Causes and judgments of tool wear in woodworking engraving machine

The discrimination of whether the tool of woodworking engraving machine can wear:
1, the tool can wear, the amount of wear, the most direct way to distinguish is to listen to the sound, if the cutting sound is very heavy or screaming, to clarify the tool's processing state is not normal, then you can stop the analysis, if you remove the tool Self-quality problems, tool clamping problems, and knife parameter problems. At this time, it should be able to determine that the tool is worn out, the demand is suspended, and the tool is changed.
2. After the machining state of the machine tool is used to determine the wear condition of the tool, if the machining parameters and cutting amount are set properly, the machine tool vibration during machining is very large, and “WONWON” is issued. At this time, it can be confirmed that the tool has reached a sharp wear state. Need to change the tool.

Characteristics and classification of spindle motor for wood engraving machine

 As the centerpiece of the carpenter carving machine, the spindle motor is the accessory. The spindle motor is the main component of the computer engraving machine, and its function has a major influence on the function of the computer engraving machine. The machining spindles are divided into two categories: fine machining spindles and high power cutting spindles.

1. The precision machining spindle features low noise, high speed and high precision. It is suitable for processing special precision workpieces such as stamps, nameplates and badges. This type of motor is a high-speed variable frequency motor with low power, usually below 250W. The defect is that the ability to cut thick data is poor, and it is not appropriate to cut thicker data.

2, high-power cutting spindle, the first is used for cutting, high-power carving, characterized by high power, cutting ability, special suitable for cutting words, three-dimensional characters, of course, can also make badges, nameplates, seals and so on. Such high-power spindles can be generally classified into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main difference is: A, the brushless inverter motor has a high speed, and the shifting limit is 700-60,000 rpm. The ordinary brushed AC motor Highest speed does not exceed 24000 rev / min: B, brushless inverter motor has high torsion precision, low wear, low noise, its noise is much lower than brushed AC motor; C, brushless inverter motor stall characteristics Well, because there is an extraordinary current limiting circuit on the inverter, the short-duration of the stall will not destroy the motor, and the brushed AC machine will quickly destroy the smoke when it is overloaded or blocked, and it will not be repaired; D, no The brush frequency conversion motor adopts the frequency conversion control skill speed regulation, is a professional grade product, has a long service life, and the manufacturer supplies one year free replacement. In the future, the motor can be maintained by changing the high speed bearing, and the brushed AC motor has a service life of about 300. The motor or motor carbon brush has to be changed in an hour, so the carbon brush AC motor is not guaranteed for one day.
