摘要： A hole making position control unit for a hole making machine suitable for making rivet holes and bolt holes in shaped steel. This control unit mainly comprises a marked plate having marks thereon, a photoelectrical apparatus for detecting the mark and a hole making head interlocked with the photoelectrical apparatus, and controls the action of the hole making head in accordance with the arrangement of the marks, which are arranged at the positions corresponding to the centers of holes to be made and to the turning positions of the moving direction of the hole making head. Each mark has a width to be detected in the detecting direction of the photoelectrical apparatus, so that during the detection of the mark the hole making head is instructed to decelerate, and when the detection is finished the hole making head is instructed to stop.

摘要： A metal-sawing machine includes a rocking system whereby the saw blade is enabled to rock in a cutting plane in which the work is cut, wherein the rocking motion is controlled so as to conform to the cutting stroke, which is determined in accordance with the shape and size of the work. The machine ensures that the rocking motion of the saw blade fully participates in cutting the work unlike the known metal-sawing machines in which the rocking motion is partially wasted in cutting "air".

摘要： A method of controlling the cutting feed speed of a saw frame of a band-sawing machine or a similar machine, whereby the change of cutting resistance to the saw blade is detected as a change in pressure of an oil pressure cylinder supporting the saw frame and by transforming such change into a voltage change by means of a piezoelectric element, the flow rate of a flow control valve provided in the pressure oil discharge circuit of the oil pressure cylinder is controlled by said detected voltage or the like and thereby the cutting feed speed is changed in response to the change of cutting resistance so as to maintain the cutting resistance to the saw frame at an optimum.

摘要： A method of controlling the cutting feed speed of a saw frame of a band-sawing machine or a similar machine, whereby the change of cutting resistance to the saw blade is detected by sensing the change of load on the back of the saw blade or the change of pressure of an oil pressure cylinder supporting the saw frame and by transforming such change into a voltage change or amperage change by means of a piezo-electric element, the flow rate of a flow control valve provided at the pressure oil discharge circuit of the oil pressure cylinder being controlled by said detected voltage or the like and thereby the cutting feed speed being changed in response to the change of cutting resistance so as to maintain the cutting resistance to the saw frame at an optimum value.
