What programming methods are commonly used in CNC horizontal machining centers?

CNC horizontal machining center is an important equipment in current mechanical processing enterprises. According to the installation form of the spindle, it can be divided into vertical machining center and horizontal machining center. The spindle axis of the horizontal machining center is set parallel to the workbench. It is mainly suitable for processing box-type parts and is the most commonly used type of machining center.

CNC horizontal machining center refers to a machining center with the spindle axis and the workbench set parallel to each other. It is mainly suitable for processing box-type parts. Its working principle is that after the workpiece is clamped once on the machining center, the computer can automatically select different tools, automatically change the machine tool spindle speed, and sequentially complete multi-process processing on multiple surfaces of the EDM Wire Cutting And Milling Machining 45# Steel Parts. Its advantage is that it can greatly improve production efficiency, but it occupies a large area and is costly.

The worktable of the CNC horizontal machining center uses 4 positioning cone blocks for positioning. Together with the air blowing and hydraulic pull rods on the cone block surface, the rigidity and precision of the workbench are maintained at high stability. Optional automatic exchange workbench with workbench positioning accuracy of 1 degree or 0.001 degree (optional).

There are usually two programming methods:

  • ① Simple contour – a contour composed of straight lines and arcs, programmed directly with the G code of the CNC system.
  • ② Complex contours – three-dimensional surface contours. Use automatic programming software (CAD/CAM) to draw three-dimensional graphics in the computer, set various corresponding parameters according to the surface type, and automatically generate CNC machining programs.

The above two programming methods can basically meet the requirements of CNC machining. However, it is very difficult to process the contours of functional equation curves, because early milling machine CNC systems do not have function calculation functions, and the processing program of functional equation curves cannot be compiled directly using G code, and (lower version) CAD/CAM software usually does not It has the function of directly inputting graphics from equations. Therefore, the commonly used method for cutting function equation curve contours is: according to the drawing requirements, calculate the coordinates of each point on the curve, and then use the straight line or arc command code to compile a program based on the calculated coordinate values, and manually enter the system for processing.

For CNC horizontal machining centers, defensive measures must be taken to prevent electrical shock and electrical shock caused by high voltage inside the main electrical cabinet, control panel, transformer, motor, terminal box or operation panel and its area. To prevent accidents, be careful not to touch the machine tool’s switches with wet hands to prevent electric shock.

For CNC horizontal machining centers, it is necessary to check once a quarter to prevent circuit aging or some machine tool function errors. This can prevent accidents from happening and control the occurrence of accidents from the source. At the same time, prepare a strong workbench around the machine tool and do not mess with it. Slide off its surface.

Only by correctly testing the CNC horizontal machining center, and secondly by following the operation manual during operation, can the machine tool operate better and extend the working life of the machine tool.
