Since its inception, the UPX series machine tools have received high attention in the industry. This machine tool is a high-precision wire cutting machine designed and developed by Makino China, aiming to provide reliable technical support with high efficiency and low cost for the high-precision stamping industry. Let's walk into the UPX machine tool together and have a detailed understanding of its excellent performance.

Ultra precision roundness

Roundness concerns the linkage accuracy of machine tools, and mechanical rigidity is crucial for roundness accuracy during the entire machining process. The excellent mechanical rigidity of UPX ensures good stability and static output.

The first thing people associate with roundness may be the large rotating motor rotor mold of new energy vehicles. Rotary positioning, riveting and stamping, and roundness accuracy have become key! High roundness accuracy and good dynamic balance of riveted parts are necessary to maintain good power output and save energy consumption. So what kind of roundness accuracy can UPX machine tools achieve? Let's take a look at an example of machining: UPX400 machining φ 240mm circular hole, capable of achieving 1.52 μ Roundness of m, and can achieve Ra0.2 μ The ultra-fine finish of m. Please refer to the following for specific processing information:

Workpiece material: SKD-11

Using wire diameter: Brass φ 0.20mm

Number of machining tools: 5

Shape accuracy: 1.52 μ M/ φ 240mm

Measuring equipment: Talor Hobson

Positional degree

The positioning accuracy or the positional accuracy of the template pin hole is the first precision element of the stamping die. The UPX machine tool ensures the positional accuracy of processing from hardware to software in all aspects! Machine configuration 0.01 μ The grating ruler of m is used for full stroke precision grid position correction during processing; At the same time, the machine tool is also equipped with a unique constant temperature circulation system, which can maintain good positioning accuracy even after long-term processing. Specific processing capabilities can refer to the following examples:

(Stamping template position error<2) μ M/300mm)

Corner accuracy

Combined with ultra-high frequency pulse power supply, the PVG function of UPX machine tool has been further expanded and improved. By relying on intelligent servo and speed control of the machine tool, the machine tool automatically controls the processing status of the inner and outer corners of the arc. The real-time monitoring of the corner accuracy is carried out through a pulse power supply. The internal system of the machine tool allocates the precise radius of the arc corners and synchronously controls the sizes of different arc sizes, achieving a precision of 2 μ Synchronization accuracy within m.

The following example combines multiple precision punching molds and multi arc corner features for processing testing, and the measured corner accuracy reaches ± 1.5 μ M.

Impulse life

The punching life of stamping molds is an important indicator that reflects the level of technology and the results of wire cutting machining. The UPX series machine tools adopt an ultra-high frequency pulse power supply, equipped with a bed insulation design, and achieve a mirror effect on the processing surface, which can replace the work of some oil machines and effectively improve the punching life. The following machining examples show that the machining finish of UPX7 tool can reach Ra0.05 μ M:

Workpiece material: RD30

Using wire diameter: Brass φ 0.20mm

Workpiece size: 40x30x20mm

Number of machining tools: 7

Surface finish: Ra0.05 μ M

The UPX device has been officially put into the market, and we believe that in the near future, this device will definitely demonstrate more and better performance, providing more superior solutions for users! If you are interested in such an excellent UPX device, please feel free to contact us!
