Portal Type Milling Machines

The purpose of developing Portal Type milling machines is the operating unit of the 5-axis Portal Type Milling machine, specifically designed and manufactured according to the customer's inputs and needs. This unit consists of seven basic devices; the ball screw feed system, hydraulic slide support system, hydraulic balancing system, positioning system, two brushless motors, two-range epicyclic reduction gearbox, and the Z-axis.

After the analyses, it is important to give a more accurate definition of two devices that will produce critical results: the reducer and the C-axis. The first device is a two-range epicyclic reduction gearbox consisting of three parts that transfer rotational motion to the spindle axis.

Regarding the C-axis, it is important to observe that such a device is not equipped with a spindle and only transmits the rotational motion of the main servo motor to the connection point with other accessories. This technical solution is related to the high flexibility required by the customer and the working purpose of the machine tool. The C-axis working mode depends on a specific device based on some overlapping rings created by springs; the pressure of the hydraulic piston straightens the ring and connects the C-axis to the rotating spindle.

Portal Type Milling Machines have been developed to achieve high accuracy and high performance during production at high speeds. As a result of the combination of metal processing operations, the design of rigid structures, the durability of components, and ultra-high quality craftsmanship factors, it has taken an important path in becoming an unstoppable resource for production. For this reason, Portal Type Mills, which have become popular in recent years, will undoubtedly find more place for themselves in the industry in the coming years.

To talk about the standard features of Portal Type Mills; the central lubrication system they possess plays an important role in creating the necessary security during production and ensuring that the part to be produced is not damaged. They have a spiral chip conveyor. Their ability to automatically cut power after the part is produced or in case of any security vulnerability will also ensure that you have a safe working environment. They have a work lamp to provide visibility advantage, and also a handwheel that you can use when you want to perform operations manually. They can prepare for an automatic chip conveyor. They have a cooling water system. The control unit heat control system is also one of the advantages it possesses, and it is one of the important features that distinguish Portal Type Mills from other milling types. Additionally, as expected, they have a spindle cooling unit. Thanks to the rapid movement of the axes, they have excellent dynamics and also have high power and high torque for high-performance machining. In some models, head and tool changing systems are automatic. It is possible to obtain precise and efficient machining results. Again, as one of its most important features; it can be said to have advanced stability that allows for high chip removal for prismatic components in a single setup for the mechanical engineering, energy, and capital goods industries. One or two operator platforms with relevant control panels ensure the operator's best position in every operation.

Although it varies according to the model, if we examine the general working way of Portal Type Mills, the advantageous situations we will observe as a result of this examination will be as follows; Specially designed inclined and cross beams support structural rigidity and the strong structure. The rigid body, linear roller slides, and high spindle speed ensure that the cut surface comes out perfectly precise. Thanks to the head with optional 1°, 2.5°, or 5° indexing feature, precise automatic processing can be performed on 5 surfaces of the part. The coolant and slide oil are completely separated. The design integrated into the monoblock base and the special coolant reservoir strictly prevent the decomposition and odor of the cutting fluid.

Some Portal Type Mills are specifically for high-precision aluminum plates. With the high surface quality obtained by these machines, it is now much easier to produce upper-segment aluminum plates. At the same time, because the production speed in Portal Type Mills is higher than other milling types and thanks to its high degree of automation, we can say that the production volume is at a very high level. In addition, the high degree of machine automation contributes to the significant increase in efficiency. The plates are automatically firmly attached to the machine with a vacuum clamp table, automatically opened when the upper side is ground, and automatically held down again.
