Summary

The Haas SB-28 Box Way Lathe is a CNC slant-bed turning center designed for high dynamic stiffness and precision turning of medium to large workpieces. Its core function is the controlled turning and milling of cylindrical parts, enabled by a box way construction for enhanced load-bearing and vibration damping, and a 12-station BMT65 turret supporting live tooling. Key differentiators include interpolated C-axis control, programmable hydraulic tailstock, and Turcite-B hand-scraped slideways for improved accuracy and durability.

Key Capabilities

• CNC turning and mill-turn operations with live tooling (BMT65, 4000 rpm)
• Box way construction with hardened, hand-scraped Turcite-B slideways for optimal stiffness and vibration damping
• 12-station turret supports any combination of OD/ID tools
• Programmable hydraulic tailstock (MT5)
• C-axis enables interpolated motion and precise positioning (±0.01°)
• 10" hydraulic chuck (A2-8), up to 2.9" bar capacity
• Advanced Haas control system with remote monitoring (Ethernet/WiFi, HaasConnect)
• Integrated chip and coolant management with variable flow and belt-type conveyor
