Thanks. Heaps of good advice there. Coolant concentration was something I was worrying about. I usually run about 5% which is manufacturers recommendation. Not sure I am brave enough to put my...
You are probably right. Knowing my luck I will probably break a carbide drill in the bottom of a hole and it will be stuck in there forever as a reminder! To be honest I don't know why I ordered...
I have ordered some carbide tools, so will get into this project in a few weeks. Will see how the mid range Chinese tooling holds out! I have read that pecking should be avoided with carbide and...
Thanks, I have used the Sutton catalog before, they are pretty clear and simple. If only I could buy Sutton tools here, they are made just down the road!
I am building myself a fixture plate, picture attached. Made from a chunk of 25mm thick G350 steel I found lying around, approx 300 x 400mm. I don't often work with steel and if I do its small...
Small world, I am Bank Peninsula, work in Christchurch!!! I will check out Harvey Tools. I also need to get some lathe tooling so that could make the freight worth it.
OK, thanks Craig for the suggestion. where in NZ are you from?
I haven't used one of those freight forwarding services before. I usually buy from the UK/Europe as freight is usually a fraction...
OK, thanks for that. In some respects I am stuck with what I can buy in New Zealand. Freight from anywhere but China is prohibitive. In fact nearly all suppliers here stock only unbranded Chinese...
My feeling so far is that the best solution for me is to use two tools, one for chamfering and another for spot drilling/countersinking.
A four flute carbide drill mill or chamfer tool for fast...
I hear you. It was more a point of interest. I want only a 90 deg tool so it can be multi use.
Cool, thanks for the advice. I hadn't seen your website, I will check it out...
Yup, definitely keen to know. My machine is very small. It is a Mazak, but has similar cutting capacity to a Tormach 1100. I had assumed indexable tools for things like spotting would be large. ...
Another question on this. If I was to use a 90 deg spot drill / chamfer tool.... Is a 90 deg spot drill a good idea?
I know that generally for carbide drills, you should use a spot drill of...
Thanks everyone for your replies. It has confirmed what I thought that those tools are not suitable for plunging. Oh well, guess I will need to use two tool slots. Does anybody have any...
I have been using the tool at the link below for chamfering. I thought when I purchased it that it would also be good for center drilling. I only have 10 tool slots in my CNC so combining center...
After looking at the manual, these are pretty interesting. It has all the wiring connections I want except analog output and supports the encoder I have. Unfortunately the manual does not have an...
Swapping out the motor is a little tricky mechanically. I also have a perfectly working motor already mounted and wired so a waste to replace it. I have options for drives but they are much more...
Haha, I am also an electronics engineer. I did contemplate making one. I also have the original Mazak power amplifier that I could use as a base by throwing a micro or FPGA onto it. But the...
I am some months into a retrofit of a Mazak machining center with Centroid controller and have become stuck on driving the AC servo spindle motor.
General googling suggested using a VFD for the...
Haha, yeah I have seen one of those old hardware based controllers. This controller is not that bad. It runs on an Intel 486 CPU. It can do some of the more complex operations like helix milling,...
See that is where the disagreement is. Everybody else and all my testing says that any standard controller should be able to perform this operation.
My controller does support R but it does the...
For future reference... I purchased a manual for the machine. Here is what the buttons do:
- The key shared with F/E is screen on/off. Press it in combination with MF1 to turn the screen on and...
So... the manual turned up for my machine. Quite a comprehensive manual about everything except g code programming. A huge section on what all the buttons do and a huge section on macro...
I woulld be keen to hear more about this problem and any code examples that you may have where it went wrong!
Yep, keen to get that manual. I had another surprise tonight where I found out that a G53 uses tool length offset! All the other manuals I have read say that a G53 will cancel tool length offset. ...
OK, you are the first person to mention this! Can you please elaborate? My test program is in the attached pdf for reference.
OK, so it seems there is some confusion over tool length compensation and tool offset and wear adjustment. I didn't know there was a difference between 'tool length compensation' and 'tool offset'! ...
I haven't wasted any time trying to get cutter diameter compensation working on G18 plane. I know it is applied on the X axis. I have tested it for interest and it seems to work as expected.
But...
I would like to think I understand basic programming well enough, particularly on the XY plane and typical tool pathing. I am certainly not a master but not completely ignorant. However I want to...
Sorry, I don't mean to sound rude, but I think you are not getting it. The entire point of this post is that my machine cant do a G18 arc when tool length compensation is turned on. Instead it...
