For machining brass, aluminum, copper, polymers and crystalline materials such as calcium fluoride, ZnSe, germanium, silicon and Zinc Sulfide. Radius size from 2-3 microns up to 300mm are available. Waviness can be controlled to <0.05 microns on 0.25mm radius and smaller. Sharp tools for fresnel diffractives and other custom geometries are available. Natural diamond, synthetic diamond, and single crystal CVD diamond are offered, as well as CBN and PCD (Polycrystalline diamond). We braze diamond to any carbide forming metal shank or insert including special dense tungsten for chatter-free cutting.
Technodiamant manufactures a wide range of diamond tools for diamond machining, diamond fly-cutting, and diamond turning. These tools are most often used on Precitech and Moore Nanotechnology Systems high precision turning centers. Edge radius can be either conical or cylindrical, and can be controlled to very tight tolerances, depending on radius size. Radius size can be specified from 15 microns to several hundred millimeters. Clearance angles can be specified from 7 to 30 degrees. We are routinely able to achieve waviness on 0.5 mm radius tool of <0.06 microns over 70 degrees, and <0.06 microns over 100 degrees on 0.25mm radius. Natural diamond is recommended for controlled waviness tools. Please call with details of your requirements for technical information and pricing! We stock several sizes for immediate delivery.
Instead of following other manufacturers in their production method, Technodiamant developed an entirely new process for polishing the radius of diamond tools.
The newly developed machines are equipped with a highly sophisticated bearing system, which enables Technodiamant to polish cutting edges in the “difficult” directions of the diamond. This improves the lifetime of the tool significantly in many applications. At the same time, Technodiamant has improved the lapping and relapping facilities by using a fully automated system. This ensures, in combination with the conical clearance angle, an absolute circle instead of an ellipse.
Technodiamant guarantees the sharpness of their tools, both controlled and non-controlled waviness, at a magnification of 600x.
In order to avoid touching the radius after finishing the tool, we have also developed a completely new optical measuring system. This system makes touching the radius with a measuring device redundant. It is possible now to precisely measure the waviness of the radius and the radius itself without any contact.
It is possible to measure any size window of tool sweep; normally the size of the window is 100° or 120°.
Technodiamant also has the possibility to assure, by means of an interference microscope, that the table of the diamond is free from all polishing grooves. This is of major importance, because grooves will affect the sharpness of the cutting edge.
RIGID SHANK or INSERT STYLE TOOLING
We can provide the diamond mounted onto a traditional solid shank made of molybdenum or special dense “chatter-free” tungsten, or we can provide the diamond mounted onto virtually any type of carbide insert. Our standard inserts that we provide are 55 degree (DCMW070204) or 35 degree (VCGT110302) .
All Technodiamant Controlled Waviness Tools are supplied with a measurement report.
Extensive tests on various materials have proven the superb quality of our tools.
