Throughfeed Drilling Machine Series — NDC402 / NDB402
Product Overview
The NDC402 and NDB402 are high-efficiency throughfeed multi-row drilling machines designed for panel furniture production.
Both models feature a 6-row configuration (4 bottom drilling rows and 2 side drilling rows), capable of performing 4-sided boring in one continuous process, ensuring high precision and productivity in large-scale manufacturing environments.
The NDC402 (PC Control) version is equipped with an intelligent servo control system for automatic positioning, allowing the machine to quickly adjust drilling patterns based on digital hole maps — ideal for automated production lines with frequent design updates.
The NDB402 (Standard Version) maintains the same strong structure and processing capacity but operates through manual mechanical adjustment, making it a cost-effective and durable choice for factories focusing on stable, high-speed output.
