18mm, therefore it is not suitable for the processing of small diameter bore.Occur lathes of some processing small diameter bores, but its property currently on the market
Can be not perfect, and will appear problems with often in processing small diameter bore：(1) when boring aperture, it is also easy to produce drilling tumor, drilling is not
Easily discharge easily causes drilling blocking and causes bit wear and fracture；(2) drill diameter is smaller, and cutter and hole workpiece to be drilled are continuous
Contact, drilling process heat dissipation is bad, and drilling temperature is excessively high, and condition is created to the generation of drilling tumor；(4) it is easily produced on finished surface
Raw built-up edge, squama thorn and crizzle etc., keep workpiece machining surface finish and geometric accuracy not high.Therefore, it nowadays lacks
It is few it is a kind of it is simple in structure, reliability is high, the permanent magnetism drilling machine of reasonable design, so that cutter is connect with hole workpiece generating period to be drilled
Touch, increase instantaneous drill thrust, reduce drilling temperature, and short the time required to drilling, improve workpiece surface hole to be drilled finish and
Machining accuracy.
