Four-Spindle Thermal Drilling and Tapping Machine

DUOMI CNC Four-Spindle Thermal Drilling and Tapping Machine Installed at Customer Production Facility

A DUOMI CNC four-spindle thermal drilling and tapping machine has recently been installed and commissioned at a customer’s production workshop. Following on-site setup and testing, the machine has officially entered regular production, supporting high-efficiency drilling and tapping operations. This installation represents a practical upgrade of the customer’s existing manufacturing process, focusing on productivity improvement and process stability. Machine Configuration and Processing Concept The installed machine features a four-spindle configuration designed for simultaneous operation. Each spindle performs one drilling operation followed by one tapping operation within the same production cycle. By processing four identical hole positions at the same time, the machine achieves a “one drill, one tap” workflow with significantly improved efficiency compared to single-spindle equipment. This configuration is especially

Practical Advantages of DUOMI CNC as a Source Factory for Drilling and Tapping Machines

Practical Advantages of DUOMI CNC as a Source Factory for Drilling and Tapping Machines

As a direct manufacturer of CNC drilling and tapping machines, DUOMI CNC operates without intermediate layers between design, production, and delivery. This structure brings practical benefits that are often overlooked when equipment is sourced through trading companies or system integrators. Because the machines are built in-house, production schedules, component sourcing, and quality control are managed internally. This allows better coordination when adapting machines for different materials, hole sizes, or tapping requirements. Adjustments are handled at the manufacturing level rather than being passed between multiple suppliers. DUOMI CNC also conducts assembly, alignment, and functional testing in its own facility. Issues related to rigidity, accuracy, or repeatability are identified and resolved before shipment. This reduces the need for on-site corrections after installation.

How We Formed M10 Threads on 3mm Stainless Steel Square Tubes Without Welding

How We Formed M10 Threads on 3mm Stainless Steel Square Tubes Without Welding

Shop Floor Background During a recent production test, we were asked to create M10 threaded connections on stainless steel square tubes without using welded nuts. The tubes were intended for load-bearing industrial frames where both strength and surface appearance were important. Material used was SUS304 stainless steel square tube, 50×50 mm, with a wall thickness of 3 mm. Issues with Traditional Methods When conventional drilling and tapping were used, the effective thread depth was limited by the tube wall thickness. Welding nuts solved the strength issue but added extra labor, heat distortion, and post-weld surface finishing. The customer wanted a cleaner and more efficient solution. Thermal Friction Drilling Setup To address this, a thermal friction drilling and tapping process was

CNC Drilling & Milling Machines Shipped Overseas

From Assembly Line to Global Delivery: DUOMI CNC Drilling & Milling Machines on the Move

The production floor at DUOMI CNC has recently reached another important milestone. A newly completed series of CNC drilling and milling machines has been fully assembled, tested, and prepared for shipment to international customers, marking the final stage of a carefully controlled manufacturing cycle. Rather than focusing only on delivery, this shipment reflects DUOMI CNC’s complete workflow—from engineering design to real-world production readiness. A Shipment That Starts with Engineering, Not Packaging Every DUOMI CNC drilling and milling machine begins with application-oriented design. Machine configurations are planned according to real customer needs such as hole accuracy, milling stability, cycle time, and material compatibility. During production, attention is placed on: Only after the machine meets internal machining standards does it move forward
