How to Properly Operate a PCD Reamer

To properly operate a PCD reamer, you should know the proper settings for the machine. These parameters include the optimal set of cutting conditions, Speeds and feeds, DOC ranges, and the correct use of a fine boring tool. Following these guidelines will ensure that the PCD reamer performs as designed. These tips will help you maximize the lifetime of your machine and boost its cutting economy.

Optimal Set of Cutting Conditions

Optimal Set of Cutting Conditions

Optimal set of cutting conditions for reaming a PCD-coated part. It is important to understand the effect of these cutting conditions on the quality of the final hole. The higher the cutting speed, the lower the uncut thickness, and the smaller the feed per revolution, the less force is needed to remove the material. However, as the cutting speed increases, the amount of cutting force decreases, and the resulting surface roughness is high.

Optimal set of cutting conditions for reaming a PCD part is a function of the starting hole diameter, reamer geometry, and the rigidity of the fixture. Other factors to consider when choosing the ideal set of cutting conditions for a PCD reamer include lubrication and stock removal. It is essential to select the best combination of these factors to achieve the optimal results.

Speeds And Feeds

A PCD reamer has variable speed and feed settings that affect its cutting force. These settings can vary from 54 deg to 61 deg. The pitch angle of the cutting blade varies from the normal to the angled, and is determined by the PCD reamer’s manufacturer. A lower speed and feed setting will produce lower thrust and torque. Increased speeds and feeds reduce the friction coefficient, which will increase the cutting force.

A PCD reamer is better suited for high-speed feed processing than conventional carbide reamers. The increased throughput is beneficial as the tool lasts longer. High-speed and feeds are desirable for a PCD reamer, but there are some drawbacks as well. PCD reamers are not suitable for working on ferrous materials. However, they can be used for reaming carbide, bronze, and other abrasive materials. Furthermore, PCD reamers are expensive, as compared to carbide reamers.

DOC Ranges

When using a PCD reamer, it is important to remember that DOC ranges vary by material. Steels and cast iron have DOC ranges of 50 to 80 rms. Aluminum reamers typically impart a finish of eight rms. In addition, reaming can improve hole straightness by about 0.005″ per side. However, you should be aware that DOC ranges can be less than optimal for your specific application, Check out the post right here.

When choosing a PCD reamer, you must determine the type of material to be drilled, the desired speed, the number of holes to be cut, and the dimensional tolerances for the holes. Make sure to consider finish requirements as well when choosing a reamer. There are many varieties of these tools, but it is important to choose the right one for the job. By doing so, you can minimize the risk of surface finish degradation and improve machine productivity.

Using a fine boring tool to correct a PCD reamer

Using a PCD reaming tool can be very beneficial for the precision machining process. Its multiple cutting edges and double entrance make it the ideal tool for producing a perfect valve guide. This tool can also be used for bore location corrections and has a cycle time that is comparable to a guide-padded reamer. However, before using this tool, it is important to learn about the characteristics of a PCD reamer.


Reamers are generally faster and easier to use. This is because reaming does not require the same adjusting as single-point boring. Reaming is more stable and can also impart a smooth surface finish. As a result, this tool is often the preferred choice for precision machining. However, it is important to note that reaming is more common than boring. A PCD reamer can be used to achieve the proper hole size and a fine surface finish.
