Special Purpose Machine Tools Co., Ltd. launched at CIMES2010 tool-specific machine - SK723 CNC tap thread grinder for tapping thread processing, the use of multi-line grinding wheel grinding of the workpiece, equipped with a diamond wheel automatic grinding device, select high-precision CNC closed-loop control system, easy operation and programming. Due to the use of finite element analysis software to optimize the design of the machine tool, so that the overall rigidity has been improved. The grinding wheel spindle of the machine tool is a high-precision special grinding spindle whose motor is a steplessly adjusted frequency conversion motor, which can realize the constant speed operation of the grinding wheel linear speed. The wear of grinding wheel for processing various workpieces by four CNC axes Compensation, the feed axis by the servo motor driven high precision screw pair to achieve, the machine is equipped with a fully enclosed cover and vacuum device, Machinable straight groove, spiral groove tap, squeeze tap and so on. For batch production of taps, dressing is done directly with a dressing wheel with a shaped diamond wheel, greatly reducing trimming time. Selection of Taiwan Po-yuan CNC system, easy to operate. Japan's Yaskawa servo motor and its drive configuration, such as work and the grinding head with high-resolution grating to achieve closed-loop control, grinding wheel in the processing of the wear and tear generated during the auto-compensation process to improve product processing accuracy and efficiency . The availability of the device will effectively solve the current domestic thread thread grinder low degree of automation, the use of steel wheel rolling grinding wheel manual trimming, poor product consistency, low productivity and other processing problems.
