Hello all,
I'm new to this forum and coming to the forum with a crucial issue to our shop (desperate). We are going through Guhring mill / drills at an alarming rate. I have inherited this process and it has always been known to be a tool breaker, but it is at a serious point where we need to look at cost savings. Since start of production this year we have consumed 720 drill bits at a cost of $38,000 and 320 end mills at a cost of $5,500.
It is an outer race with a spline. Two oil holes are milled and drilled into this outer race from the spline side. The material is SAE 1060 Rockwell C 26-36
This operation runs 1,900 parts per shift, 2 shifts a day, 5 days per week. There are 3 robodrills that perform this operation 2x per part. Based off of that, each machine performs each operation 1,267 times per shift.
The operation is appears to be a 2mm depth of cut with a 2mm mill to form a pilot and then a 2mm drill operation thru cut which appears to be about 6mm in travel.
Machine: Fanuc Robodrill Alpha-T14iE
Operation 1: Carbide Mill 2.0mm Guhring 16,000rpm at 190 mm/min 2mm depth of cut Guhring
Operation 2: Carbide Drill 2.0mm Guhring 14,000rpm at 720mm/min 6-8mm thru cut Guhring
Does anyone think this existing tool can be saved with feeds/speeds or if I should pursue a different tooling supplier?
