The Bourn & Koch series of VBX-Modular CNC Machine Tools set the standard for the gear shaping. 1500VBS is used throughout numerous industries for accurately shaping medium and large sized workpieces. Our electronic helical guide allows for the ultimate versatility in a gear shaper.
Our 1500VBS is a CNC gear shaper designed as part of our VBX series of modular machine tools. With over 40 years machine tool building experience and 2500 years of combined American Machine Tool engineering in our archives, the VBS is a gear shaper designed, engineered and built with precision in mind. The VBS is based on the engineering of the legendary Fellows gear shaper. The components of the VBS are machined at Bourn & Koch, ensuring that our tolerances are not just met, but exceeded.
Bourn & Koch manufactures our VBS series of vertical grinders in three sizes from our 1000VBS up to our 2500VBS with a massive swing. 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 AGMA-class gears. Our conversational HMI guides the operator through the gear shaping process, reducing specialized training required to run the machine. Each VBS CNC machine tool is a crafted by precision machine tool builders with decades of experience.
1500VBS Gear Shaper Construction:
- 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 grinding 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.
- The work spindle is a self-contained unit mounted on precision radial/axial roller bearings with infinitely variable speeds of 0-40 RPM via an integral liquid cooled torque motor with 1800 Nm torque.
- The shaper head is directly driven by an integral torque motor with infinitely variable stroking speeds controlled via CNC.
