Next, the present invention will be described in detail with reference to the illustrated embodiment. In the figure, reference numeral 1 denotes a ceramic pipe as a workpiece for producing a solid electrolyte tube of a sodium-sulfur battery, and 2 denotes a support member for holding the ceramic pipe.
In the embodiment shown in FIG. 7, a rotary support rod for supporting the ceramic pipe from the inner diameter side is supported so as to be able to move arbitrarily in both horizontal and vertical directions. Also, 3
Is a rotary cutter that is parallel to the support member 2.

The rotary cutter 3 has a pre-cutting blade 5, a main cutting blade 6 on a single drive shaft 4 rotated by a motor 8.
The cutting surface finishing tools 7 are sequentially arranged. The preliminary cutting blades 5 and the main cutting blades 6 are located close to the preliminary cutting blades 5 and the main cutting blades 6 with a slight cutting margin. The outer diameter of the cutting surface finishing tool 7 is the largest for the preliminary cutting blade 5, then the main cutting blade 6, and then the cutting surface finishing tool 7.

In this embodiment, two blades, an outer peripheral surface cutting blade 7a and an end chamfering blade 7b, are mounted as cutting surface finishing tools 7, but either one of them may be used, or the other may be used. Needless to say, it is possible to arbitrarily combine tools and the like. In the embodiment,

With the above construction, when the support member 2 is moved while rotating the ceramic pipe 1 at a rotation speed of, for example, about 50 rpm to bring the rotary cutter 3 close to a predetermined position, the maximum outer diameter is firstly obtained. The pre-cutting blade 5 having a cutting edge is brought into contact with the outer peripheral surface of the ceramic pipe 1 to carry out pre-cutting while leaving an optimum cutting margin. Cutting is performed. In this case, the preliminary cutting and the main cutting are performed at the same time without moving the center of the ceramic pipe 1, so that the cutting can be performed with extremely high precision without causing a center shift. Since an appropriate cutting allowance is secured between the blade and the main cutting blade 6, the occurrence of chipping or the like is effectively prevented.

Thereafter, the preparatory cutting blade 5 is

The outer peripheral surface of the steel is ground, and then the support rod 2 is chamfered with an end chamfering blade.
By moving the cut end face portion in the axial direction to 7b and polishing it by the end chamfering blade 7b, the final finishing is completed. As described above, since the center of the ceramic pipe 1 is fixed at one place without being moved during the entire process from the start of cutting to the end of polishing, processing with extremely high precision is performed without causing center deviation. In addition, since these processings are continuously performed by one apparatus, the working efficiency is also remarkably improved.
