The grinder is a national 863 support project in 2008.The machine tool adopts the grinding method which is based on the grinding point cut. It does not need the auxiliary mechanism such as eccentric fixture, indexing device and so on. Using imported spindle system, the maximum speed of CBN grinding wheel can reach 120m/s. We have developed the interpolation software of the crankshaft cutting point tracking and grinding, and the grinding point of the grinding wheel is always following the rotation of the crankshaft to realize the high precision grinding of the crankshaft. The feed of the grinding wheel is driven by straight line, which has the characteristics of high acceleration response. At the same time, the rigidity and the sensitivity of the grinding wheel are improved by using the sel...

2016 Hunan machine tool industry enterprise investigation documentary -- take the new Hunan machine tool

From September 2016 to October, Hunan province machine tool industry association president Mr. Xu Shixiong led the team in the lead, the move Changsha, Xiangtan, Ningxiang, Yueyang and other places, visit Xiangtan three peak of CNC machine tools, machine tools, Changsha South Yueyang Kim Bo Long science and technology, Hunan machine tool, Changsha LIANLI, Huda Haijie precision machine tool manufacturing industry etc. enterprise. Xu president and his party to listen to the report on the development of business operations, the difficulties faced by the enterprise information and guidance. He encouraged enterprises to strengthen confidence, vigorously carry out the transformation and upgrading, efforts to promote intelligent manufacturing, take a long way to the development of Hunan machine tool industry in the long march.

Xiangtan three peak CNC machine tools

Xiangtan three peak CNC machine tool is a research and development, production and sales of precision grinding machine, memory type horizontal axis grinder, CNC grinding machine and high speed spindle. Into the shop, site clean, tidy and orderly busy personnel equipment, workshop 6S management level so that visitors to praise, Hunan machine tool enterprises are able to pay attention to and if so to promote, this is also a big industry to solve common problems and the formation of industry a unique landscape! Workshop on the left side, neatly arranged a number of ten surface grinding machine, deep gray base with a local orange paint, personal feeling, its appearance in the process of design and make considerable progress. It is reported that this is a batch of equipment to be exported.

Xiangtan three peak workshop

In recent years, Xiangtan three peak international trade market share is rising year by year, the company's growth is better. President Xu expressed appreciation for the enterprises in recent years the achievements and breakthrough of enterprises in the market and put forward suggestions of technical team management: we are not lack of market, but the market can not meet the technical requirements, the so-called supply side reforms. The only way to do a good job of artisan spirit, increase investment in technology to create new products is our only way out. For the management of the technical team, Xu president requires attention to team building and increase the training of the internal forces, technical departments to assess the market linked to the development of strict implementation of rewards and punishments program.

Changsha Southern machine tool and Hunan long machine technology

Changsha Southern machine and Hunan Changji science and technology are now experiencing the process of Phoenix from the ashes. They are inherited from the original Changsha machine factory (the year Chinese machine tool enterprises eighteen Arhats) the orthodox "royal blood," focus on the R & D of broaching machine manufacturing. Under the new era, they are committed to the transformation and upgrading, increase R & D investment, through the transformation and upgrading of traditional broaching machine products, online detection, collocation by manipulator automation equipment and strive to gain new broader market.

Changsha South machine, broaching machine

After visiting two enterprises and enterprise management team meeting, president Xu pointed out that both the Changsha machine second restructuring, or the South machine second business, to the person in charge of the enterprise has brought a lot of pressure, but from the current situation, the bosses have withstood the pressure to go. Get rid of the shackles of all as long as we can move forward with ease. Moreover, the two companies have a good historical accumulation and industrial base, which is the most valuable asset of the long machine. President Xu also suggested that in the current industry economy is not very good, the development of enterprises must be "stable" word at the head, the money spent on the edge, outstanding product innovation.

In the course of the investigation, we found that there is one thing in common: the team building of the enterprise is improving day by day, the division of responsibilities of each department is clear, and the cohesion of the team is very strong. And this is not all good foundation and source?

Due to historical reasons, the Changsha machine tool plant two restructuring, the development of its industry will be affected and even faced an embarrassing situation of development. However, the trend of the historical development of rolling forward, the new things will inevitably replace the old things, this is the ancient history of the law. Fortunately, the spirit of the eighteen Changsha machine tools can still be inherited. A new generation of "machine" is a firm belief, the morale of the rainbow, walking in the industry revitalization and development road.

Yueyang gold Bo machine

Yueyang Jin Bo Machine Tool Manufacturing Co., Ltd. is the original Yueyang machine tool plant after the reorganization of the restructuring of independent research and development, design, manufacture, sales and service in one of the production of metal cutting machine tools of new enterprises. Yueyang machine tool factory was once the country's designated small vertical car manufacturing enterprises, with the north of Qigihar, a large scale car into a North and south two pattern, a sensation. His history and similar to the Changsha machine tool factory, also has a glorious past and the throes of reform.

After the restructuring of the establishment of the Yueyang Jin Bo machine tool is still committed to the production of single column beam lifting, ordinary type, frequency conversion, digital display and CNC vertical lathe. But at present, it is faced with the dilemma of development, there are problems in the management strategy of the enterprise, but also the bottleneck of the technical breakthrough.

President Xu line person in charge of the enterprise to listen to report pointed out that enterprises should first breakthrough is to solve the technical problems, from the product to pay to provide complete solutions for customers, enhance the level of automation products. At the same time, to study our competitors, to tap new customer markets.

As the old Yueyang machine tool factory, the development of today's Yueyang Jin Bo, thanks to a new generation of Hunan machine tool people's heritage
