The machine tools of Dongguan numerical control processing plant are developed from the early Egyptians' pedal powered car and John Wilkinson's boring machine. They provide rigid support for the workpiece and tool, and can accurately control their relative position and relative speed. Basically, metal cutting refers to a sharpened wedge-shaped tool to remove a narrow strip of metal from a tough workpiece surface. Chips are discarded products. Compared with other workpieces, chips are shorter, but the thickness of uncut part is increased. The geometry of the workpiece surface in Dongguan CNC machining plant depends on the shape of the tool and the path of the tool during the machining operation.
Most of the machining processes in Dongguan CNC plant produce parts with different geometric shapes. If a rough workpiece rotates on the central axis and the cutter cuts into the workpiece surface parallel to the rotation center, a rotating surface is produced. This operation is called turning. If a hollow pipe is machined on the inner surface in the same way, this operation is called boring. When the diameter is changed evenly, a conical outer surface is produced, which is called taper turning. If the tool contact point moves in the way of changing the radius, a workpiece with an outer profile like a ball will be produced; Or if the workpiece is short enough and the support is very rigid, an outer surface of the forming tool normally fed relative to the rotation axis can be formed, and a short conical or cylindrical surface can also be formed.
Flat surfaces are often required and can be produced by turning the tool contact point radially relative to the axis of rotation. It is easier to fix the cutter and place the workpiece under the cutter for larger workpiece in Dongguan CNC machining plant. The tool can be fed back and forth. The forming surface can be produced by forming tool.
Multi edge tool can also be used, using double edge groove drilling depth is 5-10 times the diameter of the hole. The relative motion between the cutting edge and the workpiece is an important factor whether the bit rotates or the workpiece rotates in Dongguan CNC plant. In milling, a rotating tool with many cutting edges contacts with the workpiece, and the workpiece moves slowly relative to the tool. Flat or formed surfaces may occur depending on the tool geometry and feed mode. It can produce transverse or longitudinal axis rotation and feed in any three coordinate directions
