q: What materials can be cut?
+
-
Granite, marble, quartz, sintered rock, ceramic slabs. Artificial stone and resin boards can also be cut, but the feed rate and cooling flow rate need to be adjusted according to the material.
Q: What is better about five axes than three axes?
+
-
The three-axis bridge cutting saw blade can only move up and down and forward and backward, and manual angle adjustment or moving the board to another device is required to make oblique edges or corners. All five axis clamping is completed in one go, saving time and avoiding errors in secondary positioning.
Q: Is it suitable to make a kitchen countertop?
+
-
Yes. Panel processing is the most typical usage scenario of this equipment - straight cutting, sink drilling, edge forming, 45 degree corner splicing, all solved in one workstation.-
