摘要： PROBLEM TO BE SOLVED: To provide a high-resolution code disk for encoder that can detect absolute positions, a method of manufacturing a metallic mold used for producing the code disk, and so on.
SOLUTION: The code disk for encoder formed by using a transparent substrate is provided with a plurality of tracks formed on the transparent substrate and having different patterns on their surfaces and inter-track areas provided among the tracks and having different heights from those of the surfaces of the tracks. The method of manufacturing the metallic mold used for producing the code disk includes a step of forming tracks having flat surfaces on a first material, a step of forming inter-track areas having different heights from those of the flat surfaces of the tracks among the tracks, and a step of forming different patterns on the flat surfaces of the tracks. The method also includes a step of plating the patterns of the first material, and a step of obtaining the metallic mold by removing the plated layer from the first material.

摘要： PROBLEM TO BE SOLVED: To provide a code plate for encoder capable of detecting an absolute position with high resolution and manufacturing method and the like for its die.
SOLUTION: The code plate for encoder is provided with a first track constituted of a transparent base plate, a V-shape part with V-shape cross section and reflecting light and a flat part transmitting light placed on the surface of the transparent base plate and having a first pattern of which the pitch between the V-shape parts varies along the direction perpendicular to the V-shape part, and a second track constituted of a V-shape part with V-shape cross section and reflecting light and a flat part transmitting light placed on the surface of the transparent base plate and having a second pattern of which the pitch between the V-shape parts is constant along the direction perpendicular to the V-shape part. The region between the first track and the second track is projecting to the thickness direction from the surface where each track is provided.

摘要： PURPOSE:To materialize highly accurate machining of a small hole without a reversed taper by forming a wheel spindle into a thick-end horn shape, and making the contour in the axial direction on the outer periphery of the wheel spindle a straight line when a wheel is deflected due to a machining force at the time of machining a small hole. CONSTITUTION:A wheel spindle 1 is formed into a thick-end horn shape and abrasive grains 2 are deposited on it by means of a plating metal 3, and the spindle 1 is held by a large diameter holding part 1a in a cantilever type. This horn shaped contour is designed in such a way that when the wheel spindle is deflected due to a machining force at the time of machining, the contour in the axial direction on the outer periphery of the wheel spindle 1 just agrees in parallel with the axis of the hole 10a being machined of a workpiece 10, i.e., in the vertical direction. Thereby, highly accurate machining of a small hole without a reversed taper can be carried out, without causing the clogging of foreign matter at the time of machining a small hole of a blanking type die by means of this wheel while preventing an accident such as the breakage of a punch, etc.
