Our Manufacturing Capabilities

Comprehensive machining and fabrication services to provide a one-stop solution for your precision parts needs.

CNC Milling

The workpiece is loaded into a special chuck in the center of the machine. The cutter moves on vertical and horizontal planes around the workpiece to cut it into precise shapes. Ideal for complex geometries and tight tolerances.

CNC Turning

Used for bar or cylinder-shaped components. A computer-guided cutter removes material while the chuck rotates at high speed, producing accurate cylindrical parts with excellent surface finish.

Wire EDM Machining

Works by creating an electrical discharge between a wire electrode and the workpiece. As sparks jump across the gap, material is precisely removed—ideal for intricate shapes and hard metals.

CNC Grinding

Uses a rotating grinding wheel to achieve fine material removal on metallic workpieces. Best suited for hard-fine machining and achieving ultra-precise dimensions and surface finishes.

Laser Cutting

Delivers quick turnaround and eliminates tooling costs for sheet metal cutting. High-precision, clean edges, and excellent repeatability for both prototyping and production runs.

Sheet Metal Fabrication

Involves cutting sheet metal and bending it using a press to create desired components. A cost-effective option for parts with uniform wall thickness and high-volume production.
