WIDMA’s Micro Gundrilling Machines (MG) series caters to the smaller diameter deep hole drilling applications in medical and automotive industrial applications.

These machines are developed on a modular design platform to ensure quick deliveries and greater flexibility. The MG series of machines are used in multiple industries, including the automotive, medical, and general engineering sectors. The machines come equipped with motorized (integral) spindles with variable frequency drive to facilitate high speeds for machining smaller diameters, high-pressure coolant systems with programmable pressure and flow control, and tool monitoring systems for better productivity and tool life. These proven machines are designed and manufactured to deliver flexibility, performance, and reliability and can be automated to maximize performance.

The MG series CNC machines have linear motion guides and ball screws for slide movement. The multi-stage filtration system in the coolant system improves the manufacturing quality and increases the product life. Some of the other features include full-fledged CNC system control, 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, and tool-setting gauges. WIDMA also provides optional features that can be added on requests such as tool monitoring system, mist collector system, automation for component loading and unloading, auto door with safety-light curtain and safety relays, and component counter-rotation for better hole accuracy.

These machines can also be customized as machining cells for injector body, nozzle holder body, element barrels machining. The benefits and advantages of the MG series of machines include:

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