Automatic Hydraulic Precision Pointing Machine – Smart End‑Forming for High‑Volume Cold Drawing Lines

  • 6 hours ago
  • 3 min read

Fully automated hydraulic pointing with programmable force, multi‑die concentricity, and quick‑change tooling – delivering consistent, burr‑free points on tubes and bars up to 80 mm diameter.


Why Automatic Hydraulic Pointing Beats Manual and Mechanical Methods

Pointing is the critical first step in cold drawing – a poorly formed point leads to die damage, carriage slippage, and material waste. Automatic hydraulic pointing eliminates these risks by combining:

  • Smooth, programmable hydraulic force – No impact shock, no work hardening, no cracking.

  • Fully automated cycle – Clamping, forming, and retraction without operator intervention.

  • Multi‑die concentricity – Even radial pressure ensures the point is perfectly aligned with the tube/bar axis.

  • Quick‑change tooling – Switch between diameters in under 5 minutes.

How the Automatic Hydraulic Pointing Cycle Works

  1. Automatic loading – Magazine or conveyor feeds tubes/bars one by one.

  2. Clamping – Hydraulic grippers secure the workpiece without marking.

  3. Die closing – Segmented dies (2 or 4) close around the end.

  4. Forming – Hydraulic cylinder advances, reducing the diameter smoothly.

  5. Dwell & retraction – Programmed hold time ensures complete forming; dies open.

  6. Discharge – Pointed workpiece is transferred to the drawbench or stacker.


Materials Processed

  • Carbon steel, alloy steel

  • Stainless steel (304, 316, 17‑4 PH)

  • Aluminum (6061, 6063, 7075)

Real‑World Productivity Gains

A manufacturer of stainless steel hydraulic tubes (304, 25 mm OD × 2 mm wall) switched from lathe pointing to a FangRong automatic hydraulic pointer:

  • End loss reduced – from 120 mm to 45 mm per bar

  • Cycle time – from 40 seconds to 12 seconds

  • Die life in drawbench – increased by 45% (due to perfect concentric points)

  • Operator requirement – from dedicated pointer operator to semi‑attended (one operator runs two machines)
