Product Overview
The TC-1675 is a high-speed, large-format CNC drilling and tapping centre intended for precise machining of large plates, panels and multi-hole components. Optimised for mass tapping, multi-face drilling and micro-drilling of aluminium and non-ferrous alloys, it delivers high productivity with burr-free holes and high-speed tapping.

Main facts

• Table size (bench): 1700×650 mm
• Triaxial stroke (X / Y / Z): 1800 / 750 / 400 mm (note: the specifications table on the page lists 1600/750/400 mm in one row)
• Maximum carrying capacity: 500 kg
• Spindle speed: 20,000 rpm

Key Features

• Extra-large working area: 1700×650 mm bench accommodates long panels, plates and mould bases without repositioning.
• Extended X travel (1800 mm option): supports full-length part processing in one pass to reduce fixture cost and machining time.
• High-speed spindle (20,000 rpm): ensures clean tapping and burr-free micro-drilling in aluminium and magnesium alloys.
• Fast tool change and precision positioning: improves cycle time for multi-hole drilling and thread-cutting operations.
• Heavy load handling (500 kg): suitable for thick plates and large mould fixtures.

Recommended Configurations

• High-speed servo ATC (automatic tool changer) — reduces cycle time for multi-tool operations.
• Mist collection system — improves operator environment and chip evacuation.
• Through-spindle coolant — essential for deep-hole tapping and long-drill applications.
• Auto pallet changer (APC) — increases productivity for batch production.
• CCD positioning system — for fixture verification and part orientation auto-correction.

Application Case

• Client: 5G aluminium enclosure supplier (China).
• Workpiece: thin-wall aluminium housings with approximately 70 threaded holes.
• Setup: TC-1675 with 20-tool servo ATC and through-spindle coolant.
• Results: thread pitch deviation < ±0.01 mm; cycle time < 80 s per housing; hole roundness deviation < 5 μm; reported zero thread defects under high-speed tapping cycles.
