Key Features & Benefits

The CD120Q and CD230 automatic centrifugal disc finishing machines are production-scale systems. The defining difference from the manual CD series and the smaller automatic CD120B/CD230B models is the combination of higher capacity, double-bowl configuration options, and a complete automation package — hydraulic discharge, loading hopper, dosing pump and optional dryer — designed for high-volume continuous or semi-continuous production.

⚡

Up to 30× Faster Than Vibratory — High-Volume Automation

The CD120Q (120 L, 4 kW, 640 mm chamber) and CD230 (230 L, 7.5 kW, 800 mm chamber) deliver centrifugal disc finishing at speeds up to 30× faster than conventional vibratory bowl machines. This speed advantage compounds with automation: the loading hopper feeds parts into the bowl, the hydraulic discharge system unloads parts and media at cycle end, and the integrated separation sieve separates parts from media automatically. The double-bowl configuration (CD120Q×2, CD230×2) doubles throughput with two machines sharing one control system — the most common configuration for high-volume production lines.

  • Up to 30× faster than vibratory bowl — cycle times in minutes rather than hours
  • Hydraulic automatic discharge + loading hopper — minimal operator involvement per cycle
  • Double-bowl configuration available — doubles throughput with shared control system
⚡

26–30 mm Dow Chemicals PU Lining, VFD Speed Control

The CD120Q uses a 26 mm PU lining; the CD230 uses 30 mm. Both use Dow Chemicals (USA) raw material — the same specification as the Inovatec vibratory machine range. Thicker lining on the larger model reflects the higher impact energy at 800 mm diameter. Speed is controlled via a Bosch Rexroth variable frequency drive (VFD) across the full 0–180 rpm range for the CD120Q and 0–160 rpm for the CD230. Saved recipes allow operators to switch between part types by program number without manual parameter re-entry.

  • 26–30 mm Dow Chemicals PU lining — matched to chamber diameter and energy level for long service life
  • Bosch Rexroth VFD — stepless speed from 0–180 rpm; saved recipes per part type
  • Water discharge system built in — bowl drains and rinses automatically at cycle end
⚡

Compound Dosing + Optional Dryer Integration

The CD120Q and CD230 include compound dosing and water metering as standard — a ProMinent dosing pump delivers precise compound volume each cycle for consistent wet finishing. An optional vibratory dryer or conveyor belt dryer can be integrated immediately after the separation sieve, creating a complete finishing line: load parts → centrifugal disc finish → automatic separation → dry → collect. This eliminates all manual handling between finishing and the next production stage.

  • ProMinent dosing pump standard — precise compound and water metering for repeatable wet finishing
  • Optional vibratory dryer or conveyor belt dryer — complete load-to-dry automation in one line
  • Parts up to ~150 mm, thickness ≥1 mm — check part size against chamber diameter before ordering

CD120Q / CD230 Automatic Centrifugal Disc Finishing Machine — Product Overview

The CD120Q and CD230 are the production-scale automatic centrifugal disc finishing machines — a step up in capacity, automation and throughput from the smaller CD120B and CD230B models. The key differences are the larger chamber size (640 mm and 800 mm respectively vs the CD120B’s 640 mm standard configuration), the hydraulic automatic discharge system, the loading hopper for automated part feeding, and the availability of double-bowl configurations (CD120Q×2, CD230×2) for doubled throughput.

These machines are designed for manufacturers who are already using centrifugal disc finishing and need to scale production, or who are replacing multiple smaller machines with one larger automated system. The 120 L and 230 L capacities cover most small-to-medium part applications — stampings, castings, machined components, coin blanks, chain links, washers — with part size up to approximately 150 mm and part thickness ≥1 mm.

Inovatec’s Automatic Centrifugal Disc Finishing Machines deliver significantly shorter cycle times than traditional vibratory tumblers, helping reduce finishing costs while achieving a higher-quality surface finish. Centrifugal disc systems can process parts up to 30× faster than bowl-type vibratory equipment and offer enhanced automation compared with centrifugal barrel machines.

