What is a Milling-Turning Machining Center?

A milling-turning machining center is a machine tool that utilizes milling-turning machining technology to perform milling and turning operations simultaneously. It is essentially a combination of a CNC lathe and a machining center. Milling-turning machining centers typically have five axes: x, y, z, a, and c. Through multi-axis linkage, they can achieve milling-turning machining, and are adept at machining spatial curved surfaces, irregular shapes, hollowing, drilling, angled holes, and bevel cutting.

Milling-turning machining is one of the most advanced machining processes internationally, representing an advanced manufacturing technology and representing the fastest-growing and most widely used CNC equipment among composite machining tools.

Types of Mill-Turn Turning Machines

Popular mill-turn machining centers enhance standard turning machines by incorporating a Y-axis in addition to the powered turret. There are two main types of mill-turn machines: one features an orthogonal Y-axis, where the X and Y axes intersect at right angles, while the other uses a virtual Y-axis, in which the angle between the Y1 axis guide and the X axis is not a right angle. Typically, the angle between the X and Y1 axes is -35 degrees.

What are the advantages of mill-turn machines?

1. Shortened manufacturing process chain and improved production efficiency. Mill-turn turning can complete all or most machining operations in a single setup, significantly shortening the manufacturing process chain. This reduces auxiliary production time caused by changes in setup, as well as tooling manufacturing cycle and waiting time, significantly improving production efficiency.

2. Reduced clamping times and improved machining accuracy. Reduced clamping times to avoid error accumulation caused by changes in positioning references. Furthermore, most mill-turn turning machines have online monitoring capabilities, enabling in-situ monitoring and accuracy control of key manufacturing data, thereby improving product machining accuracy.

3. Reduced footprint and lower production costs. Although the unit price of mill-turn machining center equipment is relatively high, the reduction in the manufacturing process chain, the number of equipment required for the product, the number of tooling fixtures, the workshop floor space, and the equipment maintenance costs can effectively reduce the overall fixed asset investment, production operation, and management costs.
