Manufacturing Workflow: CNC Thread Rolling Machine Process Visualization

1. Raw Material Inspection

Incoming stainless rod/blank is checked (per ISO2858 standards) for dimensional accuracy, composition & surface finish.

2. Cutting & Sizing

Material is sawn/cut to desired length using precision CNC cutting systems; ends are chamfered/rounded as needed.

3. Cleaning & Pre-treatment

Surface is degreased and cleaned to ensure perfect adhesion and defect-free threading.

4. Thread Rolling (Cold Forming)

Rod is placed between rotating dies of the cnc thread rolling machine. The material is plastically deformed at room temperature, creating precise, work-hardened threads with superior surface finish and strength.

5. Post-Roll Inspection & Measurement

All threads are checked using Go/No-Go gauges; samples sent for tensile and fatigue tests per ASTM A370.

6. Finishing (Optional) & Packing

Threads receive anti-corrosion coatings or passivation as needed. Product is packed and labeled for shipment.

Comparative Analysis: CNC vs. Flat and Hydraulic Thread Rolling Machines

Choosing the right cnc thread rolling machine involves assessing production volume, thread geometry, material, and finish quality. The table below compares key features of cnc, flat, hydraulic, and mini thread rolling machines:

Machine Type	Max Diameter (mm)	Control Level	Torque Output	Adaptive Dies	Energy Consumption	Cycle Time (s)	Thread Accuracy (μm)	Applications
CNC Thread Rolling Machine	64	Full CNC, HMI	Medium-High	Automatic	Low	8–12	±4	Precision rods, anchor bolts, special threads
Flat Thread Rolling Machine	40	Manual/Semi-auto	Medium	Manual	Medium	15–18	±8	Standard bolts, short rods
Hydraulic Threading Machine	100	PLC/Manual	High	Manual	High	25–35	±10	Large diameter rods, pipeline joints
Mini Thread Rolling Machine	12	Manual	Low	Manual	Very Low	10–16	±8	Small precision screws, electronics

CNC: Highest flexibility and efficiency.
Hydraulic: Best for large, high-strength rods.
Flat/Mini: Lower cost, best for standard or small batch jobs.
