摘要： PURPOSE:To apply the fine thrust to a wheel turning spindle so as to improve the finish grinding of a curved surface, by providing a guide post, connected to a cylinder device, parallelly to the wheel turning spindle movably supported in the axial direction and connecting the turning spindle and said post. CONSTITUTION:Mounting a tapered shank 2a of a center shaft 2 to a main spindle tapered hole of a numerically controlled milling machine, after a housing 1 is turn locked by fixing a turn lock bar 20 to a headstock, if a main spidle of the milling machine is rotated, a wheel holder 7 is rotated through a wheel turning spindle 5 and a universal joint 8. Next, pressurized oil is supplied to a cylinder 15 from a hydraulic power unit 17 while moving said main spindle by numerical control along the surface contour shape of a work 22. Then in accordance with a pressure difference between a head side chamber 15b and a rod side chamber 15c, fine thrust moves a guide post 11 to be lowered through a piston 15a, moving also the wheel turning spindle 5 to be lowered through a connecting arm 13, thus a wheel 9 results to be pressed to the work 22 by the fine thrust.

摘要： PURPOSE:To perfectly automate grinding work by obtaining the difference between the measured value of the dimension of a work and the aimed value of the dimension and calculating the number of times of repetition of cutting and the proper cutting amount by using a computer. CONSTITUTION:A table 5a, cross rail 5b, and a working head 5c are NC-controlled in the X, Y, and Z-axes directions by an NC apparatus 1. A measurement head 5d is controlled in the Z-axis direction independently from the working head 5c. A microcomputer 4 calculates grinding length from the dimension of a material and the aimed value through receiving a start signal, and determines the cutting amount and number of times of cutting-in and grinding work is started by the instruction of the NC apparatus 1. When the number of times of repetition becomes zero, the dimension of the work is measured by the measurement head, and the cuttin-in amount and the number of times of cutting-in are determined again from the difference from the aimed value, and grinding is performed. The above-described operation is repeated until the error from the aimed value becomes within a prescribed value.

摘要： PURPOSE:To permit the groove and the vertical surface works for a large-sized work by installing a grindstone which can be fixed in turn at an arbitrary position and revolution-driven, onto a body which can be installed onto the main shaft of a milling machine for versatile use. CONSTITUTION:A body 1 is equipped with a tapered chank 1a which can be fitted onto the main shaft of a milling machine for versatile use. An arm 3 driven through a worm 5 is revolved by a clamp screw 7. An air motor 8 and a grindstone 19 are rotatably supported onto the arm 3. With such constitution, the groove and the vertical surface works for a large-sized work can be executed simply in the utilization of the three dimensional feed operation of the milling machine for versatile use.

摘要： PURPOSE:To prevent deterioration of grinding accuracy due to the tilt of a grinding wheel spindle and prevent deflection of the grinding wheel spindle by installing a grindstone directly onto the output rotary shaft of an air turbine and keeping the span of a bearing sufficiently long for the total length of the grindstone. CONSTITUTION:A sun gear 6 is fixed onto a shaft 1 having a tapered shank 1a, and a planetary gear 8 is engaged with the gear 6 and an internal gear 7 at the same time, and the gear 8 is rotatably supported by a pin 8a planted onto a cam member 4. A grinding wheel spindle 12 is supported onto a housing 10 through a bearing 13 and is equipped with a grindstone fitting part 12a at the top edge, and a grindstone 19 is fitted. An air turbine 14 is fixed directly onto the grinding wheel spindle 12. When the gear 6 revolves with the shaft 1, the gear 8 revolves, and the cam member 4 performs elevation movement, guided by an outer cylinder member 2, through the revolution, and the grindstone 19 performs elevation movement. As the turbine 14 revolves, the grindstone 19 performs planetary movement and executes two dimensional shaping grinding.
