Reaming

 

a method of machining holes by cutting (after drilling and countersink reaming) with a multiblade cutting tool called a reamer. As a result of rough reaming, an allowance of not more than 0.5 mm in diameter is removed, providing surface roughness of class 7 and a precision of class 3. In finish reaming, an allowance of not more than 0.2 mm is removed, providing a surface roughness up to class 9 and a precision up to class 2.

As well as the Turbocaser Express and Turborunner, the company has a developed a high-speed reaming system, Shalerunner, for the shale fracking industry.
The turbine powered reaming capability of the Turbocaser Express enabled the new record of 26,318 ft to be reached successfully.
The standard pegged glenoid acted as the control in this analysis by quantifying bone removed to simulate eccentric reaming to correct each size defect.
For the small defect, the 8[degrees] wedge posterior augment glenoid conserves 58% more cancellous bone, 26% more cortical bone, and 50% more bone overall than that using eccentric reaming.
Pipe reaming was the more feasible choice, due to some concerns we had about pipe bursting in this application," Saye says.
Pipe reaming is similar to static pipe bursting in that the host pipe is split by a cutting head and its fragments removed to allow the new pipe to be pulled into the same location as its predecessor.
Eccentric reaming is a straightforward technique with a number of advantages.
17) Thus, techniques that preserve subchondral glenoid bone and minimize glenoid reaming may prove to be superior and provide long-term fixation (Figs.
The pipe reaming process, an assemblage of the power and versatility of a horizontal directional drill and a modified backreamer, is the basis for the pipe reaming process.
The project consisted of 160 linear feet of 24-inch PVC to be installed by open-cut because of a PI in the line and its location, 1,480 feet of 24-inch DIPS HDPE SDR 17 to be installed by pipe reaming, rehabilitation of three manholes and replacement of two manholes on the continuous line with three manholes removed and replaced away from the primary work site.
Facing the prospect of replacing hundreds of thousands of feet of old AC pipe, project owners and contractors are faced with what they must do to comply with environmental regulations to properly dispose of old AC pipe removed from the ground, pieces of broken pipe removed in slurry during pipe reaming operations, and whether it is permissible to leave broken AC pipe segments in the ground after pipebursting procedures.
