Milling cutters

Claim 2

A milling cutter comprising: a. a body, b. at least one shoe adjustably secured to said body with a first screw means passing through the shoe into said body, c. a cutting insert located in said shoe, and d. adjustment means for adjusting the position of the shoe along a direction of movement with respect to the body to vary the extent of projection of the cutting insert from the body, e. said adjustment means including a wedge member and rotatably mounted second screw means, f. said wedge member being disposed between opposing surfaces located on said body and said shoe, g. said second screw means being adapted to move the wedge member longitudinally of the screw means when the screw means is rotated whereby the shoe and insert located on the shoe are moved transversely of the second screw means by wedge action against the securing action of the first screw means.

Claim 3

A milling cutter as defined in claim 1 wherein the wedge member has a wedge face inclined at an angle of less than about 12* to the general longitudinal axis of the wedge member.

Claim 4

A milling cutter as defined in claim 1 wherein the wedge member has a wedge face disposed an an inclined angle within the range of about 5* to about 10*.

Claim 5

A milling cutter as defined in claim 1 wherein said wedge member includes a threaded bore and the axis of the second screw means is parallel to the general longitudinal axis of movement for the wedge member, said second screw means being disposed within said threaded bore in a manner effective to place the screw means under compression.

Claim 6

A milling cutter as defined in claim 4 wherein the axis of the screw lies in the median plane of the shoe.

Claim 7

A milling cutter as defined in claim 5 wherein said cutting insert abuts a supporting face of said shoe and said supporting face lies in said median plane.

Claim 8

A milling cutter as defined in claim 1 wherein the second screw means has a fine pitch and includes an anti-vibration holding insert composed of plastic material.

Claim 9

A milling cutter as defiNed in claim 1 wherein said opposing surfaces are inclined in a direction effective to retain the wedge member between the shoe and the body when not causing a wedging force to be applied to the shoe.

Claim 10

In a milling cutter having a body, at least one shoe adjustably secured to said body with screw holding means, a cutting insert located in said shoe, and adjustment means for adjusting the position of said shoe along a direction of movement with respect to the body to vary the extent of projection for the cutting insert from the body, said adjustment means comprising: a. a wedge member having an inclined surface b. said wedge member being disposed between opposing faces located on said body and said shoe of the milling cutter, c. said wedge member being movable along an axis that is transverse to the direction of movement for the shoe, and d. means for effecting movement of the wedge member in said transverse direction, e. said inclined surface of the wedge member being operatively associated with one of the opposing faces so that as the wedge member is moved along its axis of movement, the shoe is moved along said direction of movement for the shoe, f. said screw holding means includes first clamping means adjustably securing the shoe to the body with a screw means that passes through the shoe into the body and second clamping means holding the cutting insert in said shoe, g. said wedge action of the wedge member being effected against the clamping forces of said first and second clamping means.

Claim 11

In a milling cutter having a body, at least one shoe adjustably secured to said body with screw holding means, a cutting insert located in said shoe, and adjustment means for adjusting the position of said shoe along a direction of movement with respect to the body to vary the extent of projection for the cutting insert from the body, said adjustment means comprising: a. a wedge member having an inclined surface b. said wedge member being disposed between opposing faces located on said body and said shoe of the milling cutter, c. said wedge member being movable along an axis that is transverse to the direction of movement for the shoe, and d. means for effecting movement of the wedge member in said transverse direction, e. said inclined surface of the wedge member being operatively associated with one of the opposing faces so that as the wedge member is moved along its axis of movement, the shoe is moved along said direction of movement for the shoe, f. said screw holding means includes first clamping means adjustably securing the shoe to the body with a screw means that passes through the shoe into the body and second clamping means holding the cutting insert in said shoe, g. said wedge action of the wedge member being effected against the clamping forces of said first and second clamping means.

Claim 12

Adjustment means as defined in claim 9 wherein the wedge member is contiguous to the surfaces formed in a shaped recess within the body, said recess being formed between said opposing faces.

Claim 13

Adjustment means as defined in claim 9 wherein one of the opposing faces is inclined and is contiguous to the inclined surface of the wedge member.

Claim 14

Adjustment means as defined in claim 11 wherein said inclined opposing face is disposed on the shoe.

Claim 15

Adjustment means as defined in claim 9 wherein said wedge member has a partially cylindrical form and includes an inclined face which interrupts a portion of the peripheral surface of the wedge member.

Claim 16

Adjustment means as defined in claim 9 wherein said wedge member includes a threaded bore and said movement effecting means includes a screw means accommodated in said threaded bore and having a length effective for the end of the screw means to abut against said body.
