  • show us your chip guard

    I was turning down some 8620 tonight, and a 2″ long helix flew over my head, and landed on the back of my neck. After a quick “hot hot” dance, and a bandage I was back to making chips. To add insult to injury I took a blue 9 to the chin 5 minutes later.

    Thus it's time to make a chip guard and I'm open to ideas, so show me what you got.

    It works just fine (the lexan box) but it makes it a pain to brush away chips or apply coolant-cutting oil. I don't use it very often.

      I don't use one.
      They are a PIA. they inhibit visibility because they are either scratched or dirty. Always in the way as well.
      I usually stand off to one side, out of the main path of 80% of the chips. I sometimes also wear a ball cap back wards (yeah, I know I know ) to keep those fliers out of my neck. I always wear safety glasses and if I have to get down close and personal, I'll wear a wrap around safety shield, as I have had a few hot ones sneak past the glasses.
      On the mill, and occasionally on the lathe as well, I'll use a piece of cardboard to deflect the majority of the incoming flak.

          OK,

          An hour of Google images, and a cup of tea latter, I'm starting to get a better idea of whats needed. What do you guys think about something like this?



          I would scrap the idea of bolting it to the compound, instead I would use some rare earth magnets to hold it fast to the qctp tool holders.

          Even,

          Can lexan be heated and bent at home?

          Mark,
          want to trade lathes, I have an 8x14 ?

            "took a blue 9 to the chin"

            Oh man, that's a great one. LOL

            Here's my chip guard. It does have limits, and it interferes with vision somewhat, though still better than working with my eyes closed.

              Yes. To avoid making a mess of it the polycarbonate must first be dried at low heat for an amount of time determined by the thickness. Polycarbonate contains trapped water and if heated for bending without drying first it will form thousands of tiny permanent bubbles that make it hard to see through.

              Drying temperature is 250F for 3 to 5 hours.

                I use lexan with gaffer tape hinges. The middle piece is held to the mill vice with magnets. I then have a front piece cut to sit on the mill vice or I sometimes hold it like a ping pong paddle. This system works great for the mill. I just use the handheld paddle on the lathe but would like to have something better.

                It is true, there is nothing free about freedom, don't be so quick to give it away.

                  I wear a flip down shield/visor. Works alot better than safety glasses IMO, since the safety glasses to fit over prescription glasses are a PITA. Still get the ones hitting the hands though. Some of them are hot!

                  Somebody posted a pic a while back of a flip down shield for their lathe chuck made out of one of these safety shields. Can't remember if it was on this forum or not. Thought it looked like a good idea.

                    I purchased a magnetic base with one of the "snake" arms but found it didn't work well for holding an indicator so I use it to hold a chip shield.



                    I used a piece of Lexan I found but it needs to be cut down, it's larger than needed and is heavy enough so it is a challenge for the arm to keep it in position. Its best feature is that it is easily moved from machine to machine as needed.

                    The bits of plastic around the mill table are for swarf containment. I had a 3 sided plastic box around the table but it didn't work out after adding the DRO because of the way I attached the Z axis.

                    I'm hoping this thread will have some ideas for a plastic chip deflector that partially surrounds the tool and is easily moved out of the way, something perhaps 4"-6" diameter. My goal is to confine most of the swarf to the mill table to simplify cleanup.

                      For a smallmill maybe youcould use a soda bottle wiht the neck cut off (Sherline)

                      If you get brass in your eyes, use a peiece of shim stock, over the tool in the T.P which might a lso work for a chip breaker.


                      For a small lathe there is a very professional looking one, wraparound, made of face shield on a Griz mini lathe. Looks like commmercial accesory.

                        I use a chunk of plexi cemented to a chunk of acrylic tube, slipped over the shaft on a mag base. easy to move, easy to spin out of the way for fast access.

                          Two simple ones

                          For the mill, a fitting that plugs in near the quill, and supports the chip guard on a stalk of Loc-Line:



                          For the lathe, one that fits into a magnetic base indicator holder:

                          Cheers,

                            I do the same with a generic noga indicator mag works great and is easily removed
