The use of servo-motors in punching-bending technology has opened up new production opportunities. Although classically driven machines are able to operate at high speeds and produce correspondingly large unit quantities, the product diversity is limited. In addition to this, mechanical machines can only be converted at high expenditures. The maintenance work is also time-consuming, as hoses must be refilled and inspected. In contrast, bending machines with servo-motors, such as the X2000 NC produced by Schmale Maschinenbau, enable considerably more flexibility with regard to product diversity and much lower maintenance requirements. Machines driven by servo-motors also allow for a changed customer logistic strategy.
While companies previously relied on large warehouses designed for long-term storage, today’s inventories are generally kept for shorter periods to save on costs. The consequence is orders of smaller quantity, which need to be completed on short notice and to which the producer must react with appropriate quickness.
Schmale Machinenbau - Innovations with servo-motors
With the launch of its X2000 NC, Schmale has for the first time brought a completely servo-electrically driven system to the market. The model has a series of benefits as opposed to mechanically or hydromechanically driven systems, not least of which being the installation of servo-motors. This makes the X2000 NC , X2000 BB and X2000 BK models with servo-motors considerably easier and faster to program than systems purely operated by mechanics. Add to this the fact that servo-motors ensure smoother handling of the materials. As a result, this technology also positively affects the quality of the final product. Setup time, cyclic output, and energy efficiency are extremely favorable for production systems with servo-motors which operate completely without oil. Machines with servo-motors also enable the integration of pre-existing mechanical tools. The X2000 BK produced by Schmale Maschinebau is also able to operate standard Bihler tools. This increases the range of possible manufactured products even further and reduces the conversion time many times over. Small batch sizes can also be realized easily and with low time and cost expenditure.
