Although the Machining Efficiency of the CNC Lathe is High, the Following Six Points cannot be Ignored

Numerical control lathe processing technology with the ordinary lathe processing technology is similar, but because the numerical control lathe is a one-time clamping and then achieve continuous automatic processing to complete all the turning process, in numerical control lathe processing should pay attention to the following six points:

1, the choice of cutting amount needs to be reasonable

Cutting dosage (AP, F, V) selection is reasonable or not for can give full play to the potential of the machine tool and the cutting performance of the tool, in order to achieve high quality, low cost and high yield, safe operation has a decisive role, in the rough machining, hand is considered to be a large amount of AP back eating.Second to select a larger feeding f, v, finally determine a suitable cutting depth increase turning ap can make feed back the number of less, increase the feeding f can be helpful for chip breaker, so, according to the above principles, choosing rough machining, cutting dosage to improve production efficiency and reduce the loss of the cutting tool and reduce the manufacturing cost is very good;In finish machining, the machining accuracy and surface roughness requirements will be high, machining allowance is not big and more uniform, so choosing precision cutting dosage, should consider how to guarantee the quality of processing, and on this basis to improve productivity, so the precision turning should choose smaller amount of turning the AP with feeding F,Select the tool material with high cutting performance and appropriate geometric parameters, as far as possible to improve the cutting speed V;

2, reasonable choice of tools

A, in the rough turning, the choice of high strength, good durability of the tool, to meet the rough turning of the large knife and large feed requirements;

B, in the precision turning, to choose high precision, good durability of the tool, because to ensure the processing accuracy of parts;

C. In order to reduce the time and procedure of tool change, machine clamp knife and machine clamp blade should be used as far as possible;

3, reasonable choice of fixture

A, should try to choose a general type of fixture to clamp parts, avoid using special fixture;

B. Positioning datum of parts should be overlapped to reduce positioning error;

4, fixture installation should be reasonable

Now, the hydraulic chuck and hydraulic clamping cylinder connection is mainly by the pull rod to complete, the hydraulic chuck chuck critical point is: the use of a wrench to remove the hydraulic cylinder above the nut, remove the pull pipe and extracted from the back end of the spindle, and then use a wrench to remove the chuck on the fixing screw, can remove the chuck;

5. Determine the reasonable processing route

Processing route usually refers to the Cnc Machine tool processing process, the relative movement of the tool parts and direction, the need to meet the two points are: the need to ensure the machining accuracy and surface roughness requirements of the feed route;Should be as far as possible to shorten the processing route, reduce the empty travel time of the tool;

6. The correlation between the processing route and the processing allowance

Today, though CNC lathe has been significantly used in the field of mechanical processing, but also is still popular, general should speak of too much allowance on blank, especially with allowance of forging, casting hard cortex arrangement on universal car for processing, if must use the numerical control lathe processing, need to pay attention to the application of flexible;
