CNC Floor Type Boring Mills

Boring Mills

Product description

GMW boring mills are designed for the heaviest machining operations on large workpieces. The interaction of high-quality mechanical (casting) and control components guarantees high efficiency and accuracy in drilling and milling, turning and grinding.

Depending on the customer’s requirements and the field of application, the plate boring mills can be extended by the following modules:

Support sleeve spindles
Hydrostatic or linear guides
Controls from Heidenhain, Siemens or Fanuc
Tool changer
Cross slide
Rotary tables
Clamping plates

This increases the work contents per fixture. Through our network of technology partners, it is also possible to respond to the wishes of our customers with custom-made products.
