Chip Breaking And Burr Control In Gearbox Machining

Ningbo Xinhong Hydraulic Co.,Limited | Updated: Aug 26, 2017

                  In general, there are chip control problems in the application of semi-precision machining, finishing and variable cutting depth, and most of the turning processes in the automotive transmission industry need to be well cut. As Henry Ford and William C. Durant era began, this problem has plagued all carmakers. Although the automotive industry and the cutting tool industry have very advanced technology, the processing of these ductile materials, but still make operators, engineers and production managers deeply headache. From the experience of the automobile industry and the expected peak production level, the factory needs to solve this problem in any case, in order to adapt to the trend of the times, to meet production needs and maintain profitability.Gearbox

                  In solving chip control problems, physical characteristics and economic costs are the first considerations. The methods we have been using for efficient machining, including the use of the tool with the front corner and the maximum radius of the tip, are not ideal for practical use. Because while these schemes can make the chips thinner, prolonging tool life and increasing productivity, it also increases the difficulty of cutting chips. In addition, many parts have surface roughness requirements, only the use of large tip radius, to achieve qualified surface quality.Gearbox

                  The slender chips produced by turning ductile steels can seriously damage normal processing and production. If the chip is not well cut, the chip will wrap around the tool and cause downtime. If there is always downtime, and the need to manually clean out the chips, it will also make the operator feel very annoyed. This is not only a waste of time, but also high chip temperature, edge and extremely sharp, very easy to hurt people. In addition, the chip can move along the workpiece, scratching the workpiece, resulting in scrap or rework parts. If the chip is too long wrapped between the cutting edge and the parts, there will be more problems, because if the cutter to the chip to "cut", will lead to a broken knife accident. In automated operations, chip control also poses problems for material handling robots or on-line measurements, because chips interfere with the performance of the robot and give incorrect meter readings.
