鏡面研削加工のような高精度研削加工においては一表面

美麗であることが要求される。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a horizontal shaft square table type surface grinder 1. [Background of the Invention] In high precision grinding such as mirror grinding, one surface roughening, In addition to quantitative accuracy such as shape accuracy, the surface quality of the ground surface when visually observed is required, that is, the surface is uniform and beautiful.

往復運動を行。Surface grinding machines that have various measures to improve precision in terms of mechanical elements are used for mirror surface grinding of flat surfaces, but the basic form of relative movement between the grinding wheel and the workpiece is similar to that used in general surface grinding. It is exactly the same as the disc. That is, as shown in a schematic diagram of the movement in FIG. 3, the table 2 performs a reciprocating movement within a range of a distance a.

を与えて、工作物3を研削加工する形式をとっている。The workpiece 3 is ground by applying a lateral feed of a distance between the grinding wheel 1 and the workpiece 3 placed on the table 2 at both ends of the stroke. .

b#こ相当するピッチの筋目がみられ、表面品位を悪く
するという問題点があった。Upward grinding and downward grinding are repeated alternately. In normal grinding, this is not a particular problem, but in high-precision grinding such as mirror grinding, due to the difference in the grinding mechanism between upward grinding and downward grinding, the state of light reflection from the grinding surface may be slightly different. There was a problem that a difference occurred, and streaks with a pitch corresponding to the lateral feed amount b# were observed, which deteriorated the surface quality.
本発明の目的は、上記した従来技術の問題点を除き、表
面品位のすぐれた研削面の得られる平面研削方法及び平
面研削盤を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a surface grinding method and a surface grinder that can obtain a ground surface with excellent surface quality by eliminating the problems of the prior art described above.
本発明の特徴はテーブル往復運動の片側のストローク端
でのみ横送りを与えることにより、常に上向き研削だけ
、あるいは、下向き研削だけで工作物を研削加工する点
にある。A feature of the present invention is that by applying lateral feed only at one stroke end of the table reciprocating motion, the workpiece is always ground only by upward grinding or only downward grinding.
以下、本発明の一実施例を示す第1図及びf82図によ
り説明する。Hereinafter, an embodiment of the present invention will be explained with reference to FIG. 1 and FIG. f82.
第1図は本発明の研削方法を示す模式図である。FIG. 1 is a schematic diagram showing the grinding method of the present invention.
同図において、テーブル2の1往復分の砥石1とこの千
−プル2の相対運動の軌跡を2本の線で示しているが、
これは説明の便宜上分けたものであって、実際には同一
軌跡上を往復運動する。In the same figure, the locus of the relative motion between the grindstone 1 and this thousand-pull 2 for one reciprocation of the table 2 is shown by two lines.
This is divided for convenience of explanation, and in reality, they reciprocate on the same trajectory.
本実施例の場合は、上記テーブル2が距離aの 、範囲

だけ横送りが与えられる。したがって図の矢印の方向か
ら見て、砥石1が時計方向回転の場合は上向き研削1反
時計方向の場合は下向き研削で研削された面のみが残り
、上向き研削と下向き研削の研削面が混在することがな
いので、常に均一な研削面となる。図では、テーブル2
のストローク右端でのみ横送りをかけたが、左端でのみ
横送りをかけてもよい。In the case of the present embodiment, the table 2 makes one reciprocation within a range of distance a, and only when it reaches the right end of the stroke, lateral feed is applied by the distance. Therefore, when viewed from the direction of the arrow in the figure, if the grinding wheel 1 rotates clockwise, only the surface ground by upward grinding will remain; if it rotates counterclockwise, only the surface ground by downward grinding will remain, and the ground surfaces of upward grinding and downward grinding will remain. This ensures that the ground surface is always uniform. In the figure, table 2
Although the horizontal feed was applied only at the right end of the stroke, it is also possible to apply the horizontal feed only at the left end.

運動を与える。FIG. 2 shows the configuration and control block diagram of a surface grinder according to the present invention. 4 is a bed, and 5 is a saddle which slides along a guide surface on the bed 4 in the front and back direction on the right side in FIG. 1, giving transverse feed to the workpiece 3. Reference numeral 2 denotes a table that slides along a guide surface on a saddle 5 in the left-right direction in the figure to apply a grinding motion to the workpiece 3.

ッチ(リミットスイッチあるいは近接スイッチがある。6 is fixed on the bed 4 by a column. A spindle head 7 moves up and down 11 along the guide surface of the column 6, giving cutting motion to the grindstone 1. The grindstone 1 is held by a grindstone shaft (not shown) which is rotatably held by a spindle head 7t. 8 is fixed to the table 2 with a dog, and 9a and 9b are detection switches (limit switches or proximity switches) for detecting the end of the table stroke.

The feeding finger ◆ is poisonous. The lateral feed motor 2 is rotated by this finger ◆Jζ, and a predetermined lateral feed is applied to the saddle 5.

るという効果がある。According to the above embodiment, since lateral feed is applied only at one stroke end of one side stroke of the left and right stroke of the table, the grinding process is always performed only by either upward grinding or downward grinding, which is due to the difference in the grinding mechanism. The effect is that a uniform and beautiful mirror surface can be obtained without the occurrence of streaks.
