Manual Machining like CNC

Can We Manual Machine like CNC - Machining Can a better finish be achieved using manual machines and CNC like techniques? Here we make a simple stop screw for the Colchester Chipmaster's turret bed stop. We are making four lenghts of this scew with the only difference between them is the lenght of the square head. Ideally the end face of the head wants to be as smooth as possible because this i...

Measuring with digital caliper(vernier) a machined part can sometimes give inacurate readings. Still accurate if tolerance allows.

Internal screwcutting the easy way In this short video we are seeing the usefulness of the bed stop cross slide stop, and compound angle feed for the correct screw thread pitch diameter, the precision way of screwcutting.
Can we modify a Crawford chuck to take 5C Hardinge collets?
Переглядів 3732 роки тому
Modifying a Crawford Truegrip collet chuck to take Hardinge fine thread 20TPI collets The point of this modification is to use the Hardinge 5C collets that are more popular and still available on a Crawford Truegrip collet chuck that has the same features but a different coarse thread. The Hardinge 5C collets have 20TPI right hand thread and the Crawford has a 12TPI left hand thread. For obviou...
Do you still make these thread inserts?
Yes, just acquired material for 50 or so parts. Contact me on fejlong@yahoo.com if you need one
Thank You.
I love it! Thanx for sharing. Also a Joe Pie fan.
If you begin to wonder why you are losing your cutting edge prematurely on that first insert it is more than likely coming from dragging it across the workpiece without the workpiece moving (very first operation). Carbide is very hard but also very brittle because of the hardness. In the case of the lathe the workpiece needs to be revolving every time the carbide contacts it or micro chipping and cracking of the insert are the result.
Hey thanks! Yes, micro cracking is a big thing with carbide and HSS as well. Using coolant intermittently also induces micro cracking in cutting tools. Is that after facing off or rough turning the thread O/D? Edges where not touching in either occasion, video does not show or mention this. Thanks for your comment!
@@chipmaster7738 it is the operation where you set the bar to length from the collet against the side of the tool. You come back to your start point and drag the tip/insert across the non revolving square bar. The insert has to be touching because it is leading.
I agree, it looks like it's dragging across the face
great job, keep it up and soon you will have thousands of subscribers. why do you use oil instead of coolant?
Hi! Thanks for the encouragement! It is industrial cutting oil, doesn't go funny if left unused for a period of time, machine won't rust on the contrary it protects and lubricates the ways.
Love the demonstration. What cutting oil do you use ?
It's STAR 22 ULTRA from Trentlubricants. Quote "Star 22 Ultra is a pale, low odour, chlorine free neat cutting oil containing extreme pressure, anti-wear and lubricity additives blended in carefully selected mineral base oils. APPLICATION Star 22 Ultra is a multi-metal high performance heavy duty neat cutting oil, with medium viscosity characteristics, for use on titanium, high tensile steels, stainless steel and alloys. Specifically designed for use on sliding head CNC and multi-spindle machines and is also suitable for broaching and gear manufacturing."
Excellent step by step video. I really appreciate the captions for each step as opposed to the usual voiceover narration that others do.
Hey thanks Andy! Much appreciated!
