There are a number of techniques for speeding up the machining of workpieces when using CNC lathes. Here are some tips for you:
CNC lathe programming skills:
The processing sequence of the parts: first drilling the flat end (this is to prevent shrinkage when drilling); first roughing the car, then finishing the car (this is to ensure the accuracy of the parts); the first machining tolerance with large machining tolerance is small (this is Ensure that small tolerance surfaces are not scratched and prevent parts from deforming).
According to the hardness of the material, choose a reasonable speed, feed rate and depth of cut, I personally summarize as follows:
1. Carbon steel material chooses high speed, high feed rate and large depth of cut. Such as: 1Gr11, choose S1600, F0.2, depth of cut 2mm;
2, hard alloy selection of low speed, low feed rate, small depth of cut. Such as: GH4033, choose S800, F0.08, cutting depth 0.5mm;
3. Titanium alloy selects low speed, high feed rate and small depth of cut. Such as: Ti6, select S400, F0.2, depth of cut 0.3mm.

CNC lathe tooling skills:
The tool is divided into the tool setting tool and the direct tool setting. Most of the lathes do not have a tool setting tool, which is a direct tool setting. The following tooling technique is a direct tool setting. First select the center of the right end of the part as the tool point and set it to zero. After the machine returns to the origin, each tool that needs to be used will be the tool with the center of the right end of the part as zero. The tool touches the right end and enters Z0 to measure. The value of the measured value is automatically recorded in the tool compensation value of the tool. This means that the Z axis is correct for the tool. The X tool is the trial cutting tool. The outer circle of the tool car part is less, and the outer circle value is measured. If x is 20mm) input x20, click measurement, the tool compensation value will automatically record the measured value, then the x axis is also correct; this tool setting method, even if the machine is powered off, the call will not change after restarting. The value of the knife can be applied to the production of the same part in large quantities for a long time, and the turning of the lathe does not require re-tooling.

CNC lathe debugging skills:
After the parts are programmed, it is necessary to carry out trial and error debugging after the good knife. In order to prevent the error in the program and the mistake of the knife, causing the collision accident, we should first perform the empty stroke simulation processing, in the coordinate system of the machine tool. The tool translates the total length of the part to the right by 2 to 3 times. Then, the simulation process is started. After the simulation is completed, the program and the tool are correct. Then the part is processed. After the first part is processed, the self-test is performed and the test is confirmed. , then find a full-time inspection and inspection, after the full-time inspection confirmed that this means the end of commissioning.
