With the development of industry, CNC lathe technology has become more and more exquisite. Then how to ensure the accuracy of the size of the CNC lathe processing aluminum material? The following is a brief description for you.
First and foremost, there are several dimensions that must be taken into account in the preconditions of aluminum material as follows.
I. Force majeure factors.
1. The stability of the CNC lathe itself. If it is not a new CNC lathe or CNC lathe after a lot of production and processing without carrying out the condition of regulation, there will be a deviation from the specifications caused by the CNC lathe itself. There are several elements leading to the deviation of the CNC lathe itself as follows.
Mechanical equipment level.
a. AC servo motor and ball screw are loosened in the middle.
b.Ball screw rolling bearing or nut is damaged.
c. Insufficient wetting in the middle of ball screw and nut.
Electrical equipment level.
a.Common failure of AC servo motor.
b. Internal stain of the scale.
c. Common fault of servo motor amplifier.
The main parameters of the system software level can be carried out PMC repair, so omitted to mention.
2. Water cooling deformation after the production and processing of steel parts. Most of this can not be prevented, in the production and processing as far as possible to pay attention to the application of freezing liquid, and its accurate measurement when carrying out when the government, pay attention to the deformation of steel parts after water cooling.
Second, preventable elements.
1. Production process
I think the vast majority of specific production and processing deviations are caused by the production process is not scientific, in order to ensure that the basic production process (such as cutting CNC lathe processing "first coarse after fine, first surface after the hole, first a large number after Chongqing small surface" or tooling fixture application "to reduce the frequency of clamping, as far as possible to use a combination of Fixture" and other basic production process key points), basically, try to avoid the iron pin on the die casting production processing deviation, because the die casting is very good very soft, remove the iron pin is very easy to make the die casting lead to production processing deviation. To learn a lot of CNC machine expertise please add Q group 192963572, for example, in FANUC or Mandarin
Hotel CNC machine tools, playing deep holes as far as possible to apply the G83 command, so that the iron pin can be lined up, and not G73 command.
2. cutting three elements: cutting amount vc, cutting speed f, drilling depth 1ap and CNC insert compensation
This line is really not very good in detail, in simple terms, that is to say, in order to ensure the production and processing quality and damage to the CNC inserts under the premise of adjusting the main parameters of the full use of CNC inserts processability, so that the maximum efficiency of drilling, the least cost of production. In the CNC milling machine, there are also factors such as compensation for blade damage.
3. Manual production program writing and automatic programming in the numerical calculation
In the manual production program writing, measurement appear deviation are common, but nowadays most of the production manufacturing are automatic programming.
4. Tool setting
Inaccurate tool setting are the elements that lead to the deviation of specifications, as far as possible to pick a good edge finder, if the CNC lathe has a fully automatic tool setter you will be stronger, if not edge finder, tool radius compensation it, which means the actual operation work experience.
