"Why dointegrated transfer machineneed to shovel flowers?" People who do not know much about CNC lathes generally do not know, see this is not such a question: is the person more powerful than the machine? The small editor who has been involved in CNC lathes for 30 years, saw the spectacle scene after a tool machine factory, looked very strange at the time, and now it is not strange, and saw the technicians doing the shovel flowers by hand, you can't help wondering: "What are they doing?" Can they really use this technology to improve on these currently machined surfaces?" Of course, I know what you're wondering is, are people better than machines? Because it is now in the era of industrialization, manual manufacturing has long ended, and the development of mechanization is not enough to support the current technical capacity? We have adjusted this and summarized the following:

The answer, of course, is no. It is easy for a machine to draw a straight line, but it is very difficult for a person to draw a straight line without the help of auxiliary tools. In other words, it is difficult for humans to compete with machines in the field of processing. However, the machine also has its defects, because the machining accuracy of the machine will only be lost and will not increase, and the tool machine with higher accuracy can only process machinery with lower accuracy than its own. Therefore, to make a machine more accurate than the original machine, you need to start with human effort. This "human effort" is shoveling flowers.

Shoveling, also known as scraping, is a metalworking technique passed down from the Industrial Revolution 200 years ago that machines cannot replace. Shovel flower is the mechanical two mobile fit surface shovel straight, shovel flat, shovel uniform, CNC track sliding shovel flower formed point line surface to help the mechanical accurate movement, but also let the lubricating oil play the intermediary function, avoid early wear, reduce the mechanical life, like the height of ten people supporting the door panel can be evenly divided weight, if someone squatted down without bearing strength, others because of weight concentration more tired... The key to mechanical quality is reliability, the key to reliability is precision, and the key to police uniforms is shoveling flowers. The reason why the shovel can win the precision of the machine by hand is that there is no thermal deformation problem.

In fact, to put it bluntly, the shovel is to use a manual knife to remove substances that affect the mechanical accuracy, so as to correct the error of mechanical processing.

Shoveling flowers is not a simple technique, according to the senior shoveling master, learning shoveling flowers must be internalized into spontaneous movements after countless exercises, thousands of times a day to repeat fine-tuning posture movements, to master the waist force control length and width, the left hand pressure determines the depth, the right hand controls the shoveling flower point, and the center of gravity of the feet to a more smooth body memory.

The gap between the highest and lowest track may be very subtle 0.01mm, it may also be 1mm, it is not average, if the same force, it will not be flat, so every knife strength is different, shovel flowers are not like general art sculpture, as long as a place is not allowed, it will affect the precision of other places. In addition to more than one plane, and there are four or even more to shovel accurate at the same time, more than one surface difficulty is not addition, but multiplication, shovel flowers can only be dug, can not be filled, once the wrong place to shovel again, the other is equal to all white, this is its difficulty.

Finally, a brief introduction to the working principle of shovel flowers: The color developer (generally red or green pink powder) is first applied to the standard fixture (flat plate or straight gauge fixture when you want to shovel V-shaped rail), the coating must be thin and uniform, the thickness is less than 0.005mm, and then the standard fixture coated with the color developer is rubbed on the rail surface to shovel, the color developer will be transferred to the high point of the rail surface, Then use a special flower spatula tool to remove the high points of the color. This action should be repeated until the track surface shows a uniform and consistent transfer, the shovel master will generally strive to reach the standard of 25 points per square inch, greatly ensuring the flatness and run-in of the contact surface.

The above is the content of "integrated transfer machine Why need to shovel flowers". Although in the current process of shoveling flowers, some leveling operations use electric shoveling machines, which are also a kind of manual shoveling flowers, but you can exclude some laborious work, so that shoveling flowers is less tired. There is no substitute for the "feel" of hand-shoveling flowers when you are working on the most delicate combinations.
