Because there are lots of mass finishing machines suppliers in the markets, choose the right machine suitable for your use is important. Make sure that you check a list as follow so you can get the most out of your machine, as this is an investment for a long term.
1. Mass Finishing Machine Movement
Appearances can be deceiving. So don’t be fooled that all machines are the same just because they look similar. Always test the machine and it’s processing ability before you buy! Test its amplitude; see how regular the movement is. Also testing if the machine always runs consistently driving the same way.
2. Control System
The less you pay and the less you are going to get. For control system, we typically install with timer and fuse (overload protection and overheat protection). VFD or we call Speed converter as well as an option for variable speed control. Besides time relay used to keep the record of time in case of electricity shut off.
Because mass finishing machines design to produce a consistent result, so we can only do that when we have a controlled process.
3. Protection from Failure
Many linings look the same color and they claim to use the same raw material yet, in reality, the differences can be considerable. How thick is it, where is it testing and is it the same all over (and how we make the checking)? How is the lining applied and how does the manufacturer ensure that the lining has no defects (pores) that result in premature failure and necessary replacement costs and inconvenience?
4. Motor Power
The amount of energy being put into a machine as well as how that we use the power is vitally important to achieve finishing results. Just because two machines may have similarly sized motor interns of KW doesn’t necessary means that they will perform the same
5. Flexibility and Adaptability
Linked to the power and the speed, controlling the movement in the machine via eccentric weights is a critical factor. One thing we know is that in business as in life, things will always change.
Materials are constantly being developed, manufacturing methods updated and tooling is always evolving. As a result, the machine you invest in will only fully return its investment when it has the flexibility to finish the parts you make tomorrow as well as those you make today.
6. Variable speed control
Single wound motors are cheap to fit but not really suitable for vibratory finishing applications as typically unloading and rinsing requires that the machine operating at different speeds. Whilst converters can be fitted to control speed changes it is often a case of making something fit rather than it having been designed with the best result and operating techniques in mind.
7. Longevity of Mass Finishing Machines
Bearings are critical in a mass finishing machine. When standard bearings are using, they will fail within a relatively short time frame. And each time when they need replacement, there is the cost of buying them, removing the old ones and fitting the new. This is invariably where a cheaper machine over a relatively short period of time becomes more expensive via the cost of ownership.
8. Strength and Durability
Check how heavy a machine you are considering is. And get the machine weight, not the machine and ancillary equipment (lid, control panel, dosing pump, etc…). Usually, you will find something costs less because the manufacturer makes it cheaper.
