摘要： PURPOSE:To ensure the good grinding and polishing of a workpiece by providing a central control device for operating a count value upon receipt of the feed speed of the workpiece, and controlling the drive timing of a lift control device depending upon the operated count value. CONSTITUTION:A function [x = f(v)] having the feed speed (v) of a workpiece W and a count value X agreeing to the optimum drive timing of the pressing pad 18 of a counter respectively as variables, is preliminarily set up in a central control device CPU. Then, this device CPU operates the count value X when inputted with the feed speed (v) of the workpiece W, and controls the drive timing of a lift control device 22 for the pressing pad 18 due to an air cylinder or the like, using the count value. According to the aforesaid construction, the pressing pressure of a sanding belt 11 for the front and rear ends of the workpiece W can be made suitable, and this sanding belt 11 can be used for the proper grinding and polishing of the front and rear ends of the workpiece W.

摘要： PURPOSE:To remove the grinding unevenness on the surface of a work stock and to grind the work stock uniformly and beautifully by integrally linking a stepping pad and belt guide mechanism by attaching to an installation frame and forming the structure of reciprocating this frame in about the right and left direction crossed with the traveling direction of the work stock. CONSTITUTION:A crank 40 is reciprocated at the stroke of two times the eccentric amt. of an eccentric pin 39 by the driving of a driving motor 36, accordingly, an installation frame 11 is reciprocated in the right and left directions. Accordingly, an endless belt 41 is press-fitted with performing zigzag movement relatively by the composition of the right and left movement thereof and the traveling of the work stock therefor and grinding and polishing are executed on the work stock.

摘要： PURPOSE:To prevent irregular finishing of the front end edge of a work as far as possible, by sliding the position of the work detector in the fore and aft direction alternately and also making the timing controls from the ON motion of the work detector to the motion of a press member the same. CONSTITUTION:The discrimination content of a control means is fixed in advance so as to be able to drive a press member at a low pressure, by making a pressure converting device communication with a low pressure air source P1 by an air cylinder 22, in the case of one detector only being of ON detection, in the press member 18 existing at the width position bridging two detectors S1, S2. The press member 18 located on the side end edge of a work W becomes being press-fitted to the work W side at a low pressure. So, the pressure at the side end edge onto the work W becomes the optimum and the grinding in the specific thickness can be executed without causing irregular finishing. In the case of the both of two detectors S1, S2 or all of the work detections in the specific width zone including the both being ON, the air cylinder 22 is communicated to a high pressure air source P2 and it is strongly stepped by the press member, when the proper position arrives at a stepping device.

摘要： PURPOSE:To grind the side surface identically by enabling a shaping wheel of a side surface polishing unit controllably moved in the X, Y directions to be eccentrically controllably moved widthwise relative to the lift ram by a transfer unit. CONSTITUTION:A shaping wheel 72 of a polishing unit 40a controllably moved in the X, Y directions by a transfer head 18 is eccentrically controllably moved widthwise relative to the lift ram 26. In working a workpiece W even if the workpiece W is formed with outside or inside arcuate surfaces having various curvatures, the lift ram 26 is rotated 90 deg. at respective corners while traveling along respective side by causing the radius of arc to coincide with eccentricity. Thus, the side surface of rectangular frame-like workpiece can be ground identically so that the side surface grinding can be automated.
