Sapphire, jade, and emerald, among other stones, are subject to risk at every step from mining and cutting to processing and polishing. From raw stone to finished product, the process generally involves material selection, cutting, design, rough carving, fine carving, and polishing. Cutting is one of the initial processing steps for raw stones. Single-wire cutting equipment is mainly used for squaring hard and brittle materials such as jade, emerald, and magnetic materials. It uses a diamond wire containing diamond particles to reciprocate at high speed, thereby cutting the material in the processing area, turning large pieces into smaller ones to facilitate subsequent processing and production.
To meet the needs of industry development, ZhengXin Electric has launched a high-speed, stable, powerful and precise single-wire jade cutting equipment solution, which effectively improves the automation level of the jade cutting control system and promotes the iterative upgrading of jade cutting technology.
Scheme Composition
Sine Electric's jade single-wire cutting equipment solution uses the Sine Electric EA300E series EtherCAT control scheme, which consists of a motion controller, servo system, encoder, etc. It can accurately control the high-speed operation of the cutting equipment, making the cutting surface flat and smooth while effectively shortening the cutting time, meeting the requirements of high speed, high precision and high efficiency.
Scheme Composition
Controller: Including HMI and motion control system, it is the core of the entire system, mainly responsible for data calculation and processing, display of various statuses, and parameter setting;
Servo system: A crucial component of the entire solution. It is responsible for executing electronic gear commands, completing corresponding actions quickly and accurately, and requires high responsiveness and stability.
Encoder: Periodic calculation of the diameter of the take-up and take-down rollers.
Software Interface
The efficient algorithm, combined with the cutting scene and cutting process, automatically and accurately calculates the running trajectory at each position, achieving fine process control.
Main processes
1. Servo-controlled wire feeding is used, and the wire feeding command speed is derived based on the automatically calculated wire roll diameter and the set cutting speed;
2. Two lifting servos are coupled to a virtual axis via gears. The virtual axis then moves downward by a feed rate, and the up-and-down swing function is achieved by superimposing commands.
3. The rocker arm shaft applies a constant tension to the cable through torque control;
4. Servo winding is used, and the winding command speed is obtained based on the automatically calculated winding diameter and PID.
Solution advantages
01. Dual lifting and smooth speed-changing oscillation maintains a smooth cut surface.
02. No warm-up required; simply plug in power to start high-speed cutting.
03. No spindle tension control, saving on electrical mechanism costs.
04. High-speed tension control, tension 15-60N, tension lever fluctuation ±0.5
05. PID parameter self-tuning
Application scenarios
Zhengxian Electric will continue to keep up with market demands, leverage its automation platform and in-depth understanding of industry processes, increase R&D investment, and provide more professional system solutions for various industries to help customers achieve comprehensive improvements in production efficiency and corporate benefits!
