Just What exactly is CNC Machining and how does it work?


CNC machining service

Numerical control (also computer numerical control and more commonly referred to as CNC) is the controlled automation of machining equipment (such as drills, lathes, mills) as well as 3D printers, by through computers. A metal casting services process the material (metal or plastic, wood, ceramic or composite) to conform to specifications following a coded programmed instruction and with no human operator who is directly in charge of the machining operation.

CNC machining is a manufacturing process that is controlled by computer software which controls the movements of factory tools and machinery. This technique can control a variety of intricate machines from lathes to grinders to routers and mills. With CNC machining the three-dimensional cutting task can be completed in a single set of prompts.

What is the process?

When a CNC system is activated, the desired cuts are programmed into the software and then dictated to the appropriate tools and machinery, which perform the dimensional task as specified, much like a robot.

The code generator used in CNC programming assumes that the mechanisms are flawless and that there is a possibility for mistakes. This is especially the case when a Computer Numerical Control Machining is directed to cut in multiple directions at the same time. The position of a machine in the numerical control system is determined by a sequence of inputs, referred to as the part programming.

With a numerical control machine the programs are input through punch cards. The programs for CNC machines are transmitted to computers via tiny keyboards. Computers store CNC programming in its memory. The code itself is written and edited by programmers. The Computer Numerical Control Machining systems are equipped with an incredibly high computational capacity. The most appealing aspect is that CNC systems are able to be altered in order to add new prompts to existing software.

Different types of CNC Milling Machines

Travelling Column Machining Centers

Hwacheon's Hi-Rex 4000/5000/6000 is CNC milling machine that uses a traveling column machining the center. The table and workpiece are fixed and do not move. The three linear axes motions are made by the traveling column which includes the spindle as as the cutting tool. These machines are designed for a extremely long, but slimmer (Y-axis direction) components or to permit multiple clamping applications of the workpiece.

Multi-Spindle and Double Spindle Machining Centers with Pallet Changers

Most often, they are fitted with Pallet Changers, vertical or horizontal multi-spindle or double-spindle machining centres are top of the line CNC milling machines. These machines are specifically designed to maximize productivity and can be used to mass produce complex parts.

Pallet Changers with Double/Multi-Spindle Machine Machining Centres

Most often, they are equipped with Pallet Changers, vertical or horizontal multi-spindle machining centers are top-end CNC milling machines. These machines are specifically designed for high productivity and are used to mass produce complex parts.

Multi-Axis CNC Machining Centres

Most metal casting services are available in the 3-axis to 5-axis range to accommodate complex shapes, mold & die or other components that must be placed in different angles. Multiple axes allow for simultaneous machining up to five faces.
