Onsrud has had quite a few complaints lately the shear of the cutter goes far up the shank. Is there any shear inside your collet? This allows them to use a bigger wheel when grinding, but the use too much shank causing breakage at the collet rgds George

Kaeser screw type, is an excellent unit. I have personally worked with well over 100 of these, in router applications rgds George

Tommy I always use the filter. But when I cut high speeds, grater than 900 ipm, I draw the ellipse in autocad. In autocad at the command prompt type pellipse set this variable to 1, then draw the ellipse. It will be 12 arcs. And will cut the way you want rgds George

Ok I'll tell you Fanuc means Fujitsu Automated Numerical Control

I spent 2 weeks in Fanuc's school in Japan a few years back. It is Fan Uck I actually learned what Fanuc stands for Does anyone want to take a guess? rgds George

Jeff I seem to remember something about this, please go to your parameter manual and go to parameters related to tool offset this is a parameter that discusses tool length offset values. Lee I dont know if you have the small or full size keypad. From the relative position screen press the X or Y or Z then press CAN theis will clear the relative value. As far as the part counter press P then CAN for run time press R then CAN. rgds George

If the cycle start light stays on STL is commanded and the nc has not issued a FIN or finish signal. When an M code is executed something has to happen. Execute all the m codes through that program one at a time in MDI and see which one fails. Perhaps it is a simple sensor or limit switch adjustment. Do you have a copy of the ladder logic? This will help you find what has to answer back the specific m code that is failing good luck George

You need tool offset c so you can use one offset for both D and H ie G41D1Y1. G43H1z1. this is an option from fanuc rgds George

Eastech is this a shoda machine? I have programmed hundreds of these machines,I always rotate the part 90 degrees rgds George

Aaronis You could purchase the user macro b option for your fanuc control and program parametrically. rgds George

Most of the older Heians came with a tape reader, be sure the i/o settings are set to remote. Parameters 340 341 and 311 are for rs232 if memory serves me correctly. If you need any help with the Heian please ask me I was Heian's engineer in America from 1983 to 1989 rgds George Gerhard

If this is a Fanuc control with the pc interface you must omit the percent sign. When I say pc interface I mean there is a conventional crt and pc board. I learned this the hardway rgds George

dkintzel I have done alot of work including the original training about 18 years ago at Northway Industries. I recently modified one of their Heians with a new plc. I actually tried to sell one of my machines to your company many years ago small world gota loves this forum regards George

Ripper if you take the 45 degree tool and run it into the corner there will be a huge radius in the corners. However if at the corners you execute a 3d move equal to the tool geometry there will be what appears to be a square corner, there will always be some radius, but it will be very small. rgds George

Ripper In order to cut a square corner, whrn the machine arrives at the corner the corner the machine must move x,y and z simultaneously. Engraving will figure out the moves for you ie, G01 X1.2345 Y1.2345 Z1.6875 rgds George
