Abstract:
The invention relates to a friction and sinking cutting tool comprising a base member (2) to which a cutting blade (20) is exchangeably clampingly fixed by means of a clamping screw and which is adjustable in terms of its radial position by an adjusting member (40) through the intermediary of an adjusting means (30). The adjusting means (30) is a cutting blade carrier extending into a recess in the base member, and the adjusting member (40) is a differential screw which is in threaded engagement with the adjusting means. Alternatively, the adjusting means (30) can be a cutting blade carrier extending into a recess of the base member and the adjusting member (40) can be a ball member or clamping member which has automatic shape fitting engagement with a complementary recess in the adjusting means such that a movement of the adjustment member causes a movement of the cutting blade (20) in the same direction. It is advantageous if at least one bore for coolant is provided leading to the cutting zone, with at least one branch bore (22) leading outwardly from the forward region of the coolant bore. With this construction coolant and lubricant can be supplied to the cutting zone.
Abstract:
A single-blade reamer is guided in a hole by means of at least one guide fillet. The guide fillet is provided with a coating of cubical boron nitride (CBN) in the region of its guide surface facing the wall of the hole. The guide fillet thus withstands heavier loads, so that the reamer is suitable in particular for the economical machining of hardened steel alloys.
Abstract:
A reamer having a single cutting blade with parallel clamping and seating surfaces seated in an anvil having converging radially outward extending planar surfaces for enhancing the clamping effectiveness of an installed anvil/cutting blade adjustably positioned radially by a pair of set screws angled to provide fine adjustment.
Abstract:
A single-blade reamer (30) is disclosed with a cutter plate having a cutter blade (5) and attached to the base body (20), and with two guide strips (6, 7) disposed at the circumference of the base body. A chip-guide device (8, 9, 10, 11) is disposed between the cutter plate or, respectively, the cutter blade (5), and the first guide strip (6) following at an angular distance relative to the cutter (5) as seen from a point of a fixed external coordinate system when the reamer (30) is rotating in a proper cutting direction and/or between the first guide strip (6) and a second guide strip (7), disposed opposite to the cutter blade (5).
Abstract:
A rotary cutting tool including an elongated generally cylindrical holder having a recess into which is fitted a disposable cutting insert. The insert is held in place by a clamping member which bears against a surface of the insert and which is attached to the holder by a clamping screw. Radial adjustment of the insert can be effected by adjusting screws which have camming surfaces which bear against a corresponding camming surface of the insert. In axial cross section, the axis of each adjustment screw is parallel to the axis of the clamping screw and to a horizontal axis of the holder, and an axis of the insert is at an angle relative to a vertical axis of the holder.
Abstract:
A guide member is removably, but self lockingly, mounted on a cutter head. The cutter head has a dovetailed recess which receives the guide member. One side of the recess has bores which accommodate elastic elements which protrude into the recess. Friction coupling between the guide member and the elastic elements prevents axial movement of the guide member.
Abstract:
An adjustable reamer includes a securing portion, a shank, a guide members, at least one cutting insert, an adjustment device for adjusting the insert, and a clamp for clamping the insert. The clamp is releasable from the shank. A first place of contact is created between the clamp and the shank, and a second place of contact is created between the clamp and the cutting insert. An angle between the first and second places of contact in relation to the rotational axis of the reamer is at least 100.degree., preferably larger than 135.degree..
Abstract:
A chip removal tool for finishing the radial surface of a bore and having a cylindrical bit for mounting a cutting element and a deflector positioned adjacent the cutting element to deflect chips cut from the bore and urging the chips into a flow of fluid from respective cooling and lubricating sources.
