What Is an Adjustable Reamer?
Adjustable reamers are cutting tools used for the purpose of finishing holes drilled with a drill, etc., to a predetermined size or shape to achieve even higher precision.
The unit is counted in pcs. The shank diameter and adjustment range are set in detail depending on the size, and some of the small ones include a small number of blades.
This is essential for machining holes in pipes, seat tubes, etc., where delicate inner diameter adjustment is easily attainable.
After measuring the location and size to be used, the appropriate one for the application should be selected for use.
Uses of Adjustable Reamers
Adjustable reamers are capable of drilling holes with a much higher degree of completion than other tools.
They can be used for machining metal products around us, such as motorcycles, automobiles, and other large metal products.
It can also be used for various repairs, making it a very useful tool.
Principles of Adjustable Reamers
Adjustable reamers are a type of drill blade that can be quickly adjusted in terms of blade diameter and tooth profile dimensions.
Adjustable reamers should always be used in right-hand rotation, and care should be taken to prevent chips and debris from getting into the groove when replacing the blade.
Adjustable reamer nuts should be tightened firmly to prevent loosening of the blade, and the reamer take-up allowance should normally be adjusted between Φ0.05 mm and Φ0.15 mm.
To ensure the accuracy of the adjustable reamer, all blades should be replaced with new blades (replacement blades) in cases where even one adjustable reamer blade is missing or severely worn.
Adjustable reamer cutting blades are often straight blades, but in cases where the hole itself has a keyway or oil groove, or where the hole is deep, twisted blades are suitable for general use.
Before using an adjustable reamer blade, it is important to have some understanding of the hardness and material of the object to be drilled, and how it responds to vibration caused by the operation of the reamer itself.
Some materials may be affected by the vibrations caused by the adjustable reamer itself, so you should refrain from drilling at high power.
