●Suitable for deep hole/deep cavity milling of parts.
●Adopt integral structure, connect rigid foot, high precision.
●The length-diameter ratio of the tool rod can be up to 10 times the diameter.
●The damping damping mechanism with“Real-time response” inside can make the cutting tool to process efficiently and simulate the vibration of cutting tool.
●Different machining range can be realized by changing different tool holders.

Shanxi Houma XX Company
Project background:
With Jig Company, complete program of semi-finish machining of 6-cylinder engine cylinder block. The project is strict to the whole processing rhythm, requiring high processing efficiency and low cost.
1.Processing content: cylinder block-12-thrust shield rough and fine milling
●Materials: HT300
●Machine tool: Mori Fine Machine horizontal add (BT50)
●Cooling: internal cooling, emulsion
●Cutter diameter Φ250, B axis rotation, left and right sides milling
●Process requirements: width 38 ± 0.1 mm, span 120 mm, roughness RA3.2
●Processing parts: milling left and right sides of the edge of a total of eight files (such as the red box on the right)
●Intermittent processing
●Higher processing efficiency is required to meet the process rhythm
