Brand new About this product
The Three Roll Hydraulic Thread Rolling Machine by National Cutting Tools is an advanced three-die cold thread rolling machine engineered specifically for rolling external threads on hollow tubes, thin-wall pipes, and tubular scaffolding screws. When rolling threads on hollow tubing with a two-roll machine, the opposing radial forces can easily crush or ovalize thin-wall pipes; a three-roll machine applies three synchronized radial forces at 120-degree intervals, holding the tube concentric and supporting the wall from three sides throughout the roll stroke. Driven by three synchronized hydraulic cylinders and three geared roll spindles, the machine produces flawless, uniform thread profiles on hollow scaffolding jack tubes, conduit pipes, and structural tubular connectors without requiring internal mandrels. The machine accommodates pipe diameters from 16 mm up to 100 mm in both in-feed and continuous through-feed modes. Key Features Three-Point 120° Radial Pressure: Distributes rolling forces symmetrically around the pipe circumference, preventing tube crushing and ovality. Mandrel-Free Thin-Wall Threading: Rolls deep trapezoidal and ACME threads on thin-wall tubes without requiring internal support mandrels. Three Synchronized Spindle Drives: Precision gear transmission rotates all three rolls at identical speeds for slip-free cold forming. High-Pressure Hydraulic Power Unit: Proportional hydraulic control delivers smooth, balanced infeed pressure across all three roll slides. In-Feed & Through-Feed Capability: In-feed handles short threaded pipe ends; through-feed rolls continuous long threaded pipes and rods. Touchscreen HMI Parameter Control: Allows programming roll infeed speed, rolling time, and pressure dwell for repeatable batch production. Applications Rolling hollow screw threads on scaffolding hollow base jacks and leveling spindles External thread rolling on thin-wall structural steel and conduit pipes Automotive steering sleeves, tubular tie rods, and shock absorber tubes Oil and water well filter pipe perforated tube thread rolling Manufactured and calibrated at National Cutting Tools in Focal Point, Ludhiana. Tested on hollow pipe samples for wall concentricity, roundness, and thread gauge fit before factory dispatch.
