DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0041] 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.
[0042] Referring to FIGS. 1-5, an ultrasonic tooth making machine
in accordance with a first preferred embodiment of the present
invention comprises: a tooth making machine 10, a work table 20,
and a vibration device 30.
[0043] The tooth making machine 10 includes a machine tool 11 to
perform machining operation.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] The rough blank tooth 91 includes a glass-ceramic head 911
mounted on a glass-ceramic base 912, as shown in FIGS. 4-7.
[0050] The artificial tooth 92 can be ceramic tooth for tooth
implant.
[0051] Referring to FIGS. 8-10, an ultrasonic tooth making machine
in accordance with a second preferred embodiment of the present
invention is similar to the first embodiment except that: the work
table 20 is a fixed stationary device, the vibration device 30 is
located between the work table 20 and the rough blank tooth 91 to
the machine tool 11 to machine the rough blank tooth 91 which is in
the ultrasonic vibration environment into a plurality of artificial
teeth 92 at one time.
[0052] The rough blank tooth 91 includes a glass-ceramic head 911,
as shown in FIGS. 10-12.
[0053] The plurality of artificial teeth 92 are ceramic artificial
teeth.
[0054] 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.
[0055] In general, the present invention offers the following
advantages:
[0056] 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.
[0057] 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.
[0058] 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.
[0059] 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.
