Coordinate hole grinding

Using the coordinate grinder to grind the coordinate hole is a common way of machining, the coordinate grinder is also named from this.

In addition, the polar coordinate hole L can be grinding.

When grinding coordinate holes, using the movement of coordinate work table, the coordinate holes of various sizes and sizes can be machined with the azimuth accuracy up to 2 ~ 5 bucket M.

Therefore, the coordinate grinder is particularly suitable for the dressing of coordinate holes deformed due to quenching after processing with the coordinate boring machine.

When grinding polar hole, coordinate boring and grinding telephone, there are two ways:

One is the indexing method, using the inversion work table for indexing;

The other is the coordinate method, using rectangular coordinates for calculation.

When the polar radius of the part is small and the dividing hole is large, the dividing method is of high precision, economy and convenience.

When the radius of polar coordinates is larger, the higher machining precision can be obtained by using the coordinate method due to the influence of the rotation precision.

In addition, on the coordinate grinding machine, the space plane, space polar coordinate hole and various kinds of inclined hole on the part can also be grinded by using the tilting work table and through the coordinate gage.
