I am looking for a HSS square end mill, 1 in. dia with 12" length of cut (minimum); number of flutes is not critical. I need it very quickly so if there is something off the shelf that would be ideal. Any suggestions?

It might be really simple but I cannot find a way of drawing an arrow (no text, no leader) in NX5. Is there an option that I am not looking at?? Thanks.

I am working on NX5.0.0.25 with .dwg files from Autocad. The views are not to scale and I need to add dimensions. I am having some trouble 'inputting' the dimensions on the drawing. What is the best way to get the dimensions onto the drawing in this case? Thanks.

Hi, I am looking for 0.5" radius isert to fit in a 3" shell mill in an HSK 63A toolholder of 4" length to machine plastic material. I did find this with Kennametal, but uses an extension for the toolholder thus making it heavy. Is there another company that can satisfy the requirements? The...

Hi, We are interested in purchasing a 5 axis machine from a manufacturer in Europe. For that purpose, few trials are to be done in order to ascertain suitability of the machine for our application. I would like any ideas on what are the critical areas that need to be looked at for example...

Hi, We are looking for a cnc router for machining and also polishing plastic (specifically acrylic). We have one at present (110"X110" table) but it does not have polishing capability. Please suggest routers out there that can accomplish both. Also the present router has a limitation on...

Hello, We are thinking about purchasing a new CNC machine for which a machine specification document is to be prepared. I have never done one before. Is there a sample or a resource I can refer to as a guide which will help me prepare one. Thanks!

We are researching 5 axis CNC machines for purchase. At present we use Haas VR11 machines, however the requirement is for a machine having minimum of 60" travel in the Y axis (VR11 has 40"). Most of the machines similar to the VR11's have less than that. Does anyone have input on a machine...

I am using NX4 and would like to know how to find the area contained within a profile created in UG. The profile is a set of splines. Thanks.

I have experience with 3 axis CNC programming and would like to expand the knowledge to 5 axis programming. I have access to Catia V5 and UG NX4 manufacturing modules. Are there any sources available for tutorials that could be useful (or even books to help in learning)? Thanks.

I am looking for an insert with 0.5" corner radius for face milling polycarbonate. I have spoken to a few insert manufacturers and none of them have inserts with this corner radius. Does anyone have any insights on where I could find these? Thanks for your help.

I would like to know if anyone has worked with a KUMA coolant unit. We have one on a 5axis CNC machine, and have been getting alarms about level of coolant. Please let me know. Thanks.

We will be machining profiles from a 10'x10' acrylic sheet (0.1" to 0.9" thickness) on a cnc router. The router (one which is being researched for purchase) has a 10hp dry vane pump ((175cfm @ 28in Hg) and pulls vacuum through MDF. I have not seen the machine run and would like to know if...

Hi, We are attempting to flycut an acrylic billet on a 3axis CNC high speed router (max rpm = 18000, max feed = 800ipm). So far we have used PCD inserts at different feed rates. The issue is the tool marks and also ridges at tool stepover. The feed rates were dropped to 50ipm and the tool...

Hi, I am attempting to machining a laminate of acrylic/polycarb with an interlayer of urethane. I have machined polycarb and acrylic before but never with the interlayer. Since I have been told that machining urethane is totally different from the other plastics, I would like to know if...

Hi, We recently purchased a high speed router for machining plastic (acrylic, nylon, fiberglass). The parts are covered with paper for protection from scratches and has to be present when machining. The issue is that while machining with a conventional upcut endmill, the paper is not cut...

Hi, I am having difficulty with part fixturing on a vacuum table purchased recently. The application is high speed CNC routing of plactic (acrylic, polycarb, composites). Parts are normally covered with protective paper which further weakens vacuum suction. If anyone has...

The coolant in our machine shop produces an odor when stagnant for a period of time. Is there a way this can be prevented? The coolant used is Boelube 70105-05. Any helpful comments will be appreciated. Thanks.

Hi, I urgently require RDO-35 collets [EXNG32-0-.25 (.250 ID), EXNG32-0-.50(.500 ID)] for a European machine and have not been able to find an American manufacturer/distributor for them. If anyone has information regarding where I can obtain these collets from please let me know asap. I would...
