The ZHM series economic vibratory tumbler uses the same operating principle as the higher-end VBS and VB series machines — vibration-driven toroidal media flow for deburring, edge rounding and surface smoothing — at a lower initial cost by using a simpler motor and control system. The three design elements below explain the practical differences from the full VBS/VB range.
The ZHM series uses a direct-drive vibration motor running at a fixed 1450 rpm — simpler and more reliable than the VFD-controlled motors in higher-end models. Without a variable frequency drive, the amplitude range is narrower (0.8–6 mm depending on model), set by adjusting the imbalance weights rather than motor speed. For small factories processing standard metal and plastic parts with consistent part geometry, this is sufficient. The motor comes pre-mounted and tested; no commissioning is required.
The ZHM bowl is PU-lined throughout, with lining thickness ranging from 6 mm on the smaller models (ZHM-40A to ZHM-95A) to 20 mm on the larger models (ZHM-250A to ZHM-450AB). The lining protects the bowl from media abrasion and reduces transmitted noise. The lining is replaceable when worn — only the lining needs to be replaced, not the bowl body.

The ZHM economic vibratory tumbler is the entry-level model in the Inovatec vibratory finishing range. It uses the same bowl-vibration finishing principle as the full VBS and VB series machines, delivering effective deburring, edge rounding, surface smoothing and cleaning for standard metal and plastic parts. The difference from higher-end models is in the motor and control system: the ZHM uses a fixed-speed direct-drive motor instead of a VFD-controlled motor, which lowers cost and simplifies operation at the expense of amplitude adjustment flexibility.
For small factories processing parts with consistent geometry and standard deburring or pre-plating requirements, the ZHM provides reliable batch finishing results at lower capital cost. If your process requires precise amplitude control for different part materials, or continuous multi-shift production with heavy loads, the VBS(A) or VBS(B) series is more appropriate.

An Economic Vibratory Tumbler is a cost-effective mass finishing machine used to process parts in batches through vibration. It is commonly used for deburring, edge rounding, surface smoothing, cleaning, rust removal, and pre-polishing for small to medium-sized factories.
This model is ideal for small factories and workshops that need:
Stable batch finishing performance
Lower initial investment compared to high-end systems
Simple operation and quick operator training
Reliable day-to-day production for common metal and plastic parts
Typical parts include:
CNC machined parts (aluminum, stainless steel, carbon steel)
Stamping parts and sheet metal components
Die-cast parts (aluminum/zinc)
Hardware, fasteners, fittings
Small automotive / motorcycle components
Plastic parts (with proper media selection)
Depending on your parts and media selection, you can achieve:
Burr removal and edge rounding
Uniform matte/satin surface finishing
Surface smoothing before plating/powder coating/anodizing
Cleaning and rust removal
Pre-polishing (and in some cases polishing) results
Throughput depends on part size, material, burr level, media type, and cycle time.
As a general guideline for small factories:
Light deburring: higher throughput, shorter cycles
Smoothing / pre-polish: moderate throughput, medium cycles
To estimate your real throughput, we recommend sending part photos + material + burr description + daily target (kg/day) for a quick calculation.
A practical selection method for small factories:
Choose based on daily output target (kg/day) and part size + batch volume
Keep enough space for media circulation and consistent finishing
Quick selection guideline:
Small workshop / trial production: smaller bowl volume models
Stable small-batch production: mid-size bowl volume models
Higher daily output: larger bowl volume models or multiple machines
If you share your part dimensions + daily kg/day, we can recommend the most suitable model in 1–2 options.
Media selection is the key to results:
Ceramic media: strong cutting, good for deburring and smoothing metals
Plastic media: gentler cutting, good for aluminum/zinc and sensitive parts
Steel media: burnishing and brightening (typically with compound)
We can recommend media shape/size to avoid part-to-part damage and improve consistency.
Yes—most vibratory finishing processes perform better with compound:
Helps cleaning and prevents redeposition
Controls cutting rate and improves surface consistency
Reduces media/part staining and improves brightness
We can recommend compound type based on your material + target finish.
Cycle time varies widely:
Light deburring: typically shorter
Smoothing / pre-polish: medium
High finish requirement: longer
For accurate guidance, provide before-part photos, and we can suggest a realistic cycle-time range.
Proper setup prevents damage:
Correct media size prevents part lodging
Proper ratio of parts/media avoids collisions
Appropriate compound reduces surface marks
We will recommend an optimized process to protect parts and maintain stable results.
Yes. This economic model is designed for simple daily operation:
Straightforward controls
Easy loading/unloading routine
Practical maintenance steps
We also provide operating guidance and process recommendations for your parts.
Typical maintenance includes:
Regular cleaning of the bowl and discharge area
Checking fasteners, springs, and wear items
Monitoring the lining condition (PU lining longevity depends on usage)
With proper use, maintenance is simple and production-friendly.
Common upgrades for small factories include:
Variable Frequency Drive (VFD): adjust speed/amplitude for different parts
Dosing pump system: automatic compound dosing for stable finishing
Sound cover: reduce noise and improve workshop environment
Media separator / screen options: improve efficiency and reduce labor
Tell us your workflow and we will recommend the best configuration.
The ZHM economic model uses a fixed-speed direct-drive vibration motor at 1450 rpm. Amplitude is adjusted by changing the imbalance weight angle — a manual adjustment. This is reliable and sufficient for most standard deburring and polishing applications, but does not allow on-the-fly amplitude changes during a production run.
Higher-end VBS(A), VBS(B), VB(A) and VB(B) models use a variable frequency drive (VFD, Bosch Rexroth) that allows stepless amplitude adjustment from the control panel without stopping the machine. VFD control is valuable when you process different part materials in successive batches (soft aluminum vs hard steel require different amplitudes) or when you need soft start to extend motor life in continuous shift production.
Other practical differences: higher-end models use hot-poured Dow Chemicals PU lining (harder, longer-lasting) vs the ZHM’s cast PU; and higher-end models are built to higher cycle-duty ratings for continuous multi-shift production.
The ZHM is the right choice when: your parts are standard metal or plastic; your daily volume fits within a single or double shift; process requirements are consistent; and capital cost minimisation is the primary decision factor.
