Abstract: A method for producing a replaceable cutting head is described. The replaceable cutting head is manufactured by extruding a blank. During extrusion of the blank, a number of helical coolant channels and a number of helical flutes are simultaneously formed. After extrusion, the flutes have a first angle of twist (D1), and the coolant channels have a second angle of twist (D2). After extrusion, the blank is sintered and then reworked to selectively adjust the first angle of twist (D1) and the pitch of the flutes. The method produces an endless blank that is capable of being parted off to a desired length without any sacrificial allowance, which provides significant material and cost savings as compared to conventional methods.

Abstract: A system for aligning a camera view and the illumination of a lighting fixture is disclosed. The system includes a camera contained with a housing and a lighting fixture that is pivotedly attached to the housing. An angle adjuster attached to a proximate end of each of the housing and the lighting fixture converts a linear movement to the adjuster into an angular adjustment of the lighting fixture with regard to an optical axis of a camera contained with the housing. In another aspect of the invention, the system of aligning a camera view and light fixture may be attached to a magnification lenswear and a focal point of the magnification lenswear may be aligned with the aligned camera view and the illumination of the lighting fixture.

Abstract: A tool head for a machine tool comprising a plurality of tool spindles with each tool spindle being rotatable about a respective tool axis. The plurality of tool spindles comprises at least a first tool spindle rotatable about a first tool axis, a second tool spindle rotatable about a second tool axis and a third tool spindle being rotatable about a third tool axis with the first, second and third tool axes being parallel to one another. The first, second and third tool spindles are arranged on the tool head whereby one of the first, second and third tool spindles faces a first direction and the other two of the first, second and third tool spindles face a second direction with the first and second directions being 180 degrees apart. The tool spindles are preferably grinding spindles on a machine for grinding bevel gear cutting tools.

Abstract: Disclosed in the present application is a sharpening apparatus and method for sharpening a cutting bit. The apparatus comprises a sharpening member and a laser for accurately positioning the cutting bit surface to be sharpened with respect to the sharpening member. The apparatus and method are particularly useful for sharpening a router or shaper bit.

Abstract: A universal blade sharpening machine is operable to securely hold and sharpen any one of multiple variously sized circular blades. The machine includes a blade-sharpening drive with an adjustable blade sharpener and also includes a universal blade holder that is rotatably powered by the drive. The blade holder includes a blade-receiving chassis that holds the blade during sharpening and is rotatable about a rotation axis of the blade holder. The chassis includes a plurality of radially spaced blade-retaining sections each associated with a respective one of the circular blades.

Abstract: A sharpening guide for use with a chisel and a grinding wheel comprising a rod having a first end and a second end, a pivot assembly carried by the first end, a tool clamp attached to the pivot assembly and movable relative to the rod and adapted to retain the chisel, a base, and a base pivot for movably mounting the rod relative to the base whereby the base pivot is adapted to be mounted adjacent the grinding wheel. A method of sharpening a tool comprising the steps of locating a tool within a tool clamp, rotating the tool clamp toward a grinding wheel about a first axis until the tool is in contact with a grinding wheel, and rotating the tool clamp about a second axis to move the tool across the grinding wheel rotationally.

Abstract: A jig intended in use to hold a set of blanks of rod-like or wire-like form during machining, said jig having a body adapted to be mounted to a drive shaft for rotation of the body about an axis of rotation, the body having an outer portion and an inner portion wherein the inner and outer portions are capable of angular displacement relative to each other, the portions having opposed faces which are concentric and which define clamping faces which in use are intended to support the set of blanks such that their central axes are substantially parallel to the axis of rotation and at least one end extends axially beyond the body.

Abstract: A fixture for holding tools to be processed in a rotational processing apparatus. The fixture includes at least one mounting rod with a plurality of spacers slidably disposed on the mounting rod. A plurality of tools are disposed about the rod, each tool being spaced from an adjacent tool by one of the spacers. A removable attachment is provided on at least one end of the rod for inhibiting the spacers from sliding off the rod. The fixture may also include first and second end plates mounted to the rod on either side of the products being finished. One or more springs may also me incorporated onto the rod between a spacer and the first or second end plates. A process for loading and using the fixture is also disclosed.

Abstract: A saw blade positioning device has two drive mechanisms and two guidance devices, which are preferably oriented at right angles in respect to each other. If a first guidance device is oriented in the radial direction of the circular saw blade by the linear guides, and the other guidance device in the circumferential direction, a desired advancement curve of the engagement member, independently of the saw blade diameter, is achieved respectively by means of the same control, or respectively the same control pulses, and of the drive mechanisms, in every radial position of the first guidance device. A mechanically robust basic structure results in addition, which makes a precise positioning possible.

Abstract: A swing grinding fixture and process for using the same is disclosed that enables a conventional surface grinder to remanufacture a machine tool cutting insert by grinding a predetermined shape into the insert. A quick clamping insert holder coupled to a slide secures the tool insert in the fixture. A precision spindle cartridge is mounted in a rigid fixture body and coupled to the slide to provide the swing motion required to generate the radius to be ground. The rigid fixture body includes a pair of micrometer adjustable stops which limit the arc through which the slide may be swung and control the flank shape ground into the insert. In an alternative embodiment, a sine plate is attached to the fixture body and is used to incline the fixture to a predetermined insert rake angle. In operation, the grinding fixture is securely mounted to the table of a surface grinder and a cutting tool insert is secured in the insert holder.

Abstract: A powered grinding tool (10) comprising a casing (16) in which is an electric motor (40) which drives a shaft (39) on which is carried a grinding wheel (20) at a work station. The tool casing has undercut slots (24) at opposite sides of its front face for automatic vertical sliding engagement with a selected one of a number of adapters (11-13), each adapter providing a location which, in use, is disposed relative to the grinding wheel so that there is correct positioning between part of an implement that said location and the grinding wheel, for said part to be worked by the wheel. The casing can have the slots (24) on at least one other of its faces to store adapters when they are not in use.

Abstract: A process and apparatus for the finish grinding of cutting blades of a cutting tool head of a granulating device for thermoplastic material in which a grinding wheel is supported for rotation about a vertical axis with a grinding surface of the grinding wheel facing upwardly and the cutting blades of the cutting tool head rest on the grinding surface of the cutting tool head under the weight of the grinding wheel. The cutting tool head is free for vertical movement and is precisely aligned with the axis of rotation of the grinding wheel. The grinding wheel is driven by a motor around a vertical axis to grind the cutting surfaces of the cutting blades and produce precision ground surfaces on the blades which are aligned in a common plane.
