hy, i had been through this, with a new machine, and, even if the wipers were slim, the big cost come from shipping, etc
i can't sugest a source close to you, but, if possible, dismount, clean and inspect them, then mount back, gently pressing them against the covers; if some wipers seem pretty weared, switch them with ones from others machine areas, because, most wear appears on the lower z- side, while others remain in shape for longer
newer machines have an extra sheet metal, designed to protect them from chips
i have installed also a coolant valve, right in the upper left corner, that always washes away the chips, and the 2nd valve right above the chuck; if your pump has enough pressure, you may 'fork/divide' you actual coolant hose
on big lathes, thus with big covers, wear and scratches can appear fast, because the covers are heavy, and so there will create uneven distances between them and the wipers; even if you replace them, sometimes the source of scratch is within the 'heavy' weigth/buckling of tall covers, that allows chips to enter, thus, a new set of wipers, may be subject to real fast wear
so, if you wish, dismount, clean, mount back, and check that, on the other side of the cabinet, the cover comes clean, without chips; from time to time, i inspect that area, and clean the swarf, but in most cases it is only dirty, not with big chips / kindly
