Blue Flag Mold Roughing Layered Milling Tool Twincut-Vario
The use of diamond cord core drill bits must be done step by step according to the requirements of the onion, not to be rushed, and the drill tool assembly, deployment, and maintenance must be done well.

The unique feature of this tool is the design of the tool body. The tools we have seen on the market, after the blade is mounted, the blade height is on the same plane, and the tool is installed next to the two blades. Not at the same level. Therefore, the two adjacent blades are not cutting the front and rear materials on the same level, but the upper and lower materials at the same level. This is called layered milling. As shown in FIG: 
1, the most obvious is that the power of the machine tool has dropped. According to research, compared with the ordinary beef nose knife, the machine power is reduced by nearly 30%, which makes some old machines with insufficient power regain their youth; 2, low noise Compared with the ordinary beef nose knife, the cutting resistance is small, the friction is small, and the noise is naturally small. 3. High-efficiency cutting can bear a greater depth of cut than a normal beef nose knife; 4. It is especially suitable for cutting. Poorly rigid machining conditions, such as large overhang machining; 5, the offset design of the blade allows the tool to have better dynamic milling performance, increased blade strength, optimized chip and better plunging angle. The tool has a diameter ranging from 36mm to 125mm. There are two types of blades for this tool, R8 round blade and 8-corner blade, as shown below: 
The circular blade can be used for plane roughing, cavity roughing, profiling, etc.; after the octagonal blade is mounted, the main declination is 45 degrees, which is especially suitable for ordinary plane roughing. It is worth mentioning that the R8 round blade of the blue flag and the octagonal blade of the circumscribed diameter of 16 each contain a PVD two-color coated LC280TT roughing blade. The upper surface of the material blade is black AL2 PLUS coating, and the periphery is golden yellow. The TiN coating makes it easy to observe the wear of the blade. This material allows high speed and high feed machining. The LC280TT material is suitable for the following situations: 1. Any cutting edge is prone to chipping; 2, under difficult cutting conditions, such as interrupted cutting; 3. Mounted on ISO tool body (RDKT insert). 
In the case of extremely poor rigidity, we have a processing example: the processing material is ductile iron 400, the selected tool is Twincut-vario with a diameter of 50mm, a total of 6 blades, the blade type is RCKX 1606MO-TR LC610T, this blade material Designed specifically for cast iron machining, the specific cutting parameters are as follows:
Vc=200m/min
n=1000 rpm
Fz=0.25/z
Vf=1500mm/min
Ae=43mm
Ap=3mm
The cutting process is smooth, and there is almost no vibration due to poor clamping rigidity.
Twincut-Vario has been welcomed by the users with its unique design and efficient processing efficiency, but domestic users are not very familiar with this tool. At present, there are some stocks in the Lanzhi Nanjing head office and Hangzhou office, if the user Need, we will provide you with fast, high quality service.
The characteristics of rope core drill pipe are "three highs and one low", that is, high drilling speed, long life of diamond bit, high time utilization rate, low labor intensity of workers, so it is widely used in geological prospecting, coal field exploration and other fields. Among the whole set of drilling tools, the most important and most valuable is the drill pipe. The quality of the drill pipe is directly related to the use of the advantages of rope core drilling, and is also vital to the accurate acquisition of geological data and the control of drilling costs.
