What is mill-turn machining?

Mill-turn machining is a machining method that combines turning and milling together, also known as mill-turn machining. It is a highly efficient machining method that allows the machining of many different shapes of parts in a single process.

Mill-turn machining usually uses CNC machining equipment to achieve simultaneous turning and milling processes by controlling the movement of the tool and the workpiece on multiple axes. This machining method is widely used in industrial production and can machine a variety of complex shapes, such as spirals, helical gears, worm gears, etc.

Compared with a single turning process or milling process, the combined turning and milling process has the following advantages.

The possibility of machining many different shapes of parts on the same equipment, which reduces the occupation of equipment and tools and improves productivity.
High machining accuracy, good smoothness of the machined surface and improved product quality.
the number of equipment changes during machining can be reduced, saving production time and costs
Suitable for machining complex surfaces and contours, improving the freedom of design.

Workflow of mill-turn machining?

Its workflow usually includes the following steps.

Designing parts: Firstly, it is necessary to carry out 3D modeling and program programming of the parts according to the product design requirements.

Equipment setting: Select the equipment suitable for turning and milling composite machining, and set the relevant parameters and machining tools, including the working range of lathe and milling machine, the installation position and rotation speed of tool, the clamping method of workpiece, etc.

Turning processing: According to the part program, the workpiece is clamped on the lathe, and the turning tool rotates along the axial direction of the workpiece and moves the tool for turning processing.

Milling processing: the head of the lathe is rotated to the milling tool position, and then milling processing is carried out. In the milling process, the milling tool moves in a straight line or curve relative to the workpiece to cut the surface of the workpiece to form the required shape.

Machining inspection: After machining, the part needs to be inspected and measured to ensure that its dimensions and surface quality meet the requirements.

Follow-up treatment: Finally, the finished part needs to be subjected to follow-up treatment, such as cleaning, polishing, coating, etc., for subsequent use or assembly.

How to solve the common problems of milling and turning?

In the process of turning and milling composite machining, some common problems may be encountered, the following are some solutions.

Insufficient accuracy of the workpiece: it may be caused by the unstable fixation of the workpiece or the irregular shape of the workpiece itself. It can be solved by optimizing the clamping device, increasing the machining rigidity, adjusting the cutting parameters, etc.

Poor milling surface quality: may be due to excessive tool wear, too fast cutting speed or milling depth is too large and other reasons. Can be replaced with new tools, adjust the cutting parameters, reduce the milling depth and other ways to solve.

Milling burrs: may be due to damage to the cutting edge of the tool or cutting speed is not suitable for the cause. Can replace the tool or adjust the cutting parameters to make the cutting speed appropriate to solve the burr problem.

Turning vibration: may be due to uneven cutting edge wear or cutting speed is too fast. Can replace the new tool, adjust the cutting parameters, so that the cutting speed is moderate to prevent vibration.

Turning surface burrs: may be due to serious tool wear or turning depth is too large. You can replace the new tool, reduce the turning depth, to ensure the quality of the turning surface.
