The XK7140 bed CNC milling machine is an efficient and versatile milling machine. This machine is equipped with a computer digital control system, which can complete spatial curve and surface machining. One clamping of the workpiece can complete various processes such as milling, boring, drilling, and reaming. The xk7140 milling machine adopts a floor standing structure; Good rigidity; The spindle system uses a variable frequency speed regulation three-phase asynchronous motor, which achieves a continuously variable speed of 40-1500 revolutions per minute for the spindle through a frequency converter, and has strong adaptability to different material processing. Suitable for small feed cutting.
The design of this machine tool extensively adopts the latest developments in mechanical structures and has the following outstanding features:
1) The X, Y, and Z directions are all supported by hard rails, and the guide rail surface is treated with plastic coating for wear resistance, enhancing its service life.
2) The layout design of column fixation, lifting platform, and cross slide table movement greatly improves the contact stiffness of the machine tool.
3) Ball screws are used for the X, Y, and Z directions to ensure feed accuracy during long-term operation. And there are stop rings at the top of the three-way screw. It can ensure that the screw nut will not be damaged after the three directions of travel are in place.
4) The machine tool is easy to operate, and the CNC panel is equipped with manual and CNC conversion, as well as operation buttons such as forward, reverse, stop, tapping, and automatic drilling indicator lights; The spindle speed can be selected using a handle, and there are four options for feed rate; It is very convenient to process individual parts.
5) The machine tool has a complete lubrication system, and important transmission parts and bearings are automatically lubricated by a motorized oil pump.
2.3.2 Introduction to Major Parts
1. Base: The base is an integral structure, and its main purpose is to support the weight of the workbench and slider. In addition, cutting fluid is also installed here.
2. Column: Its main purpose is to support the up and down sliding of the spindle box.
3. Spindle box: The spindle box is the heart of the machine tool, and its main purpose is to complete the machining actions of speed conversion, automatic feed, drilling, tapping, and milling in this mechanism.
4. Sliding block: Its main purpose is to complete the conversion between X and Y directions.
5. Workbench: Its main purpose is to clamp workpieces and complete the entire machining process here.
