Customized CNC Machining Processes
CNC milling
CNC milling of parts commissioned by Redexpart is carried out on multi-axis machines controlled by modern computer software. Our rapid milling process is an advanced method for producing prismatic shapes and complex geometries.
Our CNC milling process is compatible with many types of raw materials. We use brass, stainless steel, hard plastics, titanium, aluminum and others.
With 3-axis CNC milling costs starting at $10 per hour and tolerances down to 0.002″ in a 5-axis CNC milling center, our CNC milling services for prototyping and part production are amazingly cost-effective .
CNC turning services
We use high quality high speed turning centers equipped with real time tooling and automatic bar feeders. The turning process uses materials such as aluminum, brass, hard plastics, mild steel, or stainless steel.
Redexpart's CNC turning services are designed to create complex external geometries with internal holes, resulting in exceptionally tight tolerances and brilliant surface finishes.
This process is suitable for rapid prototyping, new product introductions and low volume production.
Electrical Discharge Machining (EDM)
Electrical discharge machining is a process that uses an electric spark as a cutting tool to remove metal under controlled conditions. The spark literally corrodes the workpiece. We can then turn the eroded blank into a part of the desired size and shape.
This tool can be used to cut holes and pockets in hardened steel. EDM is often used to create square pockets. It is also used to provide surface texture to the internal cavities of molds.
A powerful electric spark is discharged by a sacrificial electrode located in a bath of electrolyte. An electrical spark can corrode extremely hard materials that cannot be eroded by any other method.
Wire EDM is a type of EDM process. In this case, an electrically charged wire fed continuously between two coils can cut hardened tool steel at high speed with impressive precision.

CNC machining is a subtractive manufacturing process that is carried out using high quality precision cutting tools and CNC machines.
Using these tools, we remove layers of raw materials from the workpiece. The blank can then be reworked into all sorts of shapes and sizes to create a unique and customized CNC part or product.
CNC machining is mainly used to produce parts and prototypes. However, it has other uses as well. Redexpart uses CNC to make the molds that we use in our plastic injection molding and injection molding processes. You can get a quote for CNC machining services online.
