Reciprocating Diamond Multi Wire Saw Machines
High-throughput batch slicing systems for NdFeB magnets, silicon ingots, sapphire, and hard brittle materials — from 430 mm to 1,000 mm workpiece capacity
What Is a Reciprocating Multi Wire Saw?
A reciprocating multi wire saw uses a long spool of diamond-coated wire (typically 0.13–0.25 mm in diameter and up to 30,000 m in length) that reciprocates back and forth across precision-ground roller assemblies. Multiple wire segments run in parallel across the rollers, enabling dozens of simultaneous cuts in a single pass — ideal for high-volume wafer slicing and block cutting operations.
This is fundamentally different from an endless diamond wire saw, which uses a short closed-loop wire (typically 1–10 m) running continuously in one direction. While endless wire saws excel at single-piece precision cutting, profile cutting, and low-volume R&D work, reciprocating multi wire saws are designed for industrial batch production where throughput is the priority.
When to Choose a Reciprocating Multi Wire Saw
If your operation requires cutting large volumes of NdFeB magnet blocks, silicon ingots, sapphire boules, or ceramic blanks into uniform thin slices (0.3–25 mm), a reciprocating multi wire saw will deliver significantly higher throughput than single-wire systems.
Vimfun supplies both technology families — endless loop wire saws for precision single-piece cutting and reciprocating multi wire saws for batch production — so we can recommend the right system for your specific material, volume, and tolerance requirements.

Frequently Asked Questions
A multi wire saw uses a long spool of diamond wire (up to 30,000 m) that reciprocates across multiple rollers, making many simultaneous cuts per cycle. An endless loop wire saw uses a short closed-loop wire running continuously in one direction. Multi wire saws are for batch production; endless wire saws for precision single-piece work.
NdFeB magnets, SmCo magnets, ferrite, silicon, sapphire, advanced ceramics (alumina, zirconia, SiC), quartz, crystal, molybdenum, gold, marble, and various alloys.
QY-430DB and QYGS-600D: down to 0.3 mm. QYGS-430ZB: down to 0.5 mm. Larger models handle 1.5 mm and up.
Combines inverted (top-down) orientation with a rocking worktable. The oscillation reduces contact area, lowering cutting force and improving speed by 30%+. Can be toggled on/off during operation.
Yes. QYZS-750SZ and QY1000-SZ are direct ID saw replacements with narrower kerf (0.13 mm wire vs 0.5-1.0 mm blade), higher material utilization, and better surface quality.
