Learn how to properly apply authentic Turcite and Turcite Rod products for maximum benefit — Machine Tool Specialty Components Group.

Hello everyone, Most know I am a Machine Rebuilder and teach rebuilding / scraping seminars. I have a reader who emailed me and wants to know about scraping a machine that now has Turcite on it. I asked him to ask his question on the forum so all can see. I had another thread but it got off topic and I want to start a new one again.

Hopefully he will ask his question today or tonight. Any of you others who have questions please ask as this board has several qualified machine repairmen and Rebuilders who can who can help answer questions. Richard King.

Installation Instructions for Turcite-B 1. Turcite Bonding Surface: Turcite-B Linear Bearing Materials are thin, flat, fluoropolymer-based sheets, which are secured To metal substrates through epoxy adhesive bonding. Turcite B is chemically etched to accept Trelleborg’s Waylock epoxy bonding adhesive. What is Turcite ® (Lubring)? Turcite ® is PTFE impregnated with fillers and additives that serve to enhance the wear properties of the material.

Here is the question Richard reffered to: I am rebuilding an FP3NC tool room milling machine. As a point of reference this machine is in my home shop. Main vertical casting of the machine which carries the 'Z' axis has box ways. Sliding on the box ways is a vertical slide (sort of kike a conventional BP knee) It carries the ways for the table ('X' axis). The 'X' axis is a 'T' slotted table,but mounted vertically, that is to say the face of the table is parallel with the 'Z' axis.

Here is the general arrangement, with the machine shown running using the horizontal spindle. OK now for the problem/question: I am working on the vertical slide ways where the 'table' ('X') fits up. This photo shows the vertical slide sitting on the main machine vertical casting box ways. The base has been removed and the casting laid down for fitting. The area in question is the Turcite surface laying horizontal in the photo.

Its the surface with the circular oil feed grooving in its face. When the machine is assembled, this Turcite will be vertical. Its role is to support the bottom face of the 'X' table from twisting in toward the machine. It counteracts the weight of the table and work and provides a way for the 'X' axis to move against. Also seen is the tapered dovetail above the Turcite that provides the gib adjustment.

Another angle of the Turcite. Here you can also see the scraped iron way at 90* to the Turcite.This way supports the bottom surface of the 'X' slide and takes the weight of the table and work, and is directly opposite the tapered dovetail gib. Here is the problem. There is an area at the lower edge of one of the oil holding grooves where the Turcite has come off. In the assembled machine this gap will be facing down and will cause the oil in the groove to be able to leak out.my fear is that this will rob the slide of proper lube. Additional info: The 'X' axis ways and their mating surfaces on the vertical slide have already been re scraped. Done by a local machine rebuilder who i have used before and who's work is of good quality.

The piece of Turcite came out after i got the parts back form the scraper.so this is not an oversight on his part. Point is that the remaining Turcite surface blues in fine with the 'X' axis ways. Question is should i attempt to jsut spot repair the missing area with additional Turcite (or something else?) Or should i bite the bullet and replace the entire Turcite piece and rescrape. Or, would it be feasible to remove almost all the original Turcite leaving several small islands at each end, and fill with Moglice using the original Turcite as a jig? I am interested in any ideas or suggestions here. Dear Ross, If I was your Rebuilder I would have recommend you replace the Turcite when I saw it.

You should depth Mic and see how thick that Turcite is now. It look to be almost worn out. Psychology Test In Hindi Pdf here.

To be honest I have no clue how thick it was from the Deckel factory, but the majority of new machine builders use.047' and then scrape it so you generally have about.040' when it's finished. From what I see, it looks like.010' to.015' if your lucky. It might be possible it was.030' when new may have been ground or scraped to.025'. In all my years I have only seen.010 used on Hardinge beds and.020 on Okuma Howa VMC's. I usually use.047' or.062'. If you can find a spot where there is little wear or unworn areas see if you can estimate how think it was when new.
