High-Density 8-Row CNC Boring Machine for Structural Drilling (Model HD-8242BC)

Solve the challenge of complex “bottom-heavy” drilling patterns. The HD-8242BC is designed for manufacturers who need to process furniture parts requiring extensive joinery on the underside, such as invisible connectors and structural dowels.

Unlike standard machines that offer balanced top/bottom drilling, this unit is a Bottom-Processing Specialist. It features an aggressive configuration that maximizes drilling capacity on the bottom face, allowing you to complete intricate wardrobe partitions and heavy-duty shelving in a single pass without flipping the board.

 Why Choose a “Bottom-Focused” Configuration?

1. Specialized 4-Bottom Row Layout

The defining feature of the HD-8242BC is its asymmetric drill block arrangement. By equipping the machine with 4 Bottom Rows (double the industry standard) versus 2 Top Rows, we have created a solution specifically for hidden joinery.

• The Benefit: It eliminates the bottleneck often caused by insufficient bottom drills when processing complex cabinets that demand clean, invisible exterior surfaces.

2. High-Density Pattern Capability

While we won’t bore you with just numbers, the sheer volume of spindles on this 8-row machine allows for extreme versatility. You can keep a wide array of drill bit diameters (e.g., 5mm, 8mm, 10mm, 15mm) installed simultaneously.

• The Result: Zero setup time between different board types. Whether you are drilling cam locks or wooden dowels, the tool is already there, ready to fire.

3. Deep Structural Boring

This machine is built for strength. Capable of a maximum boring depth of 60mm, it is superior to high-speed thin-board machines. This makes it the ideal choice for solid wood components or thick composite panels that require deep, structural dowel insertion for maximum load-bearing capacity.

4. Stable Industrial Performance

Efficiency meets stability. With a robust net weight of 3500kg and a total power of 21kW, the HD-8242BC delivers consistent precision at a pace of 8-15 pieces per minute. It is engineered for factories that prioritize pattern complexity and hole quality over simple throughput.

Technical Specifications

Ideal Applications

• Custom Wardrobes: Where internal partitions require dense shelf holes and connector holes on the bottom face.

• Minimalist Furniture: Designs that use hidden connectors (requiring bottom drilling) to ensure no screw holes are visible on the top surface.

• Structural Components: Thick boards requiring deep (60mm) structural dowel holes.

FAQ: Choosing the Right 8-Row Solution

I see you have two 8-row models (BC and BNC). Which one do I need?

It depends on your product structure:

• Choose the HD-8242BC (This Model) if your furniture design requires more holes on the bottom than on the top (e.g., invisible connections). Its 4-Bottom Row layout is unmatched for this specific task.

• Choose the HD-8242BNC if you need a heavier (6.5T), faster machine for general high-volume production.

Can this machine handle thick boards?

Absolutely. With a max boring depth of 60mm and heavy-duty clamping, it is specifically optimized for structural parts, ensuring verticality and precision even in deep holes.
