CNC machining principle: when the nc system is activated, the required processing size be programmed into the software, and assigned to the corresponding tools and machines, they are the size of the specified tasks like a non standard fasteners robot. In the numerical control programming, in the digital system The code generator usually assumes that the mechanism is perfect. Despite the possibility of error, but when the numerical control machine were instructed to multiple direction cutting at the same time, that will be more likely. Cutting tools in numerical control system of placement program consists of a series called parts
Summary of the input.
The advantages of CNC CNC machining:
Number of (1) a substantial reduction in tooling, processing complicated shape parts does not need complex tooling. To change the shape and size of the parts, only need to modify parts processing procedure, suitable for the development of new products and upgrading.
(2) stable machining quality, high machining accuracy, high Steel investment casting repeat precision, satisfy the processing requirements.
(3) in the case of many varieties, small batch production, high production efficiency, can reduce the production preparation, machine tool adjustment and process the test of time, and reduce the cutting time by using the cutting quantity.
Conventional methods can be processed (4) to the complexity of surface processing, processing and some even can observe the machining parts. Stamping processing to prolong the service life of the press, to ensure the accuracy of press, the operator must press the right conduct routine maintenance work. Maintain good press can ensure the quality of stamping parts processing and reduce equipment failures, and help guarantee the safety of operating personnel to reduce safety accidents. Let's look at press daily maintenance methods:
A. before start working. Before start working, should to be prepared for socket screw plug the following. Adductor muscle pain often pick up the work place. Around the pressure on the machine and press, has nothing to do with the work items must be clean, and the workpiece and the billet is put in the proper position. Check the press area of friction and lubrication part have wear phenomenon, oil cup should be filled with lubricating oil. Detection of stamping die is accurate and reliable installation, edge crack, dent and gap must be after the separation of the clutch, material can start motor. Test brakes, clutch, flexible manipulator whether the action of various components, accurate, reliable, and do a few empty schedule try to rush, began to work again after confirmed.
B. during the work, should do the following work will work on the stamping parts, waste cleaning at any time, as you know with hooks or brush, such as special tools, it is forbidden to clean up directly with the hand, work Stainless steel foundry projects, not cutting two pieces of sheet metal at the same time. Timing rotating parts of the oil cup with the hand, and should be filled with lubricating oil. Stretching, should pay attention to add lubricant stretch, and special attention to the cleaning materials. Blow, even burst, finished product have burr, etc., shall be immediately stop work, shut off the power switch, carefully to find the fault part, properly handle to work again.
C. after the completion of the work, should do the following work. Make clutch shut off the power to remove debris clean for oil press and die, and die with presses with anti-rust oil.
