Brochexpress — The Art of Precision

What if your 3-axis machining center became 4 Axes

The BHF5-EMSR-PNE motorized chuck spindle fits any vertical machining center and adds a full rotary axis — without modifying the CNC control.

3-axis machining center with BHF5-EMSR-PNE chuck spindle
The context

Machine a part
on 4 faces
in a single setup

  • On a standard 3-axis machine, every repositioning introduces cumulative error
  • Manual re-clamping slows the cycle and ties up the operator
  • A dedicated 5-axis machine is an investment of several hundred thousand euros
  • There is an alternative: a rotary chuck spindle mounted on the table
BHF5-EMSR-PNE chuck spindle
The solution

BHF5-EMSR-PNE

A motorized chuck spindle that mounts on the milling table through the existing T-slots. No drilling, no machine modification.

  • Pneumatic clamping at 6 bar — up to 400 daN of force
  • Integrated synchronous motor — 5,000 rpm
  • Runout < 2 µm
  • Lenord+Bauer sin/cos encoder for precise positioning

Integration
in 3 steps

01
Mount on the table 4 × M6 screws in the T-slots — standard 100 mm spacing. No drilling.
02
Connect hose & air HFX hose 2.9 m to the cabinet. Filtered + regulated + lubricated air supply.
03
Dry contact on the CNC A single on/off signal from the CNC is enough. No software changes.
