CNC8240 Cut Point Tracking CNC Crankshaft Grinder

参数配置

发布时间： 2013 - 11 - 29

The grinder is a national 863 support project in 2008.The machine tool adopts the grinding method which is based on the grinding point cut. It does not need the auxiliary mechanism such as eccentric fixture, indexing device and so on. Using imported spindle system, the maximum speed of CBN grinding wheel can reach 120m/s. We have developed the interpolation software of the crankshaft cutting point tracking and grinding, and the grinding point of the grinding wheel is always following the rotation of the crankshaft to realize the high precision grinding of the crankshaft. The feed of the grinding wheel is driven by straight line, which has the characteristics of high acceleration response. At the same time, the rigidity and the sensitivity of the grinding wheel are improved by using the sel...

CNC8312A CNC camshaft grinding machine

发布时间： 2017 - 02 - 28

And the grinding liquid by paper filtering and magnetic separation of water mist and dust; the dust suction device, the operator only need materials up and down, a person can see the number of machine tools, so the production efficiency is high, suitable for all kinds of automobile engine, motorcycle engine and diesel engine production manufacturers.Main structure and technical characteristicsThe bearing structure of high speed motorized spindle is in our own intellectual property and has been successfully used for many years in the high-speed grinding machine "gap cavity hole type oil return throttling liquid hydrostatic bearing on the prototype formed by an improved design. With a good bearing stiffness (up to 340N/ m), high rotary accuracy (radial, axial runout is less than 0.002mm...

MKG1320超高速数控外圆磨床

发布时间： 2017 - 02 - 28

该设备是2009年国家重大专项支持项目。可以解决工程陶瓷、微晶玻璃、硬质合金、人造宝石晶体等超硬材料、钛合金、不锈钢、镍基铁氧体材料等耐热合金材料以及复合涂层材料等难加工材料轴类零件的精密加工问题，适用于航天航空、国防军工等行业中的特定材料零件的加工。MKG1320超高速数控外圆磨床可配备自主研制的超高速电主轴砂轮架及进口电主轴砂轮架，线速度可高达150m/s。借助AE在线监控系统可实时监测砂轮的磨削及修正工况，为快速正确确定磨削工艺提供可靠依据。自动跟踪定心中心架的采用可大幅提高细长工件加工的尺寸及形状精度，另配合全功能在线量仪可大大提高生产效率，有效降低生产成本。超高速电主轴超高速电主轴采用油冷电机后置动静压电主轴系统。主要由液体动静压轴承系统、主轴动平衡系统、电机冷却系统及高速CBN砂轮组成。通过液体动静压轴承的优化设计，可保证主轴的平稳启动及高速运转时的主轴刚度。主轴由后置电机直接驱动，通过精确控制转子与定子的同轴度及间隙可有效消除驱动单元给主轴系统带来的扰动。主轴系统由砂轮架主轴、CBN砂轮及在线动平衡仪组成。砂轮主轴加工后做精密动平衡，为保证砂轮装卸后主轴系统的动平衡，本机采用进口SBS在线动平衡仪对主轴系统进行精密动平衡控制。另外，设计过程中采用有限元法对砂轮架系统及整机作振动性能分析，并通过实验确保砂轮架在工作速度范围内整机不发生谐振。一系列关键问题的解决可保证砂轮架在高速状态下稳定工作。主轴动平衡本公司MKG1320超高速外圆磨床采用CBN砂轮，当CBN砂轮高速旋转时，其修整状态，磨削状态都无法像普通砂轮磨削和修整时用人工观察并进行控制。在磨削和修整期间，砂轮和工件都会产生一定频谱的噪声，其主要分布在超声波的范围内，与其他外界产生的噪音（...
