Product Description
SZGH-650D CNC Milling Machine
Product Introduction
The SZGH-650D CNC Milling Machine is a high-speed, high-rigidity CNC machining solution designed for processing copper, iron, aluminum, and stainless steel components within a 600 × 500 mm working area.
Featuring a 7.5 kW electric spindle, BT30 spindle taper, maximum spindle speed of 24,000 rpm, and 12-tool magazine, the SZGH-650D is designed to handle milling, drilling, tapping, engraving, and other machining operations in a single CNC platform.
Compared with smaller CNC milling machines, the SZGH-650D provides a larger working area and longer X/Y/Z travels while maintaining a relatively compact machine configuration. Its effective travels are 500 mm on X-axis, 600 mm on Y-axis, and 300 mm on Z-axis, providing additional machining space for larger components.
The machine is also designed with a 1,800 kg heavy-duty anti-deformation patented base, helping provide the rigidity and stability required for high-speed machining.
Key Features of SZGH-650D
1. 600 × 500 mm Effective Working Area
The SZGH-650D provides an effective working surface of 600 × 500 mm, making it suitable for workpieces that require more machining space than the SZGH-540D platform.
The machine provides:
- X-axis travel: 500 mm
- Y-axis travel: 600 mm
- Z-axis travel: 300 mm
The spindle-to-table distance ranges from 150 mm to 450 mm, according to the product specification.
This configuration provides additional flexibility for machining components with larger dimensions or more complex geometries.
2. 7.5 kW High-Speed Electric Spindle
The SZGH-650D is equipped with a 7.5 kW electric spindle and a BT30 spindle taper.
Its maximum spindle speed reaches 24,000 rpm, supporting high-speed machining applications that require rapid spindle rotation.
The catalog lists the spindle configuration as:
Electric spindle | 7.5 kW | BT30 | up to 24,000 rpm.
The high-speed spindle configuration makes the machine suitable for applications involving smaller cutting tools, high-speed milling, drilling, engraving, and other precision machining processes.
3. 12-Tool Automatic Tool Magazine
The SZGH-650D is equipped with a 12-tool magazine.
Compared with an 8-tool configuration, the additional tool capacity allows more machining operations to be prepared within a single machining cycle.
A typical production sequence may include:
- Face milling
- Side milling
- Drilling
- Tapping
- Slot milling
- Contouring
- Engraving
The actual tool configuration should be confirmed according to the final machine configuration and production requirements.
The product catalog specifies a 12-handle/tool magazine for the SZGH-650D.
4. Heavy-Duty Anti-Deformation Base
The SZGH-650D adopts an 1,800 kg heavy-duty anti-deformation patented base.
A rigid machine foundation helps support stable movement of the machining head and reduce vibration during machining.
According to the catalog, the product features include:
- A heavy-duty anti-deformation patented base designed to support high-speed and stable movement.
- Sufficient machine weight to support anti-vibration performance.
- High-quality wear-resistant components.
- Dynamically balanced spindle installation.
- SZGH electric control package for coordinated electromechanical performance.
For customers machining stainless steel and other demanding materials, machine rigidity is an important consideration because cutting stability can directly affect surface quality, tool life, and machining consistency.
5. High Rigidity for Metal Machining
The SZGH-650D is designed around a high-rigidity and anti-deformation structure.
The machine uses:
- 32 mm precision P-grade screw
- 30 mm Precision C3 Grade guide rail
- 1,800 kg heavy-duty anti-deformation base
- 7.5 kW electric spindle
- SZGH CNC control
- SZGH feed servo system
These specifications are listed in the product catalog.
This configuration makes the SZGH-650D particularly relevant to manufacturers that require stable multi-process machining rather than basic light-duty milling.
6. Multi-Process CNC Machining
The SZGH-650D is not limited to milling.
The product description specifies support for:
Milling + Drilling + Tapping + Engraving + Other CNC machining operations
This multi-process capability allows manufacturers to complete multiple operations on one CNC machine.
The catalog specifically states that the machine is compatible with general machining centers and supports drilling, tapping, milling, engraving, and other functions.

SZGH-650D Machining Capacity
The SZGH-650D is designed to process several commonly used engineering materials.
Aluminum Machining
The machine supports aluminum machining with a listed maximum drilling diameter of Ø35 mm under the standard value and Ø40 mm under the maximum value, depending on configuration and machining conditions.
The maximum tapping capacity is listed as M25 for aluminum.
Steel Machining
For steel workpieces, the catalog specifies:
- Standard maximum drilling diameter: Ø30 mm
- Maximum drilling diameter: Ø35 mm
- Standard tapping: M18
- Maximum tapping: M20
Actual machining capacity should be determined according to the material grade, cutting tool, cutting parameters, and workpiece geometry.
Stainless Steel Machining
Stainless steel is explicitly included within the SZGH-650D application scope.
The catalog describes applications for stainless steel parts involving tapping within 30 mm and drilling within 20 mm under the stated application conditions.
Because the catalog's general processing-capacity table and application description use different operating conditions, the final drilling and tapping parameters should be confirmed with SZGH according to the customer's actual stainless steel application.
