Metal Work is an Italian company specialised in the production of pneumatic components for automation systems. We currently market five different product ranges: actuators, valves, FRL units, fittings and handling components, all of which appear in our 1400 pages catalogue.
ELECTRICAL LINEAR ACTUATORS
Electric axis without screw piston rod, with V-Lock interface.The cylinder frame is made of anodized extruded solid aluminium, whichgives the cylinder optimal torsional and flexural rigidity. The typical V-Lockdovetail is provided on three sides of the channel for easy fixing with QSelements.The carriage features an interchangeable fixing interface plate, which isavailable with V-Lock axial or V-Lock orthogonal ports or in the blank typefor custom solutions.The carriage is driven by two sturdy pre-loaded ball recirculation bearingsthat ensure great accuracy of movement. Threaded holes for the lubrication of the guides and ball recirculationscrews are provided on both sides of the carriage.The carriage is driven by a system consisting of a hardened and temperedscrew and a ball recirculation lead nut. The screw is pre-stressed with anelastic load device by means of cup springs in order to reduce vibrationand hence noise level and the useful life of the system.A series of slots for the fixing of magnetic sensors are provided on the twosides of the liner.Various BRUSHLESS and STEPPING motor drives are available with optionalmotor brake and/or built-in encoder.The cylinder can also be supplied without motor drive or, on request, withmodules for interfacing with motors from the trade.The motors can be installed in line with the liner or geared using toothedbelt transmission gears
ELECTRIC ROD-STYLE ACTUATORS
An electric cylinder with a connection interface in accordance with ISO 15552.The piston rod extension is controlled by a system with a hardened screw and recirculating ball screw nut. The piston has a guide strip calibrated to reduce to a minimum play with the barrel and hence vibration during ball screw rotation. The cylinder can be equipped with a built-in non-rotating system featuring two opposing slides that run in separate longitudinal slots in the barrel. The piston comes with magnets and the barrel has longitudinal slots for housing sensors. The piston rod has increased outside diameter and thickness to make it extra rigid and more resistant to radial and peak loads. A system for greasing the screws is included. Numerous standard accessories for pneumatic cylinders, can be used for mounting the cylinder. Accessories made of aluminium, or made of steel for heavy-duty operations, can be used.The motor can be selected from an optimised range, which encompasses both STEPPING and BRUSHLESS motors.
• Dual-acting parallel gripper for internal and external clamping.
• Anodized aluminium alloy body and tempered steel jaws.
• Bottom or side fixing.
• All sizes come with magnets and sensor slots
EB 80 is defined as an electro-pneumatic system as it would be simplistic to use the term “solenoid valve island”. In effect, a single assembly can combine solenoid valves of all types, multi-position bases, pneumatic and electric supplies arranged as desired in a system, digital or analogue input or output signal control modules and much more besides. The EB 80 system is protected by numerous patents and utility models, which enhance the most innovative design solutions. The possible combinations are endless, but the most amazing thing is that they can be obtained using a small number of basic components.
In order to achieve this objective, a single size of small yet high-performance valves to cover the vast majority of applications was conceived. A single electronic control unit is provided when supplying 12VDC or 24VDC valves with multi-pole cables or with a field bus for each protocol. All EB 80 versions come with an efficient diagnostic system. The EB 80 catalogue consists of a first overall introductory chapter followed by a chapter for each subsystem.
NSF H1-certified grease is used to lubricate the valve spool and seals.
