Weicheng offers the PCD PCB Cutting and Milling Tool for PCB manufacturers looking to combine panel cutting and edge milling in one operation. Featuring a front-cutting-tooth and rear-fine-milling-tooth structure, this integrated cutter separates connected panels and removes residual edge burrs in a single pass. Compared with traditional processes using separate cutting blades and milling cutters, it reduces the need for two independent working stations and spindle fixtures, minimizes board transfers between operations, and helps improve overall production-line efficiency.
● Integrated Cutting and Milling: The front teeth cut connected PCB panels, while the rear teeth synchronously remove residual burrs. Both operations are completed in one pass without requiring a separate milling process.
● Reduced Equipment Requirements: The integrated structure reduces the need for one set of spindle fixtures and two independent processing stations.
● Fewer Board Transfers: Completing cutting and edge milling in one operation avoids transferring boards between separate stations, helping reduce the risk of surface scratches during handling.
● Improved Production Efficiency: Combining two processing steps helps shorten the overall production cycle and improve production-line throughput.
● Wear-Resistant PCD Segments: High-hardness PCD cutting segments provide wear resistance for PCB cutting and milling operations.
● Flexible Customization: Outer diameter, inner hole, tooth-height step and tooth profile can be customized to match different depaneling machine configurations.
The PCD PCB Cutting and Milling Tool adopts a double-step tooth structure. Its front cutting teeth perform the primary panel-cutting operation, while the rear fine-milling teeth synchronously process the newly cut edges.
● Front Cutting: The front teeth cut through the connected PCB panels according to the selected tool dimensions and step configuration.
● Rear Fine Milling: The rear teeth remove residual burrs and edge material during the same pass, reducing the need for a separate milling operation.
● Integrated Processing: Cutting and fine milling are completed in one operation. This helps eliminate additional board transfers between independent working stations and simplifies the processing sequence.
The tooth-step height must be matched to the actual PCB thickness. Appropriate step selection helps prevent incomplete cutting and supports the required processing result.
The cutting teeth use high-hardness polycrystalline diamond (PCD) segments. These segments provide wear resistance for repeated cutting and fine-milling operations.
The cutter uses an SKS51 substrate. PCD segments are bonded to the substrate through a high-temperature composite pressing process. The bonding structure is designed to maintain segment attachment during high-speed cutting and prevent internal cracks.
The front cutting teeth and rear fine-milling teeth are arranged in a double-step structure. Their dimensions and relative positions determine the cutting and finishing sequence. Tooth-step height should be selected according to the PCB thickness and actual processing requirements.
| Ordinal | Outer Diameter ØD (mm) | Thickness B (mm) | Inner Diameter Ød (mm) | Teeth Number Z | Step H (mm) |
| 01 | 120 | 2.0 | 25.4 | 30 | 0.4 |
| 02 | 120 | 3.2 | 32 | 30 | 0.9 |
| 03 | 140 | 3.0 | 25.4 | 30 | 0.4 / 0.6 / 1.0 |
| 04 | 150 | 3.0 | 25.4 | 36 | 0.2 / 0.4 / 0.9 / 1.0 / 1.8 |
| 05 | 160 | 4.0 | 25.4 | 40 | 0.4 / 0.6 / 1.0 |
| 06 | 300 | 3.0 | 32 | 72 | 0.9 |
Parameter Note: Tooth-step height must be customized or selected according to the actual PCB thickness to prevent incomplete cutting.
● For PCB Thickness ≤1.0 mm: Select a small step height of 0.2–0.5 mm according to the actual board structure and processing requirements to help prevent excessive penetration into the core layer.
● For Non-Standard Machines: Confirm the spindle and fixture dimensions before selecting the outer diameter and bore size. Custom dimensions can be specified according to machine drawings.
● For Different Cutting Requirements: Select the tooth-step height according to the actual PCB thickness. The PCD PCB Cutting and Milling Tool should be matched to the required cutting depth to help prevent incomplete cutting.
| Comparison Item | Separate Tungsten-Steel Blade and Milling Cutter | Weicheng Integrated PCD Cutting-Milling Cutter |
| Working Stations | Two independent stations | Single-station, one-pass processing |
| Production Cycle | Longer processing cycle | Shorter processing cycle |
| Tool Replacement Frequency | Frequent | Lower replacement frequency according to supplied product comparison data |
| Edge Burr | May leave visible fiber residues | Rear milling teeth remove residual burrs during the same pass |
| Overall Comprehensive Cost | Higher combined labor and tool expenses | Potentially lower long-term processing costs |
Comparison Note: Actual processing efficiency, tool replacement frequency and overall costs depend on PCB material, machine conditions, processing parameters and maintenance practices.
