inner cool drill

The cutting force is the sum of all drilling holes on all sectors. Due to the formulation of sectorizing model also need to use a lot of turning test according to the bit adjusted blade geometry and cutting data, and thus requires the development of a new model,...

drilling operations

In drilling operations, the bit rotates around a vertical shaft and moves in the axial direction. The soil is cut under the action of torque and axial force of the bit, and crushing and crushing pressure and a centrifugal force working code, where the land was flowing towards...

Drill material

The drill bit used in printed circuit boards are usually made of solid concrete, because the epoxy glass cloth copper clad panel cutouts. The very fast wear the so-called binder cobalt powder, tungsten carbide powder, matrix, by compression and sintering. Usually contains tungsten carbide cobalt containing 94%, 6...

Deep hole twist drills

Quick processing time Drill geometries allow to process security in turning and drilling, which can be removed without the need for Beck. This shorter cycle times and thus reduces the cost of the hole. The minimum cost of production High performance cutting huge increases in productivity compared with...
