G104XVN01.0 as a Solution for Wire-Cut EDM Machines

Published on:2024-10-09 | Writer:august | Vivews:

The medium-speed wire-cut electric discharge machine (WEDM) is an advanced type of electric discharge machining (EDM) equipment widely used in metal processing. Its history, principles, and applications are as follows:

History: The development of the medium-speed WEDM can be traced back to a unique technological evolution in China. Initially, it evolved from imported slow-speed WEDMs. After several decades of development, a distinctive medium-speed WEDM technology was formed. This technology has a history of about 40 years, with production mainly concentrated in three regions: Suzhou, Beijing, and Taizhou. The origin of the medium-speed WEDM was to meet user needs by preserving the simple structure, low cost, good process effect, and low consumption of fast-speed WEDMs while introducing advanced concepts from international precision mold processing equipment and multiple cutting techniques of slow-speed WEDMs.

Principles: The working principle of the medium-speed WEDM involves using a continuously moving molybdenum wire (called the electrode wire) as an electrode to perform pulse spark erosion on the workpiece, thereby achieving cutting and shaping. Specifically, the medium-speed WEDM maintains a certain discharge gap between the workpiece and the electrode wire, sprays working fluid, and uses the sparks generated between the electrodes to erode a specific gap. Continuous pulse discharges cut out the required shape and dimensions. During rough machining, high-speed (8-12m/s) wire movement is used, and during finish machining, low-speed (1-3m/s) wire movement is employed. This reduces material deformation and molybdenum wire wear, improving machining quality.

Applications: The primary roles of the medium-speed WEDM include:

  1. High-precision Machining: The medium-speed WEDM is capable of high-precision machining, making it suitable for the precise machining of molds and components.
  2. Multiple Cutting Functionality: By reducing material deformation and molybdenum wire wear, it improves machining quality, offering a compromise between high-speed and low-speed WEDMs.
  3. Stripe-free Cutting: It can achieve stripe-free cutting and multiple cuts, resulting in better machining quality than ordinary high-speed WEDMs.
  4. Wide Application: It is extensively used in the motor core mold industry, mold manufacturing, and precision parts processing, enhancing production efficiency and machining quality.

Technical Development: The technical development of the medium-speed WEDM can be traced back to the 1980s when the high-speed WEDM, a technology independently developed in China, became a milestone in the field of mechanical processing. Since its successful development at the end of the 1960s, after 30 years of continuous improvement and development, high-speed WEDM technology has become an indispensable processing method in manufacturing. In the 1990s, the medium-speed WEDM technology began to develop. In 1993, Trelleborg Company pioneered the medium-speed WEDM and established Shenzhen Foster Company, operating through OEM. Their technological advantages and management model had a profound impact on the Guangdong WEDM market. In 1998, micrometer-level medium-speed WEDM technology was introduced in Toronto, Canada, and in 2006, the world's first micrometer-level medium-speed WEDM was born. In recent years, medium-speed WEDM technology has been derived from fast-speed WEDM machines, adding UV axes to the fast-speed WEDM’s wire frame to achieve four-axis linkage. The wire feeding mechanism is similar to that of fast-speed WEDM, using reciprocating wire feeding, and the control method is similar to that of slow-speed WEDM, enabling multiple cuts. During rough machining, higher wire speed is used.

What are the specific differences in technical principles and application effects between medium-speed, slow-speed, and high-speed wire-cut electric discharge machines (WEDMs)?

There are some specific differences in technical principles and application effects between medium-speed, slow-speed, and high-speed WEDMs.

Technical Principles:

  • Medium-Speed WEDM: The working principle of the medium-speed WEDM involves a continuously moving molybdenum wire (electrode wire) that rotates around a spool at a certain speed. The workpiece, mounted on the machine's worktable, moves according to a predetermined control path relative to the electrode wire. One pole of the pulse power supply is connected to the workpiece, and the other pole is connected to the electrode wire. A certain discharge gap is maintained between the workpiece and the electrode wire, and working fluid is sprayed to facilitate spark erosion and metal removal.
  • Slow-Speed WEDM: Slow-speed WEDM uses a continuously moving fine metal wire (electrode wire) as an electrode to perform pulse spark erosion and cutting on the workpiece.
  • High-Speed WEDM: High-speed WEDM uses high-speed wire movement during rough machining and low-speed wire movement during finish machining.

