Purpose: Progressive miniaturisation generates necessity of micro-parts production also on the field of metal forming. At present small pats are produced with a big presses which were designed for manufacturing much bigger products. Further miniaturisation will not make possible to keep sufficient tolerances of products manufacturing with these standard presses. Design/methodology/approach: It is suggested to set up special technological lines for micro-parts production. Such lines would consist of micro-machines based on piezoelectric actuators. The recent development of that kind of actuators assures even up to several kilo-Newton forces and movement accuracy theoretically in atomic scale. As a step for building the line, a micro-press with piezoelectric drive is being constructed. Findings: The constructed press can work with direct actuator and can be also equipped with simple mechanical movement amplifier. Micro-indenting, micro-pressing and micro-backward extrusion were successfully carried on the press. Examples of simple sequentional and incremental micro-forming processes were also performed. Research limitations/implications: Equipping Micro-press with additional devices like x-y or x-y-z table positioning, automatic clamping and supplying systems etc. will able to extend its application to wide range of microforming processes. Practical implications: Micro-press in intention is going to be a part of industrial micro-lines for micro-product. Originality/value: The idea of building micro-parts with micro-machines standing as production micro-line seems to be quite natural but so far not realised. Presented Micro-press with original construction is another step to put this idea into reality.
