However, in such a conventional position detecting method, when a hard and brittle workpiece is processed with a diamond drill, cracks (largely broken pieces) or chips are generated, There was a problem that proper processing could not be performed.

For example, using the conventional processing method described above,
A processing experiment was performed on a quartz glass having a thickness of 1.0 mm as a material to be processed. In this processing experiment, hole drilling was performed using a diamond mounted wheel φ1.0 mm manufactured by Tokyo Diamond Tool Mfg. Co., Ltd. as a diamond drill.

As a result of the machining experiment, no matter how many times the machining experiment is performed, when the diamond mounted wheel penetrates the workpiece, as shown in FIGS.

The material 21 to be processed is a hard and brittle inorganic material such as quartz glass.

The resin 22 is a thermoplastic resin which becomes liquid when heated to a predetermined set temperature and becomes solid at room temperature. For example, pine, rosin, shellac, Dalman,
Natural resins such as balsam and synthetic resins can be used.

The resin 22 is a resin 22 which becomes liquid when heated at a temperature below the temperature at which the mechanical and physical characteristics of the material to be processed 21 are not impaired. Cerax asphalt
Tar or the like can be used, and as the synthetic resin system, it is possible to use a thermoplastic resin system having a property of being softened and deformed by heating, solidified by cooling, and repeating softening deformation by heating and solidification by cooling. it can.

Further, the resin 22 is thin and is solid in the state where it is hardened by cooling, and the work piece 21 and the support base 20 are bonded and fixed to form a pseudo integrated body. It is required that the work material 21 can be separated / removed without being deformed by being brought into a ready state and heated after working.

The support base 20 is a work material 21 to be processed.
It is formed of the same material as or a similar material.

Then, the work 3 is created by the following procedure. That is, first, the work material 21 is placed on the support base 20.
Is placed in an oven, the preset temperature of the oven is set to a temperature sufficient for liquefying the resin 22, and heating is started. Next, the set temperature of the oven, that is, the support base 2

When the temperature is reached, the support base 20 is taken out of the heating furnace, and the surface of the workpiece 21 to be bonded is rubbed with rosin, which is a solid resin 22. When the rosin that is the resin 22 is applied to the surface of the heated support base 20, the rosin is melted by the residual heat of the support base 20 and applied to the adhesive surface. After the resin 22 is thinly and uniformly applied to the surface of the support base 20 to which the work material 21 is adhered, the work material 21 is taken out of the heating furnace and is superimposed and pressed onto the application surface of the resin 22 which is a rosin at room temperature. When naturally cooled down, the work material 21 is joined and integrated with the resin 22 on the support base 20 to form the work 3.

As a countermeasure, for example, the support base 20 and the work material 21 may be superposed on a hot plate, then taken out and forcedly cooled by air or the like.

When the work 3 is created in this way,
By directly installing the work 3 at the processing position on the processing stage 2 of the processing machine device 1 shown in FIG. 1, pressing the upper surface of the end of the work 3 with the fixing clamp 4, and tightening the tightening screw 5, The workpiece 3 is fixed on the processing stage 2 by the fixing clamp 4.

The damage of the work material 21 and the damage of the diamond drill 8 due to clogging of chips in the gap between the hole and the diamond drill 8 are prevented.

The processing machine 1 includes the support base 20.
As the material 21 to be processed, the same or similar material is used. For example, when the material 21 to be processed is quartz glass, the support base 2
Quartz glass is used as 0. Therefore, the joined work material 21 and the work 3 of the support base 20 are pseudo-integrated in processing, and are hardened using the diamond drill 8 by a conventional processing machine device (for example, a milling machine, an NC milling machine, a lathe, etc.). And brittle work material 21 (for example, ceramics, glass, quartz glass, carbon, etc.) is appropriately prevented from being cracked or chipped, which is generated when the workpiece is processed, and thus the processing is free from cracks or chips. Can be performed with high precision.

When the processing is completed in this way, the work 3 that has been processed is removed from the processing stage 2 and

In this processing experiment, the pressure of the air supplied from the spray nozzle 11 was set to 3.5 Kg / cm2,
As a cooling solvent and cutting oil, a dry solvent manufactured by Nisseki Mitsubishi was used to supply and spray the cutting oil in the form of mist from the spray nozzle 11 to the vicinity of the processing.

As a result of the machining experiment conducted in this way, as shown in FIG. 3, it is possible to form a highly precise machined hole 30 in the material to be machined 21 without cracking or chipping. .

By spraying and supplying air and cutting oil from the spray nozzle 11, deformation due to temperature rise and damage to the diamond drill 8 are appropriately prevented, and chips are removed during the drilling process. It was possible to prevent damage to the expensive diamond drill 8 due to accumulation in the hole being machined, and to perform good hole machining.
