At first, I wanted to write a history of the development of global machine tools, but due to the large history, many contents are difficult to verify, so I decided to focus on the Zhejiang Yuhuan machine tool industry that I am more familiar with. Although the history of Chinese machine tools is long, but I know more about Yuhuan this small island town.
According to his father’s description, in the 1960s, Yuhuan already had state-owned factories, such as Supor’s predecessor, Shuangxi Pressure Cooker, and Qinggang Agricultural Machinery Factory. The machine tools used at that time were mainly the model 6140 hard rail lathe, which completely relied on manual operation by workers. Over time, such machine tools gradually fade out of the market. The machine tools used at the time are shown in the figure below:
I used to operate this 6140 hard rail lathe from northeast China in the summer vacation of middle school, it does not have a CNC computer, whether it is the X-axis, Z-axis, tail seat, knife holder, chuck clamping and loosening must be completely rely on workers to complete manually. At present, such lathes are rarely seen, and it accompanied the beginning of the jade ring industry. In the late 1970s and early 1980s, with the decline of state-owned factories, many private factories appeared in Yuhuan. The craftsmen began to develop small machine tools suitable for mass production – instrument lathes.
In the picture, the clamping method of the main shaft of this instrument lathe is still in use today, and the other two with iron discs are X-axis and Z-axis, driven by workers pulling the handle connecting the iron disc.
At the beginning of the 21st century, CNC lathes have begun to popularize, the programmed program into the CNC computer, complete the knife can start production, at this time the mass production of products began to have a prototype, jade rings have also entered the economic rise period.
CNC0640 is an epoch-making machine tool, from manual to programming, the early model will be equipped with four-way electric tool holder, while the later model will use fixed tool holder.
At this time, the machine tools produced by Yuhuan entered the era of comprehensive numerical control.
Our main model will now use the whole slant bed body and the slant bed saddle modelhttps://hengjiucnc.com/the-difference-in-casting-structure/, this blog has a detailed introduction about the structure of castings.
HJ35 is currently a walking machine tool of Hengjiu Intelligent, the structural performance is very stable after many optimizations, HJ35’s current output limit is 1000 / year, after exceeding this
output we can not guarantee the quality of lathes.
Finally, we should introduce the current machine tool industry more concerned models, CNC turning center machine tools, the difference between this machine tool is also very large, cheap only 150,000 yuan, and expensive need 600,000 yuan and higher prices.
At present, after optimization through internal audit allowed to export H06Y CNC turning center machine tools, is a more representative model, for foreign customers CNC system use Fanuc or Siemens, and the domestic version uses Fanuc and Taiwan’s new generation.
In fact, H06Y series belongs to the single spindle single rotary tower turning and milling composite CNC machine tool, our product sequence also has double rotary tower single spindle and double rotary tower double spindle turning and milling composite CNC machine tool, currently only sold in China, internal research institute ZhangDangbo engineers audit passed to enter the official website allowed to export.
40 years of accumulation and market feedback, we can accurately understand what CNC machine tools the current market needs, how to do the CNC machine tools needed by the market; every new model research and development we need to demonstrate, just like doing math problems when sketching, find the most reasonable plan.
This paper tells my historical understanding of the home machine tool industry, Yuhuan has a year to sell 120,000 CNC machine tools record, but there is always a problem that our output is very brilliant, but when can our quality and performance be ranked in Asia? Even the global rankings, obviously long. Bravely face their own real ability, with objective facts and technical accumulation for customers and friends to solve production problems, technology without bends overtaking.
