234 is equipped with a frequency inverter -with vectorial flow technology - that enables to control three phase motors although the machine is equipped with one single phase motor 220 V. 
This technology gives exceptional power to the machine both on the polishing head and on the plate. Speed variations are very precise, torque and speed are constant whatever the load. Acceleration is progressive, the two directions of rotation are available (head and plate) and the machine has a thermal security in case of prolonged overheating. 
 
MECATECH 234 is a range of robust, powerful and reliable polishing machines, incorporating the most advanced technologies for an easy use and simple maintenance. Its plates Ø 200 and 250mm, associated with the TC 10, TI10 and TCI 10 polishing heads give the best polishing results on all types, sizes and numbers of specimen. 
 
Thanks to the LCD touch screen which can be positioned on the left or right side of the polishing machine, it is very easy to create or modify a polishing method, to store it (memory capacity: 100 methods) and to manage the functions of MECATECH 234. During the progress of the cycle, the current operation can be displayed as well as the following one or the previous one, allowing the operator to anticipate consumables to come. 
 
The powerful and quiet motors controlled by a frequency inverter and a Poly-V belt transmission, completely mounted on ball bearings, dispense adjustments of tension and give silent functioning to MECATECH 234 in a laboratory environment. 
 
The force applied on the samples is controlled by a proportional electronic valve giving a total precision. MECATECH 234 calculates automatically the force to be applied on the sample, whatever the number or samples, avoiding any risk of mistakes to the operator. The force applied to samples is reduced to the starting up and to the stop of the cycle for an optimal quality of polishing. 
 
The flow of lubricants or abrasives is controlled by micro- peristaltic pumps allowing a precise dosage, generating substantial savings as well as perfect reproducibility, whatever the user is. 
 
The automatic locking of the polishing head when the cycle is starting, avoids every risk of error due to the use of a handle. The lifting of the polishing head at the end of the cycle facilitates the ergonomics and the loading / unloading of the plates or single samples. 
 
The 230 V single phase power supply enables to set up the MECATECH 234 where the user wants, without constraints of specific connections.
