hello,
we have new parts comming , basically permanent mold 356T6 aluminium rings and plates with plenty of face grooving for O- rings free of chatter and vibration with good surface finish .

The rings are of dia 365 to 400 mm and weigh about 7 kg and above.
We have the option of normal horizontal turning or VTL.

Any body can advice which will be the better choice.

thanks
