In this work, both the eyes and the eyes are attached to a pedestal. Adjustments must then be made based on the number of holes to be drilled. Before starting the change to a different hole diameter, perform a first correction of the grinding wheel. The drilling platform is then moved in such a way that the base of the new hole is approximately in the correct starting position relative to the body surface. The first workpiece is then cycled 4-1 in an automatic cycle, followed by final grinding or correction by hand until the exact dimensions are reached. Next, apply the sharpening tool to the whetstone, and reshape the whetstone. A second workpiece is then machined in an automatic cycle. Based on the results of the new measurement, adjust the t&force of the eyeliner. These transients must be repeated until successive, coulometric grinding of the ready-to-drill workpiece is performed in an automatic cycle. Therefore, cutting to another drilling hole to be ground is time consuming and expensive.

Furthermore, Shiriichi 4! The grinding table is equipped with a grinding device and supports the pickling device 8, which is used for grinding feed and reshapingf)

At this time, do not move the eyeliner horizontally. Facilitation of remodeling and vI4 adjustment is achieved by this second pickling stand. This work is also applied to the CNC grinding machine,'t: In addition to the pickling table of the mortuary 2, the CNC-axis of the gruel 2 for the horizontal position d) is required. It is an expense.

The purpose of the invention is to optimize the positioning of the reshaping tool and to simultaneously adjust the diameter of the hole to be ground to a different diameter.
This is the shortest possible time.

The present invention includes a table supporting the grinding machine and additional movements for the purpose of adjustment to the drilling diameter, feed interlocking, and reduction of the grinding wheel diameter by reshaping and reshaping.
The force spread of the 1V fitting of the internal grinding machine with the I feed head set at υ is read again, and the diameter of the hole to be ground is different.

In the case of NC-controlled machines, the problem is to reduce the number of NC axes.

The present invention has solved this problem by providing a method in which the reshaping tool must maintain its position with respect to the grinding wheel during the adjustment movement of the conveying carriage to another diameter of the borehole to be ground and the diameter of the hole to be ground. The quotient of the second adjustment interlock of the reduced Pl @ customary tametsuku table is solved by following this.

Although the condition is above, the spring pressure brake is connected by a single curved clutch, and the brake is applied to the rudder.
＾The feeding table and the straight machine part, such as the guide part, can be combined.

In another configuration of the solution according to the invention, the B+ binding tool is located above the adjusting position of the mouth 1 movement with respect to the adjusting table, and the threaded shaft is inserted through the l Through a plating device, it can be reassigned to a transverse carriage or to a stationary rock t11 for connection to a section, such as a guide section. The advantage of the solution according to the invention is that the American version also has NC- and CN C-+
Adjustment movement, feeding movement, and reshaping compensation can be carried out using only one horizontal feed table on which a workpiece is placed on a TLLJ-controlled internal grinding machine. When moving to adjust to the desired drilling diameter, leave the dressing tool on the reference point of the grinding wheel and use the feed movement and R&L. It is located at the reference edge of hole 1 of the workpiece. As a result, it is possible to forcefully and accurately position the drilling tool directly through only one adjustment element. V) Expenses and time are therefore reduced to reduce NC-m in NC- or CNC-controlled machines.

Below, nine examples of the present invention will be explained in detail.

In a first embodiment of the 4-device shown in FIG. 1, a cross carriage 4 with a workpiece support 5 is arranged on the guide part 11 in the guide, which is not shown in the details.
