A mill turn machining center is a machining center that can conduct milling and turning process based on its designed mechanical structure without additional systems and assistances.

What are mill turn machining centers?

A mill turn machining center is a machining center that can conduct milling and turning process based on its designed mechanical structure without additional systems and assistances. That is to say, a mill turn machining center is able to do milling cutting as well as turning process, but is more similar to turning mechanism regarding the in born design.

Categorizations of machining centers

Categorizations of machining centers can be roughly divided into two main categories: vertical and horizontal, and there are still other categories in the machining center inventory. Vertical machining center is the arrangement of its structure that aligns vertically, and the work pieces are machined by cutting tools that goes upward and downward in a vertical direction.

Meanwhile, horizontal machining centers have the spindle arranged horizontally and the machining is conducted lying flat. With the vertical design, the weight of the work piece would help to make itself sternly located on the clamp for heavy vertical cutting route without much worry on route deviation. Furthermore, by the help of powered turret, the cycle time is thus shortened in a significant scale. The work piece machining of machine centers are normally not of round shape but other complicated profiles since the former one can be dealt with by turning machine with power turret in a much more efficient way.

The advantages of mill turn machining center

The classification of the CNC turn mill machine varies, and there are mainly two primary types in this category. That is, the vertical turn mill machine, and the horizontal turn mill machine. For the former, the work piece is fixed (as by clamping force) vertically and the cutting tool is thus installed the same direction so that the machining is conducted vertically. CNC mill turn machines could be either vertical or horizontal, and the arrangement is based on the machining demands.

High speed mill turn

In addition, high speed machining center is a highly developed machine tool that can deal with many precision machining tasks all at once. At first, machine center is developed from milling machines at the mid of the last century and since then, the development of this specific type of machine tools goes well in the industry, and after that, machine centers are widely applied in all kinds of industries, contributing a wide range of industrial efforts. In regard to milling process, it is the process of machining that utilizes spinning tools to remove work piece materials by advancing a tool into one or several work pieces. This machining method could be done on different directions. Besides turning, milling covers a wide variety of various operations and ranges a wide scale from single tiny parts to heavy and large milling operation tasks. Similar to turning, milling is one of the most usually adopted machining methods that render precision tolerances and standards.

Mill-turn spindle

Regarding the speed of the spindle, it is a key parameter that determines the performance of the machining center. For high speed models of mill turn machining centers, the RPM (revolutions per minute) standards differ and there is no such a common range. Meanwhile, manufacturers in the Europe, Japan, and Taiwan have their consensus way of RPM standards, while the regional differences still are significant. Accordingly, in the metalworking sector, a turn and mill machine is also known as a CNC turning center; this is a machine tool capable of both turning and milling functions and rotates a work piece on an axis of rotation to perform various, machining operations such as cutting and turning assistance during the process.

Powerful cutting assistance

Up to now, all of the discussions above are ideally processed with turret tools that are applied to the work piece and to create an object with symmetry with the axis which is driven by the primary spindle and assisted by live tools. As all the tools are prepared for the work pieces, so the clamping mechanism of the work piece is another critical point for the mill turn. In this way, the clamping mechanism is much more rigid and fixed due to the gravity effect compared to the horizontal methodology and manufacturers of vertical turning machines usually made their vertical turning machines into great manufacturing facilities for users in a variety of industrial sectors that pursue for high precision, such as automotive industry, aerospace sector, sport equipment application, and other fields with larger size work pieces.

Milling in the past

CNC turn mill machines are just like other machining center models as this type of machining center are coming from the very common and productive machine tools that is applied to heavy cutting tasks in the industrial sectors such as aerospace, automotive, and energy generation. Inside the model inventory, turret type CNC turn mill machine is a highly developed machine tool that can deal with multiple types of milling tasks at once. At first, machine center is evolved from milling machines at the 1960s and since then, the development of this specific type of machine tools progresses well in the industry, and after that machine centers are widely applied in all kinds of industries, contributing a wide range of practical utilizations.
