Cutting or grinding machine

Abstract

A ultrasonic cutting or grinding machine is composed of an exchangeable cutting or grinding rod, a chuck holding the cutting or grinding rod at a middle portion or rear end thereof, a motor having a rotatable rod, and a transmission rod connecting the chuck and the rotatable rod of the motor, in which the cutting or grinding rod has a ultrasonic transducer on its rod in an area between a front end of the rod and a portion in contact with the chuck.

1 . A cutting or grinding machine comprising an exchangeable cutting or grinding rod, a chuck gripping the cutting or grinding rod by a middle portion or rear end thereof, a motor having a rotatable rod, and a transmission rod connecting the chuck and the rotatable rod of the motor, wherein the cutting or grinding rod has a ultrasonic transducer thereon in an area between a front end of the rod and a portion in contact with the chuck.  
   
   
       2 . The cutting or grinding machine of  claim 1 , wherein the cutting or grinding rod has the ultrasonic transducer therearound in the form of a continuous or divided ring.  
   
   
       3 . The cutting or grinding machine of  claim 1 , wherein the cutting or grinding rod has a flange on which the ultrasonic transducer in the form of a continuous or divided ring is arranged.  
   
   
       4 . The cutting or grinding machine of  claim 1 , wherein the cutting or grinding rod is a rod having a grind stone at a front end thereof.  
   
   
       5 . The cutting or grinding machine of  claim 1 , wherein the cutting or grinding rod is a drill.  
   
   
       6 . The cutting or grinding machine of  claim 1 , wherein the cutting or grinding rod is an end mill.  
   
   
       7 . The cutting or grinding machine of  claim 1 , wherein the cutting or grinding rod comprises a holder rod and a throw-away tip attached to the holder rod.  
   
   
       8 . The cutting or grinding machine of  claim 7 , wherein the ultrasonic transducer is placed on the throwaway tip.  
   
   
       9 . A cutting or grinding rod having a ultrasonic transducer thereon.  
   
   
       10 . The cutting or grinding rod of  claim 9 , wherein the ultrasonic transducer in the form of a continuous or divided ring is placed around the rod.  
   
   
       11 . The cutting or grinding rod of  claim 9 , wherein the rod has a grind stone at a front end thereof.  
   
   
       12 . The cutting or grinding rod of  claim 9 , wherein the cutting or grinding rod is a drill.  
   
   
       13 . The cutting or grinding rod of  claim 9 , wherein the rod is an end mill.  
   
   
       14 . The cutting or grinding rod of  claim 9 , wherein the rod comprises a holder rod and a throw-away tip attached to the holder rod.  
   
   
       15 . The cutting or grinding rod of  claim 14 , wherein the ultrasonic transducer is placed on the throw-away tip.
