Self‑centering design – automatically centers the workpiece for consistent positioning
Dual clamping modes – supports both external clamping (0–66 mm) and internal clamping (46–113 mm)
High jaw design – 65 mm overall height provides deeper workpiece engagement
Wide clamping range – 113 mm internal capacity handles larger workpieces
High repeatability – ±0.015 mm (0.0006″) for reliable production accuracy
Integral hardened jaws – one‑piece jaw construction for maximum rigidity and durability
Zero point ready – Ø52 pull stud hole for direct mounting on zero point pallet systems
High torque capacity – 70 Nm clamping torque for secure workholding
Compact and lightweight – 130×77 mm footprint and 2.8 kg weight save machine space
CNC milling and drilling – ideal for small to medium prismatic parts requiring centered clamping
Automated pallet systems – Ø52 pull stud enables quick change on zero point systems
Round and square workpiece clamping – external and internal modes handle diverse part shapes
High‑mix / low‑volume production – quick changeover between different part sizes
4th/5th axis machining – compact size fits tight rotary table envelopes
Tall workpiece clamping – high jaw design (65 mm) provides better grip on taller parts
Larger part clamping – 113 mm internal capacity accommodates oversized workpieces
Precision machining – ±0.015 mm repeatability for consistent part quality
Self‑centering advantage – eliminates manual centering, reduces setup time
Dual clamping flexibility – one vise handles both external and internal workpieces
High jaw design – deeper jaw engagement for taller or irregular workpieces
Integral jaw construction – one‑piece hardened jaws provide maximum rigidity
Zero point ready – Ø52 pull stud hole allows direct mounting on zero point pallets
Extended clamping range – 113 mm internal capacity for larger parts
Compact footprint – saves valuable machine table space
Precision ground surfaces – verified for flatness and parallelism
Hardened steel body – durable construction for high‑cycle production
