Woodworking Engraving Machine Spindle Motor Life

How to choose woodworking engraving machine tool?

1, the nature of the material being cut

Wood cutting is made of solid wood and wood composites. Wood composite materials, including veneer lumber, plywood, particleboard, oriented particleboard, large particleboard, gypsum particleboard, cement particleboard, hard fiber board, medium density Fiberboard, high-density fiberboard, blockboard, glued wood and so on. Some wood or wood composite workpieces are also treated with single or double veneer finish.

2, cutting direction

Solid wood cutting, according to the direction of the blade relative to the direction of wood fiber cutting is divided into vertical, horizontal, end and longitudinal, vertical and horizontal and horizontal cutting.

3, tool rotation direction and feed direction

Depending on the direction of rotation of the machine tool axis and the direction of the feed of the wood workpiece, determine the inclination of the blade on the tool.

4, tool and workpiece stability

The stability of the tool and the workpiece in the cutting process includes several aspects of the content, the stability of the workpiece is the wood workpiece in the cutting process in a smooth feed without jitter. Measures to improve the stability of the workpiece to reduce the workpiece center of gravity and increase the contact area.

5, processing surface quality requirements

Wood surface quality includes surface roughness, geometry and shape position accuracy.

How to reduce the woodworking engraving machine tool beating

During the machining process, if the center of the tool and the center of rotation of the woodworking engraving machine are inconsistent, the radial runout of the tool will be caused, that is, the tool rotation we usually said is different. Further understanding is that the normal high-speed rotation of the tool should be a vertical line, then the heart will become a cone. So that the processing accuracy and the effect must be reduced, the tool will be easy to break. So how to reduce the radial runout of the tool when processing it.

First of all we have to clear the tool and chuck with the chuck and nut with the knife on the method is correct and the quality of the tool itself is the impact of beating factors. In this regard we should pay attention to the chuck and nut cleaning, can not have dust. Knife on the intensity to be correct, too large and too small are not good. There is also a very important tool to extend the length to be small. Spindle motor speed should also be noted when necessary, in the spindle speed requirements are not very high material, such as metal copper, we can choose a reasonable spindle speed, to reduce the radial runout.

Followed by how to reduce the tool radial runout. Why does the tool produce radial run at the time of machining? It is because the radial cutting force exacerbates the radial runout, so reducing the radial cutting force is an important principle to reduce the radial runout. The use of sharp cutting tools: sharp tool for processing the overall cutting force is small, so that the tool by the radial cutting force is small, so you can reduce the tool radial run; tool nose to smooth: When machining, it is possible to reduce the friction of the chip to the tool, which also reduces the cutting force of the tool and reduces the radial runout of the tool. Use the reverse milling during finishing: Note that this is only done during finishing Rough machining or to use the smooth milling, or tool life is difficult to be guaranteed. In the use of reverse milling, the direction of the cutting force is always the tool pulled to the workpiece, so that the tool is more stable in the processing; then use the strength of the woodworking engraving machine tool to increase the strength of the knife can increase the diameter of the arbor, The diameter of the tool bar is increased by 20% and the radial direction of the tool can be reduced by 50% when subjected to the same radial cutting force.

3. How to judge the noise of woodworking engraving machine?

Woodworking engraving machine Stepping motor has a pause every step, there is noise is normal.

At a certain frequency, woodworking engraving machine will also produce the body resonance, issued a significant noise. This kind of noise will not affect the normal use of the machine.

Impact and harmful to woodworking engraving machine noise mainly for the following two categories:

1, the spindle motor is running abnormal noise.

The production of such noise, the spindle bearing quality problems or spindle bearing life has come, or after the quality of wear or damage, then you can consider replacing.

2, abnormal noise when traveling in the axial direction. This phenomenon exists in the X axis.

Mostly axial motor bearing damage or X-axis guide rail lack of lubricants, dirty, too tight, ball wear, ball drop, etc., must be promptly processed.

Four. Woodworking engraving machine spindle selection

Woodworking engraving machine spindle is the most important components of woodworking engraving machine, the advantages and disadvantages of the spindle directly affect the processing speed and precision engraving machine, how to choose high-quality engraving machine spindle is very important, woodworking engraving machine spindle selection points summary Out for the majority of users Reference:

1. If the pursuit of woodworking engraving machine processing efficiency, processing is necessary to speed, while eating knife and large, such as processing solid wood materials, need more than 3KW spindle motor.

2. Woodworking engraving machine spindle motor whether the use of high-precision bearings, if not using high-precision bearings, the performance of the spindle motor for a long time after the high-speed rotation overheating, affecting the spindle motor life.

3. Look at the woodworking machine spindle rotation at different speeds, especially high-speed rotation, the sound is uniform and harmonious.

4. See whether the radial of the spindle engraving machine is forced. The main reference is whether high-speed cutting hard texture of the material. Some spindle can only be cut at a very low speed hard material, otherwise the spindle performance will be seriously lost, after a period of time to affect the spindle accuracy, or even so.
