At present, mechanical processing can be divided into two categories according to production batches: one is single piece, multiple varieties, and small batches (referred to as small batch production); the other is single piece, multiple varieties, and small batches (referred to as small batch production). The other is small varieties and large batches (referred to as mass production). Among them, the former accounts for about 70-80% of the total output value of mechanical processing and is the main body of mechanical processing.
Why is the production efficiency of the same machine tool different several times? The conclusion is that the fixture selected for the CNC machine tool is inappropriate, which greatly reduces the production efficiency of the CNC machine tool. Today, the metal processing editor will introduce in detail the reasonable selection and application of CNC machine tool fixtures.
How to improve the utilization rate of CNC machine tools? Through technical analysis, it has a lot to do with the use of fixtures. According to incomplete statistics, the proportion of unreasonable fixtures used by domestic CNC machine tools is as high as 50%. As of the end of 2010, the number of CNC machine tools in my country has reached close to one million, which means that more than 500,000 CNC machine tools have been "worried" due to unreasonable fixture selection or improper application; from another perspective, CNC machine tool fixtures There is still a lot of work to be done in its selection and application, as it contains considerable potential economic benefits.
Small batch production cycle﹦Production (preparation/waiting) time + workpiece processing time Since the "workpiece processing time" of small batch production is very short, the length of the "production (preparation/waiting) time" is crucial to the processing quality of the workpiece Impact. processing cycle. If you want to improve production efficiency, you must find ways to shorten production (preparation/waiting) time.
