UK-based fluid and energy methods producer Domin has enlisted Renishaw for the event of a few of its merchandise. Specifically, Renishaw has discovered a extra environment friendly means of manufacturing Excessive-performance direct drive servo valves. Because of this, the valves are extra highly effective whereas being far cheaper and sooner to supply.
Domin and Renishaw have been working in the direction of enhancing the manufacturing course of for the L, R and T sequence valves by utilising RenAM 500Q. Because of this, they’ve decreased the manufacturing time from 5 hours to 1 hour. The fluid-power methods use liquids or gases to generate and transmit vitality by making them exert stress on a piston. Thus, the fluid motor creates a torque which units the fluid in rotary movement.
The servo valves regulate this course of performing as management parts, turning alerts into stress. Fluid methods can outshine mechanical or electrical drives as they’re extra compact and might last more. They will additionally present extra exact management over the method. Such methods are underneath use in aerospace parts and excessive pace cars like F1 vehicles, and even in industrial energy vegetation. The brand new drives are 25% extra highly effective however solely 1 / 4 of the dimensions whereas being a 3rd of the fee.
Renishaw’s Steel AM Know-how
The corporate states:
“To resolve the inherent challenges of the rotary to linear valve idea, Domin engineers have had to make use of the complete design freedom afforded by AM. It has resulted in a novel patented idea utilizing a flexure throughout the AM spool to accommodate the lateral movement from the curler bearing drive. The result’s a valve with elegant simplicity utilizing the minimal of element components. Complexity is restricted to some miniature AM parts.”
Additive manufacturing additionally provides the corporate the chance construct complicated components, freed from tooling and with minimal operations and meeting. Additionally they use far much less materials with such an environment friendly machine, sporting much better materials utilization to waste charge than subtractive strategies. Steel AM methods additionally enable for higher insulation, enhancing the metallic membrane that gives a fluid barrier separating the rotating components of the valve from components of motor and transducer. The configuration removes the necessity for rotary and inside excessive stress seals.
Renishaw’s Quadlaser system has discovered a house in many various firm’s workflows. Sandvik, for instance, additionally has been utilizing a number of RenAM 500Qs at their manufacturing services. It’s straightforward to see why, as it will probably produce at excessive speeds with a deposition charge of 150 cm³/hour most.
