Design for Manufacturability (DFM) Focus
A 3D CAD model of the part is translated into machine instructions (G-Code and M-Code) by sophisticated CAM (Computer-Aided Manufacturing) software.

CNC Milling Machining Services in Hamilton, Ontario, Canada
Polymach offers precise CNC milling services in Hamilton, Ontario. We deliver high-accuracy parts with tight tolerances, fast turnaround, and reliable, cost-effective solutions for manufacturers across the GTA.
High-Precision CNC Milling Services
At Polymach, we use state-of-the-art 3-, 4-, and 5-axis CNC milling machines to produce components for a wide range of industries. Whether you require aerospace parts, medical device housings, tooling inserts, or industrial machinery components, our CNC milling process ensures precision, repeatability, and excellent surface finishes for every project.
How CNC Milling Works
CNC milling is a subtractive manufacturing process where a rotating multi-point cutting tool removes material from a stationary workpiece. Unlike simple drilling, our machines operate along multiple axes, efficiently producing complex geometries and smooth surfaces with minimal errors.
Design for Manufacturability (DFM)
We convert your 3D CAD model into precise G-Code and M-Code using advanced CAM software. This step ensures manufacturability, reduces production costs, and maximizes production efficiency.
Setup
The workpiece is securely clamped in a fixture or vise on the CNC machine table. Proper alignment guarantees precise cuts and consistent dimensional stability.
Cutting & Machining
The spindle rotates the cutting tool at high speed while moving along X, Y, Z, and rotational axes (A/B/C). As material is removed, your component takes its final shape with tight tolerances and excellent surface quality.
How CNC Milling Works
Unlike drilling, where the tool moves only along one axis, CNC milling involves continuous movement along multiple axes.
Setup
The workpiece (a block or solid piece of material) is rigidly secured in a vise or fixture on the machine's table.
CuttingMaterial Selection
The spindle rotates the cutting tool at high speeds while the machine controls the tool's movement across the X, Y, and Z axes (and rotational A/B/C axes for 4- and 5-axis machines), precisely carving the final shape by removing chips of material.
Our Milling Capabilities
Our investment in leading-edge technology ensures we can handle your most challenging geometry and tightest tolerance requirements.
3-Axis Milling
Ideal for parts with flatter surfaces, basic slots, and perpendicular features. It offers the fastest path to simple components
4-Axis Milling
Adds a rotation capability, allowing us to index (rotate) the part automatically to machine four sides without manual intervention. This increases efficiency and accuracy.
5-Axis Simultaneous Milling
Our highest capability, allowing the cutting tool and/or the workpiece to move along five axes simultaneously. This is crucial for manufacturing parts with complex contours, organic shapes, deep pockets, and for achieving superior surface finishes in a single setup, minimizing human error and setup time
