eXturn - a revolutionary industrial platform for assembly of high-pressure piping systems
The Future of Automated Nut Assembly
eXturn™ is the world's first intelligent open-end fastening system — a precision-engineered, dual-motor automation tool that detects, grips, tightens, angle-controls, and verifies every nut without operator fatigue or inconsistency.
Where traditional tools depend on operator skill — eXturn thinks, measures, and executes. It turns a manual, error-prone process into a precise industrial workflow.
What Makes eXturn Revolutionary
Two Motors, One Automated Motion Sequence
Motor #1 – Intelligent Gripper System
- Self-aligning gripper automatically detects and centers around nuts (10–20mm range)
- Linear guide mechanism extends/retracts for fast engagement
- Adaptive grip force — adjusts to nut dimensions and material hardness
- Compact Swiss-made BLDC motor provides micron-grade positioning control
Motor #2 – High-Torque Fastening Drive
- Ultra-high torque density Swiss BLDC motor
- Swiss planetary gear (1:6) for power efficiency
- Custom worm gear (1:37) delivering exceptional mechanical advantage
- Precise rotation under load — without vibration or impact
The "Extra Movement": Continuous Tightening in Confined Spaces
This is where eXturn stands alone.
- Grip & align
- Rotate with torque control
- Auto-release + reposition
- Continue tightening
The tool performs its own micro-repositioning, allowing continuous rotation even where full rotation is impossible — something no ratchet, impact gun, or electric wrench can do.
Precision Control: Torque + Rotation Angle
Unlike any wrench, eXturn allows digital tightening specifications:
- Torque Mode – tighten until the exact programmed torque is reached (verified by motor current + torque profile)
- Angle Mode – rotate by a precise angle (e.g., "+90° from seating point")
- Torque + Angle (sequence) – meets automotive and aerospace fastening standards
Smart Control Interface (Control Station)
- Industrial touchscreen UI
- Jog/fine positioning for both motors
- Nut size preset selection
- Real-time feedback (current, temperature, position)
- Save multiple fastening profiles
- Emergency stop + LED status indicators
Corded or cordless — compatible with standard drill batteries or DC power.

eXturn doesn't just fasten. It verifies, documents, and proves the fastener was installed correctly.
Segev Technologies created the control system, electronics and software for eXturn.
We implemented our proprietary BLDC controllers to implement the drive section of the project.
