Traditional thread cutting causes metal loss and weakens the workpiece’s structural strength. It also leads to low consistency and slow production speed. A CNC thread rolling machine forms threads via metal plastic deformation. It delivers burr-free, high-strength threads with stable rebar threading speed for batch industrial production.
Complete Parameters of CNC Thread Rolling Machine Series
YG Machinery launches three mature CNC thread rolling machine models for diverse demands. Standard, upgraded, and fully automatic types cover small and large batch processing. All models support 16-40mm diameter rebar thread making.
We also provide customized special models with processing ranges from 10mm to 100mm to meet special processing size requirements.
Looking for Heavy-Duty Hydraulic Thread Rollers or Compact Models? > In addition to standard construction rebar threaders, we also supply Hydraulic 2-Roll & 3-Roll Thread Rolling Machines for precision fasteners (bolts/screws), as well as compact, user-friendly portable models for light workshop tasks.

What Working Principle Does a CNC Thread Rolling Machine Adopt?
A CNC thread rolling machine uses chipless cold forging technology for thread forming. It differs greatly from traditional cutting processing methods. It relies on physical extrusion instead of metal cutting to shape threads.
High-hardness rolling dies rotate with precise CNC system control
Dies apply uniform pressure on the surface of fixed metal workpieces
Metal material produces plastic deformation and flows into thread grooves
Integrated thread structure takes shape without any material loss
Workpiece grain structure becomes denser for higher tensile strength
This processing method avoids thread burrs and surface damage. It effectively improves finished product durability and assembly tightness.
Core Advantages of YG CNC Thread Rolling Machine
Our CNC thread rolling machine has multiple practical advantages for industrial processing. It balances processing accuracy, production speed, and operating cost perfectly.
High processing efficiency: The upgraded model completes forming in only 8 seconds. The automatic model supports one-touch operation to save labor time.
Improved thread strength: Cold extrusion hardens the metal surface. Rolled threads resist tension and fatigue better than cut threads.
Zero material waste: The chipless rolling process retains all raw materials. It reduces long-term production costs for factories.
Stable precision output: CNC digital control ensures consistent thread size. It meets unified standards for batch production.
Wide compatibility: It covers a 16- 40 mm diameter range. It adapts to most conventional rebar and bolt processing needs.
How to Judge a Reasonable Rebar Thread Rolling Machine Price?
Many factory buyers pay close attention to rebar thread rolling machine price before procurement. The final budget varies by machine type and functional configuration.
Standard YGS-40 models suit small-batch and low-frequency processing. It is cost-effective for small processing plants and construction teams. The upgraded YGT-40 improves rebar threading speed greatly for medium-volume production.
The fully automatic YGA-40 supports one-touch unmanned operation. It fits large-scale, high-frequency batch processing lines. Users can select models according to daily output demands to avoid over-investment.
Wide Application Scenarios of CNC Thread Rolling Machine
The high-precision CNC thread rolling machine serves multiple industrial fields. It is widely used for standardized threaded part processing and construction rebar fabrication.
Building construction engineering: Process rebar end threads for steel bar connection. It meets high-standard building reinforcement requirements.
Mechanical manufacturing industry: Produce high-strength bolts, studs, and mechanical fasteners. It ensures stable assembly precision.
Automotive and transportation: Fabricate suspension and engine threaded components. Dense grain structure improves vibration resistance.
Municipal and bridge projects: Make anchor bolts and bridge connection parts. Finished threads feature strong durability and stability.
Hardware batch processing: Support standardized mass production of various threaded hardware accessories.
Overseas Project Case of Rebar Thread Rolling Machine for Sale
A professional construction material processing factory in Poland purchased our YGT-40 upgraded model in early 2026. The client mainly serves local construction and bridge projects. It focuses on mass rebar threading and custom fastener processing for engineering suppliers.
The client previously adopted traditional manual thread cutting equipment. Old processing methods left obvious burrs and uneven thread sizes. The low rebar threading speed could not support bulk order delivery. It often caused delayed shipment and high product rejection rates.
After upgrading to our CNC thread rolling machine, the whole production process was optimized. The stable 8-second fast forming speed effectively doubles their daily production output. All finished rebar threads are burr-free, with uniform size and higher tensile strength. The finished products fully comply with local European engineering acceptance standards.
The client shared real and reliable feedback after two months of continuous full-load operation. They stated: “This rolling machine runs stably with an extremely low failure rate. The thread precision and surface quality meet strict European construction standards. It greatly reduces our defective rate, rework time, and overall production costs.” This practical case proves the stable performance and high cost performance of our thread rolling equipment for overseas industrial batch processing.
FAQs About CNC Thread Rolling Machine Selection and Operation
What is the difference between rolling and cutting threads?
Rolling strengthens metal structure without material loss. Cutting removes metal and weakens thread strength.
Does the machine support customized thread length?
Yes, we support personalized thread rolling length and die configuration customization.
What range of rebar diameters and thread lengths can your thread rolling machine process?
Our standard rebar thread rolling machines process bars with diameters ranging from 16mm to 40mm. Standard models support thread lengths up to 80mm, while our high-efficiency/automatic models can extend thread lengths up to 100mm to meet special engineering requirements.
How does cold thread rolling compare to traditional cut threading?
Cold thread rolling is a non-cutting process that displaces metal rather than removing it. This compacts the grain structure, increasing the joint’s tensile strength by 20%–30%, fatigue resistance by 40%–60%, and corrosion resistance by up to 200% compared to raw rebar.
Can the machine roll both right-hand and left-hand threads on deformed rebars?
Yes. The machine features built-in rib-peeling and automatic blade opening/closing mechanisms. By adjusting or switching the rolling head and dies, it can easily produce both left-hand and right-hand threads on standard ribbed/deformed steel rebar.
How long do the rolling dies last, and how easy are they to replace?
Made of high-grade alloy steel (such as Cr12MoV), a set of quality rolling dies can typically process 3,000 to 5,000 rebar ends under standard operation. They are modular and can be quickly replaced with standard hand tools to minimize site downtime.
Is the machine suitable for outdoor construction sites and restricted environments?
Absolutely. Operates with no open flames or hazardous emissions, making it safe for urban, high-rise, and underground tunnel construction. Heavy-duty housings and optional mobility wheels ensure easy relocation across job sites.
