  • Patent number: 8851961
    Abstract: In one aspect, the invention is directed to a sharpener for sharpening a corner edge of a snow travel member, which may be, for example, a ski or a snowboard. The corner edge is between a bottom face and a side face of the snow travel member. The sharpener includes an angle adjustment mechanism to adjust the angle between surfaces on the sharpener that support the bottom face and side face of the snow travel member, in order to accommodate different snow travel members, that may have different angles between their bottom face and their side face. For example, the angle adjustment member may be capable of adjusting the angle between a bottom face orienting surface on the sharpener and a side face orienting surface on the sharpener between a range of angles. The range of angles may be, for example, a range from 85 degrees and 90 degrees.

  • Publication number: 20130324014
    Abstract: Apparatus and method for sharpening a cutting tool, such as but not limited to a kitchen knife. In accordance with some embodiments, a flexible abrasive disk is adapted for rotation about a central axis at a selected rotational velocity. Centripetal forces imparted to the disk during rotation urge the disk to a neutral position in which an outer peripheral portion of the disk is extended toward a selected plane. A housing adjacent the flexible disk has a guide slot with a guide surface at a selected bevel angle with respect to the selected plane. The guide surface is adapted to facilitate presentation of a cutting tool in contacting engagement against the disk. The cutting tool is presented at the selected bevel angle to induce curvilinear displacement of the flexible disk during sharpening of a cutting edge that extends along a side of the cutting tool.

  • Publication number: 20120270479
    Abstract: A grinding platform with an axis of rotation that is on the plane of the abrasive when used with belt grinders and on the plane that is vertical and tangent to the curvature of the abrasive when used with wheel grinders; such grinder having an angle gauge and possibly a vernier scale that allow for accurate determination of the angle of the tool rest in relation to the grinding surface. The grinding platform can also be continuously adjusted horizontally to compensate for wheel wear.

  • Patent number: 6991519
    Abstract: A computer controlled grinding machine grinds a cylindrical region and an annular shoulder of a rotatable workpiece. Relative movement is effected between the workpiece and a grinding wheel along a line of action which subtends an angle of approach of less than 90 degrees to the Z axis of rotation of the workpiece. Such an angle of approach enables the wheel to grind the annular shoulder of the workpiece simultaneously with grinding the cylindrical portion.

  • Patent number: 6848971
    Abstract: An electronic hollow grinder bevel angle indicator wherein a microprocessor calculates the grinding bevel angle that will be obtained when a tool is placed flat upon a tool rest and presented to the periphery of a rotating grinding wheel. The calculated bevel angle is the acute angle of intersection between the tool rest plane and a plane tangent to the grinding wheel periphery at the line of intersection between the grinding wheel periphery and the tool rest plane. The microprocessor also calculates the air-gap between the tool rest and grinding wheel, and warns the operator when the air gap exceeds a specified safety threshold.

  • Patent number: 6409575
    Abstract: An apparatus main body has a surface plate, a vertical shaft and an arm coupled to the vertical shaft such that it can move in the vertical direction. A spline shaft is attached to the arm such that it can move in the vertical direction. A keeper for holding a workpiece is attached to the lower end of the spline shaft. A reference position sensor for detecting the position of the top surface of a reference base as a reference position and a workpiece dimension sensor for detecting the position of the top surface of the keeper as a position associated with a dimension of the workpiece are attached to the arm. During a process on the workpiece, the absolute dimension of the workpiece is recognized based on information detected by the sensors, and the processing operation is controlled such that the dimension will become a desired value.

  • Patent number: 6234869
    Abstract: The record of changes in the size of a workpiece, which is measured by a gage head during grinding, is graphed on a color LCD of a control part. It is therefore possible to know if there is an abrupt change or no change in the size of the workpiece during the grinding just by looking at the graph. Thus, the sharpness of a grinding wheel can easily be judged during the grinding.

  • Patent number: 5679053
    Abstract: In a method and apparatus for grinding a workpiece, a rotating workpiece and a rotating grinding wheel are relatively moved toward and away from each other, and at least first and second grinding steps are performed at high and low infeed rates, respectively. Further, back-off grinding is performed between the first and second grinding steps. A target workpiece diameter to be obtained at the end of the back-off grinding is first provided. During the rough grinding, prediction is repeatedly performed to obtain a workpiece diameter which would be obtained at the end of the back-off grinding if the back-off grinding were started instantaneously. The workpiece diameter is predicted taking account of a delay in the movement of the grinding wheel. The back-off grinding is started when it is judged that the predicted workpiece diameter becomes equal to the target workpiece diameter.
