The Bourn & Koch series of VBT-Modular Vertical Turret Lathe sets the standard for the vertical turning. Our VBT series of CNC machine tools is used throughout numerous industries for accurately producing medium and large sized workpieces. The VBT is designed for producing world-class precision for numerous industries.
Our VBT is CNC vertical turret lathe designed around a common base, crossrail and column. With over 40 years machine tool building experience and 2500 years of combined American Machine Tool engineering in our archives, the VBT series are CNC machine tools designed, engineered and built with precision in mind. Based on the engineering of the Bullard Dyn-Au-Turn and Motch VNC, the VBT is a vertical turning center engineered on time tested and proven designs. The components of each VBT base are machined at Bourn & Koch, ensuring that our tolerances are not just met, but exceeded.
Bourn & Koch manufactures our VBT series in three sizes from our 1000VBT up to our 2500VBT. Each machine is CNC controlled with servo-motion control on precision linear roller ways, hand-scraped bearing surfaces and accurate ball screws for easily achieving high tolerances. Our conversational HMI guides the operator through the machining process, reducing specialized training required to run the machine. Each VBT CNC machine tool is a crafted by precision machine tool builders with decades of experience.
- The base is constructed of heavy-duty, stress-relieved steel weldment with intelligently applied concrete polymer for additional dampening and to eliminate vibration.
- The column is a heavy duty, stress-relieved steel weldment with intelligently applied concrete polymer for additional dampening and to eliminate vibration. The column supports the vertical and cross slides and head under maximum work load.
- The cross slide is positioned by a precision ball-screw. The cross slide is equipped with both rapid traverse and feed in either direction.
- Precision way areas are provided in the column for mounting the cross slide on hardened and ground, preloaded, precision linear roller guide ways.
