Common problems and solutions of CNC woodworking engraving machine tools

In the processing and manufacturing of wooden door industry, cabinet industry, furniture industry and other industries, CNC woodworking engraving machine is inseparable from the figure. Among them, the tool plays an important role in the working process of the CNC woodworking engraving machine. Today, Leapion Laser shares 5 common faults and solutions of the CNC woodworking engraving machine tool.

CNC woodworking engraving machine processing stick knife

1. The material does not melt but sticks to the tool

This phenomenon mainly occurs in the processing of metal materials, especially when processing steel. The main reason is that the cutting heat is too large and the cutting speed is too low.

Solution: 1. Adjust the spindle speed and increase the spindle speed;

2. Reduce the feed speed;

3. Improve the cooling method, change the position where the coolant is applied, and add it to the position where the tool is cut out, which has a better cooling effect.

2. The material melts on the tool

This phenomenon generally occurs in the processing of non-metallic materials. The main reason is that the cutting heat is large, which causes the material to melt.

Solution: 1. Replace the sharp tool, which can reduce the cutting heat;

2. Increase the feed rate, the feed rate is increased, and the time the tool stays in one position is reduced, so that the cutting heat received by the unit volume of material is reduced, and the melting of the material is avoided;

3. Reduce the spindle speed, reduce the spindle speed and correspondingly reduce the cutting line speed, so as to reduce the generation of cutting heat and avoid material melting.

Tool breakage in CNC woodworking engraving machine

The reasons and corresponding solutions are as follows:

1. The feed speed is too fast and the speed is too slow: at this time, it is necessary to reduce the feed speed or increase the speed;

2. Too much cutting allowance: the cutting allowance should be reduced;

3. The protruding part of the tool is too long and the clamping part is too small: at this time, the protruding part should be minimized to ensure that the clamping time is more than 4 times the handle;

4. Serious wear on the cutting edge of the tool: change the tool and regrind, or reduce the cutting speed;

5. The accuracy of the fixture is too poor: replace the fixture;

6. Loose spindle or fixture: adjust the spindle or fixture;

7. The processing surface is complex and the column angles are too many: adjust the cutting parameters to ensure the stability of the workpiece;

8. Poor chip removal and serious chip adhesion: reselect the tool and change the cooling method.

Short tool life of CNC woodworking engraving machine

The reasons and corresponding solutions are as follows:

1. The tool used does not match the setting of the machine itself and needs to be adjusted.

Adjust the ratio of rotation speed and moving speed, generally adjusted to about 10:1

2. The processing material is too hard: In this case, it is recommended to use coating or PCD.

The blade of the CNC woodworking engraving machine is easy to crack

The reasons and corresponding solutions are as follows:

1. The feed speed is too fast, the blade is too sharp or the sharp corner is too sharp: at this time, the feed speed should be reduced, and the corner should be chamfered with a diamond file to dull the blade;

2. The accuracy of the chuck is too poor or the installation is poor: replace the chuck, or clean the debris of the chuck;

3. The rigidity of the fixture is too poor and the grasping force is not enough: reduce the cutting parameters;

4. The shape of the workpiece is complex and there are too many dead ends: lower the parameters and programming methods;

5. The installation of the workpiece is not stable: improve the fixture to ensure the stability of the workpiece;

6. Incorrect cutting direction: Climb milling is generally used for cutting;

7. There are impurities in the material: pay attention to the material and cutting speed.

The surface finish of CNC wood engraving machine is not good

The reasons and corresponding solutions are as follows:

1. The feed speed is too fast or the speed is too slow: at this time, it is necessary to reduce the feed speed or increase the speed;

2. Serious tool wear: replace the tool;

3. The precision of the tool after grinding is not high: it is recommended to use a new tool for finishing;

4. Too much chip accumulation: remove the chips and change the cooling method;

5. Incorrect selection of cutting fluid: choose the correct cutting fluid;

6. Large tool vibration: choose a fixture with high rigidity, high precision and strong grip, and minimize the length of tool extension.
