Keep bowl volume separate from part batch load
The 03/16 PDF lists CM 305 with 350 L gross and 195 L conditional usable volume; CM 405 has 420 L gross and 285 L conditional usable volume. The footnote ties the media-to-workpiece ratio to geometry, material and delicacy or nicking risk. Neither column supplies a universal part-only load, bulk density, daily output or cycle time. Record the actual part and media constraints before a representative sample trial.
Review the diagonal and separation interface
The listed diagonal limits are 220 mm for CM 305 and 250 mm for CM 405. A single diagonal value cannot prove motion clearance, nesting, lodging risk, contact damage or complete unloading. This brochure states that CM has no integrated separation device. Optional paddle-wheel dividers and a pneumatic unload gate are descriptions to review with the supplier, not proof that either offered machine has these options installed.
Keep drive rows tied to their version
CM 305 lists 2.6 kW at 1,500 rpm; CM 405 lists 2.6 kW. Their standard speed entries are 1,000/1,500 and 1,000/1,500. Two-speed alternatives are not a continuous recommended processing range. Inverter maxima are equipment limits, not a validated setpoint. Drive power is not measured energy consumption or total connected load, and no energy cost or productivity is calculated. Ball burnishing is a separate version: the power entries are 2.6 kW and 4.0 kW, and speed entries are Frequency inverter adjustable up to 1,800 rpm (joint first-five-model cell) and Frequency inverter adjustable up to 1,800 rpm (joint first-five-model cell). The shared first-five-model speed cell was verified visually in the PDF. A dash is missing printed data, not zero or proof that the version is unavailable. Force units are not printed in the CM PDF table and are not silently filled from the website.
Review accessories and supplier drawings
The catalog drier references are G 500 for CM 305 and G 500 for CM 405. These are brochure accessory references, not installation, compatibility, stock or quotation approval. Review discharge interface, part/media separation, drying suitability and material-specific acceptance with the responsible supplier. Lettered drawing dimensions are omitted from this tool; no floor plan or maintenance clearance is inferred.
Current official web table and version differences
CM 305: usable is 195 in the PDF and 190 under the current web label "Useful volume* (l)". CM 405: usable is 285 in the PDF and 260 under the current web label "Useful volume* (l)". CM 305: weight is 635 in the PDF and 545 under the current web label "Total weight (empty) (kg)". These are unresolved version differences. Keep the PDF reference separate and request the offered specification.

Questions about this model pair
How do CM 305 and CM 405 compare in bowl volume?
The 03/16 PDF lists CM 305 with 350 L gross and 195 L conditional usable volume; CM 405 has 420 L gross and 285 L conditional usable volume. The footnote ties the media-to-workpiece ratio to geometry, material and delicacy or nicking risk. Neither column supplies a universal part-only load, bulk density, daily output or cycle time. Record the actual part and media constraints before a representative sample trial.
Do their diagonal limits establish part fit?
The listed diagonal limits are 220 mm for CM 305 and 250 mm for CM 405. A single diagonal value cannot prove motion clearance, nesting, lodging risk, contact damage or complete unloading. This brochure states that CM has no integrated separation device. Optional paddle-wheel dividers and a pneumatic unload gate are descriptions to review with the supplier, not proof that either offered machine has these options installed.
Can their catalog speeds be used as process settings?
CM 305 lists 2.6 kW at 1,500 rpm; CM 405 lists 2.6 kW. Their standard speed entries are 1,000/1,500 and 1,000/1,500. Two-speed alternatives are not a continuous recommended processing range. Inverter maxima are equipment limits, not a validated setpoint. Drive power is not measured energy consumption or total connected load, and no energy cost or productivity is calculated.

Which accessory references require confirmation?
The catalog drier references are G 500 for CM 305 and G 500 for CM 405. These are brochure accessory references, not installation, compatibility, stock or quotation approval. Review discharge interface, part/media separation, drying suitability and material-specific acceptance with the responsible supplier. Lettered drawing dimensions are omitted from this tool; no floor plan or maintenance clearance is inferred.
Does the current official website agree with this PDF version?
CM 305: usable is 195 in the PDF and 190 under the current web label "Useful volume* (l)". CM 405: usable is 285 in the PDF and 260 under the current web label "Useful volume* (l)". CM 305: weight is 635 in the PDF and 545 under the current web label "Total weight (empty) (kg)". These are unresolved version differences.
