Danieli automatic threading machine for threading pipes Casing diameter from 1.9 " to 7" can make 96 pipes per hour The machine is new Operating principle: Facing and chamfering on both internal and external diameter Turning and internal and external tapered threading API CSG, LCSG, BCSG, TBG, UTBBG Premium connections FTT Threading Machine - Highlights • Single position tube clamping • High precision CNC control with 3 independent axes • Vibration-free operation • Optimal thread quality • Coolant flow: 100 bar at 150 liters/min FTT Threading Machine – Typical Layout Cutting head Alignment device Clamping system Base frame Feed carriage guiding system Cutting head drag system Radial group drag system Machine base In machined and welded steel frames, unique structure that supports the tube alignment device, the clamping system and the sliding cutting head. Integrated chutes in the work area to collect and convey chips and emulsion to the transport and filtration system. No Vibration Clamping System The pipe clamping consists of 3 fixed sets of hydraulic jaws: 1. Retractable self-centering jaws to pre-align the pipe end axis with the machine's working axis 2. Self-centering jaws to lock the pipe end aligned with the machine's working axis and resist axial forces and torsion No black thread 3. Intermediate clamp consisting of three independent and self-adjusting jaws mounted at 120°, locked firmly once in contact with the pipe, to firmly hold the material during processing All clamping cylinders are controlled by linear encoder to ensure pipe clamping and alignment The clamping pressure is adjusted according to the pipe wall thickness – Main features of the equipment Switching on the clamping device The self-centering jaws (1) and (2) cover the entire diameter range without the need for any fixture operation The inserts are replaceable The intermediate clamps are equipped with clamping cartridges quick-release interchangeable gears covering the entire diameter range: Quick and easy diameter change (< 4 minutes) High utilization factor Feed carriage Wire head mounted on a carriage, sliding along two tracks made of hardened and ground steel “Z” movement guided by preloaded INA linear recirculating roller bearings Carriage moved by a brushless motor acting on a recirculating ball screw No backlash and high rigidity High positioning accuracy on the Z-axis Guide gearbox 1. Driven by an asynchronous servomotor that provides power for the entire required speed range. 2. Reduction ratio obtained entirely by gear set, without belt transmission. 3. Parallel shaft type with case-hardened and ground helical gears and preloaded precision bearings to withstand axial and radial loads. 4. Detection of rotation speed and positioning by rotary encoder connected to the reducer. 1:1 rotation speed ratio between hollow spindle and encoder. High rigidity. High positioning accuracy. Gears and bearings lubricated by an oil recirculation system, with oil cooling and filtration units. Improved heat removal and lubricant quality. Longer bearing life. Mechanical stability against thermal effects. The control box is equipped with two mechanical labyrinths and a continuous air blower on the front side. No lubricating oil leaks, no cooling water ingress into the spindle. Reduced heat generation and power losses. No seal wear. Resistance thermometers are mounted on the gearbox to constantly monitor the temperature of the main bearings
