Description

High frequency oscillation spindle device

The invention provides a high-frequency oscillation spindle device and a processing method thereof, which can reduce the load weight of the actuation mechanism by using the high-frequency oscillation mode of the drive spindle device, thereby improving the oscillation frequency of the spindle head, and greatly improving the machining efficiency.

According to the processing of hard and brittle materials (such as glass, ceramic materials, zirconium dioxide, etc.), generally use high-frequency oscillation (frequency of 500 ~ 1000Hz) processing method, which performs high-frequency oscillation processing In the middle, between the tool and the workpiece, a small gap is formed which is easy to suck in the cutting fluid and discharge the chip, so as to greatly reduce the cutting resistance of the tool and reduce the deformation caused by the thermal stress generated by the machining. In contrast, the machining accuracy and processing of the workpiece can be improved. Surface quality and the life of the tool.

Referring to Fig. 1, there is shown a processing machine for processing hard and brittle materials, which is provided with a table 11 for mounting a workpiece 20 on a machine table 10, and a spindle head 12 for mounting the tool 30. The worktable 11 is coupled to the X-axis displacement module 13 and the Y-axis displacement module 14 for driving the table 11 to perform the machining feed displacement of the X-axis and the Y-axis, and is driven by the actuation module. The table 11 is configured to perform high-frequency oscillating motion in the X-axis and the Y-axis. The other machine 10 is provided with a column 101. The Z-axis displacement module 15 is coupled to the spindle head 12 on one side of the column 101 to The driving spindle head 12 is used for the Z-axis machining feed displacement; when the workpiece 20 is performed, the workpiece 20 and the spindle head on the table 11 are driven by the X, Y, Z axial displacement modules 13, 14, 15 The tool 30 on the 12 is used for the machining feed displacement of the X, Y and Z axes. During the machining process, the actuating module drives the table 11 to perform the high frequency oscillation movement of the X axis and the Y axis, and the height is high. The processing method of the frequency oscillation is performed on the workpiece; however, the driving table 11 is processed by the high-frequency oscillation motion, because the actuation module drives the table 11 When performing high-frequency oscillation, it is necessary to load the weight of the table 11 and the workpiece 20, and the heavier the weight of the workpiece 20, the greater the inertial force generated by the motion relative to the X and Y axes, and the inertial force will be limited. The actuation module drives the oscillation frequency of the table 11 and the workpiece 20, thereby failing to improve the machining efficiency and the service life of the tool; and to solve the drawback that the oscillation frequency cannot be improved, the spindle module 12 can be coupled to the actuation module to The spindle head 12 is driven to perform high-frequency oscillating motion. However, the spindle head 12 is coupled to the Z-axis displacement module 15 so that the spindle head 12 can only drive the high-frequency oscillatory motion of the Z-axis and cannot be driven as X and Y. The axial high-frequency oscillating motion can only be applied to the Z-axis feed machining (such as drilling), and the feed efficiency of the X and Y axes cannot be effectively improved.
