1. Field of the Invention
The present invention relates to an ultrasonic tooth making machine which offers the advantages of quick tooth making, high precision size, resistant to deformation and high efficiency of powder waste and scraps removing.
2. Description of the Prior Art
A conventional tooth making process generally comprises the following steps:
In general, the conventional tooth making process is time consuming and will suffer the problem of thermal expansion and contraction, and therefore, the resultant tooth is likely to be deformed.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide an ultrasonic tooth making machine which offers the advantages of quick tooth making, high precision size, resistant to deformation and high efficiency of powder waste and scraps removing.
To achieve the above objective, an ultrasonic tooth making machine in accordance with the present invention comprises: a tooth making machine, a work table, and a vibration device.
The tooth making machine has a machine tool to perform machining operation.
The work table is mounted on the tooth making machine to hold a rough blank tooth, and the work table and the machine tool are able to move with respect to each other.
The vibration device is located between the work table and the rough blank tooth to put the rough blank tooth in an ultrasonic vibration environment.
When the machine tool is controlled to move with respect to the work tale while the vibration device is powered on, the rough blank tooth, in the ultrasonic vibration environment, is capable of being machined into at least one artificial tooth at one time.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
The tooth making machine 10 includes a machine tool 11 to perform machining operation.
The work table 20 is mounted on the tooth making machine 10 to hold a rough blank tooth 91, and the work table 20 and the machine tool 11 are movable with respect to each other.
The vibration device 30 is located between the work table 20 and the rough blank tooth 91 to put the rough blank tooth 91 in an ultrasonic vibration environment.
When the machine tool 11 is controlled to move relative to the work tale 20 while the vibration device 30 is powered on, the rough blank tooth 91, in the ultrasonic vibration environment, can be machined at one time into at least one artificial tooth 92.
In real application, the tooth making machine 10 includes the machine tool 11, a movable device 12 and a tool magazine 13. The movable device 12 includes an X axis movable portion 121, a Y axis movable portion 122 and a Z axis movable portion 123. The movable device 12 controls the machine tool 11 to move along the X axis, Y axis and the Z axis, so that the machine tool 11 can move with respect to and machine the rough blank tooth 91 at predetermined positions. The machine tool 11 is received in the tool magazine 13.
In the first embodiment, the work table 20 takes the form of a rotary device to drive the vibration device 30 and the machine tool 11 to rotate in a vertical manner, so as to enable the machine tool 11 to machine the rough blank tooth 91 which vertically rotates in the ultrasonic vibration environment into the artificial tooth 92.
The rough blank tooth 91 includes a glass-ceramic head 911 mounted on a glass-ceramic base 912, as shown in
The artificial tooth 92 can be ceramic tooth for tooth implant.
Referring to
The rough blank tooth 91 includes a glass-ceramic head 911, as shown in
The plurality of artificial teeth 92 are ceramic artificial teeth.
When the machine tool 11 is performing vibration machining on the rough blank tooth 91, the (ultrasonic) vibration device 30 can be used in combination with cleansing liquid (which is of conventional art) to carry away the machining-caused powder or scraps with the cleansing liquid.
In general, the present invention offers the following advantages:
1) the rough blank tooth can be machined at one time into a ceramic artificial tooth (for this machining method, the work table is a rotary device, the rough blank tooth includes a glass-ceramic head mounted on a glass-ceramic base), or the rough blank tooth can be machined into a plurality of artificial teeth (for this machining method, the work table is a stationary device and the rough blank tooth is a unitary glass-ceramic structure), hence, tooth making by using the device of the present invention is real quick.
2) the rough blank tooth is directly machined into an artificial tooth by using the machine tool without the thermal expansion and contraction problem caused by molding process, the size of the tooth formed by the present invention is precisely controlled and the formed tooth is resistant to deformation.
3) the whole tooth making process is carried out in a ultrasonic environment, namely, there is no powder or scraps left in the tooth making process.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
