The spiral reamer can improve the machining efficiency and precision, obtain the surface roughness equivalent to the 7~9 grade finish, and its service life is 1~2 times higher than the standard reamer. The reamer has good manufacturability and can be used for machining discontinuous surfaces.
Standard reamer refers to straight groove reamer,
The spiral reamer life was improved by increasing the work partly because the unit length of the total length of the cutting edge, titanium nitride (TiN) thin films with high hardness, reduce the friction between the reamer and the workpiece, and reduce the required cutting, H hole tolerance zone, the minimum limit is 0, 7 accuracy rating IT7,
H7 is the diameter of the hole is 0 to 0.015 tolerances, such as Phi 10 reamer diameter Phi 10.01 in general to Phi 10.015, cobalt coating chamfering HSS-CO material, a full range of 6.3mm 60mm, 60 degrees to 90 degrees, 120 degrees, three edges and single edge on, chamfering cutter is assembled on the milling machine, drilling machine, planer machine, chamfering machine for 60 or 90 degrees and the taper workpiece chamfering,
Mold corners. Also called chamfering chamfering device, not only suitable for ordinary machining chamfer, features more suitable for precision machining difficult chamfering chamfering and deburring machining, can complete cone. It is suitable for small cutting quantity machining.
15 degree spiral angle supports both upper cut support lower cut contact area increased by 20% and increased resistance is very small
H7 is the tolerance of the diameter hole is 0 to 0.015, such as the diameter of the reamer 10 is generally between 10.01 to 10.015,
