Abstract

PURPOSE:To improve grindability and cooling capacity ever so better, by feeding a coolant solution fed out of the hole of a wheel flange to a blow hole of a grinding wheel under pressure. CONSTITUTION:A coolant solution 3 passes through a hole 4a of a spindle 4 and fed to the inside of a grinding wheel 6 under pressure via a hole 5a of a flange 5. And, the coolant solution 3 is discharged to an outer circumference of the grinding wheel 6 by dint of turning centrifugal force in the wheel 6 and washes clean the inside a blow hole, removing chips and the like therefrom. As a result, sharpness in the grinding wheel 6 comes to being favorable all the time, thus a heating crack or the like in time of grinding is preventable.

に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cooling a grinding wheel configured to supply coolant from the inside of a grinding wheel made of GC, for example, to improve grindability and cooling capacity during grinding.

ントの巻込みが悪く、そのため、砥石に目詰りが発生し
加工性および冷却能力を著しく低下させている。Conventionally, for example, coolant has been supplied to grinding wheels from the outer circumferential surface of the wheel, but due to rotational centrifugal force, the coolant is poorly drawn in, resulting in clogging of the grinding wheel, which significantly reduces workability and cooling capacity. It is decreasing.

本発明はかかる点に鑑み、加工性および冷却能力を向上

ことを主たる目的とする。In view of this, the main object of the present invention is to propose an economically superior coolant for grinding wheels that improves workability and cooling capacity.

゛以下本発明の一実施例について図面を参照しながら詳

ている。FIG. 1 shows an example of a coolant supply device for carrying out the present invention. In this device, the coolant liquid 3 sucked up by the pump 2 from the storage tank 1 passes through the hole 4a of the spindle 4 in the machine tool, and then passes through the hole 5a of the flange 5.
The grinding wheel 6 is supplied under pressure through the grinding wheel 6.

, and is sprayed onto the outer periphery of the whetstone 6 due to the rotational centrifugal force of the whetstone 6. During this water spraying, the coolant liquid 3 cleans the inside of the pores 6a of the grindstone 6 and removes chips and the like. As a result, the sharpness of the grindstone 6 is always good. Furthermore, whetstone 6
Since the outer circumferential surface is always lubricated by the coolant liquid 3, it is possible to prevent quench cracking during grinding.

A pressure of about 80 kg/cm2 or less is sufficient, and care must be taken as the grindstone will be destroyed if the pressure is about 80 kg/cm2. In FIG. 2, 6b indicates abrasive grains, 7 indicates a heavily damaged workpiece, 8 indicates a grindstone cover, and 9 indicates a surface plate.

なる。As described above, according to the present invention, a hole formed penetrating the inside of a rotating shaft of a machine tool is connected to a hole formed in a flange that holds a grindstone, and coolant is supplied from the hole to the pores of the grindstone. Since the structure is such that the liquid is pumped, it is possible to provide a method for cooling a grinding wheel that has advantages in workability and cooling ability compared to conventional coolant methods.
