We are focused on quality and customer service.

How CNC turning works.

CNC turning produces parts by "turning" rod material and feeding a cutting tool into the turning material. On a lathe the material to be cut rotates while a cutter is fed into the rotating workpiece. The cutter can be fed at a variety of angles and many tool shapes can be used.

Advantages of C and S Engineering's process.

CNC turning provides an economical way to make parts that are commonly symmetrical about an axis of revolution.

At C&S Engineering and Toolmaking lathes are multi axis, which means they are capable of milling and drilling in one operation.

Shapes.

Shapes that can be made include a variety of plain, taper, contour, fillet and radius profiles plus threaded surfaces. Although many turned parts use a single axis of revolution, there can be multiple axis to allow more flexibility (e.g. camshafts). This method of machining can be combined with CNC milling and other processes to make more diverse shapes. Examples of parts made include: Robot Parts, Shift knobs, Motorcycle Parts, Auto Parts, Toy Parts, Knobs, Pulleys, shafts, hubs, bushings, flywheels, etc.

Cost optimization.

Cost optimisations for turning include:

• Reducing complexity
• Minimising the amount of material removed
• Avoiding difficult shapes such as very long thin structures.

Materials 

The following rigid materials are commonly turned: Aluminum, Stainless Steel, Copper, Nylon, Steel, Acetal, Polycarbonate, Acrylic, Brass, PTFE, Titanium, ABS, PVC, Bronze, etc.

Design Considerations 

• As the turning process applies pressure to the material, weak shapes that may flex can be difficult to machine, such as long thin structures. 
• Turning generates a cut surface with fine helical feed marks resulting from the rotation of the part and movement of the cutter - consider specifying a desired surface roughness.
• Bored holes become difficult when the ratio of the depth to diameter is high.
