Technical description
1.High accuracy&efficiency
High speed direct drive motorized spindle,rotating speed up to 30000r/min,combining with our flexible feed technology,makes efficiency of tyre mold drilling increased more than 4 times,and the qualified rate of drilling is more than 99.99%.The drill bit breakage rate is less than 0.001%,which greatly promotes the technical lecel and quality of vent hole manufacturing.
2.Expert system
MLT-Z228t CNC system,with many unique MLTOR deep hole drilling technology inside,such as expert process database,online vibration monitoring,drill-break protection,power-off memory,etc.
3.Easy operation
Friendly man-machine interaction interface,easy to operate,only a simple training can be skilled.Improve woke efficiency,reduce training costs and reduce human intervention.
4.High intelligence
It integrates the functions of hydraulic pressure,oil cooling,filtration,chip removal and oil mist purification.The processing process is highly automated and practical.At present,the whole process of unattended processing is achieved.
5.TBT gun drill bit
Using TBT gun drill bits that customized for MLTOR machines,makes our efficiency much higher and extend the tool life.
6.Strong capability
Can process vent hole of the two-piece molds,segmented molds,sidewall plate and bead ring,as well as the direct vent holes with very small aperture.The innovative L-shape bad design with back side drilling can realized the interference angle drilling which can note be processed by traditional internal drilling method.