Application Effects:

  • Medium-Speed WEDM: Combining the advantages of both fast and slow-speed WEDMs, it offers high machining efficiency and lower manufacturing costs, making it suitable for precision mold processing. It has higher flexibility and adaptability by adjusting the wire speed to meet different machining needs.
  • Slow-Speed WEDM: Known for its high efficiency and precision, it is suitable for processing complex and finely detailed parts. The maximum machining rate exceeds 3500 mm²/min, with an effective machining efficiency of 120-150 mm²/min, and the best surface roughness is Ra0.5-0.8 μm, with a cutting accuracy of ±0.005 mm.
  • High-Speed WEDM: Through multiple cutting techniques, it can improve surface quality and machining accuracy.

Advantages and Limitations of Medium-Speed WEDM in Precision Mold Machining:

Advantages:

  1. High Precision and Stability: Medium-speed WEDM machines use precision linear guides, servo drives, and automatic wire threading, enhancing machining precision and stability. These technologies allow the machine to meet high surface finish and roughness requirements in mold manufacturing.
  2. Cost-Effectiveness: Positioned between fast and slow-speed WEDMs, medium-speed WEDM machines offer high precision at a moderate cost, making them widely used in mold manufacturing and precision part processing. Additionally, their simple structure, low cost, good process effect, and low consumption make them highly cost-effective.
  3. Wide Applicability: Despite some limitations, medium-speed WEDM machines are suitable for the production of general parts and ordinary molds. Some models also feature flexible worktable travel and high cutting angles, enabling the processing of different thicknesses and shapes of workpieces.
  4. Intelligent and Automated Upgrades: Future developments in medium-speed WEDM technology will focus on intelligent and automated upgrades, integrating advanced CNC control systems, smart diagnostics and compensation algorithms, and automated loading, unloading, online inspection, and maintenance systems to significantly improve production efficiency and reduce labor costs.

Limitations:

  1. Technical Metrics Gap: Compared to slow-speed WEDM machines, medium-speed WEDM machines have a gap in key technical metrics such as machining precision, surface roughness, and average productivity. This limits their application in certain high-precision mold machining processes.
  2. Limited Application Scope: While widely used in mold manufacturing, medium-speed WEDM machines still have a limited application scope, primarily suitable for the production of general parts and ordinary molds.
  3. Maintenance and Lifespan Issues: Due to the presence of dust in the air, the lead screws of medium-speed WEDM machines may suffer wear, affecting the machine's lifespan.

How to Optimize Multiple Cutting Techniques in Medium-Speed WEDM to Improve Machining Efficiency and Quality:

To optimize the multiple cutting techniques in medium-speed WEDM and improve machining efficiency and quality, the following improvements can be made:

  1. Optimize Cutting Parameters:
    • Reasonably select cutting speed and pulse width parameters to improve cutting speed and surface quality.
    • Set appropriate machining parameters, such as cutting current and pulse width, based on the workpiece thickness, material, surface roughness, and precision requirements before implementing multiple cuts.
  2. Adjust Wire Speed:
    • In multiple cutting processes, the wire speed for the first cut can be appropriately reduced. For example, reducing the wire speed from 11 m/s to 4.4 m/s, although it decreases machining efficiency by about 5%, it significantly reduces mechanical wear on guide wheels, bearings, and conductive blocks, and reduces electrode wire vibration, thereby improving the machine's sustained precision.
  3. Precise Positioning:
    • Accurately position the workpiece in the machine's machining position to reduce machining errors and improve machining precision.
  4. Comprehensive Corner Control Strategy:
    • To improve corner cutting precision in medium-speed WEDM, a comprehensive corner control strategy should be adopted.
  5. Application of Multiple Cutting Techniques:
    • Multiple cutting techniques are fundamental for improving the precision and surface quality of slow-speed WEDM. Generally, the first cut forms the shape, the second cut improves precision, and additional cuts enhance surface quality.
  6. Error Analysis and Precision Improvement Methods:
    • Analyzing the errors in medium-speed WEDM machines and seeking methods to improve precision are crucial for enhancing product quality and machining efficiency.
