Lathe charging.

[Hood]

It's all the cost of set up, on a cnc, if local firms need one bit, then the local chap with a conventional lathe is at a premium it would seem.

That's round here.

Lathe work, machining hourly rate, plus whatever costs are involved to tooling.

It all depends, really a CNC with tools already defined and offsets save or with a toolsetter for quick tool setup then one offs are usually quicker than on a manual. Having said that I do more on my manual lathe than the CNC

Here, my colleagues find for one off simple pieces, it's exorbitant at cnc places , and it's a half hour each way.

 

[Barking Mat]

Because conventional lathes are becoming redundant over here apparently.

In machine workshops, companies need turnover, and quantity, my point.

As my old governor used to say "like a prick in a bowler hat" to this day i don't know where it comes from but it fits a multitude situations.

We say, "Like a hot dog up a hallway"

Aye, most likely because they want large numbers rather than one off jobs so they charge a premium to try and put you off.

Only you can say, since you're the only one that's done the job On the face of it, if its only boring out 48 to 53mm on an existing sleeve at length, then I can't see how it would take longer than 1 hour each. But I'm maybe not seeing something here.

I could only take 0.25mm per time or it broke a tip if it did not break it the interupt was visibly moving the top slide.

This was the reason for asking to see how others saw it. I knew CNC would not compete on price as there was only 2. Setup would easily make it not viable.
They were told it would not be done for 3 weeks at their local machine shop.
This is why I have never set up in business. It just seems impossible to me to price anything fairly.

I thought the same as Barking Matt so how wrong was I lol...

What size bar and type of inserts were you using?

Not really not I re read your reply. Yes I did the job and I had no reason to drag it out but I really struggled with the first one. Second one was a bit easier to cut but the interupt was not happy with a bigger cut.

A pro would know what tool to use. What speeds. What insert. Depth of cut etc etc etc.

I suppose my question should be...if I wanted the work done by one of you guys what would you charge.... I am assuming you would be expected to give a quote in advance or is that not done?

As I have the VDI turret I made on the lathe it means I can have loads of tools already set up and just have to fit the tool into the turret, write some quick code either via MDI on the machine or as I can type quicker on the PC I usually write a programme and pass it to the CNC via the wifi network.
So basically for something simple like this I would use a G90 canned cycle, code would look something like this

G54 G99
T2323
M44 M3 S1000
G0X47 Z5 M8
G1 Z2 F0.2
G90X49 Z-150
X50
X51
X52
X53
G0 X100 Z100
M5 M9
M30

I don't get the idea that manual is quicker i can't see its quicker than a smooth operator

Ok so what would your quote be...lol

2 to 3 hours at shop rates allowing for hard material and interrupted cut? I dunno. Again, you know what the situation and job was like better than we do.
If he wants to pay less than you can realistically afford to charge, then let someone else flog their lathe and themselves to death.

To make the job go easier if its not a one off, maybe find some inserts rated for interrupted cuts... Might help... I dunno what your setups like

 

[mtt.tr]

I wouldn't quote it as until its in the machine you can't know what it will take.


I would give an estimate on time and an hourly rate which varies from:
*Minimum i need to earn per hour
Through to
*Dont really want the jobs seems like agro so my price is a hope the customer will say no.

There wouldn't be one
I very rarely get asked to price things, they pay me for the time it takes and consumables used

You're in a bit of a niche and captive market with your skills, though although it's maybe just how it looks from here

It is the way I like it

 

[mike os]

At that rate its going to be about £200 each..?...

Bigger boring bar with more robust tips might help but interrupted cuts in hard material is always hard on tips.

What happens with the keyway? Recut?

I used a 40mm bar.
