CHUCKS

Our Asper-TiN chucks, are machined on special tool steel, a material that is previously defined according to the results of a technical visit to the plant in order to determine the characteristics of the work that it is done so we can optimize the substrate material (steel) to which we will apply an anti-wear coating of Titanium Nitride (TiN), Chromium Nitride (CrN), Aluminium Titanium Nitride (AlTiN), Chromium Titanium Nitride (AlCrN) or an specific nano-structured coating that will prolong the lifetime of the tool. For tools subject to high corrosion, we suggest our Chromium Nitride (CrN) coatings.

Our chucks are characterized by a low friction coefficient (<0.4) giving high tensile strength avoiding the picking up of particles and thereby achieving a dramatic reduction in maintenance profiles and edges reducing the number of periodic replacement and restocking expenses.

Our ASPER tools are manufactured in martensitic stainless steel, chromium lebeduritic steel or cobalt-chromium alloy each of them provides a high resistance to mechanical wear and corrosion based on the desired application.

Each of our chucks are coated with a thin film of between 3 to 6 microns of Titanium Nitride (TiN) that will prolongs its lifetime up to 4 times compared to uncoated tools, which translates it into net savings in the range of 40% to 60% in rectification and restocking expenses, as well as in production-line-stops, maintenance and replacement costs.

We are very strict in monitoring the quenching and tempering of our steel pieces, ensuring a component hardness in the range of 52-60 HRC depending on the work to be performed, keeping the characteristics of toughness and high resilience of the material and compensating the hardness and the reduction of the friction coefficient by the application of TiN coating, reaching a superficial micro-hardness of 2,300 to  2,400 HV (Vickers) which it’s approximately 86HRC, optimal for achieving a high level of performance, productivity and durability that only ASPER tools can provide.
