Types of Machining Services
We offer a full spectrum of custom machining solutions to meet diverse precision manufacturing needs. Our advanced equipment and skilled team enable us to deliver high-quality metal and plastic parts for various industries.

CNC Milling
Utilizing computer-controlled cutting tools, CNC milling creates complex shapes, contours, and features with exceptional accuracy. Ideal for both prototyping and mass production of components with tight tolerances.

CNC Turning
CNC turning is used to produce cylindrical or round parts by rotating the workpiece against a cutting tool. This process is perfect for shafts, bushings, and threaded components requiring precise diameters and finishes.

Precision Drilling
Advanced multi-axis CNC technology delivers burr-free, high-tolerance holes in hardened tool steels for mission-critical components, ensuring superior surface integrity and production efficiency.
3-Axis Milling
3-axis CNC milling involves cutting along three linear axes: left-to-right, back-and-forth, up-and-down. Easy to program and operate, 3-axis mills are effective for simple geometric designs and can be used for a wide variety of parts.
5-Axis Milling
5-axis CNC milling expands the design potential of the machining process by adding two axes of movement. With no need to reposition between operations, 5-axis milling allows for faster production of more complex parts.
CNC Turning
CNC turning involves the application of a cutting tool to a rotating blank workpiece in order to shape a desired part. During production, the workpiece spins on vertical or horizontal axes while the automated lathe moves around it. Precise, repeatable and scalable, CNC turning is ideal for creating parts with simple geometries in rounded or cylindrical shapes.
