Description
I. Key Features & Highlights
Quad Independent Spindles Delivering 4x Throughput for Thick & Hard Materials
Engineered for commercial sign factories and industrial fabricators, the YH1325 4-Head Independent CNC Router features four fully independent Z-axis assemblies. Unlike linked multi-spindle routers, each head operates on its own dedicated servo drive, allowing high-speed batch output without mechanical cross-talk or vibration.
- 4 True Independent Z-Axis Heads: Each spindle is mounted on an individual Z-axis carriage powered by a Leadshine HBS758S closed-loop hybrid servo, enabling individual height adjustments, individual tool setting, and the flexibility to park unused heads.
- 12KW Total Spindle Cutting Force: Four 3.0KW heavy-duty water-cooled spindles provide immense aggregate power to plunge effortlessly through dense hardwood, thick acrylic, and composite boards simultaneously.
- Dedicated Cooling & Calibration Circuits: Includes four individual 75W multi-functional submersible pumps (3,500 L/h, 3.5m head) to guarantee isolated thermal stability, along with four dedicated auto-tool calibrators.
- Automated Electric Lubrication: Upgraded electric metering oil pump delivers programmed lubrication cycles to all guideways, minimizing wear during intensive industrial batch production.

IV. Applications & Processed Materials
High-Output Batch Production of Thick Acrylic Signs & Heavy Wood Reliefs
Specially designed for manufacturing plants that produce hard, thick advertising components and carved furniture parts in multi-piece runs:
- Multi-Set Thick Acrylic Letters: Simultaneously cuts four identical sets of 20–30mm thick crystal-clear acrylic channel letters, brand emblems, and flame-polished signage elements.
- Deep Relief Woodworking & Carved Panels: Heavy carving of four identical hardwood art plaques, 3D relief furniture doors, luxury decorative panels, and architectural corbels.
- Volume Retail Display Production: Parallel batch grooving, slotting, and profiling of heavy-duty PVC boards and dense MDF side uprights for commercial retail gondolas.
V. Frequently Asked Questions (FAQ)
Q1: What is the key operational advantage of “independent heads” over connected multi-spindles?
A: Independent heads are each driven by their own Z-axis motor. This allows precise independent tool length calibration for each spindle, individual depth offsets, and the ability to park heads out of the way when routing wider parts with 1, 2, or 3 heads.
Q2: Can all four spindles cut through 20–30mm thick acrylic sheets simultaneously?
A: Yes. Powered by four heavy-duty 3.0KW spindles (12KW total) and closed-loop hybrid servo drives, the machine delivers high torque to slice through thick acrylic, dense hardwood, and thick PVC without bogging down or losing steps.
Q3: How are the four spindles effectively cooled during extended production runs?
A: The system includes four separate high-flow 75W submersible water pumps (3,500 L/h each), isolating each spindle’s cooling loop to prevent heat buildup and ensure continuous thermal stability.
Q4: What is the delivery lead time for this machine?
A: Lead times depend on specific custom requirements (electrical voltages, spindle power configurations, tool sets), workshop assembly loads, comprehensive quality testing, and international shipping arrangements. Exact dispatch schedules will be provided upon formal configuration review.
Andrzej Kowalski 🇵🇱 (Warsaw, Poland) –
We bought the 4-head independent YH1325 for our sign factory, and it’s transformed our production. Four independent 3kW water-cooled spindles running simultaneously—we’re producing four times the output compared to our old single-spindle machine. The individual Z-axis control is a huge advantage; we can park unused heads when running smaller jobs. The closed-loop servo drives are accurate and the machine is rock-solid even at 15m/min. We’ve been running it 8 hours a day for two months now, cutting acrylic letters and PVC signs. Excellent investment for any production shop!
Alex_Zhang –
Dzień dobry Andrzej! Thank you for the detailed review. The 4-head independent configuration is indeed designed for production shops like yours—four heads, four times the throughput. We’re glad the closed-loop servo drives and individual Z-axis control are delivering the accuracy and flexibility you need. Two months of daily 8-hour runs is a great testament to the machine’s reliability. Keep up the great production!
