How to control the cutting amount of CNC lathe reasonably

For metal cutting, processing data, tools and cutting conditions are the three major elements. These determine the machining time, tool life and machining quality. An economical and effective machining method must be a reasonable choice of cutting conditions.Three factors of cutting conditions: cutting speed, feed rate and depth of cutting directly cause tool damage. As the cutting speed increases, the temperature of the tip increases, and mechanical, chemical, and thermal wear occurs. A 20% increase in cutting speed can reduce tool life by half.The relationship between feed conditions and tool wear occurs on a small scale. However, the feed rate is large, the cutting temperature is increased, and the back wear is large. It has less effect on the tool than the cutting speed. The effect of cutting depth on the tool is not cutting speed and feed, but in the micro cutting depth, the rigid layer generated by cutting parameters will also affect the life of the tool.The user should choose the cutting speed according to the CNC lathe processing data, hardness, cutting state, data variety, feed rate, cutting depth, etc. Select the most suitable processing conditions according to these elements. Regular and steady wear is the ideal condition. But in practice, the choice of tool life is related to tool wear, machining size change, surface quality, cutting noise, processing heat and other factors. Stop the discussion on the basis of confirming the processing conditions and requirements. For refractory materials such as stainless steel and heat-resistant alloys, coolant or rigid blades can be used.

How does a vertical machining center work?

In material processing sites, people attach great importance to processing equipment, the application of traditional processing methods usually need to go through complex operating procedures, need a large number of personnel to complete the processing process, although it can also complete the production task, but with the improvement of processing efficiency requirements in various industries, in order to improve the work progress, to complete the processing task in the shortest time. It is necessary to start with the adjustment of equipment and operation mode, so many processing places will pay attention to the application of vertical machining centers.So what is the working principle of the vertical machining center brand? What are the advantages of the device during operation? In the process of processing the workpiece, the use of equipment only requires the staff to process the standard input parameters according to the information, the application of the equipment is very simple, after starting only a simple clamping operation, the equipment will enter the automatic procedure, the operation mode of the equipment is carried out in accordance with the parameter Settings, no personnel assistance is required, so the workflow has been simplified a lot compared with the traditional equipment. Running time is also shorter. What's more, the tool can now be changed at will, and the machine can decide whether to increase the tool or change the machining speed.Now the vertical machining center is equipped with a very large variety of tools, so the equipment can meet the needs of different industries and processing sites, but the staff must understand the working principle and application method of the vertical machining center in detail before the actual operation. Equipment.After the workpiece is once installed in the machining center, the CNC system can control the machine tool according to different processes, automatically select and replace the tool, automatically change the spindle speed of the machine tool, the feed rate and the tool relative to the workpiece's movement trajectory and other auxiliary functions, and complete the multi-process processing of the workpiece's multiple surfaces in turn. And has a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.Vertical machining center refers to a set of vertical machining center with spindle and workbench, which is mainly suitable for processing sheet, sheet, mold and small shell complex parts. The vertical machining center can complete milling, boring, drilling, tapping and cutting threads. Vertical machining center is at least three axis two linkage, generally can achieve three axes three linkage. Some can be five-axis, six-axis control. Vertical machining center column height is limited, box workpiece processing range is reduced, which is the disadvantage of vertical machining center. Vertical machining center workpiece clamping, easy positioning; Easy to observe the tool trajectory, easy to check and measure debugging procedures, timely find problems, stop processing or modification; Cooling conditions are easy to establish and the cutting fluid can reach the tool and machining surface directly. The three coordinate axes are consistent with the Cartesian coordinate system, the feeling is intuitive, and the visual Angle is consistent with the pattern, and the chips are easy to be eliminated to avoid scratching the processed surface. Compared with the corresponding horizontal machining center, the structure is simple, the area is small, and the price is low.

Take you to understand the turning and milling compound CNC lathe and its advantages!

Composite machining is one of the most popular machining techniques in the field of machining. This is an advanced manufacturing technique. Composite machining is the realization of several different processing processes on a single machine tool. Composite machining is widely used and difficult, that is, turn-milling composite machining. The composite machining of turning and milling is equivalent to a CNC lathe and a composite machining.About:Turning and milling compound machine tool is a CNC equipment which develops rapidly and is widely used in compound machine tool. Composite machine tool is one of the important directions of machine tool development. Composite machine tools include turning and milling composite machine tools, turning and milling composite machine tools, milling and milling composite machine tools, cutting and 3D printing composite machine tools, cutting and ultrasonic vibration composite machine tools, laser and stamping composite machine tools. The purpose of the composite is to make the machine multi-functional, one clamping can complete multiple tasks, improve processing efficiency and accuracyAdvantages:Compared with the traditional CNC machining technology, the outstanding advantages of composite machining are mainly reflected in the following aspects.(1) Shorten the product manufacturing process chain and improve production efficiency. Turn-milling complex machining can complete all or most of the processing processes at one time, thus greatly shortening the product manufacturing process chain. On the one hand, it reduces the production auxiliary time caused by clamping changes, and also reduces the manufacturing cycle and waiting time of the fixture, which can significantly improve production efficiency.(2) Reduce the number of clamping and improve the processing accuracy. The number of card loading is reduced, avoiding the error accumulation caused by the positioning reference conversion. At the same time, most of the turn-milling complex processing equipment has an online detection function, which can realize the on-site detection and precision control of key data in the manufacturing process, so as to improve the processing accuracy of the product.(3) Reduce the footprint and reduce production costs. Although the unit price of turning and milling composite processing equipment is higher, due to the shortening of the manufacturing process chain and the reduction of the equipment required for the product, as well as the reduction of the number of fixtures, workshop area and equipment maintenance costs, it can effectively reduce the investment, production operation and management costs of the overall fixed assets.
