3. Cutting test method The test device used in this test is shown in Figure 1. The compressed gas produced by the compressor is sent to the cold air generating device, and the instrument and switch are adjusted to the required temperature, and then sprayed by the nozzle between the rake face of the tool and the chip. This acts as a chip evacuation and cooling cutting zone. In sub-dry cutting, the additive is dripped with the cold wind between the rake face and the chip. In this study, continuous cutting was used as the research object. All the same materials and the same type of test were completed on the same test piece; the same material was used in the cutting stability test. Segmented continuous cutting is done to increase the comparability of similar tests. 4. Test content When cutting GCr12, take ap=0.75mm, f=0.1mm/r, and get Figure 2. 1. Natural cooling 2 Air cooling (-23 ° C) 3. Burning cooling Fig. 2 Relationship between heat cut and cutting speed of three cooling methods when cutting GCr12 When cutting GCr12. Take V=49m/min, f=0.15mm/r, and get Figure 3. 1. Natural cooling 2 Air cooling (-23 ° C) 3. Burning cooling Figure 3 Comparison of cutting forces for three cooling methods when cutting GC12 When cutting Cr12, take V=51m/min, ap=0.75mm, f=0.1mm/r, and get Figure 4. 1. Natural cooling 2. Pouring cooling 3. Air cooling (-23 ° C) 4. Sub-dry Fig. 4 Comparison of cutting heat between different cooling methods when cutting Cr12 Previous Next
H Ground Screws also called Screw Piles in some countries and it means Ground Screw Piles with helical blades. There are kinds of Ground Screw piles on our ground screw factory. The first type of Screw Pile is Ground Screw Pile with one helical blade, the second type of screw pile is ground screw pile with two pieces helical blades, the third one is screw piles with three pieces helical blades. But ground screw piles one piece helical blade is very popular with our customers because the friction with the ground is more than other types and many customers like this type of ground screw piles. Ground screw with helical blades can be used to Solar Ground Mounting System, garden decorations, farming fixing and so on.
Ground screw pile made in China and as one of producer of ground screw pile, we will recommend you two types of screw piles as your reference. One is about ground screw pile with one piece helix blade and another is about ground screw pile with two pieces helix blades, which both can be used to solar panel structures. As one type of solar screw piles, is very hot product on Finland and Thailand. It also be installed to the ground by Pile Driver as the support of solar panels or solar mounting systems. Screw piles as the related solar energy products are very hot sale products and they are very stable as supporting.
Some types of ground screw we exported can be used to construction field. Ground Screw with Nuts and Ground Screw with Flange, both types of ground screw will be installed if you want to use ground screw in construction field. We produce diameter 114mm-335mm of ground screw and length 1600-4500mm as your choose if you would like to purchase ground screw using to kinds of buildings. If you need these Ground Screw Anchors , please let us know, we will do some plans for you according to your requirements. In addition, Hot dipped Galvanized Ground Screw can not easy to be rust and it can be keep more than 25 years and the material of construction ground screw is Q235/Q235B/Q345 as your need.
