YG cutters have specific e/mills for harder materials I followed their recommendations and dropped cycle time from 45 min. to 22 min. on a part that was rockwell 55. I did use a lot of tools thow.Still the drop in cycle time payed for the cutters and I was done sooner than had alotted for...
I have recently started a machine shop and have a job cutting 4340 its condition is E4.forgive me but I gave up machining for the last six years.Im back but forgot lots.Where do I go to find out what condition this is.Specifically how hard is it.Sure would hate to burn up inserts and...
master-cam offers a great cam package at a reasonable price.I have used it for many years, and I have found nothing for the same money that gives me as much control over the tool path.There are much easier and cheaper
packages out there but you will find later on when you get into some tricky...
Hands down mori seiki is the best.It is too bad that they are not from home.But if you want accuracy rigidity speed and reliability you can not beat them.Their resale value is the best in the buisness.They last forever and they hog.Ive been machining for 12 years and I have been around a lot of...
MORI-SEIKI.Ive been machining for years and hands down they are the best CNC machine for the money.They last forever and they will take more punishment( depth of cuts and feeds)than any other machine out there.Ive cut on most popular machines and nothing compares for the money.Ive done contract...
What is the feed rate and depth of cut that you are trying to use now?It has been awhile since I've cut any of it.If I am not mistaken They are very gummy materials.If you are using high speed steel toolingtry surface speeds of 100,carbide 350,coated carbide 900,cermet 1300, ceramic 2500.I...
The speeds and feeds you want are not able to be calculated from the info. you've given.The correct speed is calculated from the diameter of the cutter and the feed is calculated by the number of flutes on the cutter.although the way to calculate feeds and speeds is as follows.3.82*surface feed...
Cobalt with the TCIN coating is the best answer,carbide will catch a chip and break,although carbide will drill the hole much straighter.If I understand correctly your roughly drilling a .020in hole.By calculating feed and speeds you theoreticly should turn your spindle approximatley 9,703RPM...
Some of these ideas are good,but they seem costly.If your not doing large production spending money on expensive clamps is not the answer.Build a slip fit bushing(7.5O.D.x7.005I.D.x1.75 long) to set on the outside Dia. of the work peice.Cross drill three (120.deg equally spaced)set...
