Abstract: A method for manufacturing a rotary tool for chip removing machining with at least one chip flute that extends in the longitudinal direction of the tool. The method involves preparing a mixture of a cemented carbide, cermet or ceramics powder and a carrier, such as a polymer, and placing the mixture in an extruding machine. The mixture is extruded in a feed direction by means of a die to form the diameter of the mixture body. The mixture body passes against a chisel which forms a chip flute in the outer periphery of the mixture body by chip-removing machining. When the chisel is displaced away from the mixture body, a non-fluted shaft portion is formed. By rotating the mixture body while contacted by the chisel, a helical chip flute can be formed. Alternatively, the body could be twisted after a straight flute has been formed, whereupon the flute becomes helical.

Abstract: A cutting bit includes a body having a front surface and a side surface, the side surface including a shoulder below the front surface and extending substantially perpendicular to a central axis of the body, and a ring that is harder than the body attached to the body at a front surface of the shoulder. Wear life of the cutting bit is enhanced by maintaining particular dimensional relationships regarding the position of the ring on the body, and the diameter of portions of the body.

Abstract: A hollow sleeve is mounted in a hole of a holder block to receive a rotary cutter bit. The sleeve includes a front flange and a shank extending rearwardly from the front flange and defining a longitudinal axis. The shank includes an outer periphery having a radially stepped configuration, wherein an outer surface of the shank includes a plurality of axially adjacent surface sections that become successively smaller in cross-section in a direction away from the flange. Each surface section occupies one-third of the hole length. Each surface section has longitudinally spaced front and rear ends, wherein a portion of each surface section situated between its front and rear ends is spaced farther from the axis than are the front and rear ends. Each surface section has a generally longitudinally extending groove formed therein.

Abstract: A cutting tool for attachment to the leading area of a base is provided. The cutting tool includes a holder base having two substantially parallel cutting teeth extending from the holder base, the cutting teeth each having a cutting edge and an opening between the teeth. The cutting teeth define first and second cutting paths. The cutting teeth impact and cut asphalt shingles, and funneling surfaces of the teeth funnel the cut shingle material toward and through the opening, and into the path of the rear cutting member which cuts the material a second time. Thus, asphalt shingles are processed more efficiently, thereby creating less frictional heat and avoiding melting of the asphalt shingles.

Abstract: A mobile drilling rig includes a platform mounted on drivable ground supports. Drilling equipment is disposed on the platform and is operated by a power system that includes hydraulic pumps, a screw type air compressor, and a motor for driving the pumps and the compressor. A gearbox is common to the hydraulic pumps and the air compressor and includes an intermeshing gear arrangement for transmitting an inputted power from the motor to the pumps and the compressor. Compressed air from the compressor travels to an air reservoir in which compressor oil is separated from the air. The compressor oil is conducted to an oil inlet of the gearbox and is circulated through the gearbox to an oil outlet of the gearbox which communicates with an air inlet of the compressor.

Abstract: A machine spindle includes a casing and a drawbar assembly disposed in the casing for clamping a tool in place. The drawbar assembly includes a front drawbar having a tool clamp, and a rear drawbar movable rearwardly under a spring force for pulling the front drawbar rearwardly to activate the clamp. A rearward force from the rear drawbar is transmitted to the front drawbar by a wedge arrangement that includes multiple pairs of wedges that have cooperative sliding surfaces that make surface contact (as opposed to line contact) with one another. The cooperative sliding surfaces are configured to provide an amplified rearward force against the front drawbar during a final stage of clamping.
