The invention further relates to a cutting or grinding rod favorably employable for processing an article of rigid material.
BACKGROUND OF THE INVENTION
The cutting or grinding machine equipped with a ultrasonic transducer, that is, a ultrasonic cutting or grinding machine, is well known.
Fig. 1 illustrates a known ultrasonic cutting machine using a grind stone as a cutting means. The ultrasonic cutting machine 10 comprises:
(1) a rotatable cutting unit composed of: a cutting rod 11 which is composed of a holder rod 11a and a grind stone lib; a horn 12 attached to the top of the holder rod 11a; a booster 13 attached to the top of the horn 12; a ultrasonic transducer (i.e., ultrasonic vibrator) 14 attached to the top of the booster 13; and a slip ring 15 attached to the top of the ultrasonic transducer 14;

The ultrasonic cutting machine 10 of Fig. 1 is oper- ated for cutting a workpiece (not shown) in the following manner:
The AC spindle motor 16 is activated under control of the servo unit 16b to rotate the rotatable rod 16a. The cylindrical cutting unit rotates synchronously with the rotation of the rotatable rod 16a under the condition that the cylindrical cutting unit is enclosed and held with the bearing 18. Simultaneously, a ultrasonic generator 19 generates and transmits a ultrasonic wave to the ultrasonic transducer 14.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the cutting or grinding rods employable for manufacturing the cutting or grinding machine of the invention are described below. (1) The cutting or grinding rod has the ultrasonic transducer therearound in the form of a continuous or divided ring.
(2) The cutting or grinding rod has a flange on which the ultrasonic transducer in the form of a continu- ous or divided ring is arranged.
(3) The cutting or grinding rod is a rod having a grind stone at its front end.
(4) The cutting or grinding rod is a drill.
(5) The cutting or grinding rod is an end mill. (6) The cutting or grinding rod comprises a holder rod and a throw-away tip attached to the holder rod. (7) The cutting or grinding rod comprises a holder rod and a throw-away tip attached to the holder rod, and the ultrasonic transducer is placed on the throw-away tip. The present invention is further described by referring to the figures shown in the attached drawings.
Fig. 2 illustrates an example of the cutting or grinding machine according to the invention.
In Fig. 2, the cutting or grinding machine 20 of the invention comprises an exchangeable cutting or grinding rod 21, a chuck 22 gripping the cutting or grinding rod 21 by its middle portion or its rear end, a motor 23 having a rotatable rod 24, and a transmission rod 25 connecting the chuck 22 and the rotatable rod 24 of the mo- tor 23. The cutting or grinding rod 21 has a ultrasonic transducer 26 thereon in an area between a front end 27 of the rod 21 and a portion 28 in contact with the chuck 22. The transmission rod 25 is held with a bearing 29 so that the rod 25 can rotate stably around its axis. Around the transmission rod 25, there is provided a slip ring 31 to which a ultrasonic energy is transmitted from a ultrasonic generator 31. A rotor (not shown) provided around the transmission rod 25 receives the ultrasonic energy from the slip ring 30 and then transmits it to the ultrasonic transducer through an electric line (not shown) arranged along the transmission rod 25. There is provided a workpiece 32 below the cutting or grinding rod 21. The workpiece is placed on a table 33.
The cutting or grinding procedure can be carried out in the following manner using the cutting or grinding machine of Fig. 2 according to the invention.
When the motor 23 is activated and a rotation energy is applied to the rotatable rod 24, the transmission rod 25 connected to the rotatable rod 24 rotates synchronous- Iy within the bearing 29. The chuck 22 provided to the bottom end (i.e., front end) of the transmission rod 25 also rotates synchronously together with the cutting or grinding rod 21 which is firmly gripped and held with the chuck 22. Simultaneously, the ultrasonic generator 31 is activated to generate and transmit a ultrasonic energy to the slip ring 30. The ultrasonic energy received by the slip ring 30 is then transmitted to the ultrasonic transducer 26. The ultrasonic transducer 26 generates ultrasonic vibration along the length of the cutting or grinding rod 21. The ultrasonic vibration generated in the ultrasonic transducer 26 is transmitted directly and almost predominantly to the front end (i.e., bottom end) of the rod 21. Only a small amount of the generated ultrasonic vibration is transmitted to the position 28 in contact with the chuck 22. Accordingly, the generated ultrasonic vibration is very efficiently utilized to vibrate the cutting or grinding rod 21. Further, since only a small amount of the ultrasonic vibration is transmitted to the chuck 22, the holding power provided to the cutting or grinding rod 21 by the chuck 22 hardly de- creases. Furthermore, damage of the chuck due to the transmitted ultrasonic vibration hardly occurs.
Fig. 3 illustrates a cutting rod according to the invention.
The cutting rod 21 of Fig. 3 is an end mill, and the end mill 21 has a ultrasonic transducer 26 therearound in the middle portion.
Fig. 4 is a schematic view of another example of the cutting or grinding rod according to the invention, and Fig. 5 is a section of the cutting or grinding rod of Fig. 4 taken along the line A-A.
The cutting or grinding rod 41 of Fig. 4 is a grinding rod having a grind stone at the front end (i.e., at the bottom) of the rod. The grinding rod 41 has a flange 41a. In Fig. 4, a ultrasonic transducer 46 is provided around the rod 41. The ultrasonic transducer can be provided around the flange 41a. Otherwise, one ultrason- ic transducer is provided around the grinding rod 41 and another ultrasonic transducer is provided around the flange 41a.
Fig. 6 is a schematic view of an example of the cut- ting or grinding rod according to the invention, and Fig. 7 is a section of the cutting or grinding rod of Fig. 6 taken along the line A-A.
In Figs. 6 and 7, the cutting or grinding rod 60 is a grinding rod 61 having a grind stone at its bottom end. The grinding rod 61 is in the form of a three-armed tuning fork having a flange portion 61a. On the flange portion 61a, there is placed a ultrasonic transducer 66 in the form of ring. The grinding rod 61 is gripped with a chuck by its upper portion. The grinding rod 60 can be made of a rod portion 61b and a flange portion 61a, and one of these portion such as the flange portion 61a can has the ultrasonic transducer 66, as is shown in Fig. 8. Otherwise, the ultrasonic transducer 66 can be placed not only on the flange portion 61a but also on the rod portion 61b, as is shown in Fig. 9.
The ultrasonic transducer can be in the form of a ring as shown in Figs. 3 to 9. Otherwise, the ultrasonic transducer can be in the form of a divided ring, as is shown in Fig. 10. In Fig. 10, a ultrasonic transducer is divided into four pieces 106a, 106b, --, which are placed on a box type holding means 105 provided around a cutting or grinding rod 101.
Figs. 11 and 12 illustrate an example of the grind- ing rod 111 having a grind stone 111b at the bottom
(front end) and an extended portion 111c. Four ultrasonic transducers 116 are placed on the extended portion 111c.
Fig. 13 indicates a cutting rod 141 having a pair of cutting throw-away tips 141d at the bottom (front end) and a ultrasonic transducer 146 in the form of ring. The pair of throw-away tips are preferably arranged symmetrically about the rotational axis of the rod 141.
The electric power supply to the ultrasonic transducer on the cutting or grinding rod can be supplied by means of a rotary power transformer, as is shown in Fig. 14. Fig. 14 is essentially the same as Fig. 2, except that the electric power supply system is replaced with a rotary power transformer consisting of an electric power supplying unit 141 and an electric power receiving unit 142 and that the grinding rod is replaced with the grinding unit of Figs. 6 and 7.
