Description
Characteristics of Summit® Heavy-Duty vertical boring mill and milling (VBM) machines
Summit® Heavy-Duty vertical boring mills and milling (VBM) machines offer smooth running, superior speed control, and maximum reliability in a cost-effective solution. Summit’s 48″ & 60″ (single column) and 80″ – 120″ (double column) vertical boring mills feature closed-grain castings that offer virtually the same thermal coefficient of expansion as steel. Additionally, maintaining excellent dampening characteristics provide enhanced dimensional part accuracy and constant surface quality. Summit’s Heavy Duty Vertical Boring Mills utilize the latest technologies to ensure high performance. These mills meet the ever-increasing demand for greater productivity in the machining industry. Summit’s machines consider at all times the need for versatility, easy maintenance, and economical production cost.
Boring mills, either vertical boring mills or horizontal boring mills, work similarly to turning lathes. Vertical boring mills work to widen or finish an existing drilled hole in metal. They operate similarly to a milling machine, in which the workpiece remains stationary and the milling cutter rotates at high speed. The basic function and uses of the vertical boring mill machine are highly specialized within industrial machinery.
The key difference between traditional boring and milling machines and a vertical boring mills turret lathe is the indexable turret. Both machine designs have a rotating table that supports the workpiece and uses a bridge-like structure with an X-axis. The ram crosses the X-axis guide rail and sends out the cutter, useful for handling large, heavy, or short workpieces. A vertical boring mills tools a bit with supporting boring bars. It also arbors to enlarge and accurately finish a large bore previously formed by casting.
Vertical boring mills accomplish 3 things:
- proper sizing
- straightness
- concentricity
Vertical boring mills can be adjusted to any diameter within the machine’s work envelope. Usually, this envelope is far larger than can be worked on by other machines’ tools. Vertical boring mills ensure concentricity between the inside and outside parts. Vertical boring mills and milling cutters primarily drill or machine cylinders.
Additionally, vertical boring mills are capable of spinning, boring, end nose, taper, and cutting internal and external threads.
