A simple solution to a problem I was not aware of - two lessons in one. Much appreciated. What do you think of the idea of 3D printing a dummy block (with metal or magnetic inserts)?

I love the idea of 3-D Printing, as you probably know from watching other videos on the channel Especially using it if there was a problem with thermal expansion in a certain spot on the part, you could direct them majority of flow to that area. Interesting. I love hearing other peoples ideas and points of view. Thank you so much for contributing. Ray

Why not point the coolant stream at the wheel. Then it would always be wet?

Most nozzles or nondirectional You can only adjust the up-and-down some have flexible tips, which make it a little bit bit easier to do that Keep in mind, you want high, low pressure if you have high-pressure, hitting the wheel and the wheel, larger, or thicker than you might run into a situation where the wheel could hydroplane By putting a block in front coolant to flow easily over the workpiece before the grinding wheel engages in cutting there are a few things you can do to make the situation, not as bad by reducing your cut depth, and also making certain that you have a large diameter wheel, which increases your cutting speed The simplicity of just adding a few blocks to allow the coolant to flow is the best resolution to a simple problem

Add coolant stream to both sides of the wheel.

It’s very difficult to add coolant to the opposite side of the wheel because the centre fugal force of the wheel will actually blow the coolant away If you had Center, fugal coolant, where you put coolant into the centre of the wheel, that is the best way of providing lubrication to the cutting surface The drawback to this is that it doesn’t only provide coolant to where you need it. It provides it to the whole circumference of the wheel at the same time. Therefore, that type of coolant system is best in an enclosed grinder. Thank you for contributing everyone’s comments are appreciated and helps promote different points of view and different experiences

Sorry, what am I missing? Why not just aim the coolant directly on the wheel?

if you have the ability to do so, that would be the best, but unfortunately, you can tell the machines are not quite designed that way because of the different size wheels you can put on some machines have adaptive nozzles that allow for that, but not all due You don’t want to use a super high pressure because coolant will go everywhere, and if you have high volume high-pressure, the wheel could hydroplane All of my videos are designed for students or people learning, so if they understand the concept of having coolant in the area that is required at the time that it is required Take a few minutes and look around your shop and see how many people are dry grinding when they think that they’re actually wet grinding and you would be surprised Thank you for taking the time to comment helps other people as well Ray

I don’t quite understand what you’re asking

Can’t you just increase your coolant flow?

@shopandmath

3 ай бұрын

if you have a machine like ours, you can’t redirect the coolant flow or increase it enough. If you have a block that’s sticking up 2 inches you would have to have a coolant flow like you’ve never seen and if you could do that pressure would be too high. It would be such a mess everywhere because these units are not enclosed You want high, low pressure because you don’t want the wheel to hydroplane

@@shopandmath could your 3-D print a new nozzle so the cooling gets a little bit closer period. That way you won’t have to make blocks for each and every job.

this is the second excellent idea that’s come across to help solve this problem today I’ll have to put that in the idea bank as a good way of readjusting the coolant flow The main idea of this obviously is for students to understand that, by placing a block there to allow the coolant float to slide over, top it prevent dry grinding, and possibly prevent warping, depending on the material and the set up Thank you for sharing your idea. It is much appreciated.

The coolant supply should be almost horizontal to the bed with the end almost touching the wheel. If the supply was adjusted this way it would work for all workpiece thicknesses.
