BCM – Hydraulic Bore Clamp

Hidrofix – Hydraulic Bore Clamp

Application:
The hydraulic bore clamp is ideal for workpieces with complex external contours that require secure fixation during machining.


Once the clamping segments are seated in dedicated, shallow-depth holes located on one side of the workpiece, all five sides can be machined reliably and without obstruction.


Installation and removal of workpieces can be effortlessly carried out using automated handling systems.

HIDROFIX Bore Clamps (Hole Locking Systems) – BCM Series

Bore Clamps (Hole Locking Systems) are mechanical or hydraulic clamping elements specifically designed to lock onto the holes of workpieces. Hidrofix’s BCM Series products are widely used in CNC machines, mold clamping systems, and precision machining applications.

What Are Bore Clamps (Hole Locking Systems) Used For?

✔ Clamping Through Holes: Secures the workpiece by gripping its pre-drilled holes
✔ High-Precision Positioning: Minimizes machining errors by precisely centering the workpiece
✔ Vibration Resistance: Prevents vibration during CNC milling, drilling, and turning operations
✔ Quick Setup: Easily opens and closes via manual or hydraulic/pneumatic actuation
✔ Compact Space Use: Offers an alternative solution where standard clamps won’t fit

Working Principle

  • Insertion: The Bore Clamp is inserted into the hole of the workpiece
  • Expansion:
    • Mechanical version: A mandrel expands when a screw or lever is turned
    • Hydraulic version: Internal mechanism expands under applied pressure
     
  • Locking: The expanding part presses against the inner surface of the hole, securing the workpiece
  • Release: The system is depressurized or loosened to release and remove the workpiece

Main Application Areas

  • CNC Machining Centers (Milling, Drilling, Turning)
  • Mold and Gauge Clamping Systems
  • Precision Positioning of Large Components
  • Special Clamping Solutions in Automotive & Aerospace Industries
  • Fixturing on Measurement and Inspection Equipment
