CNC Stone Cutting and Milling Advantages
Cutting and Milling in One Machine
The main advantage of HD-350P is the combination of CNC stone cutting and independent milling.
A conventional stone cutting machine is primarily used to cut slabs into required dimensions. HD-350P adds an independent milling head for compatible secondary operations such as sink openings, faucet holes, drilling and milling.
For countertop manufacturers, this integrated configuration can reduce unnecessary slab transfers between separate cutting and machining equipment.
The machine can therefore support a workflow such as:
Cutting → Opening → Drilling → Milling → Finished Component
Designed for Countertop Fabrication
Countertop production often involves more than simply cutting a slab.
A typical kitchen countertop may require:
- Slab sizing
- Sink cutout
- Faucet hole
- Drain hole
- Additional milling
- Optional bevel cutting
HD-350P is designed around this type of fabrication workflow.
The independent milling head expands the machine’s capabilities beyond standard slab cutting, making it particularly suitable for:
- Kitchen countertops
- Bathroom vanity tops
- Quartz worktops
- Granite countertops
- Marble countertops
- Quartzite surfaces
- Customized stone components
Stable Cutting and Flexible Slab Handling
HD-350P uses a rigid machine structure to provide stable support for the cutting system during operation.
The hydraulic worktable can tilt from 0° to 85°, helping operators load, position and handle large stone slabs more efficiently.
The cutting head provides 0–90° rotation, while the optional 45° bevel cutting configuration allows the machine to address additional angled-cutting requirements.
The combination provides a flexible working platform for different stone fabrication tasks.
Efficient CNC Production
The CNC control system allows operators to program cutting dimensions and manage automatic cutting cycles.
Depending on the selected configuration, operators can manage:
- Cutting parameters
- Automatic cutting
- Manual positioning
- Position adjustment
- Quantity settings
- Program operation
- Cutting-cycle management
- Emergency stop and recovery functions
For repeated production, CNC-controlled movement helps reduce repetitive manual positioning and maintain more consistent dimensions between components.
Independent Milling Head for Stone Fabrication
The independent milling head is the key feature that differentiates HD-350P from a standard 3-axis Stone Cutting Machine.
During countertop production, the slab may require several additional machining operations after the primary cut.
HD-350P can be configured for suitable operations including:
- Sink cutouts
- Faucet holes
- Drain holes
- Round openings
- Oval openings
- Rectangular openings
- Drilling
- Local milling
- Selected profiling
The actual machining capability depends on the material, tooling, dimensions and selected machine configuration.
CNC Sink Cutout Processing
Sink openings are one of the most common machining requirements in countertop fabrication.
HD-350P uses its independent milling system for programmed sink-opening operations.
Depending on the selected tooling and production requirements, the machine can process suitable:
- Rectangular sink openings
- Round sink openings
- Oval sink openings
- Customized opening shapes
Integrating cutting and milling capabilities can reduce the need to move heavy slabs between separate machines for compatible operations.
Countertop Drilling and Hole Milling
Kitchen countertops and bathroom vanity tops frequently require holes for faucets, drains and other fixtures.
The independent milling head can perform suitable drilling and milling operations according to the material and tooling configuration.
Typical applications include:
- Faucet holes
- Drain holes
- Fixture holes
- Small circular openings
- Customized countertop holes
This makes HD-350P particularly useful for fabricators producing customized countertops and vanity tops.
CNC 3-Axis Stone Cutting System
The primary cutting system uses three CNC-controlled axes.
| Axis |
Main Function |
| X Axis |
Left-right movement across the working area |
| Y Axis |
Front-back movement across the slab |
| Z Axis |
Vertical movement of the cutting head |
The CNC system allows cutting dimensions and production parameters to be programmed for repeatable slab processing.
This is particularly useful for fabricators producing multiple countertops, worktops or repeated stone components.
Hydraulic Tilting Worktable
The HD-350P worktable can tilt from 0° to 85°.
The hydraulic tilting function helps operators load and position large-format slabs more efficiently.
It can be particularly useful when processing:
- Large marble slabs
- Granite slabs
- Quartz countertops
- Quartzite
- Porcelain slabs
- Sintered stone
The controlled table movement provides a practical solution for handling heavy stone slabs during production setup.
0–90° CNC Cutting Head Rotation
The cutting head supports rotation from 0° to 90°, providing flexibility for different cutting orientations.
Combined with CNC-controlled X/Y/Z movement, the rotating head supports standard cutting operations and selected angled cutting applications according to the machine configuration.
Optional 45° Bevel Cutting
HD-350P can be configured with an optional 45° bevel cutting function.
This feature is useful for countertop and architectural applications requiring angled edges or selected miter-related fabrication.
Typical applications include:
- Countertop edge preparation
- Angled stone components
- Architectural stone details
- Selected miter fabrication
The final cutting capability should be confirmed according to the required material, blade and machine configuration.
CNC Control for Automatic Stone Cutting
HD-350P is designed around a CNC-controlled production workflow.
Operators can enter cutting dimensions and manage automatic production through the machine control interface.
Typical functions include:
- Cutting parameter input
- Automatic cutting
- Manual positioning
- Position adjustment
- Program operation
- Quantity adjustment
- Cutting-cycle management
- Emergency stop and recovery
This allows the machine to support both customized fabrication and repeated production.
Touchscreen CNC Control Interface
The control system combines a touchscreen interface with physical controls.
The interface provides access to common machine functions while keeping daily operation straightforward.
Typical controls include:
- CNC program operation
- Cutting parameter input
- Manual movement
- Position adjustment
- Automatic cutting
- Machine status
- Emergency stop
The final control-system configuration may vary according to the machine specification and customer requirements.

The 3+1 axis configuration means:
3 = X / Y / Z CNC cutting axes
+1 = Independent milling head
The independent milling head expands the machine’s fabrication capability without changing the primary 3-axis cutting configuration.
This makes HD-350P a practical solution for applications requiring:
CNC Stone Cutting + Sink Cutouts + Drilling + Milling
HD-350P Stone Fabrication Workflow
Step 1 — Slab Loading
Load the stone slab onto the hydraulic worktable.
Step 2 — Positioning

It is particularly suitable for businesses that need CNC stone cutting and secondary milling operations within the same production workflow.
Why Choose HD-350P CNC Stone Cutting Machine?
For many stone fabricators, cutting a slab to size is only one part of the production process.
A finished countertop may also require sink openings, faucet holes, drain holes or additional machining.
The HD-350P addresses this workflow by combining a CNC Stone Cutting Machine with an independent milling head.
This provides a practical combination of:
Cutting + Drilling + Sink Openings + Milling + Countertop Fabrication
For customers who mainly need standard slab cutting, the HD-350T may be the more focused option.
For customers requiring additional cutting-axis capability together with milling, the HD-350M or HD-500M may be more suitable.
