How to wire motor plug

Is this a brand new purchase or second hand/used.

jinsingh, seriously are you going to use this in a business, or for DIY at home?

As far as protective conductors go, the Chinese have weird ideas, I've spent time out there teaching a company to comply with EU requirements.
Their socket outlets are not necessarily earthed, so they fit a separate point to earth the equipment back to an earth marshalling terminal mounted on the wall.

As it stands.
Either way, this equipment is not legal for use in the EU, nor is it legal to import.
If this is going into a business, I seriously suggest you re-think, as the offence is criminal, not civil.
If it is for DIY, just beware that it has been imported illegally, and would be illegal to sell second hand should you feel so inclined.
It would be likely that it would void any house insurance claims if something went wrong.

Seems a company called AliExpress market these but the UK site doesn't have them so it must has been obtained outside of the EU.

Yes that is correct it is for DIY use only

It would be unwise to give advise on how to connect the machine because if it is not earthed it is not safe. Have you purchased it as a new machine or second hand/used.

Purchased as new from aliexpress.

If that's brand new then I wouldn't be happy with the condition of it.

That is a proper lash up, I would send it back as it's not safe or fit for use.

If they have lashed the electrics up what else have they lashed up, I wouldn't want to be near it when that wheel gets up to speed.

As above it is not safe for use you need to contact the supplier.

It is typical of a cheep Chinese import machine.
I would expect it to cost more to bring up to uk standards than you have paid for it.

it also looks as though it may have no means of earthing, although that would have to be confirmed.

I doubt you will find a reputable electrician that will be able to sort it out and connect it up whilst achieving a suitable level of machine safety unless you are willing to pay a lot of money.

I am seeing amongst other things

lack of guarding
no emergency stop button
all signage is in a foreign script so cant be read.
probable that m/c is not earthed
cables do not appear to be going through correct glands
it is undoubtedly not CE marked.

I think you have 2 choices

1. send it back for a refund
2. find a guy down the pub that knows about electric stuff and buy him a beer. (p.s. this would be against my advice and the majority of the comments above)

Was it actually imported into this country as I couldn't find it on the UK AliExpress site.

I think if it was earthed it's also pretty likely to be unsafe!

You are not wrong there.

I think it is earthed. The blacks of the supply and motor cables disappear out of shot near the switch, I expect to a couple of tags under some convenient screw. The supply cable has the three Chinese phase colours plus a black earth.

But I like Davesparks' comment which sums it all up, it's pretty likely to be unsafe in ways more insidious that having funky colours in the mains cable. OP, sorry, don't mean to be disparaging, but on here we tend to say it as we see it.

Even if you could get this unit to work.

There is a reason surface grinders are not bench tools. The vibration and accuracy need to be compensated for, so usually are quite heavy units.

So I imagine, even if you're willing to spend a large (an it would be large) amount of money to bring it in line with UK safety requirements, the machine probably wont be very good.
