How To Cut External Threading Time While Maintaining Precise Quality

When it comes to external threading, it can be a time- and labor-intensive process that requires specific expertise if it is going to be done correctly on a consistent basis. Cutting external threads by hand is tough work, especially with the tolerances being so tight. And while using the lathe is a solution that is becoming more and more popular, it requires the right tool and the right program—not to mention the right guy to run the machine. But what if I told you that a solution existed that made external threading a walk in the park?

4 Ways a FlexArm Solution Makes External Threading a Walk in the Park

  1. Quickness – You know what they say, time is money. With our Quick Change Die Holders, you’ll be external threading in no time. Setup time is significantly decreased as well, especially compared to threading on the lathe, as there is no programming required with the FlexArm.
  2. It’s More Ergonomic – Nobody is doubting your ability to create external threads by hand, but why put your body through extended forceful exertions if it doesn’t have to? With a FlexArm solution, the machine does the work—and more precisely, too.
  3. Precise Depth Accuracy – Whether it’s one of our digital depth control options on a hydraulic arm or the mechanical system on a pneumatic unit, you’ll be able to maintain consistent depth accuracy each and every time.
  4. Guaranteed Perpendicularity – Eliminate scrapped parts and wasted time. With the FlexArm solution for external threading, perpendicularity is guaranteed every time thanks to the design of the arm.

Let us know how we can help your shop become more efficient when it comes to external threading. The FlexArm solution will not only improving cycle time but also increase quality control as well. Contact us today for more information on the wide range of solutions FlexArm can provide for you.

    I have been looking for an external threading tool. Do you sell the die holder separately?

    Thanks!

Auto Stand-Off – This is currently defined to be surface stand-off and not to be confused with vector stand-off in 5-axis mode. The current auto stand-off is based on a changing surface and will adjust vertically based on the angle of the “A” Axis, so there is five (5) axis taken into account during the calculations, but this is not the same as the tool vector stand-off. There is the ability to do the vector stand-off change while the machine is running manually with buttons on the screen.

Z-Reader Probe – The Z-Reader is a device for mapping the location of the surface. It can be controlled manually & programmatically. The option is NOT active while cutting & is retracted out of harm’s way. It can be triggered to verify the surface at every pierce before the cutting process starts, or it could be used to drive surface mapping of the whole part before cutting starts. It begins with initialization or zeroing of the device to the surface at the beginning of a program and then accumulates or tracks the difference from that zeroing effort.

Automatic Edge Finder – The edge finder is or can be utilized manually (Jogging Method & Screen Buttons), programmatically (M & G codes), or fully automatic routine (dedicated program). This option sets offsets & program rotation to match the orientation & location on the cutting table.

AC Unit Installed on Electrical Cabinet – The unit is mounted on the cabinet’s High Power (480v) side. It is close to the location where the drives are mounted. This option keeps the cabinet temperature stable and allows heat dissipation faster. The servo drives for all axes are the most significant contributors to heat inside the electrical cabinet.

5-Axis Renishaw CalibrationThe calibration unit is a Renishaw model APCA45 with a modified spherical stylus. The device has a retractable cover and air purge to clear debris & dust during the activation process. It mounts to a swing arm controlled by a pneumatic rotary, so it is out of the way during regular operation and swings into the calibration position for calibration only.
