SZGH Precision milling Machine VMC Metal Machining Center Vertical CNC Milling Machine

1. VMC650 Milling Machine Core Positioning and Basic Parameters

The SZGH precision five-axis vertical CNC milling machine is a core device designed specifically for precision metal processing. It focuses on the integrated multi-step machining needs of small and medium-sized workpieces. With its high stability, high precision, and flexible adaptability, it is widely used in automotive parts, precision molds, aerospace components, medical devices, and other fields.

The basic specifications and core performance parameters of the VMC650 milling machine are as follows:

Processing travel: Adopting the standard VMC650 milling machine design, the X/Y/Z axis travel reaches 650 x 400 x 500 mm, respectively, covering the machining range of most small and medium-sized metal workpieces and adapting to diverse needs, from simple flat milling to complex curved surface machining.

Spindle system: Equipped with a 7.5 kW servo spindle motor and an SZGH10-2-35-5.5/7.5-4-1500 spindle servo unit, it delivers a stable output torque of 35 Nm, supports a maximum high-speed operation of 8000 rpm and a rated speed of 1500 rpm, balancing high-speed cutting efficiency with low-speed, heavy-load machining capabilities, easily handling the cutting needs of a variety of metal materials such as aluminum alloys, stainless steel, and titanium alloys.

Drive configuration: All three axes of X/Y/Z utilize SZGH130 servo motors, each with a drive power of 3.8 kW and an output torque of 15 Nm. Newton-meters, combined with a high-precision transmission structure, ensures smooth and responsive movement of each axis, reliably guaranteeing machining accuracy.

Tool Changing System: Equipped with an arm-type ATC-16 automatic tool changing system, it features fast tool changes and precise positioning, reducing waiting time during process switching, significantly improving batch processing efficiency, and meeting the needs of continuous multi-process production.

2. VMC Milling Machine Structural Design: Stability and Durability

To achieve long-term high-precision machining and low-failure operation, the machine's structural design has been optimized in multiple dimensions, focusing on stability, wear resistance, and vibration resistance from core components to the overall frame. Precision Connection and Lubrication Design: The VMC650 milling machine utilizes precision connections for key moving parts, coupled with a fully automatic lubrication system that intelligently replenishes lubricant based on the machine's operating status. This reduces friction between components, extends the service life of core components like the spindle and ball screw, and reduces the need for routine maintenance.

High-Precision Drive System: The X/Y/Z axes utilize high-quality ball screws with dedicated precision bearings. These ball screws offer minimal pitch error and high transmission efficiency, while the dedicated bearings provide excellent radial and axial stiffness. This combination effectively controls positioning errors (with micron-level accuracy), improves contour following performance, and avoids dimensional deviations caused by drive backlash during machining.

Strong Rigidity Frame Structure: The bed and columns, along with other major load-bearing components, are constructed from high-strength cast iron. A strategically designed internal rib layout reduces overall machine weight while significantly enhancing structural rigidity and vibration resistance—even at high spindle speeds (e.g., 8,000 rpm). This effectively suppresses vibration during high-speed machining (including high-speed cutting) or heavy-load cutting, preventing it from affecting surface finish and dimensional accuracy.

Low-noise, low-consumption spindle drive: The precision high-speed spindle unit and AC servo motor are driven by a synchronous belt. The belt's excellent elasticity and smooth transmission reduce vibration transmission during motor operation, lowering spindle operating noise (no-load noise ≤ 75 decibels). It also reduces spindle heat generation, preventing spindle deformation caused by elevated temperatures, and further ensuring stable machining accuracy.

3. Flexible Customization: The VMC650 milling machine can adapt to diverse machining needs.

To meet the personalized machining needs of customers in various industries, the machine offers a wealth of customization options, allowing for flexible adjustments from core components, performance parameters, to exterior features. These options include:

Core Component Options: Supports optional Taiwan-made spindles, ball screws, and precision bearings. Taiwanese components offer proven advantages in precision retention and durability, making them suitable for applications requiring the highest precision (such as precision mold cavity machining).

Guideway Upgrades: X/Y/Z-axis linear guides can be added. Compared to traditional sliding guides, linear guides offer lower friction, higher travel speeds, and better precision retention, further enhancing the machine's responsiveness and long-term machining stability.

Spindle Speed Boost: The default maximum speed is 8,000 rpm, which can be customized and upgraded to 10,000 rpm based on customer high-speed cutting requirements. The VMC650 milling machine is suitable for high-speed, low-force cutting of thin-walled parts and high-precision curved surfaces, minimizing workpiece deformation.

Operational Accessories: An optional portable handwheel allows operators to precisely control axis movement during manual adjustments and workpiece alignment, enhancing operational flexibility.

Appearance and Customization: The VMC650 milling machine supports OEM/ODM services, allowing customization of machine colors and logos based on customer branding requirements. It can also be adapted to different regional voltage standards (e.g., 110V, 220V, 380V, etc.) to meet the needs of diverse global markets.

4. Milling Controller: Intelligent and Precise Control Core

The machine is equipped with the SZGH three-axis CNC milling controller, serving as the "brain" of the entire system. It boasts powerful computing capabilities, extensive control functions, and a convenient user experience. Specific performance highlights are as follows:

It seamlessly collaborates with the arm-mounted ATC-16 tool changer for automatic tool selection and switching. Comprehensive tool compensation (including length and radius compensation) allows real-time correction for tool wear or dimensional deviation after tool replacement, ensuring machining accuracy.

High-speed traverse and precise positioning: Supports rapid traverse speeds of up to 60 m/min and feed rates of 24 m/min. Rapid traverse reduces workpiece positioning time, and feed rates can be flexibly adjusted based on the material and process. Position control using pulse + direction/AB phase and 0-10V dual analog voltage outputs delivers high positioning accuracy and fast response, meeting the stringent position control requirements of precision machining.
