Under CNC Machining, machine tools function through numerical control. A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) that essentially controls all features like feed rate, coordination, location and speeds. With CNC machining, the computer can control exact positioning and velocity. CNC machining is used in manufacturing both metal and plastic parts.



First a CAD drawing is created (either 2D or 3D), and then a code is created that the CNC machine will understand. The program is loaded and finally an operator runs a test of the program to ensure there are no problems. This trial run is referred to as "cutting air" and it is an important step because any mistake with speed and tool position could result in a scraped part or a damaged machine.



There are many advantages to using CNC Machining. The process is more precise than manual machining, and can be repeated in exactly the same manner over and over again. Because of the precision possible with CNC Machining, this process can produce complex shapes that would be almost impossible to achieve with manual machining. CNC Machining is used in the production of many complex three-dimensional shapes. It is because of these qualities that CNC Machining is used in jobs that need a high level of precision or very repetitive tasks.

The drilling machine or drill press is one of the most common and useful machine employed in industry for producing forming and finishing holes in a workpiece. The unit essentially consists of:

1. A spindle which turns the tool (called drill) which can be advanced in the workpiece either automatically or by hand.

2. A work table which holds the workpiece rigidly in position.


Working principle:


The rotating edge of the drill exerts a large force on the workpiece and the hole is generated. The removal of metal in a drilling operation is by shearing and extrusion.

Plate bending machine is a machine capable of bending thin plates, its structure mainly comprises a bracket, table and the clamping plate. The worktable is arranged on the supporting table, which comprises a base and a platen. The base is connected with the clamping plate through a hinge, and the base is composed of a seat shell, a coil and a cover plate. The coil is placed in the hollow of the seat shell, and the top of the hollow is covered with a cover plate. After the power is energized, a gravitational force is plurality of workpiece requirements, and the workpieces with slide walls can be processed because the electromagnetic force is clamped. In the word, the operation is very convenient.
