Our Universal Gundrilling Machines (UGK) series are suitable for machining multiple holes on prismatic and shaft components, Few areas of applications are cooling holes on glass mold, ejector pin, and cooling holes of small and medium-size molds, hydraulic manifolds, and smaller size heat exchangers plates.

These gundrilling machines are standardized with three linear CNC axes and are available in various configurations of axes strokes and load-carrying capacities. UGK series machines can also be configured with multiple spindles to match higher productivity requirements in the auto sector. Horizontal and Vertical table positioning in UGK Series machines helps to achieve precise hole location and tolerance on various components. These proven machines are designed and manufactured considering flexibility and performance.

The UGK series CNC machines have linear motion guides and ball screws for all axes. Spindles are equipped with variable frequency drives to facilitate spindle speed variation. A high-pressure coolant system with a three-stage filtration system improves the manufacturing quality and reduces the manufacturing cost, increasing the product life. Some of the other features include a full-fledged CNC system, chip conveyor, fully enclosed sheet metal guard, panel cooler, hydraulic powerpack (HPP), Refrigeration unit for coolant tank, and nylon disc / Bag filter / compact band filter for fine filtration.

Along with the machine, we also offer tools and accessories such as gundrills, 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.C. servo spindle motor for spindle drive, tool monitoring system, chip crusher along with chip centrifuge, mist collector system, auto door with safety-light curtain and safety relays, and touch probe for component sensing.

These machines are designed to meet the machining requirement using insert type gundrills. The benefits and advantages of the SG series of machines include:

  • Stable operation without vibrations
  • Consistent accuracies
  • High feed rates and productivity
  • Increased tool life
  • Less energy consumption
  • Reduced maintenance
  • Ease of programming
  • Automation friendly
