A new numerical control milling and boring machine ram deformation compensation method

The floor milling and boring machine is a super large heavy machine tool, which is mostly used for gravity cutting. When the machine ram is extended or the attachment is added, the center of gravity of the headstock is moved forward due to the action of gravity, and the ram is lowered. The only change amount is that the amount of ram extension is different, and the degree of bowing is different. If this situation is not improved, it will seriously affect the machining accuracy of the machine tool. In the floor milling and boring machine, in addition to the ram, the boring shaft itself

Electric Butterfly Valve

Butterfly Valve With Electric Actuator, Electric Actuator Butterfly Valve, Electric Actuated Butterfly Valve


BRANDO's range of electric butterfly valves, which are used to control the flow of a media remotely. They can have either a lug or wafer connection style. The actuator either opens or closes the valve with an electrical current, but doesn't require energy to stay in that state. The butterfly valve has a disc that rotates with the actuator to open or close the butterfly valve. The butterfly valve design allows for good sealing properties, durability, and reliability for your application. Electrical actuators are easily installed and wired into an existing system. There are various housings, seals, and sizes of electrically controlled butterfly valves to allow you to find the right one for your application.
