You can install a momentary push button switch to bypass the limits so that you can jog off a switch after hitting it. It is a good idea to have the limits designed so that the machine can travel a...
Hi kolokithas,
Here is the real TLO scoop. When you set up a CNC Mill, you must have a z home position to reliably use TLO. This requires a home switch on the top of the Z axis travel and...
With a 5 tpi ball screw, I would use a minimum 3:1 reduction and possibly even 4:1. If your motor can do 2000 rpm 3:1 gives 133 ipm, plenty fast. The theoretical stall load should be around 480 lbs...
It is over a grand when you have to equip 4 machines
Thanks Steve,
I did some research at the web site today and was taken back by the $$$$ price.
With my ongoing health concerns with coolant mist in the shop air, I have been planning to build a...
Hello SJH,
Beautiful conversion job, my complimemts. I am interested in this fog buster coolant system and have never saw it for sale. Where can it be purchased. I am sick of breathing all the...
That is a great buy. Clausings are excellent machines and you have struck gold on this one.
I also struck pay dirt with mine. I paid $400 and it came with 6 Albreich chucks ($1080) and about $...
Hi Larry,
Another thought on your mill project in addition to concrete filler. When you look at most mill drills such as the RF-45, you notice that the head assembly mounts to the column in such a...
I think your approach has definit merit. I have a post somewhere here suggesting exactly the same project as yours. MY idea was to use 4 x 6 or 6 x 8 steel sections and fill them with plasticised...
Adobe,
I can't say enough about how important precision homing switches are. Many times I feel that it falls on deaf ears with the benchtop hobby guys. An investment in a few high precision...
It would be really cool if the DeskCNC software/Hardware had an encoder counting feature that could display a virtual dro popup independent of the cnc software functions. This would provide a...
A friend of mine worked for a company that owned munuitions plants and told me about a lathe with a 150 ft. center to center distance. I think he may have also said something about another with a...
Hi Adobe,
I have posted a table of roll tap drill sizes under the General Metal Working Machines heading as a PDF attachment.
Dennis
I have attached a table of drill sizes for thread forming taps and a formula for calculating minimum and maximum drill sizes.
A combination draw bar wrench and brass striking hammer is available from many machine tooling suppliers. Th air wrenches are very fast when properly hanging nearby for quick access.
I do all tapping with Tapmatic tapping heads including those done on my cnc machines. I have one mill that has instantaneous reverse capability and do tap with a rigid configuration at low rpm on it...
This has probably been considered but here goes.. Make sure that the spindle taper is absolutly clean and free of any shipping cosmoline, use a bit of solvent.. After cleaning the taper and collet...
I try to keep the faith and have purchased 5 new ford and lincoln products over the last 10 yrs... I think part of the problem is as you stated being the greedy managment resting on their laurels and...
Woh,,,
Can't throw a $ 1500 programmable dro in the trash.. Is it possible to read the quadrature output of the glass scales with both devices ???? The scale system is running on 5VDC regardless...
Hi Adobe,
Things are looking really great with your project.. THere is no substitute for old American Iron when it comes to manual machines... Where did it all go wrong,,, we taught the world and...
Burn,
I dont have any experience with these boards. At one time, I was looking at the CNC4PC board. Check out the web site at .com
So it seems that there is some possibility here.. I have a RF 45 equipped with an Anilam wizard 800 dro. I am currently installing ground ball screws that I obtained a while back on the x - y, and...
Does anyone have experience using linear glass scale as servo encoders on vertical milling machines.... I recall reading that dro scales such as Anilams will cause servo fault problems due to machine...
Hi Adobe,
With most pc servo systems, the servos boards are linked together with a fault circuit. I specifically use the IMServe boards so this info is based on them. When an axis count error...
Mounting a cutter from the side may work, but it is close,,, the boring head will be about 50 + mm in dia with no offset and the cutter must extend below the bottom surface of the head to reach the...
I don't think that a boring head will work well in a spiral cutting mode and an end mill offers superior stiffness... Also,,I think that a lot depends on the rigidness of the machine itself....The...
What you possibly may consider is using a 3/8" dia solid carbide boring bar in a smaller boring head. Carbide bars are 5X stiffer than steel ones so the finish is typically far superior. The rule of...
Burn,,
If you buy the complete system from IMService, You get the controller board, servo driver boards and motors. I don't think you need a breakout board because the controller in this kit is...
Thanks for the compliment.
I have a small woodworking tool mfg business and use this lathe to make a special brass threaded stud, dowel pins and shaft collars. It is pretty much capable of making...
