- First of a two part video that looks at surface grinding. Surface grinding is not generally used by hobby machinists but learning the basics of the process can help to impress a future employer or bring someone to farm out certain operations to a specialized shop because they would understand that this technique could help in completing and important part. In this video, we will look at the basic cutting action of a grinding wheel, how to operate a manual surface grinder, wheel dressing and part preparation for first cut as well as speeds an feeds for grinding. This video is part of a series of videos that include:

As for all THATLAZYMACHINIST videos, this video is produced for novice , garage or beginner machinists. You can find all my videos as well as project drawings and course notes on my website THATLAZYMACHINIST.COM . Thanks for understanding that I am a professional toolmaker and teacher but I am not a professional video producer (and it shows). I produce these videos for fun as a little retirement project that lets me give back a little of what was passed on to me by so many amazing trades people most of whom, sadly, are no longer with us.

Have you ever ground anything for real ?? Lmao
Hi Tim, nice to hear from you again. Thanks for your support and for taking the time to write. How's Andrea? Has her condition improved? Paula and I are looking forward to seeing you both very soon. (Damn covid)
I have same question. Have you ever ground anything for real ?? I'm tool and die maker with over 40 years of experience . When I dress the will I never ever stop spindle . There is lot of experts on youtube but there is very few really experts.
I misspell Wheel but I'm just tool and die maker he he .
This was the first video on grinding I ever watched. I finally bought one and I'm so stoked! Thanks for lighting that fire!
Thanks again Marc you’re all ways so explained and I learned a lot
Great video.... Smashing chap teaching folk on here some very valuable information on surface grinding.
There's so much to learn with how to grind different materials, wheel selection, and a huge variety of attachments and various fixtures.
Jones and Shipman 540 surface grinders are the best .
Thank you, Marc for your great way of disseminating information
Probably the best videos on CZcams. Learned a lot. Huge thanks.
Great video. Thanks for making it! I like your presentation style. Information dense and no fluff.
I love the surface grinders man! I took a big liking to them while in technical school 3 years ago.
great video...just had a full day with my mentor (retired tool maker) Chui hours of setup and grinding discussions, looking forward to your videos
I have been wanting to get a used surface grinder for my garage shop for a long time now. The video was very informative and I look forward to part two.
Bonjour,
I admire the way you come back to explain your techniques . I am a fan of your art.
I spent my prime time around 7 years from college and afterwards in Montreal , what a great place. Watching your videos from great land of Australia now.
Another great explanation
Thanks for posting Marc!
Also, great video! very informative. I've just bought a small 612 manual surface grinder and am learning as much as possible while I finish prepping/installing the thing (cleaning, new fluids, 3-phase power accomodation, Fix/replace DRO etc..). This helps a lot with the basics. I really like your description of the various tool profiles and the chips they produce when the DOC gets small. Initial process is a bit like woodworking where we use a jointer to make the reference surface then the planer guarantees thickness.
Brilliant video,ive just bought a surface grinder and your knowledge will be very usefull to me.Thank you.
AWESOME VIDEO
Very instructive! Thanks
I can't wait to see the next one. This required multiple watches in sections for me to get some idea on what is going on.
Miss my old tool and die maker days. Spent 10 years grinding zipper die parts.
Very useful. Thanks.
Thank you Marc for the video! I like the background information that you give; it makes a big difference.
Looking forward to the next video. I bought a surface grinder last year and will be moving it soon and getting it running. While i did use one years ago, i have forgotten so much.
Thank you
This man is a genius
That's what I have been telling my wife and kids but for many reasons, they don't believe me. Thanks for watching and for your support, Marc.
Nice
you should make a video on " what do you need to watch or pay attention when you buy an used surface grinding"
I saw some, but wasn't sur what to look and test before buying it
Dear Marc, thank you very much
Lesson: 50
Funny thing happend we got a 10 foot bed surface grinder at work and im spose to figure it out. Itss goin just fine. Just fine. Anyone have advice?
Wbich grits are your burnishing and lapping plates?
How would you secure non-ferrous material to your table, or if it didn't have a magnet?
Please let us know how to open jammed surface grinding wheel and it will open in clocked Wise or anticlockwise
Would you believe i got a job grinding tools and one of 3 machines is a small light weight surface grinder. Watching utube i learned alot and only had 1slight accidents cause i for got to tighten the index spindle. Like you say light removal is only way to accurately re move material safely. Tomorrow morning i was asked to see if i can remove. 008 from a spacer used in a spindle just being rebuilt.Since the magnetic table is around 6" there will be over lap of the part im grinding and at 30 degrees will be a challenge depending on the y travel in relation to the spindle or grinding wheel. I haven't seen the part yet but i may have to rearrange the complete magnetic chuck @30"
Sir I m indian from India haryana
Can select same Rpm for both grinder and grinding disc is it safe
Can a norton wheel grinder be used to grind a engine head?
Is it just me or did you feed your part into the wheel on your backstroke a few times? Also a nono?
I noticed at the 6 min mark you only fed the table in one direction and then returned it back to where you started. Do you only grind in one direction?
Marc, the problem with videos like this is that now I'll have to go get a surface grinder. ;) I've watched grinders being used in industry, but have never operated one myself. When I eventually get a surface grinder in my home shop, I'll certainly be reviewing this video series!
If you turn the machine off you have to true the wheel again when you turn it back on,no?
Just got a brown and sharp 618 ,580.$ at an auction
I bought one for $1 on auction
Works too
Lol thanks I needed a laugh )) dry grinding ? Your fired
Once you have a side ground, you can tap it down lightly on the mag chuck with a softer metal tapper. You do this after the magnet is on. This is really paranoia speaking, but it makes sure the part is down.
I agree with the two thousandths maximum for manual grinders like that. Any more and it’s super easy to get burn marks.
Seems tile that’ll get exhausting for your arms , no ?
Where have you been Marc I’m resorting to watching old videos !

Why don't you just use vinegar to remove heat scale? It takes some time but it works wonders on raw steel. It seems like it would take a long time to remove the scale. [I'm a noob so I dont' now how thick that scale is, though]
