Abstract
A cutting head for a rotating cutting tool for metal cutting operations. The cutting head has an axially adjustable cartridge which is an integral single piece. A slit divides the cartridge into a clamping portion and a main body portion, the clamping portion being resiliently connected to the main body portion. An insert pocket for retaining a cutting insert is formed by a widening of the slit so that the cutting insert is securely retained in the insert pocket between the main body portion and the clamping portion.

A cutting head for mounting slidably on a tool shank of a rotary cutting tool for metal cutting operations having an axis of rotation, the cutting head comprising a housing having a recess with an axially adjustable cartridge slidably secured therein, the recess having a base and three sidewalls extending uprightly and axially from the base, two of the sidewalls being parallel and adjacent sidewalls being normal to each other;
- the cartridge comprising an integral single piece, having top and bottom opposing parallel surfaces and a peripheral side surface extending therebetween, a slit, extending between two opposing lateral surfaces of the peripheral side surface, extends from the top surface towards the bottom surface dividing the cartridge into a clamping portion and a main body portion, the clamping portion being resiliently connected to the main body portion;
- an insert pocket for retaining a cutting insert is formed by a widening of the slit at a region opening out to the top surface, the cutting insert being securely retained in the insert pocket between the main body portion and the clamping portion.
A cutting head comprising:
- a housing having a recess provided therein, the recess having a base and three sidewalls extending uprightly and axially from the base, two of the sidewalls being parallel and adjacent sidewalls being normal to each other;
- and
- a cartridge secured in the recess, and comprising:
- an integral single piece having top and bottom opposing parallel surfaces and a peripheral side surface extending therebetween;
- a slit extending between two opposing lateral surfaces of the peripheral side surface and also extending from the top surface towards the bottom surface dividing the cartridge into a clamping portion and a main body portion, the clamping portion being resiliently connected to the main body portion;
- and
- an insert pocket formed by a widening of the slit at a region opening out to the top surface.
A cutting head comprising:
- a housing having a recess provided therein;
- and
- a cartridge secured in the recess, and comprising:
- an integral single piece having top and bottom opposing parallel surfaces and a peripheral side surface extending therebetween;
- a slit extending between two opposing lateral surfaces of the peripheral side surface and also extending from the top surface towards the bottom surface dividing the cartridge into a clamping portion and a main body portion, the clamping portion being resiliently connected to the main body portion;
- and
- an insert pocket formed by a widening of the slit at a region opening out to the top surface;
- wherein the cartridge is axially adjustable by means of an adjusting screw passing through an adjusting through hole in the housing and threadingly engaged with an axially directed threaded adjusting bore in the main body portion.
A cutting head comprising:
- a housing having a recess provided therein, the recess having a base and three sidewalls extending uprightly and axially from the base, two of the sidewalls being parallel and adjacent sidewalls being normal to each other;
- and
- a cartridge secured in the recess, and comprising:
- an integral single piece having ton and bottom opposing parallel surfaces and a peripheral side surface extending therebetween;
- a silt extending between two opposing lateral surfaces of the peripheral side surface and also extending from the ton surface towards the bottom surface dividing the cartridge into a clamping portion and a main body portion, the clamping portion being resiliently connected to the main body portion;
- and
- an insert pocket formed by a widening of the slit at a region opening out to the top surface;
- wherein the cartridge is held in abutment with two of the three sidewalls by a biasing member.
A rotary metal cutting tool comprising:
- a tool shank having an axis of rotation;
- at least one cutting head comprising:
- a housing having a recess provided therein, the recess having a base and three sidewalls extending uprightly and axially from the base, two of the sidewalls being parallel and adjacent sidewalls being normal to each other;
- and
- a cartridge secured in the recess, and comprising:
- an integral single piece having top and bottom opposing parallel surfaces and a peripheral side surface extending therebetween;
- a slit extending between two opposing lateral surfaces of the peripheral side surface and also extending from the top surface towards the bottom surface dividing the cartridge into a clamping portion and a main body portion, the clamping portion being resiliently connected to the main body portion;
- and
- an insert pocket formed by a widening of the slit at a region opening out to the top surface;
- and
- a cutting insert retained in the insert pocket between the main body portion and the clamping portion;
- wherein the housing is secured to the tool shank.
