Parts surface improvement
  • Q: What the max burr size that able to remove by vibratory machine?

    For hard metal burr size below 0.05mm or 0.002 inches can be removed by vibratory finishing machine. Very big scale or fins need to remove by sanding machine before mass finishing process.

  • Q: How long to finish my parts?

    Aluminum or brass parts deburring or edge breaking usually takes 30 minutes to 1 hour.

    Steel or iron parts deburring or edge breaking usually takes 1 hour to 2 hours or even more.

    Ball burnishing or polishing process for metals typically takes 30 minutes to 1 hour.

  • Q: How many parts to run at a time?

    The rule is: you can add as many parts as you can if you can accept the surface finishing quality.

  • Q: Why are my parts damaged?

    Media portion is less than actually required lead to parts-on-parts impingement.

    There are three ways to reduce damage:

    1. Adding more tumbling media

    2. Adding water level in a wet finishing system

    3. Load 50-60% for barrel tumbling machine and 80-90% for vibratory tumbling machine

  • Q: Why do my parts get dark?

    Three reasons may lead to parts getting dark.

    1. Choosing the wrong compound to lead to parts oxidation. You need to change the right compound.
    2. Not enough compound in the finishing machine.
    3. In the batch process, too much dirt and grease in finishing machine.

  • Q: Why my parts stick together?

    Thin parts tend to stick together during mass finishing. You can use BL-1 anti-sticking agent.

  • Q: How do I dry my parts?

    1. Vibratory dryer with corn cob absorbs water and dirt from parts.

    2. The centrifugal spin dryer is the most cost-effective for small parts

    3. Conveyor belt dryer for continuous production, suitable even for larger parts

    4. Rotary drum dryer for batch and continuous production and, suitable for medium-size parts

  • Q: Why are my parts not tumbling well?

    Bellow is the most common reasons:

    1. Check if you have enough media in the tumbling machine, not enough media in the tumbling machine decrease the rolling movement

    2. Check wire connection from motor to the power supply if it is correct. This sometimes happens if you don’t install the speed converter.

  • Q: How do I get my parts to lift up and onto the screen more effectively?

    1. Make sure your vibratory bowl is filled 80-90%

    2. If this not helps, add more weight on top of the motor.

Machine, media and compound
  • Q: How do I select a machine?

    Choose vibratory finishing machine for the big quantity parts general deburring and polishing.

    Choose vibratory tubs if your parts are huge or special size

    Choose barrel tumbling machine if you accept the long process time. Barrel machine is good for delicate parts.

    Choose centrifugal barrel machine if your parts are high value-added parts, and you don’t have the huge volume.

    Choose centrifugal disc machine if your parts are bellow 30mm length and have a very big quantity.

    Choose continuous feed-thru system if your parts cycle time less than 15 min.

  • Q: What type of media should I use?

    Ceramic media is for general deburring. Its formula range starts from aggressive deburring, light deburring to polishing. Ceramic media is for all most all metals, especially iron and steel.

    Plastic media is for soft metal deburring and smoothing, for example, brass and aluminum. Plastic media is ideal for plastic parts smoothing.

    Besides, we have steel tumbling media and other special tumbling media for a different circumstance.

  • Q: Why is my media wearing out so fast?

    Ceramic deburring media loss 1-2% by weight every hour in the vibrator. Porcelain tumbling media loss about 1% by weight every 8 hours in vibrator. Plastic media wear faster than ceramic media. Usually, media with heavier cutting power wear faster. Remember to add enough media in the machine, so that can create gentle flow and reduce media wear.

  • Q: Which compound should I use?

    For ceramic media and plastic media tumbling, we use LC-13 to facilitate the tumbling movement. For polishing aluminum parts we use HM-2. For polishing stainless steel parts we use HM-3. HX-0 is the cleaning compound, we can add it during the polishing process to remove the dirt. MC-8 is the rust inhibitor. We soak iron parts in the diluted MC-8 to protect from corrosion. Please consult our compound selector guide for details.

  • Q: How much media should I use?

    4:1 media to parts ratio by volume for the vibratory machine with separation deck

    3:1 media to parts ratio by volume for batch process tumbling

    If parts are very sensitive on surface hitting, increase media amount to an acceptable level.

Setting & Maintenance
  • Q: What voltage to choose for my machine?

    If you have a choice on voltage, choose 460V (3 phase) instead of 230V (3 phase). This will cut your amperage draw in half. 110V single phase is the last choice because of no grounding.

  • Q: What the relation between weight and lead angle?

    Lead angle is the angle between the top and bottom weights.
    More lead angle increases forward speed.
    More top weight increases forward speed.

    90 degrees is the standard lead angle.

    75 degree gives maximum tumbling.
    120 degrees gives maximum forward movement.

    Top weight enhances separation.
    Bottom weight increases tumbling.
    Decreasing weight means to add weight on the other side.
    More load in the vibrator demand more weights.
    The less the total weight the better.
    Motor weight bottom is twice as the top
    If the vibrator jumps up and down means too many weights on the motor.

  • Q: What does “amplitude” and “lead angle” mean on a vibratory machine?

    Lead angle is the angle between top weight and bottom weight. In a vibratory finisher bowl “lead angle” means how aggressively the machine forward movement is. 90 degree is the standard lead angle.

    “Amplitude” means how strong the vibration movement is. Usually, we can measure with a vibration amplitude sticker.

  • Q: How often should I grease lubricate my vibratory machine?

    Grease your motor once a month if you run 8 hours a day. 1 shot of grease is enough. We recommend (Mobil XHP 222 or SHC 100).

  • Q: What the life time of your PU lining?

    We use Dow Chemical PU material to make the PU lining. PU lifetime 3-5 years depending on the user condition. Some user operates 16 hours a day with aggressive ceramic media may have a shorter lifetime.

    In case PU is damaged in a small area by parts, use Epoxy to recover the hole or scratches.

  • Q: What can I do with my waste water?

    The wastewater from mass finishing process firstly needs to remove solid substance above 0.5-2 um size. Most wear debris from ceramic media and plastic media can be removed, metal uses can also collect in the filter system.

    At Inovatec, we use pressure filter system to collect solid sludge. Sediment tank and centrifuge are also popular for the same purpose.

    The filtered water then neutralized and send to municipal waste water treatment plant for further processing.
