Description
- CLGD1200 six-axis five-linkage blisk machining center is a special machine product developed for large-scale blisk processing, which should mainly meet the ultra-high requirements for the movement speed and acceleration range of each physical axis when the existing machine tool is performing the five-axis processing blisk action. It is a customized machine tool solution jointly created by Chenglong CNC and users to ensure that users maintain a key competitive advantage in machining.
- Blisk machining centers can be used to keep the tool and the 45 attachment head rotation centers as close as possible with longer tools, thus reducing the speed and acceleration requirements of RTCP actions on the linear axes. Blisk machining center has obvious advantages when machining large blisk disc, especially in the position that the rotation axis of the front trailing edge of the blade moves larger, the advantage is more obvious, and when using blisk machining center to process blisk, the movement speed and acceleration of each physical axis can be kept in a low range relative to the existing machine tool.
Character
Optimum stability and optimum force transfer
The overall layout of the machine tool is the overall layout of the movement of the column of the mature flat bed, and the spiral chip removal with a large inclination angle is used on both sides of the horizontal bed, and the chip removal is smooth. The linear guide of the moving column is equipped with 6 slides, which gives the machine the highest stability and the best force transmission from the cutting spindle to the machine bed. The slide table moves left and right along the bed (X-axis), the column moves back and forth along the slide table (Z-axis), the swing head moves up and down along the column (Y-axis), the 45 single swing head A axis is installed on the saddle, the turntable B axis is installed on the slide table, and the workpiece axis C axis is vertically installed on the workpiece axis. The machining point is near the central axis of the swing head and the central axis of the turntable, and the force direction is near the workpiece axis, the machine tool mechanism has good stress conditions, and the working area of the machining point is small, which reduces the requirements for X/V/Z three-axis speed and acceleration.
High-precision and high-speed milling machining
The 45° swing head A axis, the turntable B axis, the workpiece axis C axis and the motor spindle direct drive technology are directly driven by the torque motor, and the XY/Z three-linear axis adopts direct drive technology, and the workpiece axis does not participate in the linkage, and the remaining five axes realize the five-axis linkage. High-resolution and high-precision position feedback technology, full closed-loop, thermal deformation compensation and other technologies realize the high-precision and high-speed milling of the whole machine. It can process complex space surfaces to improve the performance and processing efficiency of the whole machine.
