Ceramic or cermet cutting tools may work for you but your machine, your tool holder and and your work setup must be very rigid. If you do use ceramic tools, do NOT use coolant. Note that while...
You're on the right track; drill undersize first then finish with an endmill. If you still have a chipping problem use an endmill with a corner radius of about 0.015", but predrilling should solve...
As thick walled as the material is, the boring bar setup is the most likely culprit. Use the largest diameter bar your machine and the part can accommodate, use minimum hang-out of the bar, use the...
I agree with Jim Dawson. If a part function wouldn't be compromised by having the radius, you're better off with the radiused tools. Also, cutting a small radius in the bottom of shaft key seats of...
It may be the control and not the machine. If the position feedback gain, particularly the differential portion of the gain loop, drifted higher than the factory setting, the oscillations you...
You're probably getting all of the tool life you can under the your current operating parameters, though increasing cutting speed a few percent might help a little bit. You specified the spindle...
I don't know what sort of work holding setup you have, and you didn't specify the direction and amount of offset, so I'm kind of shooting from the hip here. A setup with a spring loaded retractable...
Determining the sources of chatter can be quite difficult. A few things that are often overlooked are tool tip height, how well the boring bar fits the adapter, how well the adapter fits the tool...
You didn't say what sort of load the SSRs are supplying. An inductive load such as a motor or the coil of an electromechanical relay generates a voltage kick-back when power is removed from it, and...
In my experience on a large number of different machine tool brands, the pattern spacing of a well tuned machine in very good condition is always equal to the ball screw lead, and cutting speed and...
The insert is probably OK. Full annealing of the material can help a lot. If you can't do that, you can use straight infeed on the threading tool for the heavier passes and switch to 29.5° infeed...
It takes longer for the slides of a machine to accelerate to the programmed IPR feed rate as spindle speed is increased, thus producing a position lag relative to a thread if you make a pass at one...
