3-axis machining center BF 15-21D

horizontalfor aeronauticsCNC

Overview
Part of the BF series, the BF 15-21D is engineered for dynamic machining of die-cast and structural components. It uses a hybrid platform with linear drives on the X and Z axes and a ball screw on the Y axis. The machine integrates proven multi-spindle architecture with two independent three-axis units and one spindle per working area, enabling replacement of two single-spindle machines and higher throughput within a smaller footprint.

Key features

• PRODUCTIVITY
  • Hybrid drive concept
  • Combination of linear drives (X/Z) and ball screw (Y)
  • Multi-spindle operation: two independent 3-axis units, one spindle per working area; option to use two spindles per area during automated part change
• QUALITY
  • Designed for fast machining of aluminum die-cast and structural parts
• USER FRIENDLINESS
  • Movable multi-touch control panel
  • Tool monitoring system
• FLEXIBILITY
  • Flexible automation solutions and customizable machine configuration
• ERGONOMICS
  • Accessible workspace and clear view of machining process
• ENERGY EFFICIENCY
  • Significant energy reduction versus single-spindle configurations (manufacturer data)
  • Minimal footprint per part
• SERVICE
  • Integrated data management for lifecycle support
