Thread Rolling Machine PHMTOOLS

The Thread Rolling Machine PHMTOOLS (Penghao Machinery model Z28-40) is a high-speed, heavy-duty machine for forming external threads by cold rolling. It is used for screws, rebar, and other threaded rods and is suitable for carbon steels, alloy steels and non‑ferrous metals in industrial manufacturing, construction and fastener production.

Key specs include processing diameter 4–28 mm, maximum rolling pressure 120 kN, spindle speeds 36/47/60/78 r/min, spindle feed speed 5 mm/s, production capacity 3–6 meters per minute, main motor 4 kW, hydraulic power 2.2 kW, cooling power 0.12 kW, pitch range 0–3 mm, host size 1400×1400×1420 mm and weight ~1000 kg.

The machine handles roller (workpiece) diameters from 4 mm up to 28 mm. Typical pitch range (ordinary) is 0–3 mm. For special pitches or diameters outside this range, contact the supplier to discuss custom tooling or machine configuration.

Yes — the PHMTOOLS thread rolling machine is designed to produce threads of effectively unlimited length, constrained only by your material feed and handling setup.

Rated production capacity is 3–6 meters per minute. Actual throughput depends on material, diameter, pitch, operator setup and any downstream handling; lighter diameters and coarser pitches generally allow higher line speeds.

Spindle speeds selectable are 36, 47, 60 or 78 r/min. The dynamic spindle feed speed is 5 mm/s, which helps achieve efficient cycle times and consistent thread formation.

It can process carbon steel, alloy steel and non‑ferrous metals. Thread forms include common metric/imperial external threads, trapezoidal threads, modulus threads, and it can perform forming, sliding/abrading, knurling and related cold forming operations.

Cold rolling improves material properties: for rebar the machine can increase tensile strength by ~20–30%, fatigue strength by ~40–60% and corrosion resistance by ~50–200% compared with cut threads. The product meets or exceeds relevant international mechanical performance standards when processed correctly.

Electrical power: main motor 4 kW. Hydraulic power unit rated 2.2 kW with cooling power 0.12 kW. Exact electrical supply voltage and frequency are not listed in the basic spec — confirm site voltage/frequency and power feed requirements with the supplier prior to installation.

Host machine dimensions are approximately 1400 × 1400 × 1420 mm and weight is about 1000 kg. The hydraulic station is about 650 × 600 × 640 mm. Allow additional clearance around the machine for material handling, maintenance and any optional feeders.

Optional items include automatic feeders with PLC control or automatic feeders without PLC. Other common options (available on request) include customized rollers, special tooling for non‑standard pitches/diameters, guarding packages and material handling/unwinding equipment.

The PHMTOOLS is built with a heavy-duty frame and components for long service life. Routine maintenance includes checking and replacing hydraulic oil/filters, inspecting and replacing rollers/tooling as needed, lubrication of bearings and keeping the machine clean. Follow the supplier's maintenance schedule for best reliability.

Standard safety measures include properly installed guards, emergency stop, trained operators, lockout/tagout for maintenance, and routine hydraulic inspections to prevent leaks. Operators should be trained in safe setup, loading/unloading and emergency procedures. Confirm specific safety equipment and guarding with the supplier.

Thread rolling produces high-quality, accurate threads due to cold forming; the product spec notes high precision. Exact tolerance capability depends on tooling, material and process parameters — request the supplier's tolerance data or testing samples for the specific material and thread required.

Warranty, spare parts availability and after‑sales support can vary by supplier and purchasing agreement. Contact PHMTOOLS/Penghao Machinery or your distributor for details on warranty terms, spare parts pricing, lead times, installation support and operator training options.
