Optimize coatings to help the tool improve competitiveness

The quality of the coating plays a crucial role in the production of the tool. Only by considering all the factors in the design and production of the tool, such as the geometry of the tool and the application conditions, can the overall competitiveness of the enterprise be improved.

It is worth noting that at present, although coating plays a vital role in the production of tools, how the performance of the coating, how the coating is applied to a specific field, or how to compensate for the shape of the tool is not sufficient to improve the performance of the tool. I still know very little about knowledge. Through years of production practice and experience, it can be concluded that only by considering all the factors in the design and production of the tool, the producer can produce a successful product.

At present, it is still widely believed that the tool coating can extend the service life of the tool. However, can the degree of wear of the tool be the only criterion for judging the quality of the tool coating? As can be seen from Figure 1, the answer is no. For the TiN coated tool with geometry (A), no significant improvement is seen. By changing the orthogonal slope of the tool by 1 (B) and changing the size of the clearance, it is easy to see that the service life of the tool is significantly prolonged.

Fig. 1 Effect of the geometry of the cutting tool on the wear of the HSS tool: geometry A: S=6, μ=5, geometry B: S=5, μ=6; Vc=67 m/min, f=0.25 mm, Ap=2.5mm

This example shows that the tool geometry and coating have complex interdependencies. Another factor that affects performance is the cutting speed. The benefits of coatings can only become apparent under the conditions of accelerated cutting speeds and consequent superb cutting loads including high temperature thermal stresses. Therefore, successful and economical tools can only be developed if the same attention is paid to the geometry of the tool, the base material, the coating and the application conditions. At the same time, the application of the coating will affect the formation of chips on the cutting edge. The friction and thermal physics of the coating will change the flow velocity, thickness and curvature of the chip. The presence of the coating reduces the amount of heat transferred to the tool. This fact leads to a great change in the temperature of the chip. For example, the application of a low thermal conductivity TiALN coating will directly affect the formation of chips and increase the temperature of the chips.

Liposuction Pump

The Peristaltic Pump can be used in liposuction surgery, in the process of swelling anesthesia, used to deliver saline.
The definition of swollen anesthesia is to infiltrate into subcutaneous adipose tissue by ultra-low concentration, high-dose, a large-volume local anesthetic (currently used lidocaine) as an anesthetic method for liposuction.
Swelling anesthesia was first proposed by Klein in 1987. It is also called [over-perfusion anesthesia". A large amount of solution containing adrenal and lidocaine is stably perfused into the skin through a peristaltic pump, causing edema and cell tissue gap in the subcutaneous tissue and its structure. The small blood vessels are separated and pressed to be locked, thereby achieving the effects of local anesthesia, pain relief, hemostasis, and tissue separation.

Swollen anesthesia can be used as separate local anesthesia or combined with general anesthesia or regional anesthesia.

The advantage of peristaltic pump in swelling anesthesia:
1, easy operated, non-contamination
2, foot pedal control ,safety & reliability
3, adjustable speed and left/right direction optional

4, Power-down memory function
