Abstract
An insert holder includes a head having ridge teeth, and an insert seat plate seated on the head such that ridge teeth thereof mesh with the ridge teeth of the head. The plate forms a V-shaped recess in which a cutting insert is to be received. The recess thus defines a position of support for the insert. A bisector of the V-shaped recess extends parallel to the ridge teeth. The insert seat plate is adjustable in the direction of the bisector (e.g., by individually deployable spacer plates of different thickness) to adjust the position of support defined by the V-shaped recess.
Claims15
An insert holder adapted to hold a cutting insert for chip removing machining, comprising:
- a head including a first surface having a first ridge tooth arrangement;
- an insert seat plate having a second surface seated on the first surface, the second surface having a second ridge tooth arrangement meshed with the first ridge tooth arrangement, the insert seat plate forming a recess which is generally V-shaped as the insert seat plate is viewed in a direction perpendicular to the second surface, the V-shape defining an apex, the recess adapted to receive a cutting insert and defining a position of support therefor, the recess defining a bisector extending through the apex substantially parallel to the first and second ridge tooth arrangements;
- and
- adjusting means for adjusting the insert seat plate in the direction of the bisector, wherein the position of support defined by the V-shaped recess is correspondingly adjusted.

An insert holder adapted to hold a cutting insert for chip removing machining, comprising:
- a head including a first surface having parallel first ridge teeth and first and second threaded holes;
- a support surface upstanding from the first surface and including a third threaded hole;
- an insert seat plate having a second surface seated on the first surface, the second surface having parallel second ridge teeth meshed with the first ridge teeth, the insert seat plate forming a V-shaped recess adapted to receive a cutting insert and defining a position of support therefor, the recess defining a bisector extending substantially parallel to the first and second ridge teeth;
- a first screw receivable in the first threaded hole for securing the insert seat plate to the head;
- a second screw receivable in the second threaded hole for securing an insert to the head;
- a third screw receivable in the third threaded hole for securing an upstanding portion of the insert seat plate to the upstanding portion of the holder;
- and
- exchangeable spacer plates of different thickness individually deployable between the support surface and the insert seat plate for adjusting the insert seat plate in the direction of the bisector, wherein the position of support defined by the V-shaped recess is correspondingly adjusted, each spacer plate including a recess through which the third screw extends, the groove being open at one end thereof to enable the deployed spacer plate to be removed and replaced while the insert seat plate remains connected to the head.

An insert holder adapted to hold a cutting insert for chip removing machining, comprising:
- a head including a first surface having a first ridge tooth arrangement;
- an insert seat plate having a second surface seated on the first surface, the second surface having a second ridge tooth arrangement meshed with the first ridge tooth arrangement, the insert seat plate forming a V-shaped recess adapted to receive a cutting insert and defining a position of support therefor, the recess defining a bisector extending substantially parallel to the first and second ridge tooth arrangements;
- and
- adjusting means for adjusting the insert seat plate in the direction of the bisector, wherein the position of support defined by the V-shaped recess is correspondingly adjusted;
- the holder further including a support surface upstanding relative to the first surface;
- the adjusting means comprising exchangeable spacer plates of different thickness individually deployable between the support surface and the inset seat plate, wherein the spacer plates are exchangeable with one another while the insert seat plate remains connected to the head.
