How to Effectively Combine Turning and Milling Processes?

Modern multitasking CNC machines combine the functions of a lathe and a milling machine in a single machine. This allows both turning and milling to be performed in a single operation, which:

• reduces tool set-up time,
• eliminates the need to transfer the workpiece between different machines,
• increases accuracy by avoiding errors resulting from the need for multiple positioning.

Proper planning of the sequence of operations is crucial:

• Turning is often the first step to obtaining a cylindrical shape. At this stage, the part can be pre-shaped.
• Milling allows for the precise production of features such as slots, planes, holes, which require more complex machining.

Modern CNC machines are equipped with milling and turning heads, which enable both turning and milling without the need to change tools. These types of tools are numerically controlled, which allows for:

• fast and accurate milling operations on the turned object,
• better control over the geometry of the detail.

CAM (Computer-Aided Manufacturing) software supports the automation and optimization of processes. It allows for:

• planning all stages of machining in one program,
• process simulation, which helps to avoid errors and optimize the operation time,
• management of the order of milling and turning operations.

The use of multifunctional tools that can perform both turning and milling operations significantly shortens the cycle time and limits the number of tools in the process. Examples include:

• drills with the possibility of turning and milling,
• turning cutters enabling both operations.

The use of industrial robots to exchange parts between operations or to automatically load and unload parts from the machine significantly increases efficiency. The entire production line can then be automated.

Modern multi-tasking machines are equipped with measuring systems (e.g. probes) that enable automatic measurement of dimensions after turning and milling operations, which allows for:

• minimizing errors,
• ongoing correction of machining parameters.

Benefits of combining turning and milling:

• time savings by reducing the number of setups and operations,
• increased accuracy by avoiding positioning errors between different machines,
• lower energy and tool consumption by eliminating unnecessary operations,
• production flexibility, which allows the production of complex parts in a single machining cycle.

Combining turning and milling processes can significantly increase production efficiency, especially for parts with complex geometry and requiring high precision.

Turning-milling in one process directly supports comprehensive customer service, offering:

• faster order fulfillment,
• higher product quality,
• greater production flexibility,
• cost optimization,
• timeliness and reliability of deliveries.

This approach improves overall customer satisfaction, which translates into better business relationships and customer loyalty in the long term.
