High-Precision Multi-Wire Cutting Equipment for Mass Production
of Sapphire Materials
The multi-wire cutting machine is a specialized device that
utilizes high-speed reciprocating metal wires to carry diamond
abrasives, enabling large-volume, high-precision slicing of
hard and brittle materials. Specifically designed for sapphire—a
material characterized by high hardness (Mohs hardness up to 8.5)
and high brittleness—multi-wire cutting technology has become the
core process for preparing sapphire wafers and substrates. It
effectively addresses the limitations of traditional cutting
methods, such as low efficiency, high material loss, and poor
surface quality.
Multi-wire Cutting Machine Working Principle
During operation, extremely fine diamond wires are tensioned
under precise control and guided by a system of rollers to form a
large "wire web." The sapphire ingot is driven by a worktable and
fed into this web. Through the high-speed movement of the wires,
abrasives (typically diamond) are carried into the cutting zone to
grind the sapphire, allowing the entire ingot to be sliced into
hundreds or even thousands of thin sheets simultaneously in a
single pass. Advanced equipment incorporates a swinging motion,
which reduces the contact length between the wire and the
workpiece, thereby enhancing cutting stability and minimizing
cutting forces.
Multi-wire Cutting Machine Characteristics & Advantages
Compared to traditional processes like inner-diameter blade
cutting, multi-wire cutting equipment offers significant advantages
for processing sapphire, as summarized in the table below:
Characteristic/Advantage
| Specific Manifestation
|
| High Efficiency | A single feed can produce hundreds of sapphire wafers
simultaneously, far exceeding the efficiency of traditional
methods that cut only one slice at a time.
|
| High Precision and Excellent Surface Quality | Capable of achieving micron-level thickness control and very
low surface roughness (Ra can reach 0.3 μm), significantly
improving product yield.
|
| Low Material Loss | The use of extremely fine cutting wires (as thin as a hair) results
in very narrow kerfs, greatly reducing the loss of expensive
sapphire material.
|
| High Automation and Stability | Employs CNC systems for precise closed-loop control of parameters
like tension and speed, ensuring a stable and reliable processing
operation.
|
| Continuous Technological Progress | Domestic equipment has achieved breakthroughs in core technologies
like tension control and motor synchronization, offering high
cost-effectiveness and gradually replacing imported machines.
