CNC numerical control lathe processing some of the skills and knowledge sharing

Programming skills because of CNC numerical control lathe factory processing products are of high accuracy, so need to consider when programming the following:

< br / >

1. Parts processing order:

< br / >

hole first, then whisk flat ( This is to prevent hole shrinkage) ;

< br / >

first rough turning, and then the premium ( This is to ensure the accuracy of the parts) ;

< br / >

machining tolerance for the first time, and finally a small machining tolerance ( This is to ensure that the surface of the small size tolerance will not be scratched and prevent the deformation of parts) 。

< br / >

2。 According to the material hardness to choose reasonable speed, feed and cutting depth:

< br / >

1) Carbon steel material selection high speed, high feed, deep cut. For example: 1 gr11, choose S1600, F0. 2, the cutting depth of 2 mm;

< br / >

2) Choose low speed, low feed and small cutting depth. For example: GH4033, choose S800, F0. 08, cutting depth 0. 5毫米;

< br / >

3) Choose titanium alloy low speed, high feed and cutting depth. For example: Ti6, choose the S400, F0. 2, the cutting depth of 0. 3mm。 Parts processing, for example: materials for K414, this is a special kind of hard material. After many tests, the final choice is recent, F0. 1 and cutting depth 0. 2, which can then be processing of qualified parts.

< br / >

two, knife art

< br / >

into instrument of tools and cutting tool directly. Most of our factory without cutting tool of lathe, for the straight knife, the straight knife techniques are as follows.

< br / >

first, choose the right end face of parts center as a tool, and it is set to zero. Machine after the return to the origin, you need to use every tool in the center of the right end face of parts to zero. Input Z0 and click the right side, measuring tool cutting tool will automatically record tool repair value, which means that the positive Z axis of a tool, X knife trying to cutting tool, cutting tool car cylindrical parts less, in automobile cylinder numerical x20 ( For example, X 20 mm) Input signal for the measurement, click on the measurement, knife value will automatically record the measured values, and then based on the X axis; This way, even if the machine is powered on, the call to restart still does not change the value of the knife can be applied to a large number of production of the same parts for a long time, don't need to knife during the lathe to shut down.

< br / >

3, debugging technique

< br / >

each part in the program, and want to learn programming and did not found a way to add the qq group of 192963572 can help you, please try again after debugging good debugging, to prevent errors and mistakes on dao, leading to collapse, should be in travel simulation processing, advanced and the style of the free face cutting tool in the machine tool coordinate system to the right of translation, a total length of 2 - as a whole 3 times; Then start simulation processing, through simulation processing after the confirmation process and knife right, then to start processing parts, finished in the first part, first of all to self-check, confirm qualified, and then find the professional inspection, confirmed full-time after inspection qualified, would mean the end of commissioning.

< br / >

4, complete parts processing

< br / >

parts first trial cut, after the completion of the upcoming mass production, but the first thing is not equal to the whole batch of qualified parts of parts to be qualified, because in the process of machining, because of the different materials can make the cutting tool wear, the processing of soft materials, tool wear is small, hard processing material, tool wear fast, therefore in the process of machining, to regular check on a regular basis, timely knife value increase and decrease, and ensure the parts are qualified.

< br / >

parts, for example, processing materials for K414, processing a total length of 180 mm, because of the special hard materials, processing of tool wear very fast, from the beginning to the end, because the tool wear can produce 10 - 20 mm, so we have to artificially increase the 10 - in the program 20 mm, in order to ensure the quality of the parts.

< br / >

all in all, the basic principle of processing is: to rough machining, removing the redundant materials on the workpiece, precision work again; Should avoid vibration in the processing. To avoid the thermal denaturation, in the process of workpiece machining vibration due to a variety of reasons, may be too much load; May be the machine tool and the workpiece resonance, also may be out of machine tool rigidity, or is caused by the cutting tool passivation, can reduce vibration through the following methods. Reduce the transverse feed and depth of processing and inspection.

< br / >

are present in just about every facet of modern life.

Zhongshan JSTOMI CNC Machine Tool Co., Ltd. take prudent risks and work together to assure our success and profitability in the future.

People tend to want what they perceive they cannot have. Making JSWAY seems exclusive or as if it will go out of stock if they don't act quickly often makes it more enticing to the consumer and increases the likelihood that they will buy in.