Frequently Asked Questions

Find answers to common questions about our products.

What is an automatic centrifugal disc finishing machine, and how is it different from a manual one?

+

An automatic centrifugal disc finishing machine adds automation features that reduce or eliminate manual steps in the finishing process. Compared with manual models, automatic systems typically include:

  • Automatic compound dosing (for wet processing)

  • Media/workpiece separation

  • Automatic timer and speed control

  • Automated draining and cleaning functions

  • PLC or touchscreen control panel

These machines are ideal for high-volume or multi-shift production, where reducing labor, improving consistency, and maximizing uptime are critical.

What types of automation features are available?

+

Typical automation features on modern centrifugal disc finishing machines include:

  • Automatic compound dosing
    A dosing pump (e.g., ProMinent) delivers water and finishing compounds accurately by time or volume for stable, repeatable wet processing.

  • Automatic media/part separation
    After the cycle, the bowl rotates or tilts to transfer the load to a separation screen. Media is returned to the work bowl, while finished parts are collected.

  • Speed and timer automation
    A frequency inverter (e.g., Bosch Rexroth) controls RPM and cycle time, allowing real-time adjustments for different media and part geometries.

  • Preset recipes / programs
    Operators can save and recall finishing programs by part type, reducing setup time and eliminating guesswork.

  • Optional automated loading/unloading
    Systems can be integrated with auto-lifters, conveyors, or robotic arms to support continuous, high-volume production.

What industries benefit most from automatic centrifugal disc machines?

+

Industries that benefit most from automated centrifugal disc finishing include:

  • Jewelry & watchmaking – high-value, delicate components requiring precise polishing

  • Electronics & connectors – small parts needing consistent edge rounding and deburring

  • Aerospace & automotive – medium-to-high volumes with strict surface-finish specifications

  • 3D printed / additive manufacturing – efficient batch post-processing and surface smoothing

  • Medical device manufacturing – stainless and titanium parts requiring burr-free, clean, and repeatable finishes

Automation improves repeatability, quality control, and process compliance, especially across multiple shifts and operators.

What maintenance is required for automatic systems?

+

Even with automation, routine checks are essential to keep performance consistent and prevent unplanned downtime:

  • Dosing pump: Inspect filters, verify compound viscosity, and clean the system monthly.

  • Control panel: Keep firmware up to date and confirm emergency stops function correctly.

  • Separation unit: Clean screens regularly to prevent clogging and cross-contamination.

  • Disc drive system: Grease bearings and inspect motor couplings monthly.

  • PU lining wear: Check for delamination or excessive wear every 6–12 months.

A preventive maintenance routine ensures long-term reliability—especially in continuous or multi-shift operation.

Can the machine be integrated into a smart factory or ERP system?

+

  • Yes. Many advanced automatic centrifugal disc finishing machines can be integrated with PLC + IoT + remote interfaces, enabling:

    • Real-time monitoring of cycle status, temperature, water flow, and compound consumption

    • Remote diagnostics and parameter control via Ethernet or Wi-Fi

    • ERP/MES connectivity to link finishing data with production scheduling and QA documentation

    • Smart alarms for low compound levels, overheating, overload, or abnormal operating conditions

This makes it a great fit for Industry 4.0 applications, especially in precision manufacturing environments.

What is the difference between the CD120Q and CD120B, and between CD230 and CD230B?

+

The CD120Q and CD230 (this page) are the larger-footprint, higher-automation models with hydraulic discharge, loading hopper, and double-bowl configuration options. They are designed for high-volume production lines where throughput and automation level are the primary requirements.

The CD120B and CD230B are more compact automatic models with the same bowl capacity but a smaller overall machine footprint and standard (non-hydraulic) discharge. They are better suited for mid-volume production where floor space is limited and the double-bowl configuration is not required.

All four models use the same centrifugal disc finishing mechanism and achieve the same surface quality for the same part types. The selection is driven by: required throughput per shift (double-bowl CD120Q×2 or CD230×2 for highest volume); floor space available; level of automation integration with upstream and downstream equipment.
