Product Description
The VMC855 CNC vertical machining center (VMC) is equipped with a spindle axis set perpendicular to the worktable, making it easy to handle precision 2D sheet metal parts and complex 3D housing-shaped parts, as well as intricate metal molds.
The VMC855 vertical CNC machining center works with a variety of capabilities, including milling, boring, drilling, tapping, and threading.
The VMC855 CNC vertical machining center requires at least three axes with two-axis linkage to function properly, and typically works with three axes with three-axis linkage, while some high-end models require a fourth or fifth axis for 3D machining.
The VMC855 vertical CNC machining center comes with X, Y, and Z axes as standard. 4th-axis and 5th-axis are optional for multi-angle and multi-directional machining. The VMC855 utilizes a CNC controller for automated metal fabrication, featuring a compact structure, high speed and high precision, making it ideal for manufacturing a wide range of metal parts and molds. The VMC855 is small yet full-featured, offering a perfect balance of speed and power to significantly boost your productivity.

| Capabilities | The tool or workpiece can move in any direction and at any angle, machining any surface of a 3D object, such as curved or oblique surfaces in one setup, making it ideal for complex impellers, molds, dies, engines, and artificial bones. | |
Applications
The VMC855 vertical machining center is primarily designed for small and medium-sized businesses to create precision planes, cavities, contours, and holes in communications, mold making, automobiles, aerospace, electronics, medical devices, watches, and dental industries.
Projects
Pros
• Small, fast, and powerful.
• The workpiece clamping and positioning are convenient with vertical machining centers.
• The cooling conditions are easily established, allowing cutting fluid to reach the tool and machined surface directly.
• The tool movement trajectory is easy to observe, making program debugging, inspection, and measurement convenient. Problems can be detected promptly, allowing for downtime for troubleshooting or modification.
• Compared to comparable horizontal machining centers, vertical machining centers feature a simpler structure, smaller footprint, and lower cost.
• The three coordinate axes are aligned with the Cartesian coordinate system, providing a clear and intuitive view consistent with the drawing, facilitating chip removal and falloff, and preventing scratches on the machined surface.
• The repeatability accuracy reaches 0.005 mm.
• The testing standards are twice as high as industry standards.
Cons
The VMC855 vertical CNC milling machine is limited by the column height and tool changer, which restricts the height of the workpiece. It also suffers from a smaller worktable, making it incapable of handling larger metal parts and molds. When machining cavities or concave surfaces, chip removal is difficult, potentially damaging the tool and the machined surface, hindering the machining process. This limits its ability to machine only a limited range of box-shaped workpieces.
