Forming Oils from BECHEMCustomized products for forming technology
There are two main challenges in cold forming on modern multi-stage presses:
the design of certain types of presses does not allow for the separation of cold forming oils (KFP) and machine oil. In this case, the low amount of high-pressure additives in normal machine oil means that their use in cold forming leads to greatly increased tool wear.
Even in presses that separate machine, track, and cold forming oil, oil mixtures can never be completely prevented due to leaks. This is particularly a problem in older machines. It dramatically reduces the additive level of the cold forming oil as well as the performance as a result of dilution (mixing), while the viscosity increases (greater drag-out losses). This ultimately makes a premature oil change unavoidable. BECHEM offers an optimum, tried-and-tested solution with its multi-function oils concept, which perfectly supports forming as well as machine lubrication.
The use of a single oil eliminates the mixing issue. This ensures a consistently high additive level together with a constant viscosity.
Countless practical tests using BECHEM multi-function oils on four- and five-stage presses (1,000 hours and more) resulted in identical or better tool lives compared to conventional lubricants. In each case, the oil change intervals were significantly extended (50 to 100%). The special additives in BECHEM multi-function oils also make them suitable for forming non-ferrous metals.
In cold forming, (preferably pretreated) workpieces made of metallic materials (e.g. steel, stainless steel, non-ferrous metals, aluminum) are pressed into a defined shape by applying considerable forming forces. This may require several forming stages, depending on the geometry of the finished part and the material.
The extreme surface pressures between the tool and the workpiece require high-performance forming media capable of creating high-pressure-resistant layers during the process to prevent the tool from prematurely wearing, seizing or even breaking. For decades, users, machine builders and tool makers have been working closely with developers to create new forming media, setting the standard for high-performance cold forming oils.
An optimized forming medium enables efficient production processes.
