Abstract
A milling tool having multiple parts to facilitate tool change in which detachable metal cutting edges are mounted on an annular ring supported from an adapter mounted on the milling machine. The adapter includes a support plate for supporting the cutting ring and a pilot member which is biased against the cutting ring to insure that it is centered relative to the axis of rotation.
Claims10
A milling tool comprising;
- an annular cutting tool, a support for said cutting tool including first and second members rotatable as a unit about a common axis, biasing means continuously urging said first and second members axially apart, said annular cutting tool being attachable to one of said members, means for attaching said cutting tool to said one of said members, the other of said members and said cutting tool including complementary annular guide surfaces engageable with each other to maintain said cutting tool concentric to said axis upon movement of said annular cutting tool relative to said one of said members.
A milling tool comprising;
- a tool support including a first member adapted for connection to a rotatable drive member, a second member member connected to said first member for rotation therewith and axial movement relative thereto, a cutting tool attachable to said first member, said cutting tool and said second member including complementary guide surfaces in engagement with each other, biasing means urging said first and second members apart to maintain said guide surfaces continuously in engagement with each other to maintain said cutting tool concentric to said axis, and means connecting said tool to said first member against the action of said biasing means.
