2011 China's future development trend of machine tools

The development of machine tools in the future is inseparable from the development needs of the future manufacturing industry. For example, the development of energy, resources, food, medical engineering, communication technology and automotive industries has a great impact on the development of machine tools in the future.

However, as a whole, the future development direction of machine tools must be as follows: to provide overall manufacturing solutions, comprehensive and efficient equipment, and sustainable.

Equipment in industries such as energy, resources, and agricultural machinery are generally large machinery. When processing these equipment, the machine tool needs higher spindle torque, higher spindle power and larger working space. The specific requirement for the machine tool is to have more custom functions instead of specific machines.

Equipment in the medical engineering, communication technology and other industries are generally small devices. The components of these devices are getting smaller and smaller, the structure is more and more compact, and different cutting environments are required during processing. Sometimes it is necessary to process difficult-to-cut materials such as titanium alloy. Therefore, the processing equipment requires higher precision and rigidity. In terms of specific production requirements, medical engineering (targeted solutions) requires smaller and higher quality. The field of communication technology requires smaller size and higher cost competitiveness.

For the automotive industry, it is generally a highly integrated product that requires integration of various manufacturing technologies in a small space. This requires new processing techniques to process new metal materials, and new processing machinery is needed to process new materials like fiber materials. The requirements of the automotive industry for machine tools are that they can be assembled and assembled in the future using one machine. In terms of machine tool deployment, the machine tool is required to have more processing space and is suitable for mass production.

Looking at the machine requirements of the different types of industries mentioned above, future machine tools should meet the following basic requirements: smaller accuracy errors, reduced energy consumption, shorter processing times, higher overall equipment efficiency and sustainability.

There are different specific requirements for different products: different sizes, a wide range of products, and processing of new materials.

In order to meet the specific requirements of production and take advantage of scale, the economics of machine tools must be changed. The modular customization of machine tools is the future development trend. Customizable functions can improve the economics of machine tools and facilitate large-scale deployment.

In the future, machine tools are not just individual machines, but a holistic solution that can be customized. Therefore, the future development trend of machine tools is a customizable, modular manufacturing and overall solution.

Machine tools as a whole manufacturing solution, including machine tools, tools, clamping devices and the machine itself. In the face of specific production requirements, future machine tools need to improve the efficiency and sustainability of integrated equipment.

In summary, there are two trends in the development of machine tools in the future: to the complete development of the overall manufacturing system to meet the specific requirements of customers; to improve the overall efficiency and sustainability of the equipment.

Future machine tool manufacturing
1. Manufacturing of future machine tool spindles
The following improvements should be made in the manufacture of the crankshaft: grinding instead of grinding; crankshaft special tools; tailor-made clamping devices; modular turning centers.

2. Manufacture of machine tool connectors
The machine tool design has established a number of independent interchangeable components. Modular production allows different components to be replaced according to different production tasks to meet different production requirements. The customizable design facilitates machine tool buyers.

The modular design of the machine tool connector allows the user to customize their production equipment according to specific production tasks, which is more conducive to large-scale deployment and lower production costs. Overall equipment efficiency
To improve the production efficiency of the equipment and reduce the processing cycle, the following three aspects can be adopted: the primary processing time is faster; the secondary processing time is faster; and the service concept is improved.

Improving the availability of equipment can be achieved through two components: components for diagnosis and prognosis; and improved service concepts.

Primary machining time can be reduced by improving machine and tool technology, which can be improved in the following areas: high speed milling; coated tools; high performance spindles; new machine concept (ie dual spindle direct linear drives).

By reducing workpiece and changing tools, repositioning, and processing time of the workpiece and tool handling system to reduce secondary processing time, improvements can be made in the following areas: improvements in clamping devices; integrated tool magazines; integrated workpiece handling.
Increasing the availability of the machine can enhance the machine's ability to diagnose and predict, such as reliable predictions that predict the machine's failure in a particular work environment.

The first stage: constant work behavior; the second stage: verifiable progressive wear; the third stage: gradually increase the machine before high wear.

In the specific production process, the services provided by the manufacturer are also important aspects to improve production efficiency, such as improving the overall equipment efficiency of the user, developing and maintaining the intelligent activities of the machine tool, and providing technical services suitable for the customer.

Specific services include: improved service concepts, service hotlines, data transfer, conference connectivity, remote control, remote diagnostics, remote services, customer service training, availability, response time agreements, maintenance and maintenance contracts, call and response preparation, Customer-facing on-site service and preventive maintenance.

Machine tool sustainability
The sustainability of machine tools is an important aspect of future machine tool development, and sustainability can be redefined by improving the concept of combined machine tools, preferably by improving energy efficiency.

The sustainability of the machine tool can be implemented in the following specific aspects: the use of more advanced environmentally friendly and energy-saving processing methods (such as: dry processing); the use of new technologies (such as coated tools) in the maintenance and maintenance of the tool; Spindle (eg energy recovery, local energy storage); machine (eg machine sleep). Machine tool energy consumption
The energy consumption of the machine tool is exemplified by the machining center:

10 years, 3 classes
=10×3×2000h=60000h

Consumes 17kW × 0.08 / kWh

=1.36/h=81600/working hours
For every 1kW of consumption, you can save 4,800.

The “sleep mode” of the machine tool: machine downtime in the process of wasting energy; the switch of consumers with huge energy saving potential; the comprehensive energy consumption can be reduced to as low as 5%.

Dry cutting/minimum lubrication is used in the process: suitable for dry machining; economical.

Objective: To analyze the operation of wet process switching to dry machining; dry machining process development; tool development; technical planning and system planning.

to sum up
1. The machine tool will be dispersed in the future (power consumption, size, many sizes);

2. Machine tool manufacturers need to provide a holistic solution;

3. Product specific processing technology;

4. Enhanced overall equipment efficiency;

5. Enhanced sustainable development.

In the future, it is very important to provide a complete solution for the customer, and the customer will be treated as a system-specific manufacturing system.
