WHAT IS MEANT BY VMC MACHINE?
A VMC is a type of CNC Machine, typically enclosed and most often used for cutting metal. As opposed to the machining with a horizontal machining center (HMC), CNC machines with the vertical machining centers (VMC) have vertically oriented spindles. Machining is a broad term encompassing the manufacturing processes that use machine tools to remove layers of material from a workpiece to produce the desired part or product. VMC workpieces are usually mounted on top of their table and perform standard 2.5 or 3 axis machining operations. VMC are useful for creating the parts, die or molds with accuracy, precision, repeat-ability and surface finishes.
The term ‘machining center’ almost always describes the CNC (Computer Numerical Control) milling and drilling machines that have an automatic tool changer and a table that clamps the work-piece in one place. CNC machining is a process that is used in the manufacturing sector, it involves the use of computers to control machine tools.
Vertical Machining Center(VMC) with the 4th Axis
A typical CNC machine is a 3 axis system, meaning that the tool will move left to right, front to back and up and down. (XYZ axis). Axis stands for the number of motors that can be individually driven for positional control of the tool. It means you are limited to using flat stocks such as wood, plastic sheets, metal sheets or blocks, etc.The x-axis is usually from left to right, the y-axis is front to back, and the z-axis is up and down. On a standard 3-axis VMC, the cutter stays in the vertical direction. In VMC’s, we can add 4th axis as well to increase the benefits of the VMC.
Use BODSEE system equipment and add the 4th axis, to achieve better processing efficiency.
If the 4th-axis is added in VMC, then the cutter can rotate around the x-axis which allows the VMC machine to drill holes in the front and back of the product. Hence, VMC that have an additional rotary axis are 4 axes machines. There is a fifth axis as well which adds complexity to the VMC.
