Introduction to diamond reamer:
Adjustable diamond reamer size 4mm-60mm iron casting precision reaming tool
the diamond reamer supplied by Hualing superhard is divided into adjustable diamond reamer and fixed non adjustable diamond reamer. Adjustable diamond reamer refers to the reamer whose edge diameter can be slightly adjusted several times to expand the re-use reamer, so as to greatly reduce the reamer loss and reduce the processing cost. It is generally used for rough reaming and semi precision reaming. the fixed diamond reamer cannot be similar to that of the fixed diamond reamer If the size is adjusted as above, the machining accuracy is higher. It is generally used for fine reaming and belongs to high precision reamer.
Usage method:
When used, first reassemble the rough reamer on the power head and adjust the front and rear adjusting nuts on the cutter, so that the 1/3 of the cutter body extends into the valve hole and rotates the valve body with the hand, so that the handle feels tight. Then, the foot switch is opened, and the valve body is pushed forward evenly by holding the valve body in both hands. When the cutter body 2/3 passes through the valve hole, it returns; in the process of propulsion, if the handle is getting tighter and tighter, the squeak will be issued. If the open reaming amount is too large, the reamer size must be adjusted smaller; if the hand feeling is very loose and there is no component in the process of pushing, it means that the reaming amount is small, and the reamer size must be increased until the suitable quality is obtained. At this time, the operator's hand feel has certain resistance and is very uniform during the pushing process.
Each reaming only needs one back and forth, and reciprocating for many times will affect the accuracy and the hole diameter. Once the size is appropriate and the reamed valve holes are inspected to be qualified, a batch of valve holes can be completed, and then middle reaming and fine reaming can be replaced in turn. The adjustment method is the same as that of coarse reaming.
If the batch size is not large, only two reamers can be used. At this time, the coarse reamer is used twice, first for rough reaming, and then for medium reaming or fine reaming after adjusting the size.
