BOURN & KOCH INC. MOTCH 142-VNC VERTICAL MACHINING CENTER

Technical Description

The Bourn & Koch Inc. Motch 142-VNC Vertical Machining Center is a powerful CNC vertical lathe engineered for precision turning operations. It features a robust main spindle with a maximum turning diameter capacity of 35.000 inches, supported by a large 36.000-inch diameter spindle chuck and a maximum swing of 42.000 inches. The spindle is driven by a 75 horsepower motor delivering speeds up to 620 RPM, enabling the machining of large and heavy components with ease. The machine is equipped with a 6-position tool turret, capable of handling one simultaneous cutting tool, optimizing tool changes and machining efficiency. It operates on a 2-axis system with controlled travel distances of 28.000 inches on the X axis and 24.000 inches on the Z axis. Both axes offer a top feeding speed of 125 inches per minute and rapid traverse rates of 250 inches per minute, allowing for efficient material removal and reduced cycle times. The Motch 142-VNC is particularly suited for medium to large part machining where precision and rigidity are critical. Its configuration supports complex turning tasks with consistency and high throughput, making it ideal for production environments requiring durable and flexible vertical turning solutions. As an OEM-supported model by Bourn & Koch, parts, service, and rebuild options ensure long-term operational reliability and maintenance support.
