Job Description

EDM Machinist

EDM Machinist 

FlexTrades Travel Contract Assignment 3 months, in California. We provide Hotel, Per diem, Travel Pay, over time

• Setting up and operating CNC EDMs – both wire and sinker.

• Machines run on an XY plane and then a rotary axis. 

• Responsible for two machines at a time. 

• Setup entails replacing the spool/wire, setting up electrodes, and understanding the importance and testing of deionized water. 

• No built-in sensing or intelligence systems are in these machines. 

• Wire tension is set during the set up but it’s infrequent that wire is changed and that’s not done by FlexTrades technicians. 

• Metals: nearly all 440 grade stainless steel as well as some beryllium copper and other stainless grades. 

• Bars range from 4mm in diameter to 1” in diameter. 

• Parts: components for electro-hydraulic pressure & flow control valves. All parts have been cut on the CNC Swiss machines and then heat treated prior to coming to this area. 

• These are REALLY small. The smallest part has a diameter of .080” (80 thousandths of an inch) and are only 1/8” long. Holes are very small too at .004” diameters (4 thousandths of an inch). 

• The parts are VERY delicate, and the tools used to machine these are very delicate as well. Even coolant on the drilling tool could break it. 

• Quality: parts are basically all rectangular in nature so there isn’t a lot of inspection but at times a Tool Maker’s Scope will be used to find the edges of a slot created by the EDM machine.
