Summary

The SIP 7000/7 4A is an ultra-precision horizontal machining center engineered for extremely high long-term positioning accuracy and thermal stability. Capable of multi-axis machining (including continuous B-axis), it is designed for applications such as gearbox housings and spindle heads requiring sub-micron repeatability. Key technical features include a one-piece high-grade cast iron frame, hand-scraped geometry, and advanced spindle options including high-speed and deep hole boring variants.

Key Capabilities

• 4-axis horizontal machining with continuous B-axis rotation
• Bi-directional positioning accuracy within 3 microns (VDI/DGQ or ISO standard)
• Specialized spindle options for high-speed (up to 30,000 rpm), deep-hole boring, and grinding
• One-piece GGG80 cast iron frame supporting geometric stability without special foundations
• Friction-free V-profile roller guideways for precise, low-drift linear motion
• Manual hand scraping of key components for long-term precision
• Integrated CNC control options available from Siemens and Fanuc
• Part handling and integration with complex flexible manufacturing systems including Industry 4.0 compatibility
