Wintech Rapid provides CNC machining for rapid prototype making and on-demand manufacturing, with speed, accuracy and competitive cost. For prototype quantities of custom metal and plastic parts, CNC Machining is often the best process, short of tooling, to match proposed production-part properties. The process of CNC machining include CNC milling, CNC turning, EDM sparking, wire EDM sparking and laser engraving, polishing etc.
Looking for a reliable, quick-turn supplier of machined plastic and metal components? With hundreds of CNC machines, our unmatched in-house capacity ensures your parts are shipped on-time, every single time. At Wintech Rapid, our AS9100-certified CNC machining facilities are designed for both rapid prototyping and low-volume production of end-use components.
What Is CNC Machining?
CNC machining is a subtractive manufacturing process. Accordingly to the specification of your 3D design, we create precision CNC (Computer Numerically Controlled) machining paths and use software to control the equipment with a variety of precision cutting tools to remove the raw material to make a part or product.
CNC machining is not only to manufacture prototypes but also to be used for our plastic injection molding or pressure die casting services.
We can source whatever materials including magnesium, steel, aluminum, brass to meet your design requirements. The most common materials we utilize are:
Aluminum 6061, Aluminum 7075, SS303, SS304, SS316, Low carbon steel 1018, 1020, Brass, Copper, and more.
ABS, Polypropylene, PMMA ( like Plexiglas® acrylic), PC (polycarbonate, Lexan®), Nylon, POM (Delrin® acetal), and more.
CNC milling machine processing is based on the technical requirements of the shape, accuracy, size and surface roughness of the workpiece to determine the processing technology and processing parameters. Program the machining program into the controller and send the command to the servo. CNC milling machines can process parts with particularly complex contours or difficult to control dimensions, such as mold parts and housing parts. It has the advantages of strong adaptability, high processing precision, stable processing quality and high efficiency.
CNC turning is one of the most used machining methods in CNC machining. During CNC turning, the workpiece makes a rotary motion, and the tool moves in a straight line or a curve. While the tooltip moves relative to the workpiece, a certain workpiece material is removed to form a corresponding workpiece surface.
Benefits of CNC Machining
Highly accurate parts with tight tolerances
CNC machining can create parts with greater dimensional accuracy than most other common manufacturing technologies. During the final finishing machining steps, the material can be removed from the workpiece very accurately, achieving very tight tolerances.
The standard tolerance of any dimension in CNC machining is ± 0.125 mm. Features with tighter tolerance down to ± 0.050 mm can be manufactured and even tolerances of ± 0.025 mm are feasible. That is about a quarter the width of a human hair!
Excellent material properties
CNC machined parts have excellent physical properties, identical to the bulk material. This makes them ideal for applications where high-performance is essential.
Additionally, virtually every common material with enough hardness can be CNC machined. This gives engineers the flexibility to select a material with optimal properties for their application.
Quick turnaround times
The advances of modern CNC systems, CAM software, and digital supply chains have greatly accelerated the production times. Now CNC machined parts are typically ready for delivery within 5 days. This is comparable to the turnaround of industrial 3D printing processes,
