【発明の詳細な説明】
本発明は、粗研加工に続くスパークアウト加工を行う精
密研削加工に適用される研削液の供給方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grinding fluid supply method applied to precision grinding in which spark-out processing is performed following rough grinding.
従来、研削加工においては、砥石によるワークの研削部
への研削液の有効供給量を増すべく、研削液の供給を高
圧多量化したり、ノズルの形状や配置位置に種々の工夫
を施している。Conventionally, in grinding processes, in order to increase the effective amount of grinding fluid supplied to the grinding part of the workpiece by the grindstone, the supply of grinding fluid is increased at high pressure, and various improvements are made to the shape and position of the nozzle.
特に最近では高速重荷重での研削を行う傾向にあつて、
研削液供給の高圧多量化が一層必要となつているが、こ
れによれば研削部に研削液の供給による動圧が作用し、
精密加工領域であるスパークアウト加工時においてはこ
の動圧による影響が大きく出て、寸法密度が不安定にな
る不都合を伴う。Especially recently, there is a tendency to perform grinding at high speed and heavy loads.
It is becoming more and more necessary to supply grinding fluid at high pressures and in large amounts, but with this, dynamic pressure due to the supply of grinding fluid acts on the grinding part.
During spark-out machining, which is a precision machining area, the influence of this dynamic pressure is significant, resulting in the inconvenience of unstable dimensional density.
本発明は、かかる不都合を解消した研削液の供給方法を
提供することをその目的とするもので、砥石によるワー

アウト加エヘの移行で減少させるようにしたことを特徴
とする。It is an object of the present invention to provide a method for supplying grinding fluid that eliminates such inconveniences, and it is an object of the present invention to shift the amount of grinding fluid supplied to the grinding part of the workpiece by the grindstone from rough grinding to spark-out processing. It is characterized in that it is made to decrease by.
次いで本発明実施の１例を別紙図面に付説明する。Next, one example of implementing the present invention will be explained with reference to attached drawings.

如く撓んだ状態から仝図点線示の状態に復元される際の
復元力を利用したスパークアウト加工を行う。In the drawing, 1 indicates the workpiece and 2 indicates the whetstone.Work 1 and whetstone 2
While rotating the wheels in the directions of the arrows, the grindstone 2 is sequentially cut into the workpiece 1 side as shown by line a in FIG. is stopped, and spark-out machining is performed using the restoring force when the workpiece 1 is pushed by the grindstone 2 and is restored from the bent state shown by the solid line in FIG. 3 to the state shown by the dotted line in the figure.
図面で３は研削液の供給ノズルを示し、該ノズル３は、
第２図に明示する如くワーク１の研削部に臨む上方の１
個と下方の左右１対とに設けられている。In the drawing, 3 indicates a grinding fluid supply nozzle, and the nozzle 3 is
As shown in Figure 2, the upper part facing the grinding part of the workpiece 1
They are provided on one pair at the left and right at the bottom.

エヘの移行に同期して、例えば上方の供給ノズル３から
の研削液の供給を停止し、研削液の供給量を例えば第４
図を線で示す如く粗研加工時の１／１０以下に減少させ
るようにした。According to the present invention, in synchronization with the transition from rough grinding to spark-out processing, the supply of the grinding fluid from, for example, the upper supply nozzle 3 is stopped, and the supply amount of the grinding fluid is increased, for example, from the fourth supply nozzle 3.
As shown by the line in the figure, the reduction was made to less than 1/10 of the rough grinding process.
第５図は切残し量の頻度分布を示し、研削液の供給量を
常時一定とした場合、仝図を線の如く切残しが多く寸法

の供給量の減少で、研削液の供給に伴う研削部への動圧

軽減されて、ワーク１が正確に所規位置に復元されるた
めであると考えられる。Figure 5 shows the frequency distribution of the amount of uncut material. When the supply amount of grinding fluid is always constant, there is a large amount of uncut material as shown in the line in the figure, making the dimensional accuracy unstable. It has been found that by reducing the amount of liquid supplied, the amount of uncut material is significantly reduced as shown by line a in the figure, and the dimensional accuracy is stabilized. This is due to the reduction in the supply amount of grinding fluid, which reduces the effect of dynamic pressure on the grinding part due to the supply of grinding fluid, reduces the influence of dynamic pressure on the restoration of the workpiece 1, and allows the workpiece 1 to be accurately positioned. This is thought to be due to the fact that it is restored to its original position.

効果を有する。As described above, according to the present invention, the supply amount of grinding fluid is reduced in the transition from rough grinding to spark-out processing, and the amount of supply of grinding fluid is reduced by the action of dynamic pressure on the grinding part due to the supply of grinding fluid. The effect of dynamic pressure during easy spark-out processing is reduced, allowing accurate processing and stabilizing dimensional accuracy.
