Processing positioning differences
CNC Milling/Machining Center: Suitable for machining workpieces with larger milling volumes, such as roughing boxes and mold cavities, emphasizing heavy cutting capabilities.
CNC engraving machine: Focus on small milling volumes or fine machining of soft metals (such as copper, aluminum), such as relief, text engraving, and small mold finishing.
High-speed milling: For medium milling volumes, high speeds (15,000-30,000 RPM) and optimized cutting paths minimize subsequent grinding and near-net forming.
Differences in Mechanical Structure
CNC Milling/Machining Centers:
Non-moving components (bed, column) exhibit exceptional rigidity, while moving components (table, saddle) are similarly robust to withstand impact forces during heavy cutting operations.
Advantages: Capable of high-intensity cutting; Disadvantages: Limited flexibility, challenging to process intricate structures.
CNC Engraving Machines:
Non-moving components maintain good rigidity, while moving parts are lightweight yet sufficiently rigid to enhance flexibility.
Advantages: Suitable for micro-machining and high-speed precision machining of soft metals; Disadvantages: Unsuitable for heavy cutting operations.
High-Speed Milling:
Non-moving components exhibit exceptional rigidity, while moving parts employ lightweight designs (e.g., widened guide rail spacing, high-rigidity lightweight materials) to balance rigidity and high-speed motion requirements.
Advantages: High efficiency for medium-to-low cutting volumes with minimal reworking; Disadvantages: Improper operation can lead to rapid tool wear.
Differences Between CNC Systems and Spindles
CNC Milling/Machining Centers:
Typically require moderate-speed CNC systems with spindle speeds of 0-8,000 RPM, emphasizing low-speed high-torque output.
CNC Engraving Machines:
Require high-speed CNC system support with spindle speeds of 3,000-30,000 RPM, suitable for high-speed cutting with small-diameter tools.
High-Speed Milling:
Requires a CNC system with high-speed response capability. Spindle speeds range from 15,000 to 30,000 RPM. Equipped with oil-water cooling systems to maintain constant temperature. Spindle power must exceed 7.5-8 kW.
