BIG DAISHOWA introduces the Mega Perfect Grip, a simple to handle, heavy-duty milling chuck for heat resistant super alloys (HRSA) that eliminates end mill pullout under heavy torque loads.

The importance of meticulously prepping, starting, and finishing holes can’t be emphasized enough.

When that inevitable job arises that requires higher RPM output, operators are left with the choice of replacing the machine altogether to gain higher productivity, or looking into an attachment, like a spindle speeder, to close the RPM gap.

Insufficient retention force of the spindle clamping mechanism could lead to reduced rigidity and vibrations, loss of machining quality, poor surface finish and shortened tool life. To help solve this problem, we have developed Dyna Force, a device for measuring the retention force of machine tool spindles.

Good measurements make setups faster, reduce recuts and identify potential spindle or holder issues before they become bigger problems. Let’s look at a few of the key areas to measure and the handy solutions available.  

For manufacturers using milling chucks, pullout is a major issue, particularly when machining HRSA’s such as titanium or inconel.

The return on investment from digital boring comes from the time saved making adjustments on the spindle, as well as the increased adjustment accuracy.
