Cut the end face and outer circle of the workpiece with one knife (the end face is flat, and the outer circle is turned), then measure the diameter of the outer circle d, and change the roughing thread cutter to cut the thread. Here's how:
The roughing tool (T0X00) is first machined with a hand-cranked pulse generator on the outer circle D after cutting. Use the hand-cranked pulse generator to shake out the workpiece in the positive direction of the Z-axis, and enter the D value (the X-axis of this tool is set to the tool). Make a note of the specific data displayed on the x-axis.
Feed 1 2 mm in the negative direction with a hand-cranked pulse generator on the recorded data displayed on the x-axis. Similarly, the hand-cranked pulse generator is fed in the negative direction of the Z-axis, and the tool can be cut to the workpiece. Enter z0 (the end of the z-axis tooling).
At this time, the rough-turning threading tool is finished.
According to this method, the thread finishing is carried out, and the operation steps are exactly the same as the tool setting method of rough turning tools. In this way, there will be no clasp during the cutting process. Even if there are more tools for cutting, there will be no jamming.
2. Precautions.
The number displayed by the machine is different for each tool when it is aligned to the x-axis. Be sure to record the actual data of each tool. After exiting the X-axis, the X-axis feed data of multiple thread cutting tools must be the same, and there can be no differences.
In the process of tool setting, when approaching the X-axis and Z-axis of the workpiece, it is recommended that the feed gear should be selected for the hand-cranked pulse generator.
CNC system and mold technology restricts the development of terminal industryAlibaba Machinery 2012-12-07 **: China Machine Tool Network Topic: CNC system printing CNC system and the lagging development of functional components has become a bottleneck restricting the development of China's terminal industry.
The domestic market share of domestic mid-range CNC systems is only 35%, while more than 95% of high-end CNC systems rely on imports. The overall market share of functional components in the domestic market is about 30%, of which the market share of high-end functional components is even lower. According to national customs statistics, in 2010, China's imports of CNC systems amounted to 100 million US dollars, and machine tool accessories (including functional components and fixtures) reached 100 million US dollars.

It depends on what material you process, how you enter the knife, how many knives you enter, and what the processing accuracy requirements are.
Strictly or to pass the track and the track, or some other tool for inspection.
This thing depends on what material you are processing, the plasticity of steel parts is relatively strong, and the value will be larger, and there are almost no gray iron parts.
What plastic direct original diameter can be, if you are processing steel workpieces:
The external thread of 50 1 is the diameter and the internal thread is the diameter.
50 The male thread of 2 is the diameter of the internal thread.
The final feed size of the thread is: pitch That is to say, 50 1 of the external thread size 50 1
The above is purely a personal experience, there is no theoretical basis, please forgive me for the mistakes!

CNC lathe: CNC lathe processing is a high-precision, high-efficiency automatic machine tool with digital information to control the displacement of parts and tools. It is an effective way to solve the problems of changeable varieties, small batches, complex shapes and high precision of aerospace product parts and realize efficient and automated processing.
1. The main machine, he is the subject of CNC machine tools, including machine tool body, column, spindle, feed mechanism and other mechanical components. He is a mechanical component used to complete various cutting operations.
2. The numerical control device is the core of the CNC machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, which is used to input the digital part program, and complete the storage of input information, the transformation of data, the interpolation operation and the realization of various control functions.
3. The driving device is the driving component of the actuator of the CNC machine tool, including the spindle drive unit, the feed unit, the spindle motor and the feed motor. He implements the spindle and feed drive by means of an electrical or electro-hydraulic servo system under the control of a numerical control unit. When several feeds are linked, positioning, straight lines, plane curves and spatial curves can be processed.
4. Auxiliary devices, some necessary supporting components of the index control machine tool to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and testing devices.
5. Programming and other ancillary equipment can be used to program and store parts outside the machine.
The machining center has more Y-axes than CNC lathes, and CNC lathes only have X, Z axes.
Friends must be cautious, time is the most important, why junior high school students? Because junior high school students are easy to cheat with their money. >>>More
CNC boring and milling machine is generally a relatively large equipment, and horizontal machining center is the same reason, the current production of CNC boring and milling machine and machining center can basically be universal, but in the processing parts boring machine is limited by relatively little, As for programming, the boring machine is generally fed per revolution when drilling, and the machining center is generally fed per minute. Because the centripetal force of the boring and milling machine is better, the ram can stretch out very long, and it is generally used to process hole parts with high precision and relatively large volume, and the ram of the boring and milling machine is relatively stable. The machining surface accuracy is relatively high, and a good machining center can basically achieve it.
