Design Purpose

This structure serves as an example for industrial product design, showcasing aesthetic CNC machining techniques, corporate promotional gifts, and surface finish analysis.

Deep Hole Drilling

Represents how the 6 deep chambers holding the pens are machined with flawless smoothness on a single axis without drill wander.

External Fluting

Demonstrates how the milled grooves (flutes) on the outer surface, originally meant to reduce weight and inertia on a real revolver, create an aesthetic grip feel in this design.

Indexing Notches

Highlights how the asymmetrical notches at the bottom, which lock a real cylinder in alignment with the barrel, add an industrial realism to the design.

Component Engineering Breakdown

Materials, manufacturing methods, surface conditions, tolerances, and functional roles of the major components.

Billet Cylinder Body

Industrial Design Product

Material & Manufacturing

6061-T6 Aluminum or Stainless Steel Billet

Surface Finish & Treatment

Bright Anodized (Gunmetal/Black) or Brushed

Tolerances & Technical Requirements

Visual perfection and chamfer symmetry

Functional Description

A heavy and stable desktop organizer shaped from a single solid metal billet on CNC lathe and milling machines.

Critical Points
  • Aesthetic deep grooves (Flutes)
  • Indexing Notches adding mechanical realism
  • Smooth reamed pen chambers
Engineering Note

In aesthetic parts like this, surface finish takes precedence over pure mechanical functionality. Reaming is applied to ensure no tool marks are left inside the chambers where the pens sit. To achieve flawless reflections on the outer surface, it goes through special polishing and anodizing steps after CNC milling.

Training Scope

This interactive module is intended for technical training, engineering visualization, component identification, and mechanical-system analysis. Numerical values, material selections, tolerances, and manufacturing details shown for individual components should be treated as representative technical information unless a specific manufacturer, drawing, or applicable standard is explicitly identified.
