CNC lathe processing need to pay attention to which points? We have a simple understanding of the following:
- Pay attention to the selection of cutting parameters
The cutting speed, feed rate and cutting depth of CNC Lathe will directly lead to tool damage. With the increase of cutting speed, the tool tip temperature will rise, which will cause mechanical, chemical and physical related wear. When the cutting speed is increased by 20%, the tool life will be reduced by 1 / 2. The influence of feed rate on tool wear is smaller than that of cutting speed, but when the feed rate is large and the cutting temperature rises, the tool wear will be greater. Although the influence of cutting depth on the tool is not as great as the cutting speed and feed rate, when the cutting depth is small, the hard layer of the material to be cut will also affect the tool life.
- Pay attention to the tool selection
1) In rough turning, the tool with high strength and good durability should be selected to meet the requirements of large back cutting and large feed rate. CNC programming UG communication Q group: 304214709, want to learn NC programming, get no taste of learning raw materials plus this group Oh
2) When finishing turning, the tool with high precision and good durability should be selected to ensure the machining accuracy.
3) In order to reduce the time of tool change and simple tool setting, machine clamping tool and machine clamping blade should be selected.
CNC machining
- Pay attention to the selection of fixture
1) Although the general fixture is used to clamp the workpiece, the special fixture is prevented;
2) Parts positioning datum coincide to reduce positioning deviation.
- Pay attention to the affirmation of processing route
Machining route refers to the moving track and target of tool relative to parts in the process of NC lathe machining.
1) The machining accuracy and surface roughness requirements shall be guaranteed;
2) The processing route should be reduced to reduce the tool idle travel time.
In the process of NC lathe processing, we should pay attention to the above four points for attention. Only by choosing the most suitable NC lathe processing mode can we improve the processing efficiency and accuracy of NC lathe processing.
The above is CNC lathe processing need to pay attention to a few points, I hope to help you.
