The new ETH electro thrust cylinder succeeds in setting new standards in power density and lifetime of electro-mechanic linear actuators

The well-known series of ET electro-thrust cylinders, which is widely used in thousands of different applications has been completely redesigned and enhanced. It is now unrivalled for power density, in other words high forces and small frame sizes.

The ETH is a convenient replacement for conventional cylinders due to its pneumatic ISO flange norm (DIN ISO 15552:2005-12) conformity as well as being optimised for safe handling and simple cleaning. Any limit switches and cables can be hidden in the profile and a useful anti-rotation device is integrated into the actuator. This new design has greatly increased lifetime (up to factor 5), and reduced maintenance costs thanks to an integrated re-lubricating hole in the cylinder flange and although very powerful has much reduced noise emission.

To achieve precise motion, positioning, setting and actuating the electro thrust cylinder has high mechanic efficiency up to 90 %, stroke lengths up to 1600 mm, high traction and thrust force up to 25,100N. The repeatability of the ETH is up to ±0.03 mm with a speed up to 1.7 m/s. The range has toothed belt drive (for parallel motor mounting), has many different screw pitches for thrusts from 5 to 32 mm/rev.  As a package there are predefined standardised motors and gearbox flanges for simplified selection and therefore available directly all from one source. Three different protection classes are available, as standard IP54 with galvanised screws, then as options is IP54 with VA stainless screws, and IP65 only on request.

The typical fields of application for the ETH are packaging machines, food/beverage processing, material handling, feed systems and as a servo cylinder in the wood and plastic working industry. In the textile industry it can be used for tensioning / gripping textile fabrics, for vertical actuators loading machine tools and in the automotive industry for transporting and feeding components. Further applications include testing equipment, laboratory applications, pressing, valve and flap actuation.

Customised products and services (CPS)

We have seen increased requirements for customised products and services, so we are pleased to announce the upgrading of our CPS service

Customised products and services (CPS)

Do you need to reduce your paperwork, cut your vendor base, lower costs or simplify production?

For manufacturers there is the ever-present pressure of ensuring components are ready for production on time. This involves taking products from stores and carrying out modifications before returning them to the shelf ready for later use in the build process. It means stocking numerous components, additional drawings and administration, assembly work which may contain errors and is of course expensive.

What is really required are products delivered from your supplier, ready for installation when you need them!

To make your life easier, Micromech is ready to undertake these numerous modifications. We produce special shafts and flanges, add cables and connectors to motors, paint, fit gearboxes and encoders, as well as producing special adapters for fitting motors to actuators and brackets for assembly into multi axis mechanical systems.
Using our in-house technical expertise, we modify ‘supplied’ parts to fit existing systems, whether it be a simple motor cable, or gearbox flanges or any other component. So not only do we supply your motors, drives and controls, we offer the following additional services:

Mechanical:

  • Finished parts – to your specification, this could include painting, spraying, coating, part number marking, labels and environmental protection
  • Machined modifications – this includes flanges, special adapters, keyways and special shafts
  • Assembly of components – fitting together brakes, clutches, couplings, adapter plates, gearboxes and even your own free issue parts
  • Completed assembly test – then supplied with appropriate documentation

Electrical:

  • Assembly – fitting motor connectors, extending motor leads, sleeving motor leads, rack assembly, etc
  • Modification – PCB changes, leads/cables fitted to PCB’s, vacuum preparation

Electronic:

  • PCB –  design and development, motion control system build
  • Software Engineering – customised control functionality and communication solutions

Note: all these products will carry the customer’s part number (if required) and our own unique SP number

Food for thought – Auger filler for powdery products

More success stories from the most diverse applications which partners Micromech Systems and Parker has been supporting for food processing equipment and packaging machinery manufacturers.

Parker - Auger FillerAuger filler for powdery products

The use of auger fillers is for applications where precise dosing of powders and granules is preferred and essential. A machine manufacturer wishing to create new market potential in the area of semi-automated individual fillers faced the problem that a solution incorporating a servo driven dosing auger and separate PLC was far too expensive. They wanted both a cost-effective modular solution for semi-automated systems as well as for fully automated dosing modules requiring integration into filling and flow wrapping machines. They also demanded component reduction and a simple modular design.

Thanks to a servo drive solution tailor made for the application offering a completely integrated control system meeting the requirements of IEC 61131-3 and PLCopen, it was possible to eliminate external controllers and I/O modules and to reduce total system costs. Furthermore, the process focussed control integrated into the drive allowed for faster response times of the mechanical shut-off slide and thus delivers better precision. It was found that running at 80 strokes per minute with a spread reduced by 0.2 g resulted in more than 3300 kg of product being saved annually over a two shift operation. By connecting an operating panel to the servo drive the module could also be used as a standalone version. Control via I/O or fieldbus options allowed for integration into complex machine structures and thus this decentralised servo drive reduced costs and enhanced precision.

In automatic high performance filling systems the mechanical shut-off slide can be optionally replaced by a tubular plug and play linear motor actuator, which achieves more than 90 strokes per minute with high precision and maintenance free operation. Here again the servo drive provides the complete control technology, which results in additional savings.

This advanced is fulfilling the machine manufacturers desire to open new markets and also their existing customers are delighted with the outcome, much higher production and simple to use stylish machine.
