Variable-speed drive solutions: Less current, less noise, less costs.

Variable-speed drives connect standard components from hydraulic and electric systems to form customized, intelligent and cost-efficient systems. What is the savings potential compared to simple hydraulic solutions, and what should be considered for dimensioning? The hydraulic drives market is changing. Instead of dimensioning for corner power, machine manufacturers and users are more and more looking

Stay cool – efficient cooling system for the railway

Fan drives in rail vehicles improve energy efficiency and require less space Manufacturers of rail vehicles require cooling systems that are more efficiently controlled in order to comply with new exhaust gas emission limits and reduce energy consumption. In order to achieve this, diesel engines air intake and electrical main drives have to maintain ever

Press with IoT turbo? Connecting presses: get off to a flying start

With IoT technologies (Internet of Things) and digitized components, it is not only possible to satisfy central customer requirements more quickly, more intuitively and at lower cost. New business models such as pay per use are also opening up opportunities for extra revenue. At the EuroBLECH 2018, Bosch Rexroth will show how this works in

IoT and Forming Technology: Connecting Presses – why and how?

Connectivity with IoT technologies (Internet of Things) enables press manufacturers to face up to the typical challenges of forming in a way that is more cost effective, faster and more intuitive than classic automation tools. Digitalization available across a range of topologies is the basis for new business models such as availability as a service

New hydraulic-design for presses

New drive concept makes hydraulics economical and intelligent By means of variable-speed pump drives, new, patented hydraulic axes simplify the design and control of presses of any kind. They considerably reduce the power consumption as well as the required oil quantity by up to 90 percent. To this extent, the control technology of a valve

Additive Manufacturing – An industrial revolution

Additive manufacturing has come of age and we’ve been enthusiastically involved in a project that’s bringing it several steps closer to maturity. Additive manufacturing (AM), or 3D printing as it’s often known, first emerged some decades ago, but in recent years it has started to enter the mainstream. The latest techniques and supporting technologies mean

Improving OEE as Pay-per-use? Yes!

Philipp Osterwalders post on “how to connect a machine in just 4 hours” is an impressive report on pace in Industry 4.0 projects. The use case he shared with us is on Filter Monitoring. The implementation site of the project is at Bosch Rexroth plant in Homburg. About 25 percent of failure costs for long-term

Hydraulics with IO-Link: Reduced effort, high value

In almost all industries, machine users require increased flexibility for production means for small batches and continuous diagnostics of all actuators and sensors to increase availability. In addition to this, there is quickly increasing horizontal and vertical connection of machinery and systems for Industry 4.0 applications. The open standard IEC 61131-9, IO-Link, fulfills these requirements

Servo Presses

Energy management for Servo Presses

Energy management is a crucial part of every servo press. At the EuroBLECH 2016, Bosch Rexroth demonstrated electro-hydraulic drive concepts with innovative potentials in this field. Within our cooperation with Bosch Rexroth, we have created an augmented reality application illustrating the groundbreaking energy concept of the forming machine. This way, we demonstrate the energetic coupling
