SX150-12YL Double Disc Grinding Machine for Ferrite
Who It's For
This twin-disc grinding equipment serves manufacturers producing sintered ferrite magnetic components, including ferrite rings for motors, sensors and electronic assemblies. Production lines focused on consistent thickness and parallelism across bulk ferrite batches will benefit, especially plants seeking to cut repeated manual clamping steps unique to brittle ferrite material processing.
Core Machining Performance
All precision indicators are tested under continuous ferrite mass production cycles. Minor output fluctuations may arise based on ferrite blank density and forming consistency:
- Parallelism tolerance: 0.01 mm
- Flatness deviation: 0.01 mm
- Thickness deviation across batches: 0.02 mm
- Finished surface roughness: Ra 0.8 μm
Uniform dual-plane geometry eliminates uneven magnetic clearance in finished electronic assemblies, reducing product reject rates during downstream magnetic testing.
Key Hardware Specifications
Spindle & Fine Feed Control
- Main spindle diameter: Φ150 mm
- Vertical travel of grinding head: 130 mm
- Minimum feed resolution: 0.001 mm
The adjustable vertical stroke accommodates custom fixture tooling tailored to fragile ferrite ring blanks, while micro feed settings prevent chipping and edge damage typical of brittle ferrite materials.
Multi-Group Independent Drive System
- Dual spindle motors: 30 kW each
- Pair of feeding drive motors: 1.8 kW each
- Single wheel trimming motor: 0.9 kW
- Full system total installed power: 96 kW
Clarification on power rating: The 96kW total power includes all core mechanical motors plus supporting auxiliary systems for cooling, hydraulic cycling and automated wheel conditioning required for steady ferrite grinding.
Machine Outer Structure
- Overall dimension (Length × Width × Height): 7000 × 5000 × 2400 mm
The oversized reinforced base suppresses vibration that easily causes cracking on low-toughness ferrite workpieces during long production runs.
Core Operational Advantages for Ferrite Processing
1. Simultaneous two-sided grinding completes finishing on both faces of ferrite rings in one fixture setup, avoiding secondary handling that leads to chipping or dimensional shift of fragile ferrite blanks.
2. Separated spindle, feed and trimming drives disperse vibration and heat load, maintaining stable flatness without generating micro-cracks on sintered ferrite surfaces.
3. 0.001mm precise feed tuning allows gentle stock removal matched to ferrite's brittle material property, balancing processing speed and finished part yield rate.
4. Independent wheel trimming drive maintains uniform abrasive wheel profile, ensuring consistent grinding pressure across every ferrite ring in long batch runs.
5. Heavy wide frame requires no special reinforced foundation on standard factory floors, lowering installation investment for ferrite component manufacturing workshops.
Frequently Asked Questions
Q1: What makes this double disc grinder suitable for ferrite magnetic blanks instead of standard metal grinders?
A: The balanced vibration isolation and micro-accurate feed control are calibrated for brittle sintered ferrite. It minimizes mechanical shock and surface cracking that frequently occurs when processing ferrite on general-purpose metal grinding machines.
Q2: Does this unit support continuous mass production of ferrite rings?
A: Yes. The multi-group split power layout avoids single drive overload during nonstop shifts, and automated wheel trimming cycles reduce manual maintenance downtime for ferrite batch production lines.
Q3: How does dual-sided grinding improve ferrite component quality?
A: Single-sided grinding requires flipping ferrite blanks twice, which introduces parallelism errors and risks breakage. Synchronous double-disc processing locks unified thickness and parallelism in one pass, stabilizing magnetic performance for finished motor and sensor ferrite parts.
