有關濟南手板模型深孔加工的3種方法：

 

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

 

1、接長柄麻花鉆在通用機床上加工。接長柄麻花鉆就是在普通麻花鉆上焊接長柄。

 

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.

 

由于鉆削時軸向力大，鉆頭兩刃不易磨的對稱，鉆頭橫刃修磨質量不易保證，而且刀桿剛性差，所以加工時易發(fā)生振動，孔的中心線易產(chǎn)生偏斜，由于鉆頭容屑空間有限，為了排屑和冷卻刀具，必須在加工一段長度后(一般5~10 mm)即把鉆頭退出。

 

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.

 

對于軸心孔較長的主軸，要采用從兩端鉆孔的方式。因此這種深孔加工方法質量差，生產(chǎn)率低、勞動強度大，但由于其刀具制造簡單，可使用通用設備，因此在單件小批量生產(chǎn)中應用較多。

 

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。孔徑較大的深孔(一般直徑大于50mm)宜采用套料刀加工。這種方法切削負荷減輕，從而提高了生產(chǎn)率，減少了材料消耗。所用套料刀，當直徑較小時，多采用整體焊接式，直徑較大時，可采用裝配式或可調式。

 

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.

 

刀具上應裝置用于導向的耐磨鑲條，其材料可為夾布膠木、硬質合金、滾動軸承等，刀刃設計上亦應考慮分屑和斷屑。它也適合于批量生產(chǎn)。

 

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、采用深孔鉆在專用深孔鉆床上加工。采用深孔鉆加工深孔較好的解決了深孔加工中刀具引偏、刀具冷卻和斷屑排屑等問題，明顯地提高了加工質量和生產(chǎn)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。深孔加工機床，可采用專用的深孔鉆床，也可對普通車床進行改裝。

 

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.
