摘要： PURPOSE:To reduce the number of passes at a flaw removing grinding process and to improve production capacity for a stainless steel sheet by controlling the rotation speed of a grinding belt to a range of 850-1150mpm at a grinding pass and in a range of 1000-2000mpm at a subsequent finish grinding pass. CONSTITUTION:The rotation speed of a grinding belt 3 is controlled to a range of 850-1150mpm at a flaw removing grinding pass and a range of 1000-2000mpm at a subsequent finish grinding pass. This method grinds a stainless steel sheet 2 with high efficiency and low surface roughness.

摘要： PURPOSE:To perform continuous operation without fouling plural marks to be cut by automatically carrying out removal of foulings sticking to a heat cutter according to a cleaning pattern previously memorized in a process for automatically cutting the plural desired marks with the heat cutter. CONSTITUTION:In an apparatus for operating a heat cutter based on desired mark data read out of a floppy disk memorizing plural mark data showing a cutting method corresponding to a prescribed mark and automatically carrying out cutting, the optimum cleaning pattern is read out of a memory memorizing plural cleaning patterns in which a metal brush for removing foulings sticking to the heat cutter in heat cutting the mark is brought into contact with the aforementioned cutter the perform relative motion. After the above-mentioned heat cutter conducts cutting operation of the mark fabric through a prescribed distance based on the aforementioned cleaning pattern, the cutter is moved to a fouling removing device composed of the above-mentioned metal brush to automatically remove the sticking foulings.

摘要： PURPOSE:To execute uniform finishing of a casting product in the finishing apparatus where a rotary grinding stone and work are moved with a control means to remove burr, etc., of the work by detecting work rate of a rotary grinding stone when the rotary grinding stone wears and adding the above detected value to movement of the rotary grinding stone to current the movement thereof. CONSTITUTION:By using the rotary grinding stone 76 arranged at front end side of a swinging arm 70 and shifting to Y direction with shift of a lifting block 60, removal of burr on upper face and circumferential side face of a work clamped with a clamping device 20 is executed. In this apparatus, control means for controlling each driving device of a clamping base table 22, clamping device 20, grinding stone table 52 and lifting block 60, detecting means for detecting worn rate of the above rotary grinding stone with a sensor and correcting means for shifting the grinding stone table 52 and the lifting block 60 according to the worn rate of this grinding stone, are provided. By this method, as the worn rate of the rotary grinding stone is detected and the correcting means for correcting the movement of the rotary grinding stone based on this worn rate is arranged, the uniform finishing can be carried out.

摘要： PURPOSE:To predict the extent of deterioration of the equipment to be measured from its initial state nondestructively with high accuracy by estimating the maximum and minimum values of the whole equipment according to the statistical distribution of extremal values of variation measurements of magnetic characteristics at optional positions of the equipment. CONSTITUTION:The deterioration of a metallic material is inspected. In this case, the body 1 and a reference test-piece 15 are applied with exciting magnetic fields of desired frequency with sine waves from exciting coils 5A and 5B, Hall elements 2A and 2B detect the values of the magnetic fields, and detection coils 3A and 3B detect the magnetic field density. Thus, a discontinuous jump of extremely small magnetism based upon a magnetic hysteresis curve and Barkhausen effect generated by the movement of a magnetic wall is measured. Consequently, physical characteristics for deciding the extent of deterioration are found at the optional positions. A regression period based upon the statistical distribution of the extremely values of measured value is used to estimate the maximum and minimum values of the physical characteristics from the measured value and the maximum value of the deterioration of the measured body 1 is estimated from a data base for the relation between the deterioration extent and characteristics of a material which is already found.

摘要： PURPOSE:To locate accurately a slab to be ground for a short time by providing a slab carrier disposed between transfer rollers, a carrier drive mechanism and a mechanism for adjusting a position of slab on the transfer rollers. CONSTITUTION:A ground slab support device 3 is constituted from a slab carrier 31, a carrier drive mechanism 32 and a slab position adjusting mechanism 33. The slab carrier 31 is disposed between transfer rollers 2 to support a slab 1 so that the slab 1 can be delivered between the slab carrier 31 and the transfer roller 2. The carrier drive mechanism 32 receives and moves vertically the slab carrier 31 to the slab plane, and travels widthwise forward and backward. The slab position adjusting mechanism 33 is mounted on a machine frame provided independently from the slab carrier 31 to adjust the widthwise position of slab 1 on the transfer roller 2. The slab 1 is located and supported by a support device 3 to repair flaws on the surface of slab 1 by a conventional traveling type grinding machine 4.
