Application of pneumatic products in the machine tool industry

With the rapid growth of domestic machine tools and the continuous improvement of production automation level, the development trend of pneumatic technology in the machine tool industry will mainly be reflected in the following aspects:

1. Standardization

In order to facilitate emergency maintenance and repair, current users generally require products to be replaceable, and even the mounting parts require standard parts. Therefore, products conforming to ISO, VDMA, NFE and other standards will continue to grow steadily.

2, no oil, more environmentally friendly

Foreign equipment generally adopts an oil-free lubrication pneumatic system consisting of a filter, a pressure reducing valve and a valve and cylinder that are not lubricated by oil. The system is pre-sealed with grease in the parts where lubrication is required, and no oil mist is required. Time work without the need to replenish grease, which can reduce fuel consumption, improve the environment, low cost, convenient maintenance and stable performance.

3, compact, modular, integrated

Today's equipment requires more functions in a limited space, so the size of pneumatic components is also required to be more compact and integrated, which has led to the development and manufacture of a large number of new products, such as NORGREN's Twin- The Lintra rodless cylinder (see Figure 3) requires only one quarter of the installed space for the general cylinder; the VM series valve terminal (see Figure 4), the valve body with a width of only 10 mm provides a flow rate of 430 L/min. ～20-bit integration, multiple functions and pressures can be integrated, which is the future trend of complex control.

4, intelligent, networked

With the development of intelligent and networked CNC machine tools, the intelligent and networked pneumatic technology used in the machine tool industry has become inevitable. Take the SMART series of NORGREN as an example: SMART cylinder (see Figure 5) is a master of intelligent cylinders, built-in solenoid valve, speed control valve, provides Fieldbus and ASI interface, and also meets ISO/VDMA standard, with IP66 protection level, maximum speed up to 1.5 m / s; SMART triple piece (See Figure 6), which makes self-diagnosis of the air handling system possible. The failure of most pneumatic systems is due to the air handling system. The SMART triplex effectively solves this problem and it continuously monitors the pneumatic system and At any time, the relevant data can be displayed through the Fieldbus and ASI connection to inform when it is necessary to replace the filter element, the lubricating oil, whether the pressure state is normal, and record the use time, thereby minimizing the failure rate, reducing the maintenance and repair cost, and improving the normal running time and production capacity.

5, high life, high reliability

The most effective way to reduce the failure rate is to use products with good reliability and long service life. For example, the precision sealing spool valve mentioned above adopts gap sealing. The sliding sleeve is hard anodized and has a service life of up to two. More than 100 million times, there is also IP65 dustproof and waterproof grade, which can achieve long-term trouble-free use, which is a model of such products.

The machine tool industry provides the "working machine" to the machinery industry, which is the basis of the machinery industry. The mainstream product of the modern machine tool industry is CNC machine tools. It brings together the most advanced technologies of various disciplines, featuring high efficiency, high precision, high automation and high flexibility. It is developing in the direction of intelligence and integration. It is a contemporary machine. The foundation and core of manufacturing.
