The company focuses on the localization of imported precision grinding equipment, integrating international advanced technology with domestic market demands to develop a full range of grinding equipment covering surface, internal, external, forming, and irregular shape grinding, fully meeting the diverse processing needs of different industries.

Product Parameters

Product Features

1.High Precision and Consistency
The CNC Punching Bar Grinding Machine employs a high-precision CNC system to precisely control the position of the grinding wheel and workpiece. Repeatability reaches 0.001mm, achieving micron-level precision machining. This ensures high consistency in punch outer diameter, angle, and curvature dimensions, effectively avoiding dimensional errors caused by manual operation. Simultaneously, it enables micron-level grinding, obtaining a high-gloss surface, reducing punch-die engagement and roughness issues, and extending die life, aligning with the high-precision machining trend in modern manufacturing.
2.One-Stop Grinding of Complex Shapes
Through multi-axis linkage and a forming grinding wheel, the machine can complete the precision grinding of complex shapes, multiple tapers, and multiple curvatures (such as plum blossom shapes, twelve-sided, and twenty-four-sided shapes) of punches in a single operation, eliminating the need for multiple clamping operations, significantly improving processing efficiency and reducing processing errors.
The CNC Punching Bar Grinding Machine is equipped with a dedicated forming grinding CNC system (such as SMART i Control), supporting graphical programming or parameter input. It can automatically complete all processes, including rough grinding, fine grinding, and chamfering, within a single machining cycle, simplifying the operation process and reducing the skill requirements for operators.

Product Applications

1. Mold Parts Machining
As a core application of the CNC Punching Bar Grinding Machine, it is mainly used for grinding various cold heading and cold extrusion punches. It is particularly adept at handling complex and irregularly shaped punches, and can complete precision forming grinding of complex contours with multiple arcs, angles, and steps in a single clamping operation. This replaces traditional manual grinding, improving processing efficiency and product quality. It is suitable for grinding multi-angle punches such as twelve-corner and twenty-four-corner punches, as well as irregularly shaped punches such as the pentagonal shape.

2. Fastener Industry
Punches are commonly used in the final stage of the forming process for fasteners such as bolts and nuts, and their precision directly affects product quality. Ningbo CCMS CNC punch bar grinding machines ensure consistent punch dimensions and height, meeting the stringent precision and wear resistance requirements of mass production, providing reliable equipment support for the fastener industry.

3. Parts Machining
With its high rigidity and precision CNC system, the CNC punching bar grinding machine is also suitable for grinding other types of punch parts, especially those with large length-to-diameter ratios, complex shapes, and high precision requirements. It enables mass production and is widely used in cutting tools, ceramics, hardware molds, screw and nut molds, power tools, and heavy electronics industries.
