BEVELLER FOR H-BEAM BEVELING

The present invention relates to a beveller for H-beam beveling to bevel a welding surface of an H-beam to be inclined when the H-beam is welded. An existing beveller is capable of beveling a welding base material such as a pipe and a plate for the improvement of welding but is not applicable to the beveling of an H-beam which is frequently used in construction sites. To resolve this problem, the beveller for H-beam beveling lowers a magnetic square to temporarily fixate an H-beam to exclusively bevel the edge of a lower plate of the H-beam by making a beveller main body connected to the front side of the H-beam support frame through an LM guide linearly move, wherein the lower plate of the H-beam is inserted into a space between a pair of magnetic squares installed on both sides on the top of an H-beam support frame to move up and down and the H-beam support frame.

The tool is rotated and the concaved surface of the cutting edge of the tool is moved to approach an arcuated R face of the object to cut the edge portion formed by a spattering surface and a side surface of the spattering target, wherein the radius of curvature Ra of the arcuated surface in the cross section along the axis of the tool is so set as larger than the radius of curvature Rb of the R face of the object, and the two ends of the concaved surface of the cutting edge of the tool are so set to depart from the spattering target while the edge portion of the spattering target is being cut.

METHOD FOR DEBURRING END FACE OF FORMED GROOVE, AND FORMED ROTARY CUTTING TOOL FOR CHAMFERING

Using a tree-shaped groove chamfering tool (70) formed by changing the radial shape of a Christmas tree form cutter (30) used for cutting work of a tree-shaped groove (52) to correspond to a predetermined chamfer angle (θ), the tree-shaped groove chamfering tool (70) is moved relatively to an end face (90) of the tree-shaped groove (52) in a direction perpendicular to an axis (C) thereof on an axis movement trajectory (94) which forms the chamfer angle (θ) with the axis movement trajectory (92) of the Christmas tree form cutter (30) in the cutting work of the tree-shaped groove (52) while being rotationally driven around the axis (C), thereby performing chamfering work for deburring the end face (90). As a result, deburring work can be mechanized by the same machine as a machine for cutting work of a formed groove, and skills of an operator are not required because of a uniform and simple operation, thereby enabling shorter operation time and unmanned operation.

STAR-SHAPED CUTTING INSERT FOR A FRONT AND BACK CHAMFERING ROTARY MILLING CUTTER

Electronic devices with reflective chamfer surfaces

The embodiments described herein relate to methods, systems, and structures for cutting a part to form a highly reflective and smooth surface thereon. In some embodiments, the part includes substantially horizontal and vertical surfaces with edges and corners. In described embodiments, a diamond cutter is used to cut a surface of the part during a milling operation where the diamond cutter contacts the part a number of times with each rotation of the spindle of a milling machine. The diamond cutter has a cutting edge and a land. The cutting edge cuts the surface of the part and the land burnishes the surface of the part to form a highly reflective and smooth surface. Thus, the diamond cutter cuts and burnishes portions of the part, thereby eliminating a subsequent polishing step.

Chamfering machine for pipe welding groove

The present invention relates to a chamfering machine for improving pipe welding and, specifically, to a new technological concept capable of smoothly chamfering pipes of more various pipes by expanding a minimum chamfering range of a pipe which can be chamfered while having only an internal driving roller located inside the pipe during chamfering of the pipe. Since an existing chamfering machine can chamfer only a pipe of an interference-less diameter at least in a state wherein an internal driven roller and a driven roller position adjustor are located inside the pipe, a problem can arise for which another small chamfering machine needs to be prepared to chamfer a small-diameter pipe (no greater than 250 mm) because its minimum chamfering range is limited. In order to solve the problem, the present invention embodies a special structure, wherein when a chamfering machine is mounted on a pipe, only an internal driving roller is located inside the pipe, and a driving roller position adjustor for adjusting vertical positions of the internal driving roller is located outside the pipe, thereby expanding a minimum chamfering range of a pipe.

Chamfering tool

At a truncated cone-shaped cutting section (3) of a chamfering tool (1), a first edge part (31) inclined to discharge chips to the shank part (2) side and a second edge part (32) inclined to discharge chips in the direction opposite the shank part (2) side are formed at an interval in the circumferential direction. The chamfering tool (1) is rotated to cause the first edge part (31) and the second edge part (32) to be alternately in contact with an edge of a workpiece to perform chamfering. This suppressed production of secondary burrs at the edge.

Back chamfering tool for hole working

본 발명은 누구라도 쉽게 휴대용 전동기구에 장착하여 구멍의 배면을 안전하게 모따기 작업을 수행할 수 있고, 대량 생산에 적합하여 생산성 향상에 기여할 수 있으며, 챔퍼링커터의 커터날이 샤프트의 누름작동에 의해 외주방향으로 돌출되므로 전동기구에 끼워져 회전되더라도 작업자에게 상해를 가할 위험이 없고, 조정하우징과 스톱퍼링을 통해 구멍의 깊이에 따라 챔퍼링커터의 삽입깊이를 조절할 수 있으므로 다양한 가공물의 두께에도 적용가능하며, 가공물의 두께에 맞게 조정하우징의 상하 위치이동시 가이드블럭의 홀삽입가이드 외주면에 눈금자가 형성되어 쉽게 구멍의 깊이에 맞는 백챔퍼링 작업을 수행할 수 있는 구멍 가공용 백챔퍼링 공구에 관한 것이다.
