A reaming tool includes a tool body having an axially rearward shank portion and an axially forward cutting portion, the forward cutting portion having at least one peripherally arranged cutting insert. The reaming tool also includes an inlet coolant channel formed in the tool body and an inlet opening at an axially rearward end of the shank portion. An outlet coolant channel is formed in the tool body and is in fluid communication with the inlet coolant channel, wherein the outlet coolant channel defines an outlet opening proximate to the cutting insert. In one particular aspect, at least a portion of the outlet coolant channel is non-linear. A method of making a component of the reaming tool by performing a printing operation on a substrate to form the component is also provided.

A cryogenically cooled boring tool design reduces the effect of cryogen coolant on a workpiece caused by coolant leakage and coolant exhaust. A tool body has a cartridge for holding a cutting tool insert and a coolant supply path through the tool body and the cartridge for supplying cryogenic coolant to the tool insert. A feed transfer tube connects the coolant supply path in the tool body to the coolant supply path in the cartridge. Insulating tubes line portions of the coolant supply paths in the tool body and the cartridge. The shrinkage rates of the feed transfer tube and the insulating tubes cause the press fit of the insulating tubes to tighten the seal between the insulating tubes and the feed transfer tube when cryogenic coolant flows through the supply path. The exhaust ports on the tool for boiled-off cryogen remains outside of a workpiece bore.

The present disclosure is directed toward a tooling assembly for a machine having an automatic tool changing system. The tooling assembly includes a holder, a tool body, and an internal passage defined within and extending through the holder and the tool body. The holder includes a machine interface configured to engage with a spindle of the machine. The internal passage is operable to have a coolant fluid flow within, and has a stem channel and a curved channel extending from the stem channel.

The burnishing part includes: a mandrel; burnishing rollers; a frame; an adjustment member that presses the frame axially from one end thereof to adjust the axial position of the frame with respect to the mandrel; and an elastic member that is arranged axially on the other side of the frame to support the frame. The reaming part includes: a base part that is detachably attached to the mandrel; and machining blades that are formed integrally with the base part. This results in providing a combined machining tool that is capable of machining an inner peripheral surface of a workpiece having a smaller diameter, and a machining method using the same.

A cutting tool 1 includes a cutting edge equipped with a helically curved groove 2 at a side outer periphery in the longitudinal direction, and a coolant passage pipe 3 extended internally and communicatively connected with ejection holes 4 of coolant arranged inside the groove 2 by way of a coolant passage pipe 31 branched from the coolant passage pipe 3 extended around a rotation center axis along the longitudinal direction or along the helically curved groove.

The invention relates to a single-lip deep hole drill comprising a drill head, wherein the drill head has a drill diameter, a blade and a channel for chip removal, wherein the blade extends outwards from a rotational axis up to the perimeter of the drill head, wherein the blade has a cutting surface and wherein the channel is bordered by a chip forming surface, wherein the chip forming surface has two sections such that a first section of the chip forming surface extends in the radial direction from the rotational axis up to a first diameter, a second section of the chip forming surface connects to the first section in the radial direction, the first section is positioned above the cutting surface, and the second section is positioned nearer to the cutting surface than the first section.

A chip-removing tool for deburring bores, which laterally open into a cylindrical recess for example, comprising a shaft; a cutting head with at least one cutting wedge on the circumference, said cutting wedge being paired with a flute and having a cutter, which extends in an axial direction at least in some sections, carries out a cutting process on the basis of a relative movement between the tool and a workpiece, and lies on a virtual cylindrical rotational surface with a diameter that corresponds to the nominal diameter of the chip-removing tool, and at least one cutting wedge- and flute-free surface region; at least one fluid channel closed on the cutting head side and extending through the shaft and into the cutting head; and at least one puncture channel which starts from the fluid channel and comprises an opening that lies in the cutting wedge- and flute-free surface region.

A method of machining a workpiece is provided that is capable of forming a fresh air inlet in an arbitrary position in an outer shell of a container. According to the present invention, a method of machining a workpiece is provided that includes: machining to form a round hole in a workpiece using a boring drill having a tubular end portion, the end portion provided with a flat surface and a notch, and having a blade on a side of the notch, by pressing the flat surface against the workpiece while rotating the drill to contact the blade with the workpiece.
