Metal Machining Services

We offer many different machining processes using a wide range of lathes, drill presses, milling machines and other cutting tools for producing the right geometric shapes and sizes to your part specifications

Milling – The CNC machine uses a high-speed multi-point cutting tool that removes metal from a raw block or sheet. The machine controls the tool head, speed of the tool, cut deepness, speed, feed rate, and material coordination. Milling is commonly used on hard metals for cutting unique shapes and/or complex dimensions, such as geared, grooved, or slotted workpieces.

Turning – A CNC lathe machine spins material on a horizontal or vertical axis while a fixed single-point cutting tool moves around it, cutting the metal into the desired shape. This process is mostly used for cylindrical or rotational parts, but can also be used for threading, drilling, taper turning and reaming. Each operation requires individual set-up and appropriate tool changes.

Routing – span A rotating router bit cuts along the X- and Y-axes of softer sheet metals. With the workpiece secured on a table, the cutting tool moves along the material’s plane. This process works best for large-scale cutting applications like mass engraving/product development and thermoforming.

Boring – Cutting a minimal amount of material from inside the workpiece, and slowly feeding the boring tool along the workpiece’s axis to enlarge existing holes or create lateral holes with high accuracy and precision. Boring is a popular choice for achieving specific diameters in large components, such as engine blocks, industrial and consumer appliances, and aerospace applications.

Honing – A rotating abrasive stone removes excessive ruptured material to reach the base metal. Using controlled pressure, the abrasive stone rotates and reciprocates until resulting in a smooth and polished surface finish. Honing improves dimensional accuracy and bore tolerance in many applications, like consumer products, automotive, and construction/agriculture.
