316 stainless steel turning wear and shaving

[daniele1769]

good morning to all are daniele I would need some advice on turning stainless steel 316 I am working a bar d24 with a turning 45 mm long I owe depth 6mm diametrali then drilled d14 passing and a baren diagonal 18 long starting from d18 to d 14 for the hole I found a tip to insert d14 excellent work to 1600giri advance 0.1 and goes from god the turning I have an over job

many parameters but few useful and mal contextualized info.
type of tool for grinding?
type of roughing insert?
type of tool for finishing?
type of insert for finishing?
What kind of wear?
use of refrigerant?
past depths of roughing?
depth 'finish steps?

wear during roughing?
why speed on external processing less than the internal one?

on the site of insert suppliers there are always all the ideal parameters for machining. See you sandvik For example

grazie per le info

of course we do not forget degree of finish.

0.06mm seems to me as little as advancement, this could burn the tip if not properly refrigerated.
but, however, according to the insert used, which must be different between roughing and finishing and conducive to processing, the other parameters are defined according to the directives of the manufacturer.
if instead you use tools with insert reported and sharp individually, even with sharpeners, the speech radically changes

these cutting values coming out with the sandvik tool. https://www.sandvik.coromant.com/it-it/products/pages/toolguide.aspxas you see the advance is far from what you choose while putting a push finish; can not be seen but the rotation speed is 2300 1/min

first ask the tool shop that sells plaques and tools.

Let's hope you tell us what was wrong. just to get out of curiosity.

certainly the knowledge is unclear.
if it is a manual turning machine must have tables indicating the parameters to be used for material and processing; not that it is to be put with the calculator to make calculations of turns and advancement because it is enough a few months to acquire a sufficient sensitivity to manage the most common materials, but if something does not come back as in this case you must have tools to adjust the shot.
if it is a programmer must absolutely have technical data of tool suppliers to set the correct values; paper, calculators, excel tables, websites, certainly not missing the material
if we are still at the tools in hss or in widia balancebrasato hand sharp with angle of strip made to eye, then the only thing that saves the butts is the experience... a lot of experience and tools thrown into the bin

0.05 mm high for tips, I solved the problems with mitsubuishi plaques for bare ccmt21.51 r0.4 with roughing turns 1400 progress 0.08 removal 1.5 mm at a pass and a 1700 rpm finish with a 0.1 mm high-speed rig reduced to 0 and rough finish 1.6 cm
thanks for the advice and I wish you a good day
