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 a horizontal machining center is set parallel to the worktable and is mainly suitable for machining box type parts. It is a type of machining center that is widely used.

CNC horizontal machining center refers to a machining center with the spindle axis parallel to the worktable, mainly suitable for machining box type parts. His working principle is that after the workpiece is clamped once on the machining center, the computer can automatically select different cutting tools, change the spindle speed of the machine tool, and complete the machining of multiple surfaces and processes of the workpiece in sequence. The advantage of CNC machining centers is that they can greatly improve production efficiency, but they occupy a large area and have high costs.

This product's workbench uses four positioning cone blocks for positioning, combined with blowing air and hydraulic pull rods on the cone block surface, to maintain high stability in rigidity and accuracy of the workbench. Optional automatic exchange workbench with a positioning accuracy of 1 degree or 0.001 degree.

There are usually two programming methods for CNC machining center products:

1. Simple contour - a contour composed of straight lines and arcs, directly programmed using the G code of the CNC system.

2. Complex contour - a three-dimensional surface contour, which is drawn using automatic programming software (CAD/CAM) in a computer to create a three-dimensional shape. Various corresponding parameters are set according to the surface type, and a CNC machining program is automatically generated.

The above two programming methods can basically meet the requirements of CNC machining. However, it is difficult to process the contour of function equation curves because early milling machine numerical control systems did not have function operation functions, and it was not possible to directly program the machining of function equation curves using G-code. (Lower version) CAD/CAM software usually did not have the function of directly inputting equations into graphics. So the commonly used method for cutting function equation curve contour is to calculate the coordinates of each point on the curve according to the drawing requirements, and then use line or arc instruction codes to program and manually input them into the system for processing based on the calculated coordinate values.
