Vertical Bore VB160SF
The Winona Van Norman VB Series Vertical Boring Machines are engineered to deliver exceptional accuracy, rigidity, and productivity for automotive, diesel, industrial, and high-performance engine rebuilding. Featuring an advanced stationary boring head design with a movable worktable, the VB Series provides superior machining precision compared to conventional boring bar systems while minimizing setup time and maximizing throughput for professional machine shops.
Built with industrial-grade construction, the stationary boring head eliminates unnecessary movement, increasing rigidity and ensuring accurate, repeatable cylinder boring. Universal holding fixtures and a highly adjustable worktable allow operators to quickly position engine blocks, while side-to-side and fore-and-aft table movement makes it easy to precisely center each cylinder—even when the block is not mounted perfectly square. An integrated dial indicator further simplifies setup by confirming accurate cylinder alignment before machining begins.
For maximum versatility, the VB Series offers a wide range of adjustable spindle speeds and feed rates, allowing operators to optimize cutting conditions for different materials, bore sizes, and surface finish requirements. This flexibility extends tool life while making the machines especially effective for large overbores, where aggressive roughing cuts can minimize the need for secondary finishing passes. A micrometric manual feed provides precise depth control for counterboring cylinder sleeves, while adjustable automatic boring stops improve consistency and free operators to perform other tasks during the machining cycle. Depending on the model, automatic or rapid boring head retraction further enhances efficiency and productivity.
Designed for precision, durability, and ease of operation, the Winona Van Norman VB Series Vertical Boring Machines provide the performance and reliability professional engine builders depend on for consistently accurate, high-quality machining results.
