In order to carry out high precision and high quality slow-walking wire cutting processing, the environmental stability must meet the requirements of the specified, there should be no direct sunlight or airflow, temperature changes should be monitored. The temperature range of machine tool to ensure working accuracy is 20±3℃. If the temperature difference is large, it will affect the machining accuracy and surface roughness. Next Xiaobian to introduce the reasons for the low speed of slow wire processing? What are the factors that affect processing efficiency? Welcome to read!

The reason for the low processing speed of slow walking wire?

1. Not processed according to the standard process, the distance between the upper and lower nozzle and the workpiece is higher than 0.1 mm - veneer as far as possible.

2. The created procedure file is incorrect. - Input relevant processing requirements correctly and generate reasonable process documents.

3. The modification of machining parameters, especially the excessively low P and I values, will lead to the significant reduction of machining speed. The discharge process parameters need to be modified reasonably.

4. The flushing state is not good, and the punching hydraulic force cannot reach the standard. If you really can't veneer processing, it is necessary to understand the processing speed correctly.

5. The workpiece deformation leads to the unstable discharge state in the process of processing, especially in the process of trimming. - Reasonable arrangement of process and control of material deformation.

6. If ACO(Automatic process optimization) is selected in the parameter, the processing efficiency will be reduced when the processing is unstable. - The ACO function can be cancelled when the cutting is stable.

7. For the workpiece with large Angle, the use of high-precision parameters can obtain higher accuracy, but the efficiency will be reduced. Reducing STR value of Angle strategy appropriately can improve the machining speed.

8. Mode 30 processing, poor discharge stability, slow speed -UHP modify the parameter, can increase 2 values.

9. Trimming is slow. - The relative processing amount per cut can be slightly reduced, and the offset of the main cut can be reduced by 0.005mm to 0.01mm to improve the trimming speed.

10. Main cutting efficiency is lower than before. - Maintain machine tools in time.

What factors affect processing efficiency?

There are many factors that affect the efficiency of slow - walking wire cutting. If inefficiency occurs in the process, the following two factors can be considered.

1. Limited by the structure and clamping of parts, it can not be effectively flushed into high pressure water.

At this point, it is up to you to see if the cut part can be improved from the fixture. Some parts are affected by the support fixture, the bottom surface is raised, some parts are affected by the position of the pressure plate and clamping screws, and have to raise the upper nozzle. Some operators are afraid of touching the nozzle, and do not drop the upper nozzle to the low point. If the low surface is raised, see if you can use a jig with the jig support surface on the same plane as the workbench, or if the workpiece is clamped directly onto the workbench.

Affected by the screw plate and whether the parts can be clamped with a clamp; For parts where the operator is concerned that the upper nozzle is not falling to a low position, a 0.1mm gauge can be prepared as required. For the parts that cannot be effectively flooded with high pressure water due to the limited structure, the cutting energy can only be reduced, so it is necessary to correctly understand the cutting efficiency.

2. Related to wire transport system (related to maintenance)

1) Check whether the cooling water of the conductive block is normal. In particular, whether cooling water for the lower conductive block is present, as the copper will fall off during the cutting process. After long-term use of the machine tool, it may block the cooling water of the conductive block, or even the flushing of the nozzle processing, which should be cleaned and dredged;

2) Whether the lower regulating wheel on the lower arm rotates flexibly; Inspection and cleaning;

3) Whether the wire collecting wheel is normal;

4) Check the tension and speed of the silk, and adjust it if necessary;

5) Check and clean the guide wire nozzle and conductive block.
