Description

Jig for eliminating cutting chips The present invention relates to a jig for removing cutting chips, and more specifically, to provide a jig for removing cutting chips that are generated and stuck in a cutting tool when cutting a workpiece using a cutting tool such as a drill or a cutting bit on a CNC lathe. Generally, machines that process metallic or non-metallic materials using appropriate tools via cutting or non-cutting methods are called machine tools. Machine tools include commonly known general-purpose machine tools such as lathes, milling machines, grinders, drilling machines, tapping machines, and boring machines, as well as NC (Numerical Control) machine tools, CNC (Computer Numerical Control) machine tools, turning centers, and machining centers. When a workpiece is machined using a tool in a machine tool, especially when drilling operations are performed using a drill, foreign matter called cutting chips is generated. These cutting chips accumulate on the machined part of the workpiece, on the grooves and circumference of the drill, or in the grooves of a recessed cutting bit. If cutting chips generated during the machining of a workpiece continue to accumulate, it reduces the precision of the machining and, in severe cases, causes tool breakage and damage to the workpiece. Therefore, general machine tools supply coolant (cutting fluid) to the area where cutting chips accumulate to prevent the accumulation of cutting chips. The cutting chips removed by the coolant are collected in a box of a predetermined size equipped in the machine tool, allowing the operator to clean them all at once. However, while lightweight cutting chips can be easily removed by the spray pressure of the coolant using a nozzle, heavy cutting chips tend not to be easily removed even when coolant is sprayed. In particular, cutting chips that are twisted around the drill due to the drill's rotation may not be easily removed. This leads to problems such as increased costs and environmental contamination caused by the excessive use of coolant. In order to solve the problem among these issues where cutting chips continue to accumulate on the processing part of a workpiece, thereby reducing the precision of the processing and, in severe cases, causing tool breakage and damage to the workpiece, Public Patent No. 10-2021-0048104 (May 3, 2021) proposes, through Claim 1, a cutting chip removal device for a machine tool comprising: a cutting chip detection sensor installed in a cutting chip loading section where cutting chips accumulate in a machine tool to detect cutting chips; a coolant nozzle installed to spray coolant into the cutting chip loading section of the machine tool; and a controller that controls the operation of a coolant pump using the signal of the cutting chip detection sensor. Japanese Patent Publication No. JP 06-09141 (April 4, 1994) discloses a device for removing cutting chips attached to a drill tool by installing a clamp-shaped clamp on the table of a machine tool and placing a drill tool between the clamp-shaped clamps. Japanese Patent Publication No. JP 06-114617 (April 26, 1994) discloses a device for removing cutting chips attached to a drill tool by installing a pair of plates on the upper surface of a main body containing an air cylinder and placing a drill tool between the plates. Japanese Utility Model Publication No. Hei 1-21683 (June 28, 1989) discloses a configuration in which a cutting chip removal plate having V-shaped cuts is used to remove cutting chips attached to a drill tool by placing a drill tool between the V-shaped cuts. Although the prior art described above can easily remove cutting chips that may occur on the outer surface of a cutting mechanism, particularly a drill, small metal debris in addition to cutting chips may adhere to the outer surface of the drill. Since this debris is not easily removed by the devices of the prior art, there was a possibility that it could adversely affect precision in the processing of other metals in the future.
