RCD-250 Pressure Controlled Coring Machine


The GCTS RCD-250 Pressure Controlled Coring Machine features a pressure controlled feeding mechanism for even sample coring and is able to achieve a large range of spindle speeds to provide optimum performance when preparing test specimens, regardless of the properties of the material being sampled.

 

  • 1.5HP electric motor with 12 adjustable spindle speeds from 150 through 4,200 rpm.
  • Drilling rate controlled by both pressure and speed and automatic down-feed mechanism with 250-mm travel.
  • Rigid Multi-Column drill support frame to eliminate ridges on specimen.
  • Includes quick-latch specimen holder for coring 100 mm (4 in.) specimens from 150 mm (6 in.) compacted samples.
  • Wide variety of Coring Barrels to choose from.

The GCTS Laboratory Coring Machine is capable of achieving a large range of spindle speeds to provide optimum performance when preparing test specimens, regardless of the properties of the material being sampled. All accessories are included (water swivel, drip pan, sample holder. Other standard or custom barrels are also available.


The main feature that sets this coring machine above any other is the force/stroke control to optimize feeding rates for superior performance when coring material, which is not homogeneous.

SPECIFICATIONS
