Spark Erosion Project – Drain Hole into Super Duplex Pump
Project Name: Spark Erosion of Drain Hole into Super Duplex Pump
Type of Work: Housing /Chemical
Client Requirements: Cheshire Wire Erosion was asked to spark erode a lateral “drain hole” into an Inconel pump impellor housing.
This material is known as a superalloy as it is oxidation-corrosion resistant so well suited for use in extreme environments when subjected to pressure. However, this does mean that it is a tough material to machine conventionally. The project was made more complicated due to the angle required and position. In addition, the client requested a very quick turn-around because of production down time.
To complete this project, we used our Sodick AD35L which allows for optimum performance at high speed and rapid acceleration.
Work Carried Out:
Based on the capacity of the Sodick AD35L the drain hole was too large to be spark eroded in a normal submerged condition. As a result, the metal was machined with the door of the Sodick AD35L open and we adapted to the situation by creating a reservoir using a metal plate and modelling putty, as you can see from one of the photographs included. We were then able to carry out the machining. The project was completed on time and with a very satisfied customer!
The type of work involved in this project is not undertaken very often due to its unsafe characteristics, however we were willing to carry out the project based on customer necessities.
While using the latest innovation in technology, we must, at times, adapt this technology and machinery to accommodate a project. This is all part of the professional service that we offer at Cheshire Wire Erosion, we tailor our services to meet your needs. We can improvise and adapt, using the cutting edge EDM machinery we have invested in to ensure a project is completed.
