Graphite Machining Center

When selecting a Graphite CNC Machining Center, several technical aspects must be considered to maximize performance and achieve high precision levels. Here are the key characteristics to evaluate when selecting the machine best suited for your requirements:

■ Table Size and Work Capacity
Consider the maximum workpiece dimensions and weight capacity. The VMC700i offers a 510x700mm table, while the HT-600GS features a 630x500mm table. Both support 300kg loads, suitable for most graphite workpieces. Match these specifications to your typical electrode sizes and weights.

■ Control System Options
Haitong offers multiple CNC control systems including FANUC, GSK, and Siemens. The VMC-S640 supports various control options including Mitsubishi, while the VMC700i comes with FANUC control. Choose based on operator familiarity and existing shop floor systems.

■ Spindle Specifications
Spindle speed range and power significantly impact graphite machining capability. The HT-600GS features a 32,000 RPM BT30 spindle, while the VMC700i offers 24,000 RPM. The VMC-S640 provides 20,000 RPM capability. Consider your specific graphite machining requirements.

■ Tool Management
Tool capacity affects production efficiency. The VMC700i and HT-600GS offer 24-tool magazines with smaller capacity options available. The VMC-S640 provides 16/21 tool positions. Evaluate based on your electrode production requirements.

■ Precision Requirements
Different models offer varying accuracy levels. The HT-600GS achieves 0.003mm repeatability, while the VMC700i offers 0.005mm repeatability. Match these specifications to your electrode tolerance requirements.

■ Dust Management
Consider dust collection and containment systems. All models feature specialized designs for graphite machining with advanced dust collection systems to maintain a clean working environment.

■ Axis Travel
The VMC700i provides X/Y/Z travel of 700/400/300mm, while the HT-600GS offers 600/500/250mm. The VMC-S640 adds 4th and 5th axis options for complex electrode shapes. Match travel ranges to your part requirements.

■ Additional Features
Evaluate supplementary systems like thermal management, automatic tool changing, and high-rigidity spindle construction. All models include features optimized for graphite machining.

These factors should guide your selection process, but remember that each graphite machining requirement is unique. Haitong’s technical team can assist in determining the optimal configuration for your specific electrode production needs.
