Six‑Die Hydraulic Pointing Machine – Superior Concentricity & Efficiency for High‑Volume Tube & Bar End Forming

Six radially arranged hydraulic dies deliver unmatched end concentricity, faster cycles, and smoother surface finish – ideal for stainless steel, titanium, high‑strength alloys, and precision cold drawing lines.

Why Six Dies?

Traditional pointing machines use two, three, or four dies. The six‑die hydraulic pointing machine distributes forming force more evenly around the tube or bar circumference, resulting in:

• Superior concentricity – ≤0.05 mm deviation, essential for thin‑wall tubes and precision drawing

• Finer surface finish – No faceting or die marks; ready for high‑quality drawing

• Higher reduction per pass – Up to 60% diameter reduction in one cycle

• Longer die life – Reduced wear per die due to force distribution

• Faster cycle times – Complete pointing in 3–8 seconds, depending on material

How Six‑Die Pointing Works

Six dies are arranged radially in a cage or rotating head. Hydraulic pressure advances a cone or piston, forcing all six dies inward simultaneously and uniformly. The result: perfectly centered, smooth‑tapered points without the “lobing” or faceting common with fewer dies.

Advantages Over 2‑Die or 4‑Die Pointers

Feature	2‑Die	4‑Die	6‑Die (FangRong)
Concentricity	≤0.15 mm	≤0.10 mm	≤0.05 mm
Surface finish	Faceting possible	Minor faceting	Smooth, no faceting
Reduction per pass	40%	50%	Up to 60%
Die life	Good	Better	Best (even wear)
Suitable for thin‑wall tubes	Limited	Good	Excellent

Materials Processed

• Stainless steel (304, 316, 17‑4 PH)

• Titanium (Grade 2, Grade 5)

• High‑strength alloys (Inconel, Monel, 4140)

• Carbon steel, alloy steel

• Aluminum, copper, brass

Critical Applications

• Medical – Hypotubes, guidewire blanks (extreme concentricity required)

• Aerospace – Thin‑wall hydraulic tubing, actuator rods

• Automotive – Fuel injection lines, precision shafts

• Hydraulic & pneumatic – Small‑diameter cylinder tubes

• Cold drawing preparation – Perfect points for downstream drawbenches

Key Machine Features

• Hydraulic die actuation – Smooth, programmable force; no impact shock

• Automatic cycle – Clamping → die closing → forming → retraction → discharge

• Quick‑change die set – Swap complete die sets in under 5 minutes

• Non‑marring grippers – Protect soft alloys and polished surfaces

• Safety interlocked guarding – Full enclosure, light curtains

• Data logging – Cycle records for ISO/AS9100 traceability

Real‑World Performance Example

A medical device manufacturer needed to point 316L stainless steel hypotubes (6 mm OD × 0.5 mm wall) with concentricity ≤0.08 mm for subsequent drawing into guidewire blanks. A 4‑die swager achieved 0.12 mm – out of spec. After switching to a FangRong six‑die hydraulic pointer, concentricity improved to 0.04 mm, surface finish became flawless, and scrap dropped from 8% to 0.5%.

Integration into Automated Drawing Lines

The six‑die hydraulic pointer is designed as the front end of a high‑precision cold drawing line:

1. Six‑die pointer → perfect, concentric point

2. Precision drawbench → cold drawing to final dimensions

3. Straightener → geometric correction

4. Cut‑off & stacker → finished product
