The illustrated embodiment includes a front and rear feed table 1 and a left and right feed table 2 that reciprocates orthogonally to the feeding direction of the front and rear feed table 1. It is equipped with a grindstone mounting shaft 5 that rotates by receiving force via a belt 4, and separately, a circular right side of a circular intermediate grindstone 6 with a grain size of 800 and a bond degree of N8 is mounted on the right side of a circular intermediate grindstone 6 with a grain size of 800 and a bond degree of N4. whetstone 7,
Also, on the left side of the same intermediate grinding wheel 6, the grain size is 220 and the bonding degree is N5.
The circular left-hand grindstone 7' is bonded and integrated so that the outer peripheral surfaces of the grindstones 6, 7, and 7' form the same circular surface to form a rotary whetstone A, and this rotary whetstone A is attached to the above-mentioned mounting shaft. A jig 9 which is non-rotatably but replaceably fixed to the left and right feed bases 5 and holds a large number of magnetic sludge axially arranged on the left and right feed bases 2 is arranged parallel to the reciprocating direction of the left and right feed bases 2. Both ends of this jig 9 are rotatably supported by a pair of center members 10, 10' which are installed upright on the upper surface of the left and right feed table 2, and an arm 11 is stretched over one end of the jig 9. By swinging the arm 11 by a swinging device 12 provided on the left and right feed tables 2, the magnetic sludge is brought into contact with the outer peripheral surface of the rotary grindstone.

That is, in the description, first, the front and rear feed table 1 is moved to a position where the outer circumferential surface of the rotary whetstone A comes into contact with the trajectory surface of the tape contact surface of the magnetic sludge held on the jig 9, and then the rotary whetstone A is put into a rotating state. At the same time, the shaking device 12 is operated to swing the arm 11, the jig 9, and the magnetic sludge, and the left and right feed tables 2
, the magnetic sludge moves from left grinding wheel 7' to intermediate grinding wheel 6 to
Right grindstone 7 → Right grindstone 7 → Intermediate grindstone 6 → Left grindstone 7′ → Left grindstone 7′ → Intermediate grindstone 6 → Right grindstone 7 → Intermediate grindstone 6 → Intermediate grindstone 6 → Intermediate grindstone 6 contact in this order (Left and right grindstone 7 , 7' are not in contact with each other in the later stages because they wear quickly, and as the intermediate grinding wheels 6 are repeatedly used in the later stages, the intermediate grinding wheels 6 are worn out and their outer peripheral surfaces and the outer peripheral surfaces of the left and right grinding wheels 7 and 7' become on the same plane. The magnetic head tapes are moved back and forth so that the magnetic head tapes get very close to each other and are ready for the next head polishing), and the contact surfaces of a large number of magnetic head tapes, which are held side by side on the jig 9, are polished into elaborate arcuate surfaces. It is something.

Then, the next time the head is polished, the front and rear feed table 1 is shifted forward by the amount of wear of the rotary grindstone (usually 0.07 mm) so that the above-mentioned contact order is achieved, and the next head polishing operation is started.

Conventionally, this type of cylindrical polishing machine for magnetic heads was a two-step process in which a rough grinding wheel was used for polishing, then the grinding wheel was replaced, and a finishing wheel was used for polishing separately, which took twice as much time and reduced efficiency. Not only are there disadvantages such as poor performance and a limit to cost reduction, but also the process of replacing a rough whetstone with a finishing whetstone is cumbersome and inevitably results in a loss of time.

The present invention was made with the aim of eliminating such defects, and since it has the above-mentioned configuration, if it is used as described above, there is no need to replace the rough whetstone and finishing whetstone as in the past. It has an excellent effect that can fully achieve the intended purpose.
