を行なうため煩わしい欠点がある。 When performing cylindrical grinding of conventionally hard and brittle workpieces,
One diamond cup wheel grinding wheel
As shown in Fig. 6, the center axis a of the workpiece A and the grinding wheel are aligned so that the center C of the wall thickness t on the end face of the grinding wheel is located in the cutting line direction with respect to the cutting surface on the outer periphery of the workpiece A. The axis b of the wheel is the center C of the wall thickness t of the grinding wheel.
The workpiece A is rotated at high speed from a direction perpendicular to the workpiece A, and the workpiece A, which is clamped between the main spindle and the tailstock rod, is rotated at a low speed, The amount of movement of the workpiece A is determined by the wall thickness t of the grinding wheel per revolution.
The grinding wheel is moved at a feed pitch of 1 to 2 times that of the grinding wheel, and cutting is performed using the end face, inner surface, and outer circumferential surface of the grinding wheel. At this time, when the wall thickness t of the grinding wheel is thinner than the width of one pitch that the workpiece A moves in one rotation, cutting is performed on the outer circumferential surface and the end face, and when it is wider than the wall thickness t, the wide part is left as cutting residue. This debris is pressed and scraped off by the inner surface of the grinding wheel, and intermediate finishing is performed after rough cutting in the next pitch and the next pitch, and final polishing is performed in the next pitch. A grinding and cutting method in which rough cutting to finishing is carried out in a single continuous process is known by the present inventor as Japanese Patent Publication No. 16400/1983. However, even if cylindrical grinding, which can be performed from rough cutting to finishing machining with chipping in one step like the method described above, requires surface grinding after grinding or grooves must be made in the workpiece. A situation arises. In such cases, it cannot be done with the same grinder, so a different grinder is used. For this purpose, surface grinding involves the trouble of marking, and especially when a plurality of surfaces are ground, indexing and the like are required, which is a troublesome drawback.

等の不便と時間及び精度面からも不都合がある。 Furthermore, a milling machine using two shafts is known as shown in Japanese Utility Model Application Publication No. 52-67694. The two shafts of this milling machine include a first main shaft for attaching a milling cutter arranged vertically to the main body and a second main shaft for attaching a milling cutter arranged horizontally to the main body. The second milling cutter is used to cut horizontally and to cut grooves. That is, in order to perform cutting when it is desired to make a groove in a horizontally cut surface, the two axes are provided in the vertical direction and the horizontal direction, as described above. Therefore, when cylindrical grinding of such a product is performed, a separate grinding machine or the like must be used, which is inconvenient in terms of centering, time, and accuracy.

要者によつて望まれていた。 In addition, in the former cylindrical grinding described above, a cup-wheel grinding wheel is used, and the end face of the cup-wheel grinding wheel performs rough grinding to finishing for efficiency reasons, but since the cup-wheel grinding wheel is also used for surface grinding, cylindrical grinding is performed. When the need for surface grinding arises after grinding, customers have desired that surface grinding can be carried out using the same grinder without using a separate grinder, thereby streamlining the work.

ものである。 The present invention has the above-mentioned structure, and before starting grinding, in the case of cylindrical grinding, the grinding wheel surface of the cup wheel grinding wheel 27 attached to the tip of the grinding wheel shaft 21 supported by the bearing 23 of the elevator plate 24 is connected to the main spindle 5. The grinding wheel is offset from the center line of the workpiece W held by the tailstock 7 by the effective radius of the grinding wheel so that it contacts the cutting surface at right angles. That is, the center line of the workpiece W and the center axis of the grinding wheel are vertically different from each other and are located at right angles, and the grinding wheel is adjusted to this state and is advanced until it hits the tailstock rod 7. After confirming that, the previously known diameter of the tailstock rod 7 is reset to digital and the diameter display is digitally displayed.
Then, the finished dimensions are digitally reset, and grinding is performed by sequentially automatically making cuts until the finished dimensions are digitally displayed. When surface grinding is performed next, the axis of the grinding wheel and the center line of the workpiece W are aligned so that they face each other, and furthermore, in order to stop the rotation of the main shaft 5, the drive communication is cut off by the clutch mechanism 8. The index plate 10 is clamped and tightened between the clamping pieces 13 and 13' to fix the main shaft, and the finished dimensions of the workpiece W are reset and displayed digitally in the same manner as described above, and the finished dimensions are sequentially adjusted. If surface grinding is performed until the depth of cut is reached, and then a plurality of surface grinds are performed on the workpiece W after surface grinding, the index scale 11 of the index plate 10 provided on the spindle 5 and the display provided on the headstock 3. After indexing by the line 12, it is clamped and fixed by the clamping pieces 13, 13' in the same manner as described above.

After the grooving grinding wheel 28 attached to the upper grinding wheel shaft 22 is positioned at the top facing the center line of the workpiece W, the outer diameter of the workpiece and the finishing depth of the groove are digitally reset. In the same manner as described above, the clamping and tightening rotation of the workpiece W is stopped and fixed by the clamping pieces 13 and 13', and the workpiece W is rotated by the drive of the motor 30, and the table 2 is moved to sequentially form grooves of the finishing depth in the workpiece W. It is used for processing.

精度がよい等の効果がある。 As mentioned above, the present invention is a grinding machine equipped with two shafts, and even after cylindrical grinding is completed, the drive of the main shaft 5 is disengaged via the clutch mechanism 8, and the drive of the main shaft 5 is further fixed using a clamp mechanism. Therefore, by changing the position of the cup wheel grinding wheel during cylindrical grinding, surface grinding can be performed using the same grinding wheel, or grooving can be performed using the upper grooving wheel, with the workpiece in its original state. The work can be streamlined without the hassle of replacing with another grinder, unlike the conventional grinding machine for flattening or grooving. Further, since the next processing is performed in the processed state, there are no twists and turns, and there are advantages such as accuracy and precision.
