CNC milling
Three-, four- and five-axis machining centres for brackets, housings, manifolds, fixture plates and pocketed parts. Most five-sided parts are finished in one set-up.

02What we machine±0.025 mm
Milling, turning and the checks in between
Most parts we make need both: a turned body with milled flats, or a milled plate with a bored and reamed seat. Both happen under one roof, so one programmer owns your part from the first cut to the final report.
CNC turning
Lathes with live tooling, a Y axis and a bar feeder for shafts, pins, bushings, fittings and flanges, with cross holes and flats cut in the same chucking.
Ø ±0.01 mm (±0.0004 in)CNC turningInspection and finishing
A bridge-type CMM, first article reports and material certificates on request, plus anodizing, plating, black oxide and heat treatment through local partners.

Aluminum to PEEK, in the bar and plate sizes we know
We keep common stock on the rack: 6061-T6 aluminum, 1018 and 4140 steel, 304 and 316 stainless and acetal. Everything else is bought to order for your job, with mill test certificates when your customer asks for them. Not sure which grade to use? Tell us what the part does and we will suggest two options with the price difference.

From drawing to delivery, one operation at a time
Every job gets a traveller: the routing card that moves with your parts through the shop. This is what is on it.

Drawing review
Send a STEP, DXF or PDF. A programmer reads it the same day and flags anything that adds cost without adding function: a tolerance tighter than the fit needs, a deep pocket with sharp inside corners, a thread size nobody stocks a tap for.

Unit price at your quantities, material, finish, inspection level and lead time, in Canadian dollars. Repeat orders keep the same program and the same price until the material cost changes.

Program and first article
CAM programming, workholding, then one part measured in full against your drawing. On new work you can approve the first article before the batch runs.
OutputFirst article report - OP 40Run
Production
The batch runs with in-process checks at set intervals, recorded on the traveller so any part can be traced back to its machine, operator and measurements.

Finish, pack and deliver
Deburring, outside finishing, packing that protects machined faces, and delivery around Hamilton and Halton or by courier across Canada and to the US.

Parts for the lines, farms and plants around the Golden Horseshoe
We do not chase one industry. We make the parts that keep equipment running, for the people who maintain it and the engineers who design it.
Automotive
Fixture details, locating pins, gauges and end-of-arm tooling for plants that cannot wait for a part.
Agriculture
Shafts, bushings, hydraulic fittings and replacement parts for equipment older than its parts catalogue.
Food equipment
Stainless and food-grade plastic change parts, guides and star wheels with smooth, cleanable finishes.
Energy
Flanges, valve parts, pump shafts and test fixtures with heat numbers and material certificates kept on file.

Sample reviews
These are sample reviews written for this demo website. A real shop shows its own, with each customer's permission.
“The drawing had a ±0.005 on a face that only clears a cover. They called, asked what it mated with, and the price dropped once we opened it up.”
“A conveyor shaft snapped on a Thursday. We dropped off the broken pieces and had a new one in 316 on Monday, with the measurements written up.”
“First article report with every new part number, and the batch matched it. That is all I want from a supplier.”
