Our Universal Gundrilling Machines (UGC Series) series machines combine the benefit of deep hole drilling with milling, drilling and tapping operations in a single machine.
These machines can be configured from three axis up to seven axis, including rotary axis to perform complex and heavy-duty machining in a single setup. The drilling diameters range up to 40mm and depths up to 2000mm. These gun drilling machines are standardized with three linear CNC axes and can be configured up to seven axes, including heavy-duty rotary tables to perform complex machining in a single setup. These proven machines are designed and manufactured considering flexibility and performance.

The UGC series CNC machines have heavy-duty linear motion guides for slides and ball screws for axes movement. A high-pressure coolant system improves the manufacturing quality and reduces the manufacturing cost, increasing the product life. Some of the other features include chip conveyor, fully enclosed sheet metal guard, refrigeration unit for coolant tank, panel cooler, hydraulic powerpack (HPP), and nylon disc / Bag filter / compact band filter for fine filtration.

Along with the machine, we also offer tools and accessories gun drills, guide bushes, coolant retainers, damping bush, tool setting gauge, tool regrinding fixture, and tool resharpening machine. WIDMA also provides optional features that can be added on requests such as a tool monitoring system, chip centrifuge, auto door with safety light curtain and safety relays, and touch probe for component sensing.

WIDMA has expertise in offering solutions for machining multiple rows of holes on graphite blocks used in heat exchangers. We offer various configurations of machines having drilling diameters from 5mm up to 32mm and depths up to 1200mm. These machines are specially designed and manufactured to handle highly conductive graphite dust particles. Machines are offered with a single spindle as well as a twin spindle with a programmable center distance between spindles to meet the higher productivity requirements.

The machines can also be offered with CNC Rotary table and are equipped to handle cylindrical, square parts up to 1300mm and rectangular blocks up to 2500mm. Touch probes are provided for component sensing in case of mechanical clamping fixtures to ensure the positioning accuracy levels.
