Overview

CNC Machining.

CNC machining handles the precision work — drilled, tapped, milled, and bored features that need tighter tolerances than laser or punch can hold. At our Brampton shop, the Daewoo DMV-400 vertical mill bridges the gap between fabricated parts and machined-part precision, both under the same roof and on the same job ticket.

What it's used for

Tapped mounting holes, dowel-pin bores, faced reference surfaces, slots, pockets, and any feature held to ±0.001″. Used on fabricated frames that need machined mounting interfaces, jig and fixture work, prototype housings, short-run production parts, and the precision touch-up on parts that came off the laser or brake.

Why people use it

When a fabricated part needs a precision-machined feature, the machining work is often handled by a separate shop — which adds a week to the schedule and introduces a fresh tolerance stack. Because the DMV-400 lives on the same floor as our laser and brake, the part stays on one job ticket and the mill fixturing references the same datums the laser cut from.

What we hold to

±0.001″ on critical features, ±0.005″ on general dimensions. 31×16″ travel, 8,000 RPM spindle, 20-tool ATC. Mild steel, stainless, aluminum, brass, plastics. First-article dimensional inspection with calibrated tooling on every tight-tolerance job.

Workflow

From File to Feature.

A machining job touches five hands between your STEP file and the inspection bench. Here's exactly what happens — and where it happens — inside the shop.

Talk to a Fabricator

Send 3D Model + Drawing

STEP file with 2D drawing showing critical dimensions, tolerances, and surface-finish callouts. We program from the model and reference the drawing for verification.

Fixture Design + Programming

We program the toolpath, select tooling, and design or set up the work-holding fixture. Multi-feature parts often run from a single fixture.

First-Article Setup

Tool offsets dialed in on the first part. Critical dimensions measured (calipers, micrometers, gauge pins) before the production lot runs.

Production Run

Production parts run with in-process spot checks. Tool wear monitored; offsets adjusted as needed to hold tolerance through the lot.

Final Dimensional Inspection

Final inspection on critical features. CofC, dimensional report, and material certs ship with the parts on request.

Recent Work

Off the Mill.

Recent machining work that came off the DMV-400 — fixtures, tooling components, replacement parts, tight-tolerance prototypes. Single one-offs through pre-production pilots.

Where Buyers Get Stuck

What's Slowing Your Decision?

Three worries we hear from buyers vetting a precision machine shop. Here's what each one sounds like — and the honest reply, with the proof.

Buyer ObjectionsDocumented Replies

Three Worries

Worry 01

Worry

“I need one fixture, and the typical minimum I'm being quoted is 50 pieces.”

The Honest Reply

Single-piece work is welcome. The DMV-400 holds ±0.001″ on critical features whether the run is one fixture or a hundred — programming time is in the quote, no minimum order, no setup fee added after the fact. Tool steel, aluminum, and stainless are standard stock.

Why You Can Trust This

Single-piece work welcomed — no minimum order
±0.001" tolerance on critical features
Tool steel, aluminum, stainless — standard materials in stock

Worry 02

Worry

“Sending laser-cut parts out for milling adds two weeks to my schedule.”

The Honest Reply

We mill parts that come off our own laser and brake. Registration stays tight because the same fabricator owns the part across operations, and the mill fixturing references the same datums the laser cut from. Cut, bend, and mill all live in one building, on one job ticket.

Why You Can Trust This

Cut, bend, and mill on the same floor, on the same job ticket
Single PO, single delivery, single timeline to manage
Tight registration between machined features and cut geometry

Worry 03

Worry

“OEM discontinued the part — all I have is a worn-out sample.”

The Honest Reply

Send the sample, a photo, or a rough sketch. We reverse-engineer to drawing, match the material grade to the original, and machine a single replacement — no minimum, no tooling fee. Most one-off parts ship inside two weeks; the program stays on file for repeat orders.

Why You Can Trust This

Reverse-engineer from sample, drawing, or photo
Fast turnaround on prototype-volume work
Material match (stainless, tool steel, aluminum) to original

Milling (face, end, profile), drilling, tapping, counterboring, boring, reaming, and contouring on the DMV-400 vertical mill. We also do secondary machining on parts that have been laser cut or formed.

That's one of our core workflows. A part gets laser cut, press-brake formed, then milled for precision features — all without leaving the shop. One PO, one delivery, no second vendor.

±0.001" on critical features, verified at first article. Surface finish to your spec — 32 Ra typical, finer finishes available with appropriate tooling and feed rate. Material certs available on request.

Mild steel, stainless steel, aluminum 6061/7075, tool steel (A2, D2, O1), brass, and copper. Specialty alloys (Inconel, titanium) on request — we'll quote with material lead time included.

Yes — single-piece prototype work is most of what the DMV-400 runs. No minimum order, no setup-fee surprises. Production-equivalent process means your prototype matches what you'll get at volume.

Yes — same-day quotes for CNC machining work from anywhere in the Greater Toronto Area. Send your CAD file (STEP, IGES, SolidWorks, or DXF for 2D features) before noon and you'll have a quote back the same day. Free GTA pickup at our Brampton shop; production runs ship across Ontario.
