The best tool for mold processing - Zhenggong CNC high-speed CNC machining center

What is high-speedCNC machining centerGenerally refers to milling processes where the spindle speed is above 10000r/min. High speed machining often uses high milling speeds and fast multiple passes to improve efficiency, with small diameter tools, appropriate feed rates, and small radial and axial cutting depths. High speed machining can solve the machining problems of new materials in practical applications, adapt to three-dimensional surface machining with high surface quality, high precision, and complex shapes, reduce and avoid inefficient electrical discharge machining, and solve the machining problems of thin-walled parts. High speed CNC machining centers can also reduce the number of handling and clamping times, avoid machining errors caused by repeated positioning, and improve both machining quality and efficiency. High speed machining technology is widely used for processing cast iron and hard aluminum alloys, especially for processing large cover stamping dies, forging dies, die-casting dies, and injection molds.

At present, the surface of plastic molds is becoming increasingly complex, and the hardness of the mold steel used is getting higher and higher, some even exceeding HRC64 or above, while the delivery time requirements for molds are becoming shorter and shorter. These market characteristics have put pressure on mold manufacturers. The emergence of high-speed CNC machining centers has solved difficulties for mold manufacturing enterprises, especially in the processing of small and medium-sized precision plastic molds, fully reflecting its advantages.

In order to adapt to rough and fine machining, light and heavy cutting, and fast movement in enterprises, while ensuring high precision (positioning accuracy ± 0.005mm), high-performance machining machinery is a key factor in achieving high-speed cutting. High speed CNC machining centers must have both a high-speed spindle system and a high-speed feed system to achieve high-speed material cutting processes. The key technologies include the following:

1. High speed spindle

high-speedspindleIt is the core component that determines high-speed cutting. With the continuous improvement of spindle speed requirements, the traditional gear belt variable speed transmission system can no longer meet the requirements of high-speed machining due to its own vibration, noise, and other reasons. Instead, a fast functional component - the electric spindle, combines the spindle motor and the machine tool spindle into one, realizing the integrated operation of the spindle motor and the machine tool spindle.

2. High speed precision bearings

High speed and high-precision bearings are used for high-speed cuttingmachine toolThe core component is the most critical component that determines the lifespan and load capacity of high-speed spindles.

3. High speed servo system　

In order to achieve high-speed cutting processing, aCNC machine toolNot only should there be a high-speed spindle, but also a high-speed servo system. This is not only to improve production efficiency, but also a necessary condition for maintaining the normal operation of cutting tools in high-speed cutting. Otherwise, it will cause rapid wear and temperature rise of the cutting tools, and damage the surface quality of the workpiece during machining.　

With the high-speedCNC machining centerThe application of high-speed milling in mold manufacturing and processing is becoming increasingly widespread. By using high-speed milling to process molds, not only can high speed and large feed be achieved, but also rough and fine machining can be completed in one go. This greatly improves production efficiency and creates more benefits for mold processing enterprises.
