1)In the machine tool can complete inner hole drilling, boring, nesting, rolling processing.When processing, rotation, cutting tool workpiece feeding, cutting surface (or boring bar) via the crown oil into the cutting zone, lubrication, cooling and chip area, wrapped with chip to chip in the front row.

2)Used when drillingBTAInternal chip removal process.Boring when using forward (side) of the head of a bed line of cutting fluid, chip removal process.

3)The machining precision of machine tools:

Precision drilling: when the apertureIT9-11.The surface roughness:Ra6.3。

Precision rough boring: when the apertureIT9-10.The surface roughness:Ra6.3。

Precision fine boring: when the apertureIT8-9.The surface roughness:Ra3.2。

Precision roll: when the apertureIT8-9.The surface roughness:Ra0.4。

The straightness of machining hole: Less than0.15/1000。

The export of hole deflection processing: Less than0.2/1000

The machining efficiency of machine tool:

Cutting speed: according to the cutting tool material, structure, material and workpiece is in commonly50-100m/min。

Feed speed: according to the processing conditions, in generally40-100mm/min。

Boring machining allowance largest: according to the case, determine the cutting tool structure, material and workpiece, generally no more than30mm。

Machine tool main parameters:
