External and Internal Grooving Service


External Grooving

Our External Grooving process delivers finely tuned cuts on the outer surface of various materials, ensuring that each groove meets the specific requirements of your project.

Key Features:

Processing Features: Smooth surface finishes, consistent groove depths, and uniform profiles.

Materials: Suitable for metals, alloys, plastics, and ceramics.

Tolerances: Maintaining tight tolerances up to ±0.005mm for absolute precision.


Internal Grooving

Specializing in intricate grooving within hollow parts or internal surfaces, our Internal Grooving service guarantees unmatched accuracy and finish.

Key Features:

  • Processing Features: Accurate internal profiles, seamless transitions, and optimal groove spacing.
  • Materials: Expertise in handling metals, high-performance plastics, and composite materials.
  • Tolerances: Precision-focused, achieving tolerances as stringent as ±0.005mm.


Axial, Radial, and Angular Grooving


Grooves parallel to the axis of the workpiece

Axial Grooving involves machining along the axis of a component, often essential for parts requiring linear grooves.

Key Features:

  • Processing Features: Uniform groove depths, linear alignment, and precision spacing.
  • Materials: Suitable for metals, alloys, plastics, and ceramics.
  • Tolerances: Precision is paramount, with tolerances maintained up to ±0.005mm.


Radial Grooving focuses on creating grooves that radiate outwardly from the center of a component, similar to the spokes on a wheel.

  • Processing Features: Perfectly symmetrical radial grooves, consistent depths, and uniform spacing.
  • Materials: Expertise in metals, thermoplastics, and composite materials.
  • Tolerances: Achieving tight tolerances up to ±0.005mm for maximum accuracy.

Angular Grooving is the art of machining grooves at specific angles, offering dynamic groove orientations.

Key Features:

  • Processing Features: Precise angle measurements, consistent depth, and smooth surface finishes.
  • Materials: Adaptable to metals, high-performance plastics, and ceramics.
  • Tolerances: Ensuring optimal precision with tolerances as strict as ±0.005mm.
