Turning is a fundamental machining process widely used in manufacturing to produce cylindrical and conical parts with high precision. It involves removing material from a rotating workpiece using a cutting tool, typically a single-point tool. This process is applied in producing components for various industries, including aerospace, automotive, medical, and energy. Our turning services cater to a wide range of materials and applications, providing high-precision solutions that meet the most stringent industry standards. This catalogue provides detailed insights into the turning processes, the machines used, and their specific applications.
Process Description: Straight turning is the most common turning operation, where the tool moves along the length of the workpiece to reduce its diameter. The process is ideal for producing cylindrical parts with a uniform diameter.
Machines Used:
- CNC Lathes (Computer Numerical Control Lathes): These machines provide high precision, automated control for consistent results in mass production and complex geometries.
- Manual Lathes: Often used for simpler tasks, such as one-off or low-volume production. ∙
- Vertical Turning Lathes (VTL): Used for larger workpieces requiring high torque and precision.
Applications:
Shafts, rods, and cylindrical components
Parts requiring high dimensional accuracy and smooth finishes
Key Features:
High tolerance and surface finish
Uniform diameter along the length of the workpiece
Process Description:
Taper turning involves gradually reducing the diameter of a workpiece from one end to the other to create a conical shape. This can be achieved by tilting the cutting tool or adjusting the lathe settings to control the taper angle.

Applications:
Valve bodies, bushings, and cylinders
Precision holes for bearing fits or mounting
Key Features:
High concentricity and dimensional accuracy
Smooth internal finishes
Process Description:
Facing is a process that cuts a flat surface across the end face of the workpiece, typically perpendicular to its axis. This is done to prepare the workpiece for further machining or to achieve a smooth, flat surface.
Machines Used:
- CNC Lathes: For automated, high-precision facing operations.
- Manual Lathes: For simpler, one-off tasks requiring a flat, smooth surface.
Applications:
Preparing surfaces for assembly or further machining
Creating flat surfaces for precision components
Key Features:
