Magnetron sputtering machine GFOUR

Product Overview
GFOUR is a high-power pulsed magnetron sputtering coating system designed for industrial tooling and component coating applications. The unit integrates four independent magnetron cathodes with high‑power pulsed outputs and a programmable bias system to adapt ionization and film properties across a wide thickness range (0.5–30 µm). The system targets manufacturers of cutting tools, dies and precision industrial parts requiring controlled surface finish, coating density, hardness and adhesion.

Key Benefits

• Smooth, droplet‑free surfaces with low friction coefficient suitable for fine finishing.
• High wear resistance through optimized hardness, density and coating–substrate adhesion.
• Low residual stress coatings that preserve cutting edge integrity and reduce cracking/peeling.
• Flexible process control: adjustable ionization rate, pulse parameters and bias allow tuning for thin or thick coatings.

GFOUR Features

• Coating thickness range: 0.5–30 µm
• Deposition rate: up to 3 µm/h (process dependent)
• Droplet‑free, low‑friction coatings
• High adhesion between coating and substrate
• High hardness and density with low residual stress
• Process flexibility: ionization rate, discharge pulse, density, stress and thickness adjustable

Application Cases
GFOUR U Series in Milling

• Tool: APMT1135PDER, D17
• Workpiece: Cr12MoV (~48 HRC) (JIS SKD11 / AISI D2)
• Test (end face milling): Vc = 117 m/min; Fz = 0.23 mm/z; ap = 0.1 mm; ae = 12.75 mm; air cooling
• Result: GFOUR‑U2 showed a 70% increase in tool life vs Competitor 1 (HuaSheng Cutting Center)

GFOUR U Series in Heavy‑Duty Milling

• Tools: LNCX1906‑CR3.5; LNCQ190906‑CR5
• Workpiece: C45
• Condition: external gear milling; Vc = 120 m/min; Fn = 90 mm/r; air cooling
• Result: normal wear; tool life ~60% longer vs LM coating (end customer)

GFOUR S Series for Small‑Diameter Tools

• Tool: D1R0.5
• Workpiece: SKD11 (60 HRC)
• Test (face milling): Vc = 56.52 m/min; Fz = 0.022 mm/z; Ap = 0.02 mm; Ae = 0.025 mm; air cooling
• Result: ~33% longer tool life vs competitor BDR at same wear criterion (flank wear > 30 µm)

Technical Feature Display
Coating microstructure and crystal orientation can be tuned via ionization and pulse control to achieve target density and hardness while maintaining a smooth, droplet‑free surface. The process delivers high hardness and density with low residual stress to protect cutting edges and avoid coating failure.
