If you’re having trouble finding sinker EDM flush pots for sale, don’t get too frustrated, as you’re not alone. Commercially sold EDM flush pots are typically difficult to find because they are commonly made and customized for specific needs. However, the good news is that flush pots are easy to manufacture, with variations limited to the external size and internal opening based on the specific needs or application. Provided below is a simple drawing that outlines the basic construction of a flush pot.
Flush pots are usually hooked up to the machine’s auxiliary flushing or suction connections that are located in the work tank. Depending on the machine and applications being performed, you may find it useful to add an in-line value to fine-tune the fluid flow.
Flush pots can also be highly customized for specific and exact needs, such as punch machining (workpiece is held in the Z-axis), as this process uses an electrode plate mounted on the worktable. Depicted below is an example showing a custom electrode plate with three stations mounted to a custom flush pot with three separate individual flush cavities.
Q: Do Makino sinker EDMs have an option for a programmable flush manifold?
A: Yes, Makino does offer two different options for programmable flushing, which can be controlled (on/off) in the NC program. Makino offers a three-port and a 10-port programmable flush manifold that supports continuous flush and intermittent flush modes. Provided below is the NC program code format:
M_ _ L_ _ P_ _ _
M40 > Valve #1 ON
M41 > Valve #2 ON
M42 > Valve #3 ON
M43 > Valve #4 ON
M44 > Valve #5 ON
M45 > Valve #6 ON
M46 > Valve #7 ON
M47 > Valve #8 ON
M48 > Valve #9 ON
M49 > Valve #10 ON –
L0 > Continuous Flush Mode
L1 > Intermittent Flush Mode –
P (2~500) > Intermittent Flush Timing in Seconds –
Looking for the best source to purchase flush lines and flush line manifolds? While there are a number of different sources to purchase flush line components, Makino recommends Loc-Line® brand products. These products can be purchased from many industrial supply sources. Loc-Line’s magnetic base manifold kit (Loc-Line part #40463) is a popular and useful kit, and the company has also recently released a new ProStream series of stainless steel flush nozzles. If you’re in need of flush lines and flush line manifolds, we encourage you to look into Loc-Line.

Are you experiencing leakage from your EDM machine’s canister filter? Fortunately, there may be a very quick and simple, low-cost solution.
When replacing canister-style filters (outside-in filtration), it is important to lubricate the new filter O-rings on each end of the filter with a di-electric grease or petroleum jelly to prevent damaging or rolling of the O-ring. This is a process that can be easily overlooked during operator or maintenance personnel’s hectic schedules. If left unaddressed, however, the by-passing or leakage of the filter may result in damage to the machine. As such, be sure to address the issue quickly to prevent any further, and potentially costlier, problems in the future.
