1、What is a PCD reamer

Polycrystalline Diamond (PCD) cutting tools or PCD reamer apply in the process of cutting aluminium, brass and copper, graphite, and other materials like wood, plastic, and carbon-fiber-reinforced polymer (CFRP).

Basically, you can use them to obtain high abrasive resistance and high hardness.These motives result in a longer life for the cutter in comparison to conventional ones. Also, they are customed to fit your exact measurement specifications.

In addition, it is used is to enlarge a hole that is in close tolerance range with a high surface finish, concentricity, and cylindricity.

2、Problems when using a PCD Reamer

1） Increased the aperture size
2）The aperture size becomes smaller
3）Insufficient tool life
4）The precision of the reamed hole is out of tolerance
5）Reamer tooth chipping
6）Reamer shank broken
7）The center line of the hole may not be straight
8）The surface of the hole's interior has several visible features

9）Inner holes have a higher surface roughness
10）The inner hole is not circular

3、Solutions to be solved

1）Reduce the outer diameter  in accordance with the situation. Reduce the cutting speed; appropriately alter the feed rate or reduce the allowance for machining; select a cutting fluid that has more efficient cooling; examine various equipment before machining to reduce the possible impact.

2）Change the diameter of the outside of your PCD Reamer. You can adjust the speed of cutting and feed. Select an oily cutting liquid with excellent lubricating properties. If you are trying cutting for the first time be sure to alter the allowance as well as improve the sharpness of your PCD reamer.

3）You can choose the right PCD reamer material according to the processing material. The PCD reamer may also be used.

4）Regularly replace the guide sleeve; lengthen the guide sleeve so that it improves the accuracy of the guide sleeve as well as the reamer clearance. Immediately fix the machine tool, and adjust the spindle bearing clearance.

5）Modify the size of the hole that was pre-machined or reduce the material's hardness or employ a negative rake angle PCD reamer or a carbide reamer to keep the swing within a safe limit.

6）Modify the size of the pre-machined aperture or alter the allowance distribution and then select the cutting quantity reasonably; reduce the number of reamer tools or expand the chip area or reduce the gap between the teeth by one tooth.

7）increase the reaming or boring process to make the hole more even; adjust the appropriate PCD reamer, then replace the reamer with the guide or lengthened cutting part.

8）Reduce the reaming allowance and reduce the clearance angle of the cutting component; adjust the machine tool spindle.

9）Reduce the speed of cutting; select the cutting fluid based on the material to be processed. Adaptively reduce the reaming allowance; reduce the number of PCD reamer teeth in accordance to the specific situation.

10）To control hole position tolerances during the preprocessing procedure using a certified PCD-reamer. Use an unequal pitch tool as well as larger and more accurate guide sleeves.
