A manual Milling machine on its own can perform a variety of complex functions on a required workpiece. From carving to flattening or curving, it performs these processes with almost pinpoint precision. It would be pleasantly surprising to know that the already precise functioning of the Mill can be further enhanced using external influences and specialized tools.
This effect can be acquired by even adopting several design changes to the machine. Not to mention, the existing tools of the Mill can be upgraded to add to the overall efficiency of the Machine. While used manual milling machines are repurposed to last efficiently longer, imagine the boost that production will receive with the addition of upgraded add-on.
Without further ado, let’s browse through some of the tips to enhance the operations of the Manual milling machines.
- Apply the liberal use of Sine bars in setting up the angles. While being really simple to use, this tool is also deadly accurate. Manual mills require smaller and handy versions of the sine bar since they are meant to span the ways of the standard mill vise. Set vice and head angles easily with the bar. The process is much similar to how the head is trammed to set the precision angle.
- Indicators with Vertical dials are used to zeroing any part of the machine, instead of craning around the machine.
- When tramming the head, it is recommended to sweep a larger arc using many lengthy indicator holder bars. Check the condition of the head tram if there is any trouble getting to a bore which according to you should have been round. If there is no such problem, you will either see equal but mismatched numbers or a longer direction.
- During trimming, it is found that a button type indicator seems to slide more easily over the T-slots as compared to a test indicator.
- Special-toothed wedges serve as a better backstop since they snuggle firmly into a T-slot of any width. Their height can be changed accordingly and they also come handy for specific clamping jobs.
- Utilizing a first-class combination square on the mill will allow you to assess the precise flatness or reliably measure angles of the vises in the machine.
- Cutting the extra-long shanks off the drill chucks allows you to avoid regularly cranking the Knee to wedge out the chuck from the shank. Maybe consider losing the R-8 shank off the drill chuck, since the collet is just 1” long on the inside.
- Changing collets comes easy when you sensibly invest in a power drawbar. For one, you can happily avoid smashed and hurting fingers or working a wrench overhead regularly.
- During tricky setups, let your hand stay on the specific part since any slight shifting will generally be detected by your hand first and then your eyes. This will alert you to stop cranking the feed lever in your other hand.
- Gage pin application to set sine bars eliminates the build-up of errors. Additionally, using a caliper on a stack of blocks keeps you on the safe side and confirms your calculations.
These are simply some of the many tricky tips for enhancing the efficiency of your machine and providing a more relaxing vibe to the hectic trend of Milling. Hopefully, this will make work seem more interesting and intriguing from now on.
