| How thick is the coating? |
1-4 microns thick (25 microns = 0.001 inch) |
| What is the build-up? |
Uniform 1-4 microns over the entire surface being coated. |
| Can I re-coat? |
Yes, but increased film stress due to coating thickness may cause failures. |
| What does PVD mean? |
Physical Vapor Deposition. |
| What is the difference between PVD and CVD (Chemical Vapor Deposition)? |
CVD coatings are usually thicker and are done at higher temperatures. |
| How much does the coating penetrate into the surface? |
Not at all. |
| Can you strip the coating? |
Yes, on steels. |
| Can you “mask”certain areas of the tool? |
Yes, the shank of a cutting tool is automatically masked. Masking on other types of parts can be done for additional cost. |
| Can you coat over black oxide? |
No. |
| Can you coat over chrome plating? |
Yes. |
| I already have tools coated with TiN; but now I want TiAlN. Can you simply coat over the TiN? |
Yes, but there may be issues with the total coating thickness and performance will not equal coating on uncoated tools. |
| How do you price the coating? |
Coating type, quantity, part size, and load size. |
| Can you “double dip” the tool for me? |
No, coatings are optimized for the correct thickness. Too thick and the coating will fail. |
| What about coating inside diameters? |
We can coat 1-1/2 times the diameter of the bore down into the part. |
| What can you coat? |
Carbides, Steels (some considerations due to temperature), light alloys (engineering approval), non-ferrous heavy metals (engineering approval), electroplated parts (engineering approval) |
| Can you coat aluminum? |
Yes, but requires engineering approval. |
| I have a tool that I only need the tip coated so can I get a better price? |
No, coating price is based on the total volume that the tool takes up. |
| What is the smallest tool you can coat? |
Tools as small as you can make. Tools as small as 0.015″ are common. Smaller tools may require special tooling. |
| What is your turn around time? |
Typically 3-5 days for PVD. |
| Can you do 24 hr. or 48 hr. service? How much? |
Yes, with expedite charges. |
| Do I have to do anything special to the tools before I send them in? |
No. |
| Do you have quantity breaks for better pricing? |
Consult with our Sales Staff. |
| What about “brazed tip” tooling? |
We need to know the braze temperature. |
| How long does the actual coating process take? |
6 to 8 hours. |
| Can I clean the tools/parts myself and save time and money? |
No, the cleaning is an important part of the coating process. |
| Do I need special coolants for coated tools? |
No. |
| Can I run “dry” with coatings? |
Speak with our Application Engineers. |
| Do you have a minimum order charge? |
$100.00 |
