Complete interpretation of quality drill bits second development

CNC deep hole drilling ( gun drill ) in recent years developed a deep hole

machining new technology. The traditional deep GUSHI circular blades  hole machining ( hole depth

and aperture ratio greater than 5 ) , requires drilling, boring , thick

hinges , grinding , and other procedures in order to process a higher

accuracy and lower surface roughness of the hole . The new technology is

the use of special tools and high-pressure structure of cooling and

lubrication systems , multi-channel processes described above can be

simplified to a considerable depth consecutive passes completed high

precision and low surface roughness of hole machining , high efficiency of

this process , significant economic benefits .
Excellent performance cutting fluid deep hole drilling deep hole drilling

process is one of the key technologies , deep GUSHI carbide drill bits  hole drilling cutting fluid

must have the following properties:
1 ) good cooling effect, eliminating the heat generated due to the

deformation and friction , inhibiting BUE formation.
2 ) Good high temperature lubrication, reducing friction and wear blade

and support to ensure the tool to maintain good lubrication at high

temperature cutting zone .
3 ) good permeability , chip , so that timely cutting fluid penetration

into the blade, and to ensure the smooth chip discharge . Thus , deep hole

drilling cutting fluid requires a high extreme pressure and low viscosity.
Mechanical products, styling products series occupies a large proportion .

Mostly the same series of styling products have the same or similar

contour features in traditional modeling methods for product design,

inevitably the model geometry the size and shape of the structure

repeatedly modified , adjusted and optimized , low design efficiency. In

order to improve design efficiency , styling products for serialization ,

you can use the parametric design method . Parametric design is the use of

a set of parameters to constrain the geometry of the product model , in

order to facilitate the realization of the variability of the product

model , design reusability and fast it can shorten the  GUSHI brick saws design and

development cycle and improve design efficiency , freeing the designer

from the tedious modeling work, put more energy into the model analysis ,

and improvement of innovative work, for subsequent finite element analysis

and formulation process ready to work .
The most widely used in the drilling of the twist styling products also

belong to the series , the same type of high-quality twist drill has

structural features are similar , but differ in terms of size parameters.

Based on high-quality drill design software , call the API target for

secondary development to achieve the parametric modeling of complex

spatial design twist front surface flank , flank , flutes and cutting edge

belt.
