How do you grind a reamer?

MoreSuperhard vitrified cylindrical diamond wheel is used for grinding PCD reamer. It enjoys high grinding power, long working life and good surface quality.

Grinding PCD reamer with the OD of the vitrifed diamond wheel . You may want to experiment with the sharpening first , as this is the area you will be grinding off to make the pilot anyway . For a straight reamer it's often enough to grind the reamer to size. Grind a slight back taper (about .001 over an inch) to prevent the reamer from sticking. If the margin (circular lands) gets too large you can relieve the edge, leaving a margin about .004. If you reduce the diameter too much you may have to resharpen the chamfered cutting edges.

Applications of PCD reamers

- Cylindrical vitrified diamond grinding wheel is used for PCD tools grinding with large cylindrical grinding machines. The PCD tools in automotive industry include PCD profile cutters, PCD reamers and PCD milling cutters. 

- Reamers are an effective option for hole finishing. Reaming with a PCD tool allows the user to ream holes faster, to tighter tolerances and produce cleaner-edge holes than is possible with carbide or HSS tooling.

- Aluminum engine blocks also require the truer holes that PCD reaming produces to achieve required performance levels. Aerospace and automotive manufacturing industries.
