Deep hole cutter is a kind of equipment widely used in deep hole machine tool processing. People all know that the size of deep hole will lead to many problems, so when using deep hole cutter, we should pay special attention to it. The diameter of deep hole cutter increases, and the error is large. The treatment methods are as follows. The reason why the above problems appear when machining with deep hole tools is that the planning value of the reamer's outer diameter is too large, or the reaming cutting edge has burrs, the cutting speed is too high, the feed rate is inappropriate or the machining allowance is too large, the reamer's main deflection angle is too large, the reamer is tortuous, the reaming cutting edge is adhered with swarf, the reaming cutting edge is poorly swung during grinding, and the cutting fluid is not selected properly.
When the reamer is installed, the oil stain on the surface of the taper handle is not cleaned or the taper surface is bruised, the flat tail of the taper handle is offset and installed into the machine tool spindle, the taper handle taper is dry, the spindle is tortuous or the spindle bearing is too loose or damaged, the reamer is not sensitive to floating, and the force of both hands is uneven when reaming holes on different axes from the workpiece, making the reamer shake left and right.
The above problems will cause problems in the processing of deep hole tools. If you want to deal with them, you can appropriately reduce the reamer outer diameter and reduce the cutting speed according to the specific situation; Properly adjust the feed rate or reduce the machining allowance, properly reduce the main deflection angle, straighten or discard the twists and turns of the unusable reamer, and carefully trim it to be qualified with an oilstone.
