Hi,
I am a small business owner in India, new to this forum, with no background education in machining/mechanical engg. Just plain 4 yrs of experience in manufacturing automobile parts (machining + fabrication).
I am using several indexable drills (we call them U-drills) of various sizes (17mm-22mm) on Turning centre/VMC. On Mild Steel and EN8(carbon steel, C-0.4 to 0.5) material. Maximum feed I have been able to achieve is 80-130mm/min, using RPMs of ranging from 1000 to 2100 and feeds of 0.05 to 0.08 max.
I have tried using Sandvik, Tungalow, Taegutec brands of tool holders and inserts, who all claim to be able to maintain feeds upto 0.15mm, but practically are not being achieved in my shop. Why this gap.
The only drawback of my machines is that they do not have provision for through coolant. Can this drawback be the cause of such drastic differences from what companies claim and what I can achieve.
