Woodworking engraving machine manufacturer in 2022Thorpe
The woodworking engraving machine must be damaged when it is in use, let’s see how to solve it first. If the spindle motor of the woodworking engraving machine heats up, be sure to pay attention. If it is not dealt with early, it will affect the lubrication and service life of the spindle bearing of the machine tool, and also affect the use of the entire spindle.
The internal structure of a stepping motor consists of an iron core and winding coils. Coils have resistance, and energization will cause losses. Losses are proportional to the square of resistance and current. This is copper loss. If the current is not a standard DC or sine wave, harmonic losses are also formed; and the iron core has a hysteretic eddy current effect. Losses are also formed in the alternating magnetic field, the magnitude of which is related to material, current, frequency, voltage, etc.
Both copper and iron losses come in the form of thermal energy, which affects the efficiency of the motor. Stepper motors generally pursue positioning accuracy and torque output. The efficiency is low, the current is usually large, and the harmonic content is high. The frequency of the current AC inverter also changes with the change of the speed, so the heating phenomenon of the stepper motor is more common, which is more common than the general AC. Serious motor.
Whether the heating range of the motor is reasonable and can make the motor heat up:
First, look at the insulation level inside the woodworking engraving machine motor. At high temperature (above 130 degrees), the insulating properties of the internal structure will be destroyed. So as long as the internal structure does not exceed 130 degrees, the motor will not be damaged, and the external temperature is lower than 90 degrees at this time. Therefore, the surface temperature of the stepper motor is normal at 70~80℃. An easy way to measure temperature is: a thermometer.
Scope of application of woodworking engraving machine:
Wooden doors and furniture decoration industry: solid wood composite doors, cabinet doors, large-area board plane carving, solid wood carving, panel furniture carving, antique mahogany furniture carving, solid wood art mural carving and other industries.
Wooden handicraft processing: clock stands, craft photo frames, calligraphy cards, electrical countertops, sports equipment, thin aluminum plate carving.
Features of woodworking engraving machine:
Optional linear square guide rails and double-row and four-row ball sliders have large bearing capacity, stable operation, high precision and durability. The ball screw has high precision and the lower knife is accurate.
The main shaft adopts the high-speed water-cooled motor of Japan NSK bearing. 6KW air-cooled spindle 4.5KW spindle, high power and stable performance.
The handle-type control system adopts intelligent budget rules to give full play to the potential of the motor and realize high-speed processing. The curve is synchronized with the line, and the curve is more beautiful.
Good software compatibility, compatible with various CAD/CAM design and production software such as type3/Artcam/Castmate/Wentai.
High-speed drive stepper motor and driver are adopted, and the Y-axis is driven by dual motors, so that the high-speed operation can reach an idle speed of more than 25m/min. With high-power cutting spindle, the engraving speed is faster.
