Thread: Diamond grinding wheels
28/02/2018 11:59:32

Use Diamond for Carbide and CBN for HSS.

Also use good quality wheels (we used Norton Abrasives for our standard grinding wheels).

You could also look into having the sub base Pressure Grouted to stabalise and strengthen it.

Hi Bruno,

It's usual to put a Joggle in the steam pipe as per your third option.

There is also an alternative method of sealing the steam pipe at the smoke box end, that eliminates the need for two threads of equal pitch and instead uses an "O" ring seal. Discussed here:- **LINK**

Here's another set of tables, that cover a lot of extra pitches and TPI (goes down to 0.20mm pitch for M1.0 Fine)

Thread: Dro units
13/11/2017 11:38:46

Just tried 127 on my Sino readout and it accepted it with no problem. I used a pcd of 360mm. what pcd did you use, as that may be the limiting factor (if you post the pcd you used I'll try that in my setup)?

The maximum number of holes you can enter in the PCD function of the Newall DP700 readout (fitted on my Myford S7) is 999

Also the Anilam Wizard and Mini-Wizards I've used in the past are DRO's

Thread: Milling machine taper choice ?
22/10/2017 11:26:40

The key in R8 taper spindles is there only to prevent the collet rotating, as the drawbar is tightened or undone.

For the ISO/NT 30 thaper spindle, I have a set of these collets :- **LINK**

that I use on my Syil X5 and manual mill, when I need that little bit extra height capcity.

Thread: Surface grinding without coolant?
13/09/2017 09:56:09

You use a different wheel for dry grinding, usually a "White" Aluminium Oxide, with a softer bond compared to those used with coolant.

After all most manual cutter re-sharpening is done dry.

Check out the Norton Abrasives website for details **LINK**

Thread: Angular contact bearings 7201-2RS

Hi Colin,

This video shows how they work.

 
If you needed to use the puller on an intact bearing, then it would probably require extra clearance machining in it, to clear the outer race.

Hi Colin,

Use this type of puller

Thread: Drill bits

Hi Vic,

the smaller sizes have the HSS Flash Butt Welded to the softer shank and the larger (usually morse tapere shank) are Friction Welded.

It's also possible that some manufacturers may have Induction Hardened part of the HSS blank, to achieve the same result.

Searching for Flash Butt Welding, Butt Flash Welding, Friction Welding and Induction Hardening will bring up plenty of information on the processes for you.

Hi Russell,

It's Propylene.

Nick.

Thanks. So, it's the same as the current formulation of MAPP gas.

Russell

I've just checked the label on my bottle and it's pure Propylene, not a mixed MAPP gas.

Nick.
