When we use a deep hole tool, we occasionally need to increase the hole diameter, and the error will be relatively large. What is the reason why the aperture needs to be increased? Next, our staff will give you a brief introduction of their relevant knowledge points.
The design value of the outer diameter of the reamer of the deep hole cutter is too large or there is burr on the reamer cutting edge; the cutting speed is too high; the feed rate is improper or the machining allowance is too large; the main deflection angle of the reamer is too large; the reamer is bent; the chip lump is adhered on the reamer cutting edge; the swing of the reamer cutting edge is out of tolerance when the reamer is grinded; the cutting fluid selection is not appropriate; when the deep hole cutter is installed, the oil stain on the surface of the taper shank is not cleaned or there is oil on the conical surface Knock and bruise; interference of taper shank after the flat tail of taper shank is installed into the main shaft of machine tool; bending of main shaft or loosening or damage of main shaft bearing; inflexible floating of reamer; uneven force of two hands when reaming different shafts and hand reaming holes from workpiece, which makes reamer shake left and right.
