Ultrasonic cutting machine Ultrasonic cutting machine is a type of equipment that uses ultrasonic energy for cutting. It is characterized by no cutting edge. In other words, no traditional cutting edge is needed.
Traditional cutting is to use a knife with a sharp edge to press against the material being cut. This pressure is concentrated at the edge of the blade, and the pressure is very large, exceeding the shear strength of the material being cut, and the molecular bond of the material is pulled apart and cut off. Because the material is pulled apart by strong pressure, the cutting edge of the cutting tool should be very sharp, and the material itself must withstand relatively large pressure. The cutting efficiency of soft and elastic materials is not high.
The principle of the ultrasonic cutting machine is completely different. It uses ultrasonic energy to locally heat and melt the material being cut to achieve the purpose of cutting the material. Therefore, ultrasonic cutting does not require a sharp cutting edge or a large amount of pressure, and will not cause chipping or damage of the material being cut.
At the same time, because the cutting blade is doing ultrasonic vibration, the friction resistance is particularly small, and the material to be cut is not easy to stick to the blade. This is particularly effective for viscous and elastic materials, frozen materials, such as food, rubber materials, and objects that are inconvenient to apply pressure. Ultrasonic cutting also has a great advantage, that is, it has fusion at the cutting part while cutting, and the cutting part is perfectly edge-sealed, which will not cause flashing of the textile material.

NICE3000+ Elevator High Performance Integrated Controller
Comprehensive Function Features
Direct-To-Floor
By the principles of distance, automatically generate the smooth curves from start of parking, no crawling and directly stop in the levelling position.
Optimum Velocity Profile Efficiency
The elevator controller will optimise the velocity profile based on the desired travel distance demand instead of floor number.
Advanced Door-Opening
Under the automatic operation state, the speed during stopping is less than 0.1 m/s and the gate signals effective, system shorts door-lock signal through advanced door-opening module and then opens the door ahead of time to enhance the elevator efficiency
Category Door Open Holding Set-Time
System can automatically identify different time to keep the open calls to open the door, instructions to open the door, the door to protect open, delay to open the door and to open the door inaccordance with the setting time.
Re-levelling
This may occur when the lift stops at the floor station, and a large number of persons or goods enter or leaves. The levelling fluctuates because of the elastic deformation of elevator Wire Rope and the rubber. System is allowed to run automatically at the relevelling speed to the levelling station with the door open.
Self-Rescue Levelling
The elevator is in its normal operating state, but doesn`t stop at the correct level. If it meets the safety requirements to run, the lift will automatically run slowly to the nearest floor area, and then open the door.
Emergency Inertia Rescue Mode
Applicable for permanent-magnet synchronous motors only. When there is a power failure, system will short-circuit the motor phases through its contactor and produce a restraining torque when in motion. Based on the elevator inertia, the elevator will slide slowly and controller will open the elevator door when it reaches levelling position.
Emergency Self-Rescue Time-Out Protection
When elevator is at balance load or rescue device power capacity is inadequate. Long rescue time lapse is expected and accident may occur. This function enables the system to self-disable the emergency operation.
Elevator Position Auto Calibration
Each time the elevator enters the terminal floor zone, system will self-calibrate the position counter with respect to the 1st slowdown limit switch so that elevator over travel operation will be eliminated.
Fire Alarm Rescue Function
Enable user to preset the elevator designated homing floor when fireman mode is enabled
