Horizontal machining center, also known as CNC lathe, is a horizontal machining center with large international coverage and wide coverage. Horizontal machining center is a mechatronics product integrating mechanical, electrical, hydraulic, pneumatic, microelectronics and information technologies. As a horizontal machining center manufacturer with more than 50 years of machine tool manufacturing history, horizontal machining center products are subdivided into hard rail horizontal machining centers, line rail horizontal machining centers, inclined bed horizontal machining centers, and high precision horizontal Processing center, etc. Users who are engaged in mechanical processing industry are not unfamiliar with horizontal machining centers, but for users who are just engaged in mechanical equipment industry, facing many horizontal machining center manufacturers, many horizontal machining center models, choose one High-quality equipment is indeed a difficult thing.
Use a dial indicator to set the knife. This method is a method of sensitively using several accessories of the lever dial indicator to reach the score. The operation method is as follows: the clamping cap of the lever dial indicator is set on the main shaft, and then the dial indicator is mounted on the clamping cap. Assuming that the X axis is in the middle, move the machine table to gradually press the dial indicator to the processed appearance of the workpiece, manually rotate the spindle, and check the large value of the dial indicator (if it is not an integer, you can move the spindle to adjust the value of the dial indicator) Integer), and then return the absolute coordinate of the X axis to zero; then move the spindle to the other side of the workpiece, the same operation method, get the total value of the X axis, move the spindle to half of the total value (two ends of the workpiece) and set Coordinate System. The disadvantage of this method is that it takes a long time for the machine tool. When the processing depth of the front is not enough, the edge of the blank is easy to interfere with the dial needle of the dial indicator or the dial indicator can easily interfere with the vise jaw. In addition, when the Y axis is centered, check The dial indicator value is inconvenient; the advantage is that the tool setting accuracy is higher.
The rotational motion of the grinding wheel of the horizontal machining center does not require speed regulation under ordinary conditions. A three-phase asynchronous motor can be dragged and only requires one-way rotation. When the capacity is large, Y-triangular pressure reduction can be used to start. In order to ensure its processing accuracy, the horizontal machining center can make it run bumpy, and ensure that the inertia of the reciprocating movement of the worktable is small and has no impact. Therefore, the hydraulic drive is used to complete the worktable reciprocation Movement and lateral feed of the wheel box. The rotating speed of the grinding wheel of the horizontal machining center is very high, and the grinding wheel is relatively hard and brittle. In the process of application, it can not withstand heavy impacts. Such occasional improper operation, its crushing of the grinding wheel will directly form its very serious result. Therefore, the safety technical task of grinding processing is particularly important, and it is necessary to adopt a reliable safety protection device, and the operation must be physically concentrated to ensure foolproof.
