CNC lathe and car centers are a high -precision, high -efficiency automated machine tool.Equipped with a multi -site blade or power bladder tower, the machine tool has a wide range of processing technology, has various compensation functions of straight -line interpolation, arc interpolation, and has played a good economic effect in the mass production of complex parts.How to buy CNC lathes? How to install CNC lathes?
Features of CNC machine tools
1. High processing accuracy
CNC machine tools are processed according to the instructions given by numbers.At present, the pulse equivalent of CNC machine tools generally reaches 0.001, and the reverse gaps and screw spies of the transmission chain can be compensated by the CNC device. Therefore, CNC machine tools can achieve high processing accuracy.For medium and small CNC machine tools, its positioning accuracy can generally reach 0.03, and the repeated positioning accuracy is 0.01.
2. Strong adaptability to processing objects
When changing the processing parts on CNC machine tools, you only need to re -prepare the program. The new program of the losing person Guo Neng realizes the processing of new parts.convenient.For those ordinary machine tools that are generally hand -operated, it is difficult to process or cannot process precision and complex parts, and CNC machine tools can also achieve automatic processing.
3. High degree of automation, low labor intensity
The processing of the parts is automatically completed according to the pre -edited procedures. In addition to placing perforated or operating keyboards, loading and unloading workpieces, intermediate detection of key processes, and observing machine tool operationsEssenceCNC machine tools generally have good safety protection, automatic crumbs, automatic cooling and automatic lubricating devices. The working conditions of the operator have greatly improved.
4. High production efficiency
The range of the main axis of the CNC machine tool and the range of feedback is large, so each process of the CNC machine tool can be used to use the most favorable cutting amount.The structural rigidity of CNC machine tools is good, allowing strong cutting of large cutting volume, improving the cutting efficiency and saving motor time.Because the air -stroke speed of the mobile components of CNC machine tools is fast, the installation time and auxiliary time of the workpiece are less than the average machine tool.
5. Convenient to replace processing parts
When the number of machine tool replacement is replaced by the processing parts, there is almost no need to adjust the machine tool. Therefore, it saves part installation and adjustment time.The quality of the CNC machine tools is stable. Generally, only the first inspection and the sampling test of the key size between the processes, so it saves the time to stop the test.When processing at the processing center is performed, a machine tool is continuously processed by multiple processes, and the improvement of production efficiency is more obvious.
6. Good economic benefits
① Use CNC machine tool processing, which can save line work hours, reduce adjustment, processing and inspection time, and save direct production costs;
② Generally, the processing parts do not need to be made for special fixtures, which saves the cost of process and equipment.
③ CNC processing accuracy is stable, reducing the rate of waste, and further reduction in production costs.
④ A multi -purpose machine can be achieved, saving the area of ??the plant, and saving the investment of the plant.
CNC machine tool classification
Full -function CNC lathe
This kind of lathe has high resolution, fast feed (generally more than 15m/min). Most of the feed adopts a semi -closed circulation DC or AC servo system. The machine tool accuracy is relatively high.Graphic, human -machine dialogue, self -diagnosis and other functions.
Economic CNC lathe
Most of the structure layout of CNC cars is similar to that of ordinary lathe. Generally, the opening -loop serviced servo system driven by stepping motor is generally used, and the control function is used to achieve the control function.The display is mostly displayed in digital tube or simple CRT characters.
Driving center
The running center is based on a full -functional CNC lathe as the main body, and is equipped with a knife library, knife change device, division device, milling power head, and robotic hand. It can achieve multi -process composite processing machine tools.The car, milling, drilling, hinge, and attack threads of the carrier parts have a comprehensive function, but the price is high.
The FMC lathe is actually a flexible processing unit composed of CNC lathes, robots, etc. It can realize the automation of workpiece handling, loading and unloading and processing adjustment.
CNC machine tool installation steps
1. Start up and transport
The rising and position of the machine tool should be used by the manufacturers dedicated lifting tool, and other methods should be used.There is no need for a dedicated lifting tool, and the wire rope should be used in accordance with the instructions.
2. Foundation and location
The machine tool should be installed on a firm basis, and the position should be far away from the source; avoid sunlight and heat radiation; place in a dry place to avoid the effects of humidity and air flow.If there is a source near the machine tool, the anti -vibration groove must be set up around the foundation.
3. Installation of machine tools
The machine tool should be placed on the basis, and the ground foot bolts should be evenly locked in a free state.For ordinary machine tools, the horizontal meter reading does not exceed 0.04/1000mm. For high -precision machine tools, the horizontal meter does not exceed 0.02/1000mm.
4. Preparation before trial transportation
After the machine tool geometric accuracy is passed, the whole machine needs to be cleaned up.Use a cotton or silk cloth with a cleaning agent to clean the rust oil or anti -rust paint on the machine tool and the dust on the surface of the machine.Applying the noodles and working surfaces to make oil oil.
