Manufacturing Capabilities
Our Precision Machining Services encompass a comprehensive range of high-accuracy processes essential for modern tooling and component production. These include jig grinding, profile grinding, surface grinding, wire EDM, CNC machining, EDM, milling, and drilling—all executed with stringent quality controls to ensure superior part precision and consistency.
Equipped with a fully staffed toolroom and cutting-edge equipment, including Moore Jig Grinders, WASINO Profile Grinders, Seibu Water-based Wire EDM, Sodick Oil-based Wire EDM, and Taiwan-made AWEA, AGMA, and Vision Wild CNC machining centers, we streamline workflows to reduce lead times without compromising quality.
Jig Grinding is a specialty grinding process that allows us to grind precision holes, slots, pockets, and contours in tools and components with extremely high precision and accuracy.
True Roundness: ± 0.001mm
Processing Accuracy: ± 0.001mm
Wire EDM refers to a machine or machining process in which a thin wire is used as an electrode to cut through a metallic workpiece. The XY table of the machine moves around a stationary wire. Wire EDM can be used to cut a shaped punch followed by a matching die opening into a die plate, most often for a blanking die or progressive die.
Wire Diameter Range: φ 0.05 ~ 0.3mm
Processing Accuracy: ± 0.001mm
Surface Roughness: Ra0.05, Rz0.1
A high-precision grinding process is used to achieve intricate contours and complex geometries in stamping dies. It ensures tight tolerances and smooth surface finishes, which are critical for maintaining die accuracy and part consistency.
Grinding Precision: ± 0.001mm
Surface Roughness: Ra0.05
This versatile technique uses computer-controlled machinery to precisely remove material from a workpiece according to programmed instructions. It allows for high levels of accuracy, repeatability, and complexity.
