CNC Turning and Turn-Mill Machining in Calgary

Precision turned and turn-mill components for energy, aerospace, and defence applications, completed in a single setup under an AS9100D and ISO 9001:2015 certified Quality Management System.

Turning and Turn-Mill

Complete Machining in a Single Setup

Fine Machine Works operates CNC lathes and advanced turn-mill systems alongside 3-, 4- and 5-axis (4+1) vertical machining centers in its Calgary facility.

Integrated turn-mill capability allows turned diameters, milled flats, cross-holes, and slots to be completed in a single setup. This improves dimensional integrity across features, reduces cumulative tolerance stack-up, and improves overall lead time.

Routine tolerances of ±0.0005 in (±0.013 mm) are achieved, depending on part geometry and material.

Why Turn-Mill

What Single-Setup Machining Delivers

Concentricity and Alignment

Turned and milled features are produced against the same datum, protecting the relationship between diameters and milled features.

Less Handling

Fewer transfers between machines reduce re-fixturing and the risk of handling damage on finished surfaces.

Shorter Lead Times

Consolidating operations reduces queue time between machines, supporting time-sensitive repair and production work.

Turning FAQ

Common Questions

What is turn-mill machining?
Turn-mill machines combine turning and milling in one machine, so round parts with milled features such as flats, slots, and cross-holes can be completed in a single setup. This protects the accuracy between features and shortens lead time.
What tolerances can you hold on turned parts?
Routine tolerances of ±0.0005 in (±0.013 mm) are achieved, depending on part geometry and material.
Do you machine oilfield mandrels and housings?
Yes. Mandrels, shafts, housings, adapters, and mechanical assemblies for downhole and surface equipment are core energy-sector work for Fine Machine Works.
What is the largest part you can turn?
Maximum turning diameter and length to confirm.
