High Speed Machining Center - 5 Axis CNC Mill

The continuous improvement of work performance of high-speed machining centers is an important prerequisite for the efficient and high-precision processing of molds in the mold manufacturing industry. Driven by driving technology, numerous types of high-speed machining centers with innovative structures and excellent performance have emerged. The three-axis high-speed machining center that emerged in the mid to late 1990s has now developed into a five axis high-speed machining center. In terms of driving methods, it has evolved from servo motors and ball screw drives for linear motion (X/Y/Z axes) to linear motor drives. Rotary motion (A and C axes) uses direct drive torque motors, and some companies have developed machining centers into five axis machining centers using direct drive through linear motors and torque motors. Significantly improved the stroke speed, dynamic performance, and positioning accuracy of the machining center.

Advantage:

The price of a five axis high-speed machining center is much higher than that of a three-axis machining center. According to the price comparison between the DMC75V series five axis machining center and the three-axis machining center by Demagi, the price of a five axis machining center is about 50% higher than that of a three-axis machining center. Although the price of a five axis high-speed machining center is high, this high-end machine tool is particularly suitable for processing molds with complex geometric shapes.

When machining deep and steep cavities, a five axis machining center can create optimal process conditions for end milling cutters through additional rotation and swing of the workpiece or spindle head, and avoid collisions between the tool and the tool holder and the cavity wall, reducing the risk of tool shaking and tool damage during machining, thereby improving the surface quality, machining efficiency, and tool durability of the mold. When purchasing a machining center, whether to choose a three-axis machining center or a five axis machining center should be determined based on the complexity and accuracy requirements of the mold cavity geometry.

From the continuous innovation process of high-speed machining centers, it can be seen that fully utilizing the latest achievements in the field of technology, especially the latest achievements in driving and control technology, is the key to continuously improving the high-speed performance, dynamic characteristics, and machining accuracy of machining centers.

Operational requirements: The continuously improving working performance of high-speed machining centers is an important prerequisite for the efficient and high-precision processing of molds in the mold manufacturing industry. Driven by driving technology, numerous types of high-speed machining centers with innovative structures and excellent performance have emerged. Do not place obstacles around the high-speed machining center, ensure that the workspace is sufficiently large; Do not splash water or oil on the ground. Ensure that the work floor is clean and dry; Do not move or damage the warning signs installed on the machine tool. Ensure that the safety warning signs are clear and prominent

Do not touch the switch with wet hands, otherwise it may also cause electric shock; Before pressing the switch, make sure it is correctly connected to avoid danger caused by incorrect connections; Familiarize yourself with the location of the emergency stop button to ensure that it can be pressed without searching for it whenever needed.

Those who have not received safety operation training are not allowed to operate high-speed machining centers, and generally two people are not allowed to operate high-speed machining centers at the same time. If a task requires two or more people to complete it together, coordination signals should be specified at each step of the operation. Unless the specified signals have been given, do not proceed to the next step of the operation. Do not change system parameter values or other electrical settings. If the high-speed machining center needs to be changed, the original value should be recorded before the change, so that it can be restored to the original adjustment value if necessary.
