Gundrilling is a special and unique machining service that creates a long, very straight, relatively small diameter hole. Typically, this specialized service is not a core competency of a machining organization.

MIC Group is pleased to offer in-house gundrilling to our customers to eliminate the extended project lead time associated with outsourcing.  This, in turn, saves our customers time and money.

  • Applicable to a broad range of materials.
  • Very accurate at high tolerances.
  • Easily repeatable
  • Smooth surface finishes
  • Eliminates need for deburring, reaming and work hardening.

Max Diameter & Max Depth1.5″ x 72″

Gundrilling summary

Ejector drilling provides the same benefits as gundrilling, only with greater diameters . This extension to our ability to make long straight holes enhances our service packages to our customers.

  • Ejector drills, also called a dual tube system, consist of a drill head, an outer tube, and an inner tube.
  • High pressure coolant is introduced through the space between the inner tube and outer tube.
  • Chips are discharged through the inside diameter of the inner tube and exhausted through an adapter mounted to the front of the machining spindle

Honing
A precise, smooth, and polished ID cutting process, honing uses polishing stones to gently create an ideal finish.

  • Extremely accurate
  • More efficient and precise than grinding.
  • High metal removal rate

Turning Summary

Electrical Discharge Machining (EDM) uses an electrical discharge or spark to remove material and is typically applied to complex dimensional shapes. This method is especially well-suited for cutting intricate contours or delicate cavities that would be difficult to produce with a grinder, an end mill, or other cutting tools.

MIC Group offers EDM as part of our specialty services. This capability allows us to provide a broader range of complex machining solutions.

  • Wire & Plunge
  • Material hardness has little to no negative impact.
  • Applicable to any material that is electrically conductive.
  • A highly precise and reliable method
  • No distortion on delicate sections or weak materials
  • Very good surface finishes
