Product catalog summary
Overview: The document provides comprehensive technical details about the Grefors high-pressure clamping system, a mechanical machine vice designed for precision machining. It covers the system's specifications, benefits, and various configurations for different applications.
Specifications: The Grefors system features a mechanical clamping mechanism with adjustable force from 10% to 100% using a single crank rotation. It includes a modular system with versatile top jaws, a low base plate made of spheroidal cast iron, and encapsulated mechanisms for protection against chips and coolant.
Benefits: The system offers a robust design, high repeat accuracy, secure locking resistant to vibration, and high machining precision. It allows for quick clamping in less than one second without loss of clamping force due to mechanical force transmission.
System Overview: The modular design allows for various configurations, such as extended clamping ranges and different jaw types for specific applications. It is user-friendly, with manual adjustments possible without tools, ensuring consistent repeatability.
Applications: Suitable for clamping both blanks and machined workpieces, the system can be configured with soft top jaws for round workpieces or intermediate jaws for face milling multiple workpieces simultaneously.
Technical Information: The clamping force is mechanically generated and continuously adjustable using an adjustment ring. The system is easy to mount and dismount, with alignment facilitated by precision slot nuts on the machine table.
Product Variants: Various Grefors models are listed, including types 100, 125, and 160, each with specific dimensions, clamping forces, and order numbers. Accessories and replacement parts, such as different types of jaws and workpiece supports, are detailed.
