5 Gifts from Us to You
First and foremost, Happy Holidays from the whole BIG KAISER team. We wish you and yours health, safety and fun during this exciting time of year.
Hopefully you are able to enjoy a much-deserved break at some point. After all, this work you do is tough. Every day brings a new material, a funny entry angle, a rogue chip or another tight work envelope—situations that may require any number of unique tooling solutions and extra care to get the job done.
So when we got to thinking about ways to give back this season, we thought we’d try to help make your life a little easier by highlighting some of the most impactful tips we’ve shared over 2015. Between all the magazine articles and blog posts, there’s quite a bit to choose from, but here are five that stand out.
- Heat behaves differently in micro machining
Since the chips micro tools generate are naturally smaller, less heat is transferred to them resulting in less displacement from the tool and cut. In addition to an oil/air mist to help accelerate cooling and chip removal, consider using a machine with fine servo control to peck the hole and fully retract the drill, especially in high length-to-diameter ratio cuts.

- Proper coolant use in small-diameter rough boring
Use center-through coolant when possible, especially in blind holes to aid chip evacuation. If using external coolant supply, the cutting speed needs to be reduced.

- Insert selection in deep-hole boring
The ideal insert selection is going to be a ground insert that has a sharp cutting edge to cut more freely. This not only helps reduce the tool pressure, but ensures that the chips remain short and can be effectively evacuated from the bore—a critical requirement to maintain size and finish control.

- Inspection of pull studs
This one bolt must stand up to severe conditions, and should be inspected and exchanged regularly to ensure top performance and integrity. Repeated clamping and unclamping during automatic tool changes leads to pull stud bolt fatigue, and can cause breakage. Generally speaking, a pull stud bolt has about a three-year life span, but this can be much shorter depending on tool change frequency and many other operating conditions.

- Selecting a presetter
You’ll want your presetter to come out of the box capable of measuring the maximum length and diameter of the tooling you use or could even use in the future. It should also measure in increments that match your tightest job tolerance. And of course, make sure it pairs with the spindle type from which you’ll be measuring, or has the ability to utilize adapters.
