Pneumatic system - Import export

Pneumatic timers are used for the precise time control of pneumatic signals in pneumatic circuits or systems. The pressure-independent function of time delay starts when pressure is applied to the control port. After the pre-selected time is elapsed, an internal 3/2 way valve is switched. The pneumatic timer is reset to the initial condition if the control port is vented for at least 300 ms. The adjustable time delay depends on the chosen version and amounts between 0.5 and 180 s. Due to its design the control pressure level must not be below working pressure level. As a result of the fire-risk evaluation according to EN 13463-1, the pneumatic timers are not subject to ATEX regulations. This means they may also be used in explosion hazardous areas as defined in IIG/ IID.

The Lapmaster Wolters Model 20 is a bench mounted unit with a heavy duty carbon steel weldment base. The model 20 is ideal for engineering workshops, where flatness and finish are of prime importance. It is equipped with a 508mm diameter serrated lap plate, manufactured from Grade 300 grey cast iron to ISO 185(2005) as standard. In-shop lapping reduces costs of component processing and equipment maintenance programs. Worn parts are reconditioned and salvaged, thus eliminating scrap. The pneumatic lift version of the Lapmaster Wolters Model 20 is based on the open face machine. Pressure weights are attached through self-aligning bearings to the rods of the pneumatic cylinders. The cylinders are mounted on a framework located over the lap plate on an upright column. The primary function of the pneumatic arrangement is to permit loading and unloading to be carried out without the need to lift pressure weights manually.

The Peter Wolters AC 2000 double-sided batch processing machine is designed for high-precision series production of workpieces. Thanks to its modular design, the AC 2000 can be used as a fine grinding, lapping, honing and polishing machine. Like all machines in the microLine© series, the AC 2000 relies on proven core components such as the high-precision pneumatic loading system, the non-contact micro-measurement control, the powerful drive technology and the PC-supported machine guidance. The software used for this is specially developed by Peter Wolters and enables complete menu-driven and intuitive operation of the machine. For optimum access to the working area, the entire upper part of the machine can be swung out.
