I am looking for a piece of advice, I am planning to buy a CNC milling machine which has a ISO 30 spindle.
1. From Where Can I get a fine boring bar capable of boring dia 155 mm & has ISO 30 taper shank.
2. Is it advisable to use a fine boring bar for boring Dia 155 mm, in a iso 30 spindle.The tolerance on dia of bore is H7. How can I make it.
3. Do I necessarily need ISO 40 spindle for boring any dia in excess of 150 mm. some one told me that it is not advisable to machine a dia as large as 150 mm using iso30 spindle.
