Why use CNC machining on a laser-cut part?

Laser cutting efficiently defines the overall shape, but it cannot produce partial-depth features such as counterbores, chamfers, or precision threads. CNC machining adds these blind or high-accuracy features with ± 0.001" precision, delivering the optimal balance of laser speed and machining accuracy.

How do you ensure quality on complex machined parts?

Graphie acts as the single point of accountability. Regardless of machining complexity — 3-axis or 5-axis — every component is verified against engineering drawings and tolerance requirements before delivery. This simplifies quality assurance for our customers and ensures consistent results across production runs

CNC MACHINING

CNC Machining and Precision Finishing

While laser cutting offers speed and efficiency for defining part geometry, certain mechanical features demand the physical precision of a cutting tool. Graphie provides CNC machining services dedicated to the processing and finishing of metal components. Whether refining a laser-cut plate or producing a complex machined part, we ensure every feature meets the tight tolerances required by the transportation and industrial sectors.

Based in La Pocatière, Quebec, Graphie supports manufacturers across Canada and the United States with precision-machined components integrated directly into our metal fabrication workflow. By combining machining with laser cutting, bending, clinching, and welding, we deliver parts that are not only cut to shape, but truly ready to assemble.

Generalist and Advanced Machining Capabilities

Graphie manages a full spectrum of CNC machining capabilities, ranging from standard geometry to complex multi-directional features. Our machining services include precision milling and access to advanced 5-axis machining, enabling the production of components with complex contours, angled features, and tight-access geometries.

Our machining department produces components with exceptional precision, ensuring that even high-complexity 5-axis parts meet the same quality standards as our sheet metal fabrication.

Integrated 3-Axis Machining Center: The Finishing Specialist

Our production floor includes a dedicated 3-axis CNC machining center, optimized specifically for secondary operations on plate metals such as aluminum, stainless steel, and carbon steel. This equipment is the natural extension of our fiber laser cutting capabilities.

Typical machining operations include:

Chamfering (Chanfrein): Precise beveled edges for weld preparation, safety, and part handling.

Counterboring & Countersinking (Chambrage): Flat-bottomed or conical recesses that allow fastener heads to sit flush with the surface.

Tapping and Reaming: Threaded holes and precision bores requiring tighter tolerances than thermal cutting can provide.

These operations are commonly integrated into recurring production runs, eliminating secondary handling and ensuring consistent quality from batch to batch.

Technical Specifications and Tolerances

Precision is defined by data. All machined metal components; up to 1 inch in material thickness; are produced according to strict dimensional standards.

Machining Tolerances

Positioning Tolerance: ± 0.001 inch

Dimensional Tolerance: ± 0.001 inch

Countersunk, Radius, and Chamfer Tolerances

For secondary features and finishing details:

Positioning Tolerance: ± 0.001 inch

Dimensional Tolerance: ± 0.005 inch

Angle Tolerance: ± 1 degree

Materials We Machine

We focus exclusively on industrial-grade metals commonly used in OEM and equipment manufacturing:

Aluminum: Aluminium 6061-T6, aluminium 5052 H32
Stainless Steel: Stainless 301, stainless 301L, stainless steel 304, stainless 304L, stainless 316 and stainless 316L
