TK21100Deep hole drilling and boring machine

A) The basic technical performance of machine tools:

1) In the machine tool can complete inner hole drilling, boring, nesting, rolling processing.

2) When processing, rotation, cutting tool workpiece feeding, cutting surface through the oiler grant (or boring bar) into the cutting zone, cooling, lubrication cutting area and take away the scraps.

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

Chip technology.

4) According to the needs of processing technology, can be installed tool box, tool rotation.Reduce the workpiece speed, improve the machining efficiency, ensure the quality of machining.

5) The machining precision of machine tools:

Precision rough boring: when the apertureIT8-10.The surface roughness:Ra6.3。

Precision fine boring: when the apertureIT7-9.The surface roughness:Ra3.2。

Precision roll: when the apertureIT7-9.The surface roughness:Ra0.4。

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

The export of hole deflection processing: Less than0.5/1000。

6) 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 generally0.1-0.4mm/r。
