Vimfun Diamond Wire Saw-High-Precision Endless Diamond Wire Cutting Solutions for Hard & Brittle Materials

Company Overview

Vimfun Diamond Wire Saw is a technology-driven manufacturer specializing in endless (closed-loop) diamond wire cutting solutions for high-value hard and brittle materials.

We focus on helping customers in optics, semiconductors, advanced ceramics, and carbon materials industries achieve higher cutting stability, better surface quality, and lower material loss, especially when processing large sizes, complex geometries, and high-hardness materials.

Unlike traditional reciprocating wire saws, Vimfun machines utilize continuous one-direction endless diamond wire motion, eliminating direction reversal and significantly improving cutting consistency, surface finish, and wire life.

Core Technology & Competitive Advantages

• Endless Diamond Wire System
  Continuous closed-loop wire motion with no direction switching, reducing vibration and wire marks.

• High Linear Speed up to 80 m/s
  Enables efficient cutting of sapphire, SiC, ceramics, and optical glass while maintaining stability.

• Ultra-Narrow Kerf Width (as small as 0.35 mm)
  Maximizes material utilization and reduces downstream grinding and polishing cost.

• Stable Tension Control System
  Ensures uniform cutting force across the entire cutting path, critical for brittle and high-value materials.

• Flexible Machine Structures
  Gantry, horizontal, vertical, rotary axis, contour cutting, and ultra-large format systems available.

• Customization-Oriented Engineering
  Machines can be configured for slicing, contour cutting, polygon cutting, and special-shape processing.

Typical Customer Applications

Optical & Crystal Materials Processing

• Cutting N-BK7 optical glass blocks into bars or small cubic components with minimal chipping and internal stress.

• Contour cutting of circular germanium (Ge) lenses into customized profiles for AR and infrared optical systems.

• Slicing and polygon cutting (triangular, pentagonal, octagonal, and other shapes) of
  Corning glass, K9 glass, medical glass, and optical glass, ensuring smooth edges and dimensional accuracy.

Large-Size Optical Blanks & Astronomical Applications

• Precision cutting of ultra-large optical glass blanks up to 3 meters in diameter, used for aerospace and astronomical telescope lenses.

• Stable slicing of quartz ingots and sapphire boules, maintaining flatness and surface integrity for subsequent precision processing.
