Fixture & VMC Machining
VMC fixtures, inspection gauges, leak testing machines and special purpose equipment
Our VMC machining capability extends beyond pattern making to custom fixtures, inspection gauges, and precision components. We manufacture 4-way VMC fixtures, GO/NO-GO gauges, leakage testing machines, shell core shooter machines, gravity die casting machines and special purpose equipment for foundries.

About This Service
A VMC fixture holds a casting in the exact position required for machining, ensuring all holes, faces, and bores are produced in the correct location relative to each other. A poorly designed fixture is the single biggest cause of dimensional scatter in machined castings — even when the VMC and tooling are perfect.
At Super Innovation, we design and manufacture VMC fixtures using 3D CAD — simulating the clamping forces, locating surfaces, and datum scheme before machining a single chip. We also manufacture complete special purpose machines (SPMs) — from shell core shooters to gravity die casting machines and water/air leakage testing rigs. If your foundry or machine shop needs a custom solution, we build it.
What's Included
Our Process
Datum Scheme & Clamping Design
We review the machined casting drawing and select the 3-2-1 locating datum scheme. Clamping forces are calculated to hold the part without distortion during heavy cuts.
3D CAD Design & Simulation
Full 3D CAD model of the fixture — including locating pins, clamps, base plate, and tooling access clearances. Simulated with the casting model to verify all features are accessible.
Machining & Assembly
Fixture body machined on VMC to ±0.005mm. Locating pins, rest pads and clamps fitted and verified against master casting. Trial machining run performed.
Proving & Handover
Fixture proved with 5–10 sample castings. Dimensional report shows all machined features in tolerance. Fixture dispatched with layout drawing and setup instructions.
Frequently Asked Questions
A VMC fixture is a precision device that holds a casting in a specific position and orientation during CNC machining. Without a fixture, the casting would move or shift during cutting, causing dimensional errors. Our fixtures use precision locating pins on datum surfaces and clamps that hold the part rigidly without distorting it.
