The CNC lathe can process complex workpieces such as straight cylinders, oblique cylinders, circular arcs and various threads, grooves, worms, etc. It has various compensation functions such as linear interpolation and circular interpolation, and is used in the mass production of complex parts. A good economic effect. 2. Numerical control lathes and turning centers are high-precision and high-efficiency automated machine tools. Equipped with multi-station turret or power turret, it has a wide range of processing performance. The CNC machine tool automatically processes the processed parts according to the pre-programmed processing program. 3. The machining process route, process parameters, tool motion trajectory, displacement, cutting parameters (spindle rotation, feed, back tooling, etc.) of the part, and auxiliary functions (tool change, spindle forward rotation, reverse rotation, etc.) , Cutting fluid on, off, etc.), in accordance with the instruction code and program format specified by the CNC machine tool to write a processing program list, and then record the content of the program list on the control medium (such as punched paper tape, magnetic tape, magnetic disk, magnetic bubble Memory), and then input into the numerical control device of the numerical control machine tool, so as to direct the machine tool to process the parts. 4. This whole process from the analysis of the part drawing to the preparation of the control medium is called the compilation of the numerical control program. The difference between CNC machine tools and ordinary machine tools processing parts is that CNC machine tools automatically process parts according to the program, while ordinary machine tools must be operated by humans. As long as the program that controls the action of the machine tool is changed, the purpose of processing different parts can be achieved. CNC machine tools are especially suitable for processing small batches of parts with complex shapes and high precision requirements. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Report John KuoYU 2018-04-18T10:10:19+00:00Added an answer on April 18, 2018 at 10:10 am 1. Theoretically speaking, the process time of groove cutter cutting ring and inner hole of car is shorter. 2. The time-consuming of the outer circle machining, the two end face machining and the finishing of the hole is the same for the entire workpiece, so only the rough machining of the hole is considered. 3. For the convenience of calculation, the spindle speed is 500 rpm (V=65 m/min). 4. The feed rate for drilling and rough turning holes is 0.2 mm/revolution, and the feed rate per minute is 100 mm/min. 5. The maximum diameter of the end face groove is 65 mm, the feed rate is 0.05 mm/revolution, and the feed rate per minute is 25 mm/min. 6. The drilling length is 50 mm (including the length of the drill tip and cone), and the total cutting time is 0.5 minutes. After drilling, the margin is 35 mm, and the total length is 240 mm in six rough turnings, and the total cutting time is 2.4 minutes. The shared time is 2.9 minutes. 7. The cutting length of the end face is 40 mm, and the total cutting time is 1.6 minutes.After grooving on the end face, the margin is 10 mm, and the length is 80 mm in two rough turnings, and the cutting time is 0.8 minutes.The shared time is 2.4 minutes. 8. In actual cutting, the line speed found can be increased, so the process time for cutting the ring groove on the end face can be shortened. 9. In the specific implementation, you must also look at many factors such as the batch size of the workpiece, the cost of the tool and the processing of the inner round block. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Report Bumer Hassan 2018-04-18T10:10:13+00:00Added an answer on April 18, 2018 at 10:10 am CNC lathes are one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, cylinders, and conical threads. It can also perform grooving, drilling, reaming, and reaming. Hole and boring etc.CNC lathes are mainly used for parts processing, including drilling, grooving, polishing and so on. Salaries are in the middle and lower range. As long as you are not afraid of hardship, tired or dirty, the job is still relatively easy to find. Because this industry is mainly a processing industry, it simply means to earn processing costs. It can only increase income by opening the number of processing, and it is susceptible to the direct impact of the current price of raw materials in the market. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Report Aaron Shuai 2018-04-18T10:10:06+00:00Added an answer on April 18, 2018 at 10:10 am Lathe processing is a part of mechanical processing. There are two main types of processing: one is to fix the turning tool and process the unformed workpiece during rotation; the other is to fix the workpiece and rotate the workpiece at high speed to make the turning tool ( Tool holder) horizontal and vertical movement for precision machining. CNC lathe processing usually consists of a control system, a servo system, a detection system, a mechanical transmission system and its auxiliary systems. Drills, reamers, reamers, taps, dies and knurling tools can also be used on the lathe for corresponding processing. Lathes are mainly used for machining shafts, discs, sleeves and their workpieces with rotating surfaces. They are the most widely used type of machine tool processing in machinery manufacturing and repair factories. The materials commonly used in modern lathe processing use aluminum alloy materials. The density of aluminum alloy materials is greatly reduced relative to the density of iron and steel materials, and the processing difficulty of lathe is low, the plasticity is strong, the weight of the product is greatly reduced, and the parts processed by the lathe are greatly reduced. The time that followed is that the cost reduction has made aluminum alloy the darling of the aviation accessories field. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Report Hope Haas 2018-04-18T10:09:59+00:00Added an answer on April 18, 2018 at 10:09 am CNC lathes and turning centers are high-precision and high-efficiency automated machine tools. Equipped with multi-station turret or power turret, the machine tool has a wide range of processing performance, and can process linear cylinders, oblique cylinders, arcs and various threads, grooves, worms and other complex workpieces. It has linear interpolation and arcs. Interpolate various compensation functions, and play a good economic effect in the mass production of complex parts. The Programmable Logical Controller (PLC) is also a general-purpose automatic control device based on the proud processor. It is also called a Programmable Controller (PC) or Programmable Machine Controller (PC). Programmable Machine Controller, referred to as PMC), is used to complete various logical operations and sequence control of CNC machine tools, such as machine start and stop, workpiece clamping, tool replacement, coolant switch and other auxiliary actions. The PLC also accepts instructions from the machine tool operating panel: on the one hand, it directly controls the actions of the machine tool; on the other hand, it sends related instructions to the CNC for processing control and creation. The PLC in the CNC system has a built-in type and an independent type. The internal I type PLC and CNC are combined and designed, also known as the integrated type, which is a part of the CNC; the independent type PLC is produced by an independent professional factory, also known as the exterior type. The operation of the CNC machine tool is realized through the man-machine operation panel, which is composed of the CNC panel and the machine tool panel. The numerical control panel is the operation panel of the numerical control system, which is composed of a display and a manual data input (Manual Data Input, referred to as MDI) keyboard, also known as an MD panel. The lower part of the display is often provided with a menu selection key, which is used to select a menu. In addition to various symbol keys, number keys, and function keys, the keyboard can also be set with user-defined keys. The operator can realize the system management through the keyboard and the display, and input, store, edit and modify the numerical control program and related data. During processing, the screen can dynamically display system status and fault diagnosis reports. In addition, the numerical control program and data can also be imported through the disk or the communication interface box. The machine tool operation panel is mainly used for the operation of the machine tool in the manual mode, and the operation of the machine tool in the automatic mode. There are various buttons and selection switches on it, which are used for the start and stop of the machine tool and auxiliary equipment, the selection of processing methods, the selection of speed and override, etc.; there are also digital tubes and signal display. The operation panel of medium and small CNC machine tools is often integrated with the CNC panel, but there is a clear boundary between the two. The communication interface of the numerical control system, such as a serial interface, is permanent and located on the machine operation panel. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Report Leave an answerLeave an answerCancel reply Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
