CNC lathe in the process of processing the most simple problems and
processing difficulties there are the following:
First, how to judge the good condition and service life of the tool?
1. In the active machining process of the machine tool, it is necessary to
use the ear to hear the sound, check or touch the tooltip on time when the
cutting process is stopped, and analyze and judge the surface finish, etc.
Two, how to reasonably choose the corresponding tool according to the
characteristics of raw materials?
1, CNC lathe processing in the process of processing, if the tool selection
is not right, it will lead to unstable processing or processing! And affect the
power, but also does not make good quality. So the selection of tools is very
important, when we process raw materials that are relatively hard raw materials,
we should choose rigid relatively strong knife tip large tools, the machine
should also choose low speed, slow feed, less back to eat, and other criteria to
debug! So when processing raw materials are soft, such as aluminum alloy, nylon
rod, copper, and other raw materials! Then we can improve the speed, feed, back
knife, and the use of the corresponding alloy knife! In particular, the feed is
slow and will form extrusion slag, around the workpiece, not broken slag. Thus,
the power and quality will be greatly affected.
Three, when the process or cutting path is not well arranged to affect the
power how to do it?
Try not to repeat the same knife used many times, to the end of a knife
certainly doesn't have to be the second, and the row knife order program
sequence under the conditions allow, must according to the dao way, as far as
possible the tightening of idle time, reduce unnecessary positioning error,
under the condition of the cutting tool or have no effect on the quality, once
again, the optimization of the process, to reach the best processing condition.
Four, in the processing of thin wall products simple deformation how do?
Such products are a little difficult, some may be divided into many processes
to complete, according to the product requirements, to analyze and judge! Must
use low speed, slow feed, less back to eat three processing elements! And to
choose a small tip, the knife blade is sharp, clamping is also as far as
possible to choose axial clamping (such as pressure screw sleeve), such as using
radial home tight has been deformation state.
