Frequently Asked Questions
Q: What are the differences between a wet machine and a dry machine?
A: The benefits of a wet sander are: a minimal risk of a fire, increase in belt life, a higher quality of finish in less steps with minimal heat generation, airborne dust is non-existent, and parts exit the machine free of sanding debris which reduces wear on press brake tooling. When using a dry sander: mixing of metals can lead to catastrophic thermal events (fires and explosions), the sanding process can generate enough heat to warp parts; but dry machines are usually less expensive, require less maintenance, and are easier to clean.
Q: How wide of part can I run?
A: Timesavers offers a wide range of options from 9” wide to 64” wide and beyond. These sizes vary greatly depending on what machine configuration is required for your application.
Q: What is the shortest part I can run through a Timesavers sander?
A: The shortest part length is determined by the distance between the infeed hold-down rolls and the outfeed hold-down rolls. These distances vary from model to model, however, there are some alternatives:
1) Building a fixture to hold/group small parts in a way to meet the minimum part length.
2) Leave the parts tabbed together and run the full sheet after punching or stamping.
3) Use a vacuum bed conveyor.
4) Use a magnetic conveyor bed (ferrous parts only).
Q: What is the purpose of adding coolant to the water in a wet machine?
A: The coolant, when mixed with water in the correct proportion, protects the machine and the parts being run from rust and corrosion. The coolant also acts as a grinding aid to reduce heat generation, and increase abrasive belt life.
Q: Which brand of sanding belts does Timesavers recommend?
A: Timesavers does not recommend any specific brand. We do, however, recommend that a belt of good quality from a major manufacturer be used. Abrasives are more than just rocks glued to paper; splice quality and belt construction are a huge factor in belt life and producing a quality finish.
Q: How much material will I remove when using a belt sander to deburr and finish my sheet metal parts?
A: This will all depend on what process you require. Our Rotary Brush machine can deburr cladded aluminum parts without damaging the protective cladding, and will not even remove printed markings most of the time. On the other end of the spectrum, calibrating can grind away the entire part if necessary. During most deburring and finishing applications, the amount of material being removed can barely be measured with a caliper/micrometer.
Q: Is there any way to prevent parts from slipping on the feed mat?
Absolutely. Over time, conveyor belts naturally become glazed and slick due to oxidation, causing parts to slip. If you’re experiencing this problem, check your hold-downs to make sure they’re set correctly. Also, make sure a sufficient amount of force is being exerted on the parts to rule out pressure setting issues. Another potential solution is to grind the conveyor belt. Using an abrasive belt on the sander’s mat will refresh the grip of its rubber. However, it’s imperative to use proper procedures and precise belt settings when utilizing this tactic. You can also contact Timesavers if you want an experienced service technician to examine your machine and correct the problem.
Q: Can I increase productivity by running my sanding machine at higher speeds?
No. Processing parts at higher speeds typically necessitates higher horsepower, an upgraded frame and the implementation of additional sanding units. Pushing your sanding machine to do too much at once usually results in an inferior finished product. By running your Timesavers sander at significantly higher speeds than intended, you’ll see a marked decrease in finish quality. Boosting speeds too high can also result in shorter belt life and issues with effective stock removal. In most cases, it’s a better idea to invest in an additional sander (rather than pushing your current machine beyond its limits) when you need to increase your shop’s productivity.
Q: How can I increase the lifespan of my abrasives?
Even the highest quality abrasives can be quickly worn down by frequent or intensive use. Luckily, there are a number of strategies you can use to enhance their lifespan. The first and most important step in optimizing abrasive life is to ensure you’re using the proper mineral for each specific application. For example, ceramic abrasives are incredibly durable and offer some of the highest cut rates available, making them ideal for stock removal and other applications in which the grinding tool needs to last for a very long time. Ceramic aluminum oxide is also a perfect option when performing precision grinding and applying a fine finish to tough steels and alloys. By using the best abrasives for each job, you’ll substantially increase their lifespan. This same principle applies to the backings you utilize for each product.
Another simple and effective way to boost the lifespan of your abrasives is by staggering the components you’re sanding across the width of the belt. This tactic ensures the entire width of the belt is being used in equal measure, meaning that you’re getting full value out of each abrasive mineral (as opposed to just the center or sides). Lastly, if your application requires, be sure to clean your abrasives regularly. This simple process can be done in-house or professionally and can play a huge role in keeping your abrasives performing at peak levels for longer. If you’re having trouble finding the right cleaning products for your machine or need more advice on increasing the durability of your abrasives, then please feel free to send us a message. We’d be more than happy to help.
Q: What’s the purpose of your wet dust collection machinery?
As you know, deburring, finishing or grinding ferrous and non-ferrous metals causes metal contaminants to be released into the air. Regrettably, this dust can create dangerous thermal events when it isn’t contained, including fires and explosions. Our dust collection solutions use water to filter these hazardous particulates out of the air, which is much safer than using a dry filter/cartridge. They also have a low operating cost and are easy to clean, making them a natural choice for almost any dry metalworking application.
