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.

If I have a PCD cutting tool grinder, can I grinding the cylindrical of reamer?
Recently, we met some customers who were consulting diamond grinding wheel for reamer cylindrical grinding. After inquiring some specific information, we found that these customers all had something in common -- the main reason is: the grinding machine does not match the grinding requirements. For example, the customer has a PCD tool grinding machine, and now he wants to cylindrical grinding the reamer, but there is no special cylindrical grinding machine and do not know what grinding wheel should be matched with grinder.
Can our grinder grind the reamer cylindrical?
Use 198NC automatic grinding machine?
Reamer cylindrical grinding is suitable for manual processing equipment，because there are many factors affecting the cylindrical grinding.
How is the rotation of the cylinder realized with manual equipment?
Using variable frequency motor with adjustable speed.
Is the same with EWAG RS9 and 12?
I thought it had to be an automatic grinder to grind the cylindrical, because the domestic customers usually used cylindrical grinding wheel, but we encountered less foreign. It is estimated that using the diamond cup grinding wheel to direct grinding of the cylinder. In China, most using grinding wheel with diameter 300-350mm to grinding the cylinder.
In that case, we need to purchase a new cylindrical grinding machine and more grinding wheels.
Domestic may be a lot of people, who manufacturing the carbide tools originally, estimate they have cylindrical grinder. In addition to the cost, do you think there are any differences in efficiency and accuracy between using a manual tool grinder and an cylindrical grinder?
Cylindrical grinding machine without constant pressure, PCD cutting tools will be broken as grinding wheel blockage. And cylindrical grinding machine cannot be measured the grinding amount by CCD, must be measured by the contact method of thousands of minutes per cent caliper, which requires experienced master operation, otherwise it will be easy to measure PCD collapse!
Then the formula of grinding wheel does not need to be changed, right?
6A2 vitrified diamond grinding wheels we sold may be used for grinding cylinder or grinding end face and also for grinding cylinder. Our customers give us the feedback: there is no problem uses the same grinding wheel to grind the cylinder and the edge bevel.

Drawing dies are widely used, such as high-precision wires used in electronic devices, radars, televisions, instruments and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires are all drawn with diamond drawing dies. The diamond wire drawing die made of natural diamond has strong wear resistance and extremely high service life due to the use of natural diamond as raw material.
