Hi everyone :wave:

I am loooking at the possibility of upgrading my old cincinatti knee mill to a

Haas TM-1 but does anyone have a birds eye plan of the machine working

envelope especially showing how the electrical cabinet opens at the rear of

the machine .

Also does anyone have any opinion on how suitible this machine is for general

subcon toolmaking (including copper electrodes for edm-ing )(Is 1meg enough memory )( accuracy )??

The Haas web site has dimensions that you are looking for. Click on the dimensions block after you open the screen to view the details on the TM-1.

Buy as much memory as you can. The Ethernet option would also be a good buy

Thanks WOLOG for your reply but the haas website only has a front view of

the machine and says the depth is 64" but needs 35" for cabinet and i am

trying to fit the machine in to a very tight space which is why i need to find

the shape/size of the back and how it opens for maintenance.

Haas cheated with the dimensions. They put dimensions for all of the other machines. The control cabinet is the same on every machine. It is 36" wide x 48" high. I would say that once you get the machine installed and running, pick the machine up with a pallet jack and move it where you want it. You should not have to open the cabinet for a while. I have a VF-5 50 taper and I have not opened the cabinet in a year or so. If you need more info, I can talk to one of the guys at my HFO and get what you need.

Hi kevh:

On our standard HAAS machines VF0, -2, -3 which have 36" wide cabinets
we space the back of the door when closed 39" from the wall. The heat
exchange area protrudes somewhat back of the door but this is no problem.
This provides 1" to 2" of clearance when the door is at 90 degrees.

You certainly want to be able to swing the door 90 degrees open.

On memory: At least 1 megabyte for general use. If you have large
programs, meaning many megabytes, then can you afford enough memory
to allow fully loading your largest or typically largest program(s)? If not then
1 meg maybe a good choice.

If you can not fit an entire program in memory, then it must be broken into
parts or use drip feed. I personally do like like a mechanical disk for memory
on any machine tool. It is ideal to have the entire CNC program stored in
CNC RAM memory. This avoids problems from errors during machining from
data transfer. If the entire program is in CNC memory, then after it is loaded
you can send it back to the source, do a file comparison and have knowledge
that the data in the CNC memory is exactly what was sent from the central
computer.

In drip mode HAAS uses available memory as a drip mode buffer. So if you
do not keep much of your memory full, then you have a large buffer that
can average variations in machine useage with respect to drip feed data
input. I have heard that Fanuc only buffers 10 bytes or thereabouts.

If the RS232 input is set for 7 data bits, Even parity, and 1 stop bit,
then I can transfer about 600,000 bytes per minute at 115.2 kbaud.
We can transfer RS232 data at 115.2 kbaud over long distances (4000 ft)
with very low error rates.

The HAAS machines are very easy to work with, and are quick and easy for
data transfer.

In general I would prefer a fully enclosed machine with a side mount turret.
If you are doing contouring you may want a high speed spindle.

Compare HAAS to other machines for operator panel convience and you will
want a HAAS for job shop applications.

Thanks Gar for your help.

I have now spoken to a rep and the rs232 drip feeding conection seems the sensible solution for my budget if I feel the the need to ever carry out 3D ops

Also it sounds very easy to move the machine with a set of pallet trucks to access the rear cabinet.

Anybody compared the haas control with the "XYZ Protrak Control " for simple programming ?? (in PC terms the protrak is a much higher performance control but is this necessary??)

(Ps any suggestions for tooling??)
