That looks to be a knock off of the Oregon 511 or Tecomec grinder.
Sure looks like the same motor anyway, and the vice with the tilt is the same... Anyway...
Ok, for what it is worth, I think you are doing very well. A few things I would change:
It looks like you are sharpening .325 pitch chain. There is a 5/32 wheel available that is in the middle of the wheel sizes you have. That is the one that I am using on .325 chain. On my grinder, I fudge just a smirch and set the angle at about 58 deg instead of 60. I don't tell people this, I just do it. I also use 30 deg instead of the 25 you are set up at in the pic. One other thing, the vice can "tilt". This helps with making a nice corner as it mimics the 10 deg upward angle towards the corner of the tooth. Just tilt the vice so that the wing of the cutter is higher (right and left cutters are opposite tilt...).
Keep Thy grinding wheel CLEAN. This is the single most important pointer I can make with anybody grinding chain.
Never, and I mean NEVER allow a dirty wheel to "heat" the cutter. Really bad things happen then.
Take your time, go slow. The grinder has a little "play" by design, if you watch what you are doing you can make consistent cutters, each side might be a slightly different length. You can compensate for that with the distance pawl.
whip out a screwdriver and do a little investigating. Open up the power switch, and see if the connections are available to the start winding. IF so... do a search on here for Reversing the Oregon 511a. There is a schematic that I posted on how to do it. The results are well worth the effort. What you do is run the motor in reverse on the left hand cutters. Yes it will shoot sparks at you!!! sit off to the left side so you can watch what you are doing! This keeps the chrome edge CLEAN!!!
A good indication of things working RIGHT is when that little whisper of chrome shoots off at the end of grinding a tooth.
You can stick a 1/4 inch wheel on there, and stand the grinder up to 90 deg to do the depth gauges. File the first one on a bar to set the depth you want, then set the grinder to the same on that tooth, and run around the chain. Everything ends up nice and even, and WAY faster than hand filing all those gauges.
