Takatori Multiwire Saws are designed for years of high-volume production with many customers are running their machines around the clock.
The machines require regular attention to maintain this high level of productivity and here are a few tips on what to do.
- GTI Engineering and Service Visits
Every new technology purchase has a learning curve; think about a new computer, a new phone, anything new. When you are new to your wiresaw, the best way to take advantage of Takatori’s great technologies is to have regular service visits scheduled. Training is included with every new Takatori wiresaw, but spending additional time with an experienced GTI engineer after you’ve had some time to work with the machine is always valuable. These visits can include preventative maintenance, training, process advice and simply answering the myriad of questions that always arise as the machine is put into production.
- Keep Your Machine Clean
Cleanliness is always important in the manufacturing area but don’t forget the inside. Saws don’t really require a lot of skilled trade maintenance support on a regular basis; however, it is important that the skills of a trained operator include cleaning the interior of the saw, particularly behind the wall where most of the saw’s mechanical systems are. Not only does this avoid problems, it also makes working inside the machine much easier (and more pleasant) if a problem occurs that requires access to the innards of the tool.
- Use the Recommended Pulley Bearings
Yes, you may find bearings that last longer, you may also find cheaper bearings, but they will not have the same internal fit. The wire management system on these machines is finely tuned to minimize wire breaks. Putting non-standard bearings into the pulleys may seem like a minor change, but it can lead to more frequent wire breaks. Putting thousands of dollars of material at risk to save a few dollars on pulleys is not a good idea.
- Tune Your Slurry
If you’re looking to increase productivity, don’t just look at speeding up the wire to increase cutting speed, look at your slurry. All mechanical parts have an expected life span and increasing wire speed can negatively effect the lifespan of spindles, bearing and pulleys. To speed up, consider changing the abrasive rather than the speed. With slurry saws, data shows that increasing spindle speeds to slice quicker is not as effective as grain loading (increasing the amount of cutting ability of the slurry). Ask a GTI engineer; he can help you optimize your process.
- Check Your Wire Reels
Before putting them on the machine, check your wire reels for wear, damage and debris. Wire reels are made to a close tolerance. If the distance between the edges becomes larger (wider), you can adjust the traverser to the larger width and reduce the tension of the wire coming onto the reel. Takatori has advanced the software so the software you slice with doesn’t have to be the tension you wind on your collect reel.
