Transmission System

Z/Y-axis driven by precision-ground ball screws and high-accuracy linear rails. Servo motor and closed-loop stepper drives. Repeat positioning accuracy ±0.01 mm. Counterweight tensioning maintains constant force on 0.33–0.45 mm diamond wire. Imported pulley bearings for long-term rotational precision.

Control System

X80 touchscreen interface stores cutting parameters. Power-off protection resumes interrupted cuts. Electronic handwheel for manual positioning. Input AC220V 50–60 Hz, 2 kW. Supports mouse/keyboard for programming complex paths.

Cutting Unit

Five programmable modes: vertical, rotary, angle (360° B-axis), profile, and pendulum cutting. Pendulum oscillation eliminates center point for faster processing of hard materials. Quick-change worktable (10 sec) minimizes downtime. Cutting accuracy ±0.05 mm, surface roughness ≤0.05 mm.

Advantages &Features

Pendulum oscillation cutting eliminates the center point, enabling faster processing of hard, brittle materials while preventing edge chipping—boosting throughput and improving yield on expensive workpieces.

10-second quick-change worktable minimizes downtime between jobs, maximizing machine utilization for high-mix, low-volume production runs.

Precision-ground ball screws and linear guides deliver ±0.01 mm repeatability, ensuring consistent part quality and eliminating secondary finishing operations.

0.33–0.45 mm diamond wire creates an ultranarrow kerf, reducing material loss by up to 30%—direct savings when slicing costly ceramics, crystals, or semiconductors.

Intuitive touchscreen interface stores up to 60 cutting recipes, reducing setup errors and operator training time while maintaining process repeatability.

Fully enclosed machining chamber suppresses dust and noise, enabling dry, coolantfree operation—creating a cleaner, safer workplace and lowering disposal costs.

Five programmable cutting modes (vertical, rotary, angle, profile, pendulum) replace multiple dedicated machines, cutting capital expenditure and floor space requirements.

Automatic lubrication supplies oil to ball screws and guides, reducing wear and preserving positioning accuracy with minimal maintenance.

Integrated LED lighting inside the machining chamber provides clear visibility of the cutting zone, enabling real-time inspection without opening the enclosure or stopping the process.

FAQ

What is the process of wafer slicing?

Wafer slicing converts silicon ingots into thin wafers using a wire saw. The ingot is mounted and pressed against a wire web moving at high speed. Diamond abrasive or slurry removes material gradually. After slicing, wafers undergo cleaning, lapping to remove damage, and polishing to achieve mirror-like surfaces for device fabrication .

What is the best tool to cut Silicon Ingot?

Endless diamond wire saw is considered the best tool for silicon ingot cutting. Compared to band saws, it offers lower edge chipping, superior surface quality, and reduced material wastage . It handles ingots up to 18 inches with ±0.02-0.03 mm repeatability. Some manufacturers also offer electroplated band saws for specific applications .

How a silicon wafer & ingot wire saw cutting machine works?

The machine uses an endless diamond wire loop running continuously between guide rollers . The ingot mounts on a programmable feeder that moves vertically against the wire web. Servo motors control feed rates while coolant removes debris. Multi-axis control enables both slicing and complex shape cutting with ±0.02 mm precision .

How much does silicon wafer & ingot wire saw cutting machine cost?

Commercial silicon ingot cutting machines typically range from $30,000 to $90,000 depending on capacity and features . A production-grade 18-inch silicon ingot cutter with automation starts around $30,000+, while high-precision research models with advanced controls exceed $80,000. Price varies by ingot diameter, automation level, and precision requirements .

What is silicon wafer & ingot wire saw cutting machine?

It’s a precision machine tool for semiconductor and photovoltaic industries to cut silicon ingots into wafers and perform cropping/seeding operations . Using endless diamond wire technology, it achieves ±0.02-0.05 mm accuracy with minimal kerf loss, handling ingots up to 18 inches in diameter for applications like top/tail cut, bridging, and seeding .

What is the lifespan of a silicon wafer & ingot wire saw cutting machine?

The machine typically lasts 10-15 years with proper maintenance. Diamond wire life depends on cutting parameters—high-performance wire achieves 250-500 cm²/m cutting area before replacement . Optimized wire management systems minimize non-cutting wear, significantly extending wire life. Wire accounts for approximately 9% of wafer production costs .
