Scheme is more specifically further, and near top end on guiding groove, be provided with anticreep plate, the width of anticreep plate is greater than the width of guiding groove.As seen from the above, anticreep plate can prevent in process, and sand belt slides from rubbing head.
Preferably, drive unit comprises the travel mechanism that rubbing head is moved up and down.As seen from the above, by moving up and down of rubbing head, blind hole inwall is processed.
More particularly, Workpiece rotating device, on the Workpiece rotating device that workpiece can be fixed thereon, and rotates under Workpiece rotating device drives.As seen from the above, utilize the processing that the rotation of workpiece is carried out circumferential wall, rubbing head can without the need to rotating.
More specifically, drive unit comprises the shaker mechanism that rubbing head is shaken.As seen from the above, utilize the shake of rubbing head, effectively reduce the Rp value of bore area, make bore area there is not larger projection, make sand belt not easily be damaged simultaneously.
Preferably, the top of guiding groove is provided with two guide wheels, enters guiding groove and draw from guiding groove for guiding sand belt respectively.As seen from the above, utilize guide wheel, sand belt can enter guiding groove smoothly and can draw smoothly from guiding groove.
More particularly, feed mechanism also comprises strainer, and strainer is connected with induction conductivity.As seen from the above, utilize strainer, sand belt can remain on tensioned state, is conducive to the work of rubbing head.
More specifically, drive unit comprises the mechanism driving feed table or receive rotation of disc.When being the sand belt wearing and tearing on rubbing head top, can utilizing drive unit that the sand belt of feed mechanism is moved and make the unused portion of sand belt move to operating position.
