Machine tool with ultrasonic device

Abstract

A machine tool with an ultrasonic device includes a machine tool unit, a fastening unit, and an ultrasonic unit. The machine tool unit includes a working device and a worktable. The working device has a working member to process a workpiece. The fastening unit is disposed on the worktable to mount and fasten the workpiece. The ultrasonic unit is located between the worktable and the fastening unit. When the working member and the ultrasonic unit are activated, the workpiece is processed by the working member, and the ultrasonic unit generates ultrasonic vibrations to the fastening unit and the workpiece placed on the fastening unit to clear filings from the workpiece during operation to enhance the work efficiency greatly.

1 . A machine tool with an ultrasonic device, comprising
 a machine tool unit comprising a working device and a worktable, the working device having a working member to process a workpiece;   a fastening unit disposed on the worktable to mount and fasten the workpiece; and   an ultrasonic unit located between the worktable and the fastening unit;   wherein when the working member and the ultrasonic unit are activated, the workpiece is processed by the working member, and the ultrasonic unit generates ultrasonic vibrations to the fastening unit and the workpiece placed on the fastening unit to clear filings off during operation.   
     
     
         2 . The machine tool with an ultrasonic device as claimed in  claim 1 , wherein the machine tool unit comprises the working device, the worktable, a shift device and a cutting unit, the shift device comprising an X-axis shift portion, a Y-axis shift portion and a Z-axis shift portion, the shift device being used to control movement of the working member along X-axis, Y-axis and Z-axis relative to the workpiece, the workpiece being processed at a predetermined position, the cutting unit having a plurality of cutting members in different sizes, the cutting members functioning as the working member. 
     
     
         3 . The machine tool with an ultrasonic device as claimed in  claim 1 , wherein the fastening unit comprises an air hole and a vacuum device, the vacuum device being used to vacuum the air hole so as to fasten the workpiece. 
     
     
         4 . The machine tool with an ultrasonic device as claimed in  claim 1 , wherein the ultrasonic unit comprises an ultrasonic generator for generating ultrasonic vibrations to the fastening unit and the workpiece on the fastening unit. 
     
     
         5 . The machine tool with an ultrasonic device as claimed in  claim 1 , wherein the ultrasonic vibrations from the ultrasonic unit have an amplitude not exceeding a precision range of the working member to the workpiece.
