The main problem with the use of solid carbide end mills for profile milling of titanium alloy parts is the extremely high axial cutting forces that cause the tool to slowly come out. Even the most powerful conventional shank does not completely prevent this clamping force and accuracy from gradually decreasing.
In view of the high cost of raw materials and the time-consuming processing (about tens of hours) in the early stages of processing, manufacturers often only use conservative cutting parameters, so that they cannot fully utilize the potential of their tools and machine tools. Therefore, how to avoid the tool from the tool holder Disengagement has become a crucial requirement.
The iLock pin ensures that the tool is firmly positioned to prevent the tool from coming out
Sandvik Coromant's new clamping system with iLock locking provides a solution for CoroMill Plura solid carbide end mills with a spiral groove on the tool shank and matching in the chuck Pin the screwdriver. The pin secures the tool and makes it difficult to escape even under extreme conditions, as the cutting force only presses the tool tighter against the shank.
The biggest benefit of this tool holder innovation is the ability to triple the depth of cut. This obviously greatly increases production efficiency and has the potential to significantly reduce processing time.
Moreover, this system improves the typical runout accuracy of condensing chucks compared to the Weldon solution. This precision significantly increases tool life from
Further saving costs and increasing efficiency and productivity.
In addition, the new clamping solution has the third advantage - it increases the cutting speed and makes the stability and cutting parameters of titanium alloy processing even higher.
to sum up
Larger pulling force is a major problem in the vertical milling of titanium alloys. Innovative tool holder technology eliminates tool removal and increases depth of cut and jitter.
It is possible to speed up the cutting speed.
