The invention relates to an apparatus for cutting an oval hole in the wall of a pipe. The pipe secured to a baseplate (1) of the apparatus is cut for an oval hole by means of a tool (20) having its cutter head (24) rotated about its axis while it is driven along a circular path in relation to a carriage (2) of the apparatus. The carriage (2) is mounted on the baseplate (1) by way of linear runners (3). Adapted for rotation along with a drive pulley (4) of the tool (20) is a cogged wheel (10), which through the transmission of a cam lever (11) is adapted to drive a shaft (12) having its rotational motion transmitted on the one hand to drive a gear (22) and on the other hand to work the carriage (2) back and forth in relation to the baseplate (1), a round-trip displacement (2xa) being equal to a difference between the major axis and the minor axis of a desired ellipse.

An apparatus (100) for machining a tubular or round-bar type piece, wherein the apparatus comprises a frame element (102), a machining unit (104), as well as a threaded shaft (110), which is fitted to the frame element in a rotatable and axially immobile fashion and has a first section 110a) provided with a right-handed thread and a second section (110b) with a left-handed thread. The first section is provided with at least one first support element (106a) and the second section is provided with at least one second support element (106b), the mutual distance between the support elements being adjustable in response to rotating the threaded shaft, such that the support elements, for example wheels, are adapted to touch a workpiece and to support and guide the apparatus (100) in the process of machining the piece. At least one of the support elements, such as wheels (106a, 106b), is adapted to be capable of rotating relative to its axis in response to moving the apparatus along the surface of a workpiece.

A method for removing a weld crown from a weld joint between first and second work pieces includes steps of positioning a rotary milling tool proximate to the joint and at an offset angle to set a cutting arc relative to the joint. The milling tool is positioned so the cutting arc intersects the weld crown, weld toes, and parent metal on each side of the weld joint. As the milling tool traverses the joint to cut away the weld crown, the milling tool may tilt from side to side to compensate for misalignment between the work pieces along the weld joint. An apparatus for weld crown removal holds a milling tool at an offset angle, and provides a tracking mechanism to permit the milling tool to track misalignment between the work pieces, maintaining the cutting arc in intersection with the weld toes and parent metal along the weld joint.
摘要:
The invention relates to a method and an apparatus for making an elongated hole in a pipe (P) by means of a rotating conical drill (1). The elongation of a hole is accomplished such that, during the course of drilling, the conical drill is manoeuvered simultaneously in the longitudinal and tranverse direction of the pipe, the transverse movement being effected away from or towards the centre axis. This combined movement is accomplished by tilting the conical drill while simultaneously lifting the drill out of the pipe. Alternatively, the drilling can be commenced from the end of a hole, progressing towards the centre of a hole while increasing the drilling depth.

The invention concerns a radius-milling fixture for machining workpieces by means of a hand-held router. The fixture has a rectangular support (1), made preferably of plexiglas, which has a support surface designed to accommodate the hand-held router. The support (1) has a slot in which a fastening device (31, 32) can slide. The fastening device (31, 32) is fitted with a bolt which can be inserted in a bore in the workpiece (40) to be machined. Tightening the fastening device locks the bolt in place relative to the support (1).

관재나 봉재의 면깍기 작업시 최적의 절삭조건에 해당하는 위치에 피가공물이 고정될 수 있도록 하여 원활한 절삭작업은 물론, 피가공물의 원시적인 결함에 의한 가공불량까지도 최대한 방지할 수 있는 면취기가 개시된다. 본 발명에 따른 면취기는 상부가이드의 하부면상에 피가공물의 외주면 일부가 삽입되는 절삭위치홈이 형성되되, 절삭위치홈의 중앙부가 면취커터의 절삭단부와 일치하도록 형성된다. 또한, 본 발명에 따른 가공방법은 원형재의 어느 중심선 방향에 대해 면취커터가 수직으로 진입하며, 절삭팁의 절삭단부가 중심선과 일치되는 지점까지 절삭하면서 진입한 후, 관재를 자전시키거나 관재를 중심으로 면취커터를 공전시켜 원형재의 표면을 면깍기 할 수 있게 된다.
摘要:
The aim of the invention is to provide a connection means for connecting a first component to a second component, especially for connecting pieces of furniture or parts of machines, said means comprising a first connection element arranged on the first component when the components are connected, and a second connection element arranged on the second component when the components are connected, and enabling a secure connection of the two components consisting of a plurality of materials, without causing any risk of damage to the two components during the assembly thereof. To this end, at least one of the connection elements comprises at least one holding projection that is not self-cutting and has a curved supporting surface in the form of the arc of a circle in a longitudinal section. Said holding projection can be inserted into a groove created on one of the components and having a curved undercut surface in the form of the arc of a circle in a longitudinal section.

A cutting tool and track system includes a multi-segment track assembly (14) configured to be removably attached to a surface of a workpiece (50), a carriage assembly (18) configured to ride along the track assembly (14), a carriage drive mechanism (16) arranged to drive the carriage assembly along the track assembly, a cutting tool assembly (12) connected to the carriage assembly (18), and a tool driving system (46) connected to the cutting tool assembly (12). The cutting tool assembly rotatably supports an end mill type cutting tool (24) that may be driven in a radial cutting plane about the axis of a tubular workpiece or along a workpiece surface. A method is provided for cutting a workpiece wherein a cutting tool assembly rotatably supports an end mill mounted for travel along a predetermined transport path in a cutting plane about a central axis of the workpiece wherein the end mill is first fed through the wall thickness of the workpiece and the cutting tool assembly is moved along the transport path in the cutting plane to cut the workpiece.
