Dalian CNC parts processing

Dalian CNC parts processing is not only used for large batch parts processing, but also for small batch parts and high-precision parts processing. NC machining has good flexibility and high degree of automation. It is especially suitable for machining curved and curved parts with complex contour shapes, complex boxes with a large number of holes and grooves, and prismatic parts. In the case of multiple varieties and small batch production, CNC machining can achieve higher economic benefits. How can CNC machine parts? Now let's introduce the Dalian Parts Processing Group.

The processing of CNC machining process problems is basically the same as that of ordinary machining, but it has its own characteristics. Therefore, when designing the NC processing technology of parts, we should not only follow the principle of good flexibility and high degree of automation in NC processing, but also be particularly suitable for processing curve and curved surface parts with complex contour shapes, as well as complex boxes and prismatic parts with a large number of holes and grooves. In the case of multiple varieties and small batch production, using NC machine tools to process can obtain higher economic benefits.

The determination of tool setting point and tool change point of CNC machining center. The tool setting point is the starting point of tool movement relative to the workpiece during CNC machining. Since the program is executed from this point, the tool setting point is also called the program starting point or tool starting point. When programming, the selection of tool setting point position shall be considered first.

When the machining accuracy is not required, some surfaces on the workpiece or fixture can be directly used as the tool face; When the machining accuracy is required to be high, the tool setting point should be selected on the design basis or process basis of the part as far as possible. For example, for the part located by the hole, it is appropriate to take the axis of the hole as the tool setting point.

The tool setting point must have a certain coordinate relationship with the workpiece positioning datum, so as to determine the relationship between the machine tool coordinate system and the workpiece coordinate system. The selection of tool setting point shall facilitate the calculation of coordinate value and facilitate tool setting.

During tool setting, make the tool setting point coincide with the tool point. The so-called cutter point refers to the intersection point of the cutter axis and the cutter bottom surface for the flat end mill; For ball end milling cutter, it refers to the ball center of the ball end part; Turning tool refers to tool tip; For drill bit, it refers to drill point; For wire electrode cutting machine tools, it refers to the focus between the axis of wire electrode and the part surface.

CNC machining has solved the problem of complex, precise, small batch and multi variety parts processing well. It is a flexible and efficient automatic machine tool, represents the development direction of modern machine tool control technology, and is a typical electromechanical integration product.
