CNC Drilling Tapping Machine
Product Overview
The [Brand Name] DT Series CNC Drilling Tapping Machine is engineered for high-speed, high-precision machining of small-to-medium metal parts. Built on a ribbed Meehanite cast iron bed with finite element analysis (FEA) optimization, the machine minimizes thermal distortion and absorbs high-frequency cutting vibration during aggressive milling and rapid drilling cycles.
Equipped with a direct-drive BT30 spindle and a high-speed servo tool changer, the DT series reduces non-cutting time to a minimum. It serves high-efficiency production lines in automotive, 3C electronics, and general precision engineering sectors where cycle time directly dictates manufacturing cost.

Key Features
Direct-Drive High-Speed Spindle: Features a 12,000 RPM direct-drive spindle coupled with precision ceramic bearings. This setup eliminates belt-slip power loss, reduces thermal growth during long runs, and achieves dynamic balancing within G0.4 standards.
Rigid Tapping Performance: Integrated with high-resolution absolute encoders on the spindle and servo axis synchronization. Supports rigid tapping up to 6,000 RPM, preventing thread pitch distortion and tap breakage in blind-hole operations.
High-Dynamic Axis Acceleration: X, Y, and Z axes are driven by pre-tensioned C3-grade precision ball screws and linear roller guides. Delivering a 48 m/min rapid traverse rate and 1.0 G acceleration, idle movement time between features is reduced by up to 25%.
High-Capacity Chip Evacuation: Features a dual-side slanted sheet metal design inside the work enclosure paired with dual screw chip conveyors on both sides of the bed, preventing chip accumulation during continuous aluminum or cast iron machining.
