有关济南手板模型深孔加工的3种方法：

 

3 methods of deep hole processing of Ji'nan hand model:

 

1、接长柄麻花钻在通用机床上加工。接长柄麻花钻就是在普通麻花钻上焊接长柄。

 

1 、 the long handle twist drill is machined on the universal machine tool. A long handled twist drill is a long shank welded on an ordinary twist drill.

 

由于钻削时轴向力大，钻头两刃不易磨的对称，钻头横刃修磨质量不易保证，而且刀杆刚性差，所以加工时易发生振动，孔的中心线易产生偏斜，由于钻头容屑空间有限，为了排屑和冷却刀具，必须在加工一段长度后(一般5~10 mm)即把钻头退出。

 

Because of the large axial force cutting drill, drill edged symmetry is not easy to wear, chisel edge grinding quality can not be guaranteed, and the cutter bar with poor rigidity, so processing is easy to vibrate, the center line of the hole is easy to produce deviation, due to limited space in order to drill chip, chip removal and cooling tool, must be in processing a length (5~10 mm) is a bit out of.

 

对于轴心孔较长的主轴，要采用从两端钻孔的方式。因此这种深孔加工方法质量差，生产率低、劳动强度大，但由于其刀具制造简单，可使用通用设备，因此在单件小批量生产中应用较多。

 

For the spindle with longer spindle angles, the drilling method is used at both ends. Therefore, the deep hole processing method has poor quality, low productivity and high labor intensity, but because of the simple manufacture of the cutting tool and the use of universal equipment, the utility model can be used more in single piece and small batch production.

2、套料刀加工深孔。孔径较大的深孔(一般直径大于50mm)宜采用套料刀加工。这种方法切削负荷减轻，从而提高了生产率，减少了材料消耗。所用套料刀，当直径较小时，多采用整体焊接式，直径较大时，可采用装配式或可调式。

 

2, the material knife processing deep hole. Larger hole diameter (general diameter greater than 50mm) should be processed with a knife set. This method reduces the cutting load, thereby increasing productivity and reducing material consumption. When the diameter of the utility model is small, the integral welding type is adopted; when the diameter is large, the assembly type or the adjustable type can be adopted.

 

刀具上应装置用于导向的耐磨镶条，其材料可为夹布胶木、硬质合金、滚动轴承等，刀刃设计上亦应考虑分屑和断屑。它也适合于批量生产。

 

The tool should be used to wear strip guiding device, the material can be textolite, hard alloy, rolling bearing, blade design should also consider the chip and chip breaking. It is also suitable for mass production.

 

3、采用深孔钻在专用深孔钻床上加工。采用深孔钻加工深孔较好的解决了深孔加工中刀具引偏、刀具冷却和断屑排屑等问题，明显地提高了加工质量和生产率。

 

3. Use deep hole drilling on special deep hole drilling machine. Deep hole drilling is a better way to solve such problems as offset of tools, cooling of cutting tools and chip removal in deep hole machining, which obviously improves machining quality and productivity.

 

可加工到10~30 的深孔。深孔加工机床，可采用专用的深孔钻床，也可对普通车床进行改装。

 

Deep hole capable of processing to 10~30. Deep hole machining machine tool can use special deep hole drilling machine, also can be converted to ordinary lathe.
