Hardinge's Bridgeport V1320 vertical milling center is an addition to the Bridgeport V-series vertical milling center line. The center is equipped with dual Y-axis ballscrews to improve surface quality, reduce vibration, provide acceleration, improve roundness accuracy and increase tool life.
ادامه مطلبA vibration mill is a size reduction equipment that applies the process of continuous impaction in carrying out its size reduction function. The grinding container is made up of a tube that is held in a frame that is supported by means of springs which is filled to approximately 80% total volume with porcelain or stainless steel balls.
ادامه مطلبA vibration in the tool leads to a wave in the workpiece, constant vibration creates a steady series of these waves. Now imagine what happens if you make a second pass over a surface that is already wavy from chatter–the forces on your cutter …
