Flat grinding is a model with the greatest potential for evolution among grinder-type machine tools, and it has shown four major changes in the development process:
1. Environmental protection requirements are getting higher and higher.
Among the exhibits on display, most of the machine tool products use fully enclosed housings, and there is absolutely no chipping or cutting fluid splashing. On the other hand, the display of a large number of industrial cleaning machines and cutting fluid processing machine systems also reflects the increasing requirements of modern manufacturing for environmental protection.
2. High-speed, compound, high-precision, and high-rigidity are still the main tunes of the development of metal cutting machine tools, but there are new changes.
Compounding has changed from being compounded to compounding for practical and efficient considerations, such as turning, milling compounding, turning, milling, drilling compounding, milling machine and electric spark compounding; from a functional point of view, compound machine tools are aimed at It is very flexible and is considered for certain types of parts; from the point of view of accuracy, machine tools with positioning accuracy <2μm and repeat positioning accuracy ≤ ±1μm are everywhere; from the perspective of spindle speed, the spindle speed of 8.2kW is up to 60000r/min, and that of 13kW is up to 42000r. /min, high speed is no longer a proprietary feature of low-power spindles; from the perspective of rigidity, machining centers that can process 60HRC hardness materials have appeared.
3. The concept of fully automatic has changed.
The traditional fully automatic machine tool uses a pneumatic or hydraulic manipulator to automatically load and unload workpieces. Nowadays, real multi-joint tandem machines are used to realize the loading and unloading of workpieces, including the stacking of finished parts. . The scope of control is enlarged, the flexibility of the assembly line is strengthened, and the auxiliary supporting machinery is greatly reduced.
4. The modular design has been thoroughly applied in machine tool manufacturing.
The modular design of horizontal series, vertical series, full series, and cross series, whether it is Japanese machine tools represented by Okuma and Makino, or American machine tools represented by Haas, Cincinnati, etc., the appearance looks exactly the same, but the function is complete. Different, many of the modules are universal.
