FANUC Slow WireFANUC Slow Wireα-C400iC Basic Introduction

Since 1975, when FANUC began producing slow wire electrical discharge machines (FANUC WEDM), decades of continuous technological updates have made FANUC one of the world's leading manufacturers of wire EDM machines. FANUC slow wire EDM machines (FANUC WEDM) are renowned in the industry for their high speed, high precision, high reliability, low-cost maintenance, and intelligence. They are widely used in mold making, medical, and super-hard material manufacturing industries, with high market shares in Japan, Europe, the United States, and Southeast Asia.

Manufacturing Technology

Manufacturing Process

The manufacturing process of PCD tools mainly includes two stages:

①Manufacturing of PCD composite sheets: PCD composite sheets are sintered from natural or synthetic diamond powder and a binder (containing metals such as cobalt and nickel) in a certain proportion under high temperature (1000~2000°C) and high pressure (50,000~100,000 atmospheres). During sintering, the addition of the binder forms bonding bridges mainly composed of TiC, SiC, Fe, Co, Ni, etc., between diamond crystals, and the diamond crystals are embedded in the skeleton of the bonding bridges in a covalent bond form. The composite sheets are usually made into fixed-diameter and thickness disks, and the sintered composite sheets require grinding, polishing, and other corresponding physical and chemical treatments.

②Processing of PCD inserts: The processing of PCD inserts mainly includes cutting the composite sheets, welding the inserts, and grinding the edges.

Cutting Process

Due to the high hardness and wear resistance of PCD composite sheets, special processing techniques must be used. The main processing methods for PCD composite sheets include EDM wire cutting, laser processing, ultrasonic processing, and high-pressure water jet. A comparison of their process characteristics is provided.

Comparison of PCD Composite Sheet Cutting Processes:

Process Method - Process Characteristics

EDM - Highly concentrated pulsed discharge energy and strong discharge force melt the metal in the PCD material, partially graphitizing and oxidizing the diamond, and partially causing diamond脱落 (falling off). Good processability and high efficiency.

Ultrasonic Processing - Low processing efficiency, high consumption of diamond micropowder, and significant dust pollution.

Laser Processing - Non-contact processing, high efficiency, small processing deformation, poor processability.

Among the above processing methods, EDM yields the best results. The presence of bonding bridges in PCD makes EDM processing of composite sheets possible. Under the condition of a working fluid, a pulsed voltage is used to form a discharge channel near the electrode metal in the working fluid, generating discharge sparks locally. The instantaneous high temperature can melt and脱落 (cause to fall off) the polycrystalline diamond, forming the required triangular, rectangular, or square insert blank. The efficiency and surface quality of EDM processing of PCD composite sheets are affected by factors such as cutting speed, PCD grain size, layer thickness, and electrode quality. The rational selection of cutting speed is crucial. Experiments show that increasing the cutting speed reduces the processing surface quality, while too low a cutting speed can cause "wire bowing" and reduce cutting efficiency. Increasing the thickness of the PCD insert also reduces the cutting speed.
