Abstract
The Cutting process used in milling is one of the most common type of industrial machining methods. Similar to traditional milling spindles, the motor driven spindles are fitted with an integrated motor, thereby eliminating belts and gears for the transmission of power from the motor to the cutting tools. The innovative machine tools should be highly characterized systems in order to retain the necessary precision, efficiency and reliability. To satisfy their end user's reliability and availability requirements, both the spindle system (Tool/Tool-Holder/ Spindle) and motor tool system need to be configured for their usability and output results. However, the quality of a control device in industrial practice is greatly affected by the spindle cutting output and its reliability. The motor spindles are nothing but the rotating drive shafts which acts as axes for cutting force tools or in machining process for holding cutting instrument. Hence the spindles are one of the important factor in machining tool process and productivity, as these are used to produce parts as well as machines that produce components, which in turn have a significant impact on production levels and quality of products.
Highlights
To a large degree, industrial productivity depends upon the technology where the use of high-frequency motorized milling spindles are used a professional technology to dramatically improve efficiency and reduce productivity costs
1) Consideration may be given in overcoming the problems of improper loading on bearings and measurement of dynamic output of the motorized spindle
2) The motorized spindles propose an alternative method to the non-motorized milling spindles in terms of achieving greater speeds and effective cutting process
Summary
Industrial productivity depends upon the technology where the use of high-frequency motorized milling spindles are used a professional technology to dramatically improve efficiency and reduce productivity costs. High speed spindles are the most critical part of any kind of fast machining process today The use of these high speed spindles increases the efficiency for all sorts of machining operations, whether in the CNC process and the machining center or other process components. A model of motor spindle is fitted with an spindle shaft in term it is having integral parts with an integral motor, by removing the need for traditional transmission of power devices such as gears, pulleys and belts This kind of arrangement eliminates wear and tear and oscillations of the cutting tool, maintains a high rotational equilibrium. This allows the tool with more precise control of increase or decrease in the speed of the shaft. The high rotational speeds of the shaft with built-in engine often add significant quantity of increase in temperature and chatter formation, which requires correctly control of cooling system by desired lubrication and proper balancing
