1. The characteristics of precision machining spindles are low noise, high speed, and high height, making them suitable for processing particularly precise workpieces such as seals, nameplates, badges, gifts, etc. This type of motor is usually a high-speed variable frequency motor with low power, typically below 1500W. The defect is that the ability to cut thick materials is poor, and it is not suitable for cutting thick materials. 2. High power cutting spindle is mainly used for cutting and high-power carving. Its characteristic is that it has high power and strong cutting ability, especially suitable for cutting jade and three plane characters. Of course, it can also be used to manufacture badges, nameplates, seals, etc High power cutting spindle, mainly used for cutting and high-power engraving, with the characteristic of high power and strong cutting ability, especially suitable for cutting jade and three plane characters. Of course, it can also manufacture badges, nameplates, seals, etc. This type of high-power spindle can be generally divided into brushless frequency high-speed AC motor and brushed AC motor based on the characteristics of the motor. The main difference is that: A. Brushless frequency conversion motor has a high speed, with a speed range of 700-60000 revolutions per minute, while ordinary brushed AC motor has a maximum speed of no more than 24000 revolutions per minute; B、 Brushless variable frequency motors have high rotational accuracy, minimal wear, low noise, and significantly lower operating noise compared to brushed AC motors; C、 Brushless frequency conversion motors have good stalling characteristics. Due to the special current limiting circuit on the frequency converter, short-term stalling will not burn out the motor, while brushed AC motors will quickly smoke and burn out during overload operation or stalling, and cannot be repaired; D、 Brushless variable frequency motors use variable frequency control technology for speed regulation, and are professional grade products with a long service life. The manufacturer provides a one-year free replacement, and in the future, the motor can be stopped and maintained by replacing the high-speed bearings. However, brushed AC motors need to replace the motor or motor carbon brush due to the approximately 300 hour service life of the electric cable, so carbon brush AC motors are usually not covered by a one-day warranty. 3. The rotation speed of the electronic shaft ranges from 18000 rpm to 160000 rpm, and the most commonly used electronic shafts in the industry today are 18000 rpm and 24000 rpm. Transmission mode: There are two types: screw drive and rack and pinion drive. Overall, the screw has high precision but slow speed, while the gear rack has fast speed but low precision. Control system: There are machining codes available for various CAD/CAM design software such as Weihong/TPYE3/Artam/Castmate/Wentai/DSP. There are also DSP controllers that can be plugged into USB drives for control. The most commonly used one is the Weihong control system. The customer requests to upgrade to a DSP controller, which can be upgraded with an additional fee. The DSP controller is a Beijing Ruizhi Tianhong black card, and the black card driver: the driver is located in the main control box (MAIN  Controller) -->Driver -->throughout the entire control process; Replace the middle section of the motor. His main function is to receive signals from the main control box (NC; CARD), then stop processing the signals and transfer them to the motor and related sensors (SENSOR), and reflect the working condition of the motor to the main control box (MAIN; CONTROLLER)。 Motor: There are usually stepper motors and servo motors. Servo motors are commonly paired with high-end models. Guide rail: There are circular guide rails and linear rectangular guide rails (square rails). Square rails are more expensive than compasses and have stronger accuracy and stability. Some customers will be equipped with XY axis square rails and Z-axis circular rails. Due to the large processing range of XY axis, Z-axis only needs to be moved upwards, resulting in a short stroke. Variable frequency drive: The function of a variable frequency drive is to use the on-off function of power semiconductor devices to convert the power frequency power supply into electrical energy of another frequency for control and installation. The brands we use: Shanghai Jiuchuan/Sifang/Delta. Pump: There is no pump on ordinary advertising machines, but there are pumps available on woodworking and general-purpose models. Pumps include water pumps and non oil pumps. The price of non oil pumps is high and can be optionally selected. Vacuum installation: Advertising machines do not have vacuum cleaners, while carpenters have vacuum installations. In addition, there are two types of countertops: T-shaped groove aluminum frame and vacuum adsorption countertop.
