Secondary CNC Machining

Final Accuracy Operations

Secondary CNC machining that brings cast parts to final functional accuracy.

We handle the finishing operations needed after casting or forming when a component must reach tighter dimensions, cleaner faces, or assembly-ready features.

Secondary CNC Machining

Overview

Many parts need post-casting machining to reach their final geometry. This stage is used for bores, threads, holes, faces, slots, and other features that need tighter control than the primary forming process alone can deliver.

The goal is to keep the efficiency of casting while still achieving functional precision where it matters.

What We Support

  • CNC milling, drilling, and tapping.
  • Post-cast feature machining.
  • Fixture-based repeat processing.
  • Precision finishing for assembly areas.

Why It Helps

  • Improves final tolerance control.
  • Supports better mating and assembly fit.
  • Reduces variation across production batches.
  • Keeps primary casting cost-efficient.

Typical Workflow

01

Locate

We define datums and stable holding points for the part.

02

Sequence

Operations are arranged for accuracy and efficient tool access.

03

Machine

Required bores, faces, holes, and threads are processed.

04

Inspect

Critical features are checked before release to the next stage.

Common Uses

Die Cast Parts

Final machining of mounting faces, threads, and holes.

Tooling Parts

Machining support for inserts, plates, and precision items.

Industrial Assemblies

Part finishing before assembly or dispatch.

Batch Production

Repeat processing of near-net parts with fixture control.
