Features

• The system is versatile, suitable for various applications such as roughing, finishing, pin turning, and face grooving.
• Coolant supply is directed through all components to the cutting edge for optimal cooling.
• The components are mounted securely on the extension slide, ensuring the highest safety during operation.
• Flanges with a CKN connection enable the highest torque transmission with lightweight tools.
• The system features high-strength, hard-coated aluminum and nickel-coated steel components, offering scratch-resistant and rust-protected surfaces.
• Accurate balancing is achieved without a balancing machine, using a two-piece counterweight with a slide and scale.

◆ Super light system provides highest precision and performance

• The Series 318 Large Diameter Boring System is designed for heavy roughing of bores up to a diameter of 619.76 mm (24.4″).
• Its lightweight and secure configuration make it ideally suited for higher-speed operations up to 6600 SFM.
• The system is designed for use on production machines such as boring mills and machining centers with spindle taper sizes of 40 and larger.
• The system features aluminum extension slides of different lengths, which support a variety of aluminum and steel components for roughing and finishing tool assemblies.
• The mounting components are pinned to fit onto specific locations on the slides and secured with steel bolts.
• The precise positioning of the components on the slide, along with incremental adjustment scales for insert holders, allows diameter and length setting without the need for a tool presetter.
