When repairing a damaged flange face using a portable machine tool you want to get the job done as quickly as possible while maintaining the workshop quality tolerances that on-site machining can provide.

Double check your machine installation

It’s not a revelation to hear that you need to set your machine up properly in order to get a true and even surface finish but it’s worth stressing anyway. One of the most faults when diagnosing a poor surface finish is the incorrect set-up of the machine.

Keep an eye out for the following oversights:

  • Check the balance of the machine.
  • Ensure installation bolts have been tightened
  • Double check the machine base has been installed correctly.

Use the right cutting tip

The surface finish that you require will dictate which cutting tip you should use to achieve that surface finish. The cutting tip can often be overlooked when setting up the machine and if the wrong cutting tip has been left in the machine, you will end up with a poor finish.

For quick reference, you should use the follow cutting tools for each surface finish:

  • Stock finish - round nosed tool
  • Smooth finish – round nosed tool
  • Cold water finish – high speed machining with wide tool
  • Spiral serrated – 90 degree tool
  • Concentric serrated – 90 degree tool

Check your feeds and speeds

Each surface finish type requires a different feed rate. If you find your surface finishes are wavy, rough or inconsistent, you will want to check that you are using the right feed rates.

For a detailed breakdown of the feed rates you should refer to the machine’s manual or visit our feed rate and speed calculations blog post.

Maintain your machine correctly

As manufacturers of high-quality portable machine tools we know what it takes to get workshop quality finishes when carrying out on-site machining operations. The most critical part of the whole process is having a machine capable of carry out the operation and a poorly maintained machine will not fit the bill.

We recommend that a maintenance schedule that includes specific tasks be performed after every use as well as implementing a general maintenance schedule after every 10 hours and 100 hours of use.

For a more detailed explanation of the maintenance schedule that we recommend, refer to your machine manual.
