CNC Turning

CNC turning is a machining process where a rotating chuck holds the workpiece in place and rotates at high speeds while a tool operates in a linear motion to remove material from the workpiece. The process is ideal for creating cylindrical parts. CNC turning centers often have 3, 4, or 5 axes to perform various tasks and follow pre-programmed instructions to control tooling and movement. This results in high precision machining with adherence to tight tolerances, allowing us to meet the exact specifications of our customers.

CNC Milling

CNC milling is a machining process that removes material from the workpiece using a rotating multipoint cutting tool to create the desired part. CNC milling performs well in manufacturing custom products from start to finish with the high precision of the computer-controlled process.

CNC milling is suitable for machining workpieces made from wood, glass, metal, or plastic. It is also an ideal solution for secondary or finishing processes for already machined workpieces, adding more definition or additional features to the part.

Surface Grinding

Surface grinding is a machining method that processes and grinds surfaces with high accuracy and efficiency. It relies on a rotating wheel with a coarse surface coating made up of various materials. The spinning wheel removes pieces of metallic or nonmetallic substances from the surface of the workpiece to create a smooth or flat surface.

By removing the oxide layer and other impurities from the workpiece, surface grinding creates a more refined look. Surface grinding methods include vertical swivel, horizontal spindle single disk, vertical spindle rotary, vertical spindle, and horizontal spindle grinding.+

EDM (Wire, Ram & Hole Drilling)

Electrical discharge machining relies on electrical energy to erode material from a workpiece. It works exclusively with electrically conductive materials, using an arc of high-frequency sparks emitted from between the electrode and the workpiece. The sparks erode microscopic particles from the workpiece, which are then flushed from the substrate using a dielectric fluid. Three distinct types of EDM include wire EDM, ram EDM, and EDM hole drilling.
