In this article, through compari- son of technical data, the authors mainly introduce LF-70 and LF-90 hydraulic diamond core drill machine from Boart-Longyear in USA, provide some suggestion to domestic consumers.
We have been studying the tunnel advanced detection technology and its application for several years, put forward an integrated prediction method combining advanced detecting geological radar with advanced horizontal core drill, and obtained preferable effect in many practical projects.
The thrust force and surface roughness of core drill with drill parameters (grit size of diamond, thickness, feed rate and spindle speed) in drilling carbon fiber reinforced plastic (CFRP) laminate was experimentally investigated in this study.
Taguchi analysis of drilling quality associated with core drill in drilling of composite material
This and other blocks were sampled using portable core drill.
Instrumentation using a cannulated core drill was developed and assessed in an anatomic safety study.
Its new CS14 core drill along with all attendant equipment recently arrived in Madagascar and is on site at the Mountain of Gold project.
