Moving Cin Arrow 500 (help blocking head?)

[new2kit]

I need to move a Cincinnati Arrow 500 across town about 20 miles.
Can anyone tell me what is the procedure in locking down the head and counter wieghts on this machine prior to moving?

Thanks in advance for any help!

Well I assume you do not have the bracket that came with the machine when it shipped so you have a few options. If it is only 20 miles put a piece of wood on the table thick enough to bring the spindle face in contact with it lower the z axis to contact the wood with a slight pressure. On the weights you can get away with heavy duty cable ties to prevent then from swinging around. If you can get at the z axis screw wrap a piece of heavy duty rubber around it as close to the nut as you can get it then hose clamp it in place this will help to stop the screw from backing off and moving the spindle face away from the wood block. The other option is to make a new bracket, I would not go to that kind of trouble for a 20 mile trip however as long as you take it easy on the roads you will be fine.

Do not support directly under the spindle by means of placing the block of wood directly on the spindle nose, doing so you are putting pressure right on the bearings. Build up the wood right behind the spindle were there is the solid steel headstock you can then tie the head down to the table with straps to prevent head bounce on the road. If you load on the spindle and have a major head bounce while in travel you could ruin the bearings.

Slick27 is right should have clarified that it depends on the design of the machine. The spindle on my machining centers has a round housing around it the spindle itself rotates in that housing and that is where the blocking should go. You are talking 20 miles and also a truck with rubber tires and a suspension so unless he drives into a 2 foot hole you do not have to worry too much about it.You will never generate a shock hard enough to cause bearing damage. You will see a much harder hit on those bearings if you had a crash caused my a z axis error, they are designed to take an axial and radial load. In fact a drill peck cycle could cause more of a shock load than you are ever likely to see on the bed of a truck. Keep in mind that the head is still connected to the lead screw this prevents direct transmission of the load into the spindle bearings, it will transfer nearly all that load into the screw since it is preventing further downward movement itself.
I moved machines short distances without any blocking at all with no damage resulting but for the few minutes it will take to block it why not do it so you do not have to worry.

This is jeff factory trained where there build birmingham ,england. Do not block on spindle bearings. Block behind spindle. I service cincinnati
in california if any needs help call 209-532-1797

Always block the counterbalance ! There should be a hole through the column, and a matching hole in the counterweight, or at least rest the counterweight on a bar placed through the hole. Blocking on the spindle nose is just asking for trouble, you may get away with it once or twice, but its just hammering on a non rotating bearing. Same thing with a counterbalance, it's going to jump up and down without being blocked, and try to pull the head off the table block. Move the spindle down close to the table, at that point you should see a way to bar the counterbalance. Once done, lift the head slightly, allowing a small amount of slack in the chain, and block the head. Remember, the day you move will be the first rain storm in months. Have tarps handy.

No counterbalance on these machines.

You may want to tie the table in position too.

What, you mean there is no counter wieght on this machine type?
I do not need to worry about the counter wieght because there is none?
