Selection and installation of CNC lathes

CNC lathes, also known as CNC lathes, computer numerical control lathes, domestic use is the largest and most extensive coverage of a CNC machine tools, accounting for the total number of CNC machine tools, 25 percent. CNC machine tools to mechanical, electrical, hydraulic, pneumatic, microelectronics and information, a number of technology as one of the mechatronic product. Has the advantages of high accuracy, high efficiency, high automation and high flexibility such as the workhorses in the machinery manufacturing equipment.

The technical level of CNC machine tools in metal cutting machine tool production and total ownership percentage is a measure of one of the important symbol of a national economic development and industrial manufacturing overall level. The CNC lathe is one of the main varieties of CNC machine tools and CNC machine tools, it occupies a very important position, and for decades has been subject to widespread attention of the world and has been a rapid development.
CNC lathes, turning centers, a high precision, high-efficiency automatic machine. It has extensive process performance, can be processed straight-line cylindrical, the slash cylindrical, circular, and a variety of thread. With linear interpolation, circular interpolation, a variety of compensation function, and played a good economic effect in the mass production of complex parts. Reasonable selection of CNC lathes, should follow the following principles:

A. selection principle
(1) preparation
Determine the typical parts of the process requirements, the bulk of the workpiece, the function is to develop the CNC lathe should have a good preparation, a prerequisite for a reasonable selection of CNC lathes to meet the requirements of typical parts of the process.
Process requirements of the typical parts of the main parts of the structure size, the range of processing and accuracy requirements. Accuracy requirements, ie, the dimensional accuracy of workpiece positioning accuracy and surface roughness requirements to select the control accuracy of CNC lathes. Selected based on reliability, the reliability is to improve the assurance of product quality and production efficiency. The reliability of CNC machine tools is when a machine to perform its functions under specified conditions, long and stable operation without failure. The average failure a long time, even if the failure within a short time can be restored back into use. Choose a reasonable structure, fine workmanship, and mass production of machine tools. In general, the more users, the higher the reliability of the numerical control system.

2. Machine tool accessories and tool purchase
Random machine tool accessories, spare parts and supply capacity, tools, already in operation of CNC lathes, turning centers is very important. Select tools, need to carefully consider the matching of cutting tools and accessories.
3. Emphasis on the control system of identity
Manufacturers generally choose the same vendor's products should at least buy the same control system manufacturers to bring great convenience to maintenance work. Teaching units, due to the need of the students' well-informed, choose a different system, equipped with a variety of simulation software is a wise choice.
4. to choose based on cost performance
Do function, accuracy is not idle, do not waste, do not select and unrelated functions.
5. the protection of machine tools
When necessary, the machine can be equipped with a fully enclosed or semi-enclosed protective equipment, automatic chip removal device.
In the choice of CNC lathes, turning centers, should be considered in the above-mentioned principles.

B. Installation
1. lifting and transportation
Machine lifting and place, you should use special lifting tools provided by the manufacturer is not allowed to use other methods. Does not require special lifting tools should be used to rope in accordance with the instructions provided for parts of the lifting and place.
2. the basis and location
The machine should be installed on a solid foundation, should be located away from the local oscillator; to avoid sunlight and heat radiation; placed in a dry place to avoid the influence of moisture and air. Machine nearby if oscillator, the basis of four weeks must be set to the anti-vibration ditch.
3. machine installation
The machine is placed on the basis of the free state of leveling, and then anchor bolts evenly locking. General machine tools, the level of instrument readings does not exceed 0.04/1000mm for high-precision machine tools, a level not more than 0.02/1000mm. Installation accuracy measurements should be carried out at a constant temperature of measurement tools is subject to a period of constant temperature time before use. The installation of the machine should be trying to avoid so that the machine to produce the forced deformation of the installation method. Installation of the machine should not be casually removed some parts of the machine, the demolition of components may lead to stress within the machine allocation, thus affecting machine tool accuracy.
4. Before commissioning preparation
Machine geometry accuracy inspection, on the whole clean-up. The use of cotton or silk cloth soaked in cleaning agent, not with cotton or gauze. Cleansed machine factory for the protection of the rail surface and machined surface coated anti-rust oil or anti-rust paint. Washing machine the outer surface of the dust. Machine regulations so that oil in the sliding surface and work topcoat.
Carefully check all parts of the machine is required to add the oil, add a little coolant in the cooling tank. Machine hydraulic station, the oil of the automatic lubricating device to the oil level instructions of the provisions site.
Check the electrical control box switches and components is normal, the cartridge circuit boards in place.
Cycle power to the centralized lubrication installed Xuan, filled with lubricating oil lubrication and lubricating oil. Do everything ready before the various parts of the action of the machine.
