Abstract
According to one implementation, an attachment for a machining apparatus includes: a copying guide in a machining apparatus side and an air supply passage. The copying guide has a through hole for passing a tool through. The copying guide is contacted to a copying mold placed in a workpiece side. The copying guide is attached to a spindle holding and rotating the tool. The air supply passage is adapted to supply air ejected toward the workpiece side through a clearance between the tool and the through hole.
Claims25
An attachment fora machining apparatus, comprising:
- a copying guide on a machining apparatus side, the copying guide having a cylindrical part forming a first through hole for passing a tool through, the copying guide being contacted with a copying mold placed on a workpiece side, the copying guide being attached to a spindle holding and rotating the tool;
- and
- an air supply passage adapted to supply air ejected toward the workpiece side through a clearance between the tool and the first through hole, wherein the clearance between the tool and the first through hole is arranged such that chips generated by the tool are blown away in a direction of air injection through the clearance while the tool is engaged with a workpiece, wherein the chips are blown away to a side of the workpiece that is opposite to the workpiece side, and
- wherein the copying guide further comprises a second through hole that opens toward an outside of the copying guide and defines a portion of the air supply passage that is configured for coupling with an air supply hose.

- a copying guide on a machining apparatus side, the copying guide having a first through hole for passing a tool through, the copying guide being contacted with a copying mold placed on a workpiece side, the copying guide being attached to a spindle holding and rotating the tool;
- and
- an air supply passage adapted to supply air ejected toward the workpiece side through a clearance between the tool and the first through hole,
- wherein the copying guide includes:
- a first guide for positioning the tool in a tool diameter direction of the tool, the first guide contacting with the copying mold in the tool diameter direction;
- and
- a second guide for positioning the tool in a tool axis direction of the tool, the second guide contacting with the copying mold in the tool axis direction,
- wherein the first guide has a cylindrical portion that receives the tool therethrough and has a distal free end, wherein the first through hole is formed in the cylindrical portion, wherein the second guide comprises a disk portion that extends radially out from an exterior of the cylindrical portion, with the disk portion having a distal side for contact with the copying mold and a diameter greater than an external diameter of the cylindrical portion at a level along a diameter of the tool defined by a proximal side of the disk portion, wherein the clearance between the tool and the first through hole is arranged such that chips generated by the tool are blown away in a direction of air injection through the clearance while the tool is engaged with a workpiece, wherein the chips are blown away to a side of the workpiece that is opposite to the workpiece side, and
- wherein the copying guide further comprises a second through hole that opens toward an outside of the copying guide and defines a portion of the air supply passage that is configured for coupling with an air supply hose.
