Slidable boring tool with fine adjustment

A method for reducing tool chatter, comprising:

• providing a boring tool assembly including a body adapted and configured to be driven by a baring machine, a cutting tool holder adapted and configured to be retained by the body, and a cutting tool adapted and configured to be held by the cutting tool holder, and a separable member and a spring;
• biasing the separable member against one of to body or the cutting tool holder by the, spring;
• and
• placing the other end of the spring in contact wit the other of the body for the cutting tool holder.

A method for adjusting the position of a cutting tool holder for boring holes, comprising:

• providing a boring tool having a rotational axis and including a cutting tool holder slidable in a first direction and an adjustment member, to adjustment member being slidable in a second direction at least partly orthogonal to the rotational axis, wherein the second direction is different than the first direction;
• sliding the adjustment member in the second direction;
• coupling the movement of the adjustment member to the movement of the cutting tool holder;
• and
• sliding the cutting tool holder in the first direction by said sliding the adjustment member.

An apparatus for machining a feature with a boring machine, comprising:

• an adjustable position tool holder for holding a cutting tool;
• a slidable adjustment member for adjusting the position of said tool holder and slidably coupled to said tool holder;
• a coupling element for coupling the tool holder to the boring machine;
• said tool holder and said adjusting member being slidably coupled to said coupling element;
• and
• means for biasing said coupling element relative to said tool holder for providing a frictional force which resists motion of said tool holder relative to said coupling element;
• wherein said coupling element is adapted and configured to rotate about an axis, said tool holder is slidable relative to said coupling element in a fist direction at least partly orthogonal to the axis, said adjustment member is slidable relative to said coupling element in a second direction different than the first direction, and said tool holder is adapted and configured to slide in the first direction in response to sliding of said adjustment member in the second direction.

An apparatus for machining a feature with a boring machine, comprising:

• an adjustable position tool holder for holding a cutting tool;
• a coupling element for coupling the tool holder to the boring machine, said tool holder being slidable relative to said coupling element in a first direction;
• a slidable adjustment member slidably coupled to said coupling element and slidable in a second direction, said adjustment member having an external surface adapted and configured to be externally actuated;
• wherein said tool holder, said coupling element and said adjustment member are adapted and configured such that said tool holder slides in the first direction in response to sliding of said adjustment member in the second direction, and said tool holder slides by a first amount in response to sliding of said adjustment member by a second amount, the first amount being less than the second amount.

A method for adjusting the position of a cutting tool holder for boring holes, comprising:

• providing a boring tool having a rotational axis and including a cutting tool holder slidable in a first direction and an adjustment member, the adjustment member being slidable in a second direction at least partly orthogonal to the rotational axis;
• sliding the adjustment member in the second direction;
• coupling the movement of the adjustment member to the movement of the cutting tool holder, a surface of the adjustment member being in contact with a surface of the cutting tool holder;
• and
• sliding the cutting tool holder in the first direction by said sliding the adjustment member.
