Start with the workpiece range

The working diameter separates these two automatic thread rolling machine options most clearly. YYTM002 is specified at a 120 mm working diameter and 650KN maximum roller pressure. The Automatic Hydraulic Thread Rolling Machine is specified for 4 to 48 mm workpieces and 150KN maximum roller pressure.

Both machines are intended for external roll threads, including general pass threads, T-screw roll threads, and modulus threads. Their material window is also shared: carbon steel, alloy steel, and non-ferrous metals with elongation over 10%, tensile strength below 1000 MPa, and HRC below 37.

For automatic thread rolling rolling machine making, picture the production line around its largest regular workpiece. A 4 to 48 mm screw rod range points to the Automatic Hydraulic Thread Rolling Machine. A 120 mm requirement points to YYTM002, with the thread form, material condition, and tooling arrangement included in the quotation request.

Compare the operating specifications

The shared 5 mm/s feed speed and 100 mm maximum roller width make those useful baseline checks, but they do not define the machine choice. Pressure, workpiece diameter, power, and roller size create the practical difference between the two configurations.

YYTM002 has the higher listed roller pressure and the larger roller outside diameter. Its 22 kW main power and 7.5 kW hydraulic power should be included in the plant electrical review. The Automatic Hydraulic Thread Rolling Machine lists 4 kW main power and 2.2 kW hydraulic power, giving the smaller-diameter configuration a lower stated power requirement.

Interfaces and working movement

Both machines use PLC control, so the control-system comparison starts with a shared automation platform. The specified motion details differ in the shaft angle: YYTM002 uses ±15°, while the Automatic Hydraulic Thread Rolling Machine uses ±5°. Include the required thread form and workpiece drawing when asking us to match the rolling arrangement.

The roller dimensions also guide tooling discussions. YYTM002 lists a 290 mm outside diameter and 100 mm bore diameter. The Automatic Hydraulic Thread Rolling Machine lists a 120 to 170 mm roller diameter. Send the target roller diameter, thread pitch, and workpiece diameter together so the tooling discussion matches the selected machine.

The two machines also use different control descriptions. YYTM002 is listed with PLC and hydraulic cutting, while the Automatic Hydraulic Thread Rolling Machine is listed with a PLC control system. Keep the cutting mode and the desired production sequence in the equipment brief instead of treating the two control descriptions as interchangeable.

Plan maintenance around the configuration

Maintenance planning should follow the hydraulic system, PLC controls, movable shaft, and rolling tooling on either machine. Both product descriptions specify Cr12 cutting blades, so blade material belongs in the spare-parts discussion. The roller dimensions and shaft angle should also be recorded with the selected machine configuration.

The service plan changes with the machine's operating scale. YYTM002 brings a 650KN maximum roller pressure, 22 kW main power, and 7.5 kW hydraulic power into the maintenance and electrical review. The Automatic Hydraulic Thread Rolling Machine brings 150KN, 4 kW, and 2.2 kW values into that same review. We can provide overseas engineer support for installation and technical maintenance, and we can discuss a customized interface for the production flow.

For a live production example, measure the largest screw rod in the order schedule before choosing the machine. Then compare its diameter and material condition with the selected model's working and material limits. For the smaller machine, the relevant working window is 4 to 48 mm. For YYTM002, the listed working diameter is 120 mm.

Match the model to the purchase brief

YYTM002 suits a production brief centered on a 120 mm working diameter, 650KN maximum roller pressure, larger roller tooling, and higher listed main and hydraulic power. The Automatic Hydraulic Thread Rolling Machine suits a 4 to 48 mm workpiece range, 150KN maximum roller pressure, 120 to 170 mm roller diameter, and lower listed power values.

Use our Automatic Hydraulic Thread Rolling Machine page when your workpieces fall within the 4 to 48 mm range. Review YYTM002 Automatic Thread Rolling Machine when the production brief calls for the 120 mm working diameter and 650KN maximum roller pressure.

Send a complete machine brief

Choose the model from the workpiece diameter first, then align pressure, roller diameter, shaft angle, and plant power with the production plan. Send us the workpiece drawing, material grade and mechanical condition, thread form and pitch, required quantity, plant voltage, and preferred roller dimensions so we can prepare the quotation around the correct machine.
