National Manufacturing Equipment: CNC Machining Center
Long long agoOnce upon a time, people said that the country is an important weaponIt refers to the imperial jade seal handed down by Qin Shihuang on behalf of the heavenly power
Later, it generally refers to the jade seal carved by emperors of all dynastiesOn October 5, 2016, Sotheby's auction house auctioned the Hotan green jade seal "the treasure of the supreme emperor" used by one party after the reign of Emperor Qianlong in Hong Kong for HK $91.48 million. At that time, the auction aroused fierce opposition from many parties in China.Nowadays, the title of national heavy weapon refers to manufacturing equipment
Manufacturing equipment determines the level of processing and manufacturingThe level of processing and manufacturing is an intuitive expression of a country's national strengthHowever, what we are talking about today is only this kind of national manufacturing equipment
CNC machining centerIt can not only process and manufacture precision workpieces full of mechanical beautyCNC itself is also an exquisite and elegant industrial creation
(just a little loud)DMG GM 16|6 series six axis automatic turning centerThat's so bad
What can this CNC machining center do?Let's say soIt is known as the top industrial manufacture with the highest difficulty in R & D and manufacturing
Which can best reflect the highest level of industrial development of a countryTurbofan engineIt is polished with CNC bit by bit
As for various high-precision metal partsThere are too many to enumerateThere are turning, boring and milling, grinding and grooving
There are punching, gear shaper and testingThe tools that appear are not completely duplicatedA large CNC machining center
CNC can shape the precision and shape of complex workpieces at one time. What you eat is iron, and what you spit out is different work with high precision. However, the time is hundreds of times shorter than before, and the precision yield has been improved exponentially. The most irritating thing is that it also has adaptability and can be updated at any time.For example, in the past, if a master of worm gear wanted to make a good worm, you had to practice it for ten years and eight years. Hey, now if you want to process a completely different part and make a new process, you can sit and drink coffee. All this needs the support of equipment (tools), that is, it depends on how the manufacturing equipment of this manufacturing equipment plays with the equipmentCNC equipment: all kinds of machining tools
A CNC machining centerBe responsible for tool storage and tool change equipmentIt is called tool holder, also known as tool magazine
We all know the English word: tool magazine(in fact, the original meaning of the word magazine comes from the warehouse)To improve the working ability of CNC
In addition to pursuing more precise controlIt is also necessary to increase the capacity of the tool magazine and speed up the efficiency of tool changeThere are many ways to achieve this
According to the number of tools stored in the tool magazine and the tool taking methodCan be divided into different typesThe common ones are linear type, hat type, disc type, chain type magazine and so on
The power turret should be regarded as the smallest and most portable CNC tool magazineThe utility model is composed of a rotary cutter head and a box bodyA motor is installed in the box
The motor rotor is connected to the central shaft of the NC machine toolThe stator is fixed on the box for tool changeDMG BMT power turret with motor
A CNC machining center can install multiple power turretsThe upgraded version of the power turret is a hat type magazineIt is similar to the integration of turret and spindle head
It is a hat type tool magazine that automatically changes tools by moving the spindle up and downWhen the tool on the spindle enters the clamping slot of the hat magazineThe spindle moves up out of the tool
At the same time, the magazine rotates rapidlyWhen the tool to be replaced is aligned below the spindleThe spindle moves down so that the tool enters the spindle taper hole
After clamping the tool, the magazine returns to its original positionThe tool position of hat magazine is still limited (generally 16 34 tool positions)And it's always up and down
It takes up a lot of time and is not efficientIt also affects the working stroke of the spindleHowever, for a universal manufacturing equipment
It is not enough to add several independent tool holdersAfter all, a high-precision CNC machining center needs to coverLathe worker, milling worker, grinder worker, line drawing worker, heat treatment and other links
If you want to finish so much work at one timeDon't hide hundreds of knives with you. I'm sorry to leave the factory, okay!For CNC machining center
Linear magazine and chain magazine are its armed beltsChain magazineLarge CNC machining centers often need to carry hundreds of tools
If you don't agree, you have to take out dozens or hundreds of fancy tools to connect ironChain magazine of traditional armed belt typeStill not all competent
So there is a large combined extended automatic tool changing chain tool magazine(does such a long name seem particularly corrupt?)It is also called central warehouse tool magazine
The motor drives the winding chain at high speedQuickly send the required tool to the specified positionThen it is taken out by the mechanical arm and sent to the main shaft
Exchange positions with the tools that have been removed at the same timeTo save tool change timeWheel magazine of DMG mori
The disc magazine has been developed to the extremeThe cutter bases are evenly arranged around the huge hollow runnerOne cutter wheel can hold 40 60 cutters
In the assembly workshop of DMG moriYou can see the spectacular installation process of five or even six layer cutter wheelsOriginal title: the beauty of tool magazine: the arsenal of CNC machining center
