Gear hobbing and thread rolling oil smoke extraction
Gear hobbers and thread rolling machines flood the cut with neat oil, and the cut throws fine oil smoke into the shop air on every part. Share your machines, oil and layout so extraction can be matched to the duty.
Fine oil smoke on every part, all shift
Gear hobbing cuts teeth at speed with the hob and blank flooded in neat cutting oil, and thread rolling forms threads under high pressure with oil as the lubricant. Both atomise the oil at the point of work, and the finest fraction stays airborne as smoke. Gear shops and fastener shops run these machines in long cycles, so the haze builds and settles as an oily film on machines, floors and finished parts unless it is captured at the source.
A straight-oil smoke duty
Listed ESP application
The Cleanmist ESP series brochure lists hobbing and thread rolling under its straight-oil machining applications, with broaching, deep-hole drilling and cold heading. Electrostatic cells capture the sub-micron oil particles and drain the recovered oil.
Not a coolant-mist duty
Hobbing and thread rolling run neat oil, not water-mix coolant, so this is a smoke duty rather than the mist duty the CM series covers. Confirm the oil before choosing.
Open and enclosed machines
Older hobbers and thread rollers run open; newer machines carry enclosures. Smoke escapes at openings and at every door-open between parts, so capture belongs at the cutting zone or connected to the enclosure.
Continuous duty
Hobbing cycles run minutes per part and machines work long shifts. Extraction has to keep up with continuous emission, not an occasional burst.
Choosing the extraction arrangement
The ESP series covers ESP1000 (rated 1000-1500 CMH, 250 W), ESP2000 (2000 CMH, 430 W) and ESP4000 (4000 CMH, 770 W), on a 220-240 V single-phase supply with 99% filtration efficiency. These are collector ratings from the brochure, not confirmed airflow requirements for any specific hobber or thread roller.
At the cutting zone
A pickup arranged over the hob and blank or connected to the machine enclosure captures smoke where it forms. Send photos of the cutting zone, covers and the space above the machine.
Per-machine or shared
One ESP per machine suits machines on different cycles. A row of hobbers on similar duty can share a ducted arrangement when airflow is planned for the combined load.
Washable cells
ESP collecting cells are washed and reused; the standard configuration uses no disposable filter media. A washable metal-mesh pre-filter catches larger droplets, and the optional HEPA after-filter is a separate replaceable element.
Recovered oil
Electrostatic collection drains the captured oil for handling per your shop's practice, instead of loading it into throwaway media.
What to send us before choosing
Machine list
Hobber, gear shaper or thread roller make and model, and whether each machine is open or enclosed. Note any existing extraction.
Cutting oil
The oil product name; the safety data sheet helps confirm the duty.
Working pattern
Parts per hour or shift, hours per day, and how often doors or covers open between cycles and setups.
Layout
Photos of the cutting zones and the space above and beside each machine, machine spacing, and any ducting routes.
Common questions about hobbing and thread rolling smoke extraction
Does the ESP series cover hobbing and thread rolling oil smoke?
Yes. The ESP series brochure's straight-oil machining application lists hobbing and thread rolling alongside broaching, deep-hole drilling and cold heading - processes where neat oil becomes airborne. Electrostatic cells capture the fine oil particles and drain the recovered oil.
Are the ESP collecting cells washable?
Yes. The ESP cells are washed and reused; the standard configuration uses no disposable filter media. An optional HEPA after-filter is a separate replaceable element.
Can one ESP serve more than one machine?
It can when ducting and airflow are planned for the combined duty. Share the machine models, their positions and their working pattern and the arrangement can be checked.
Our machines are enclosed. Is extraction still needed?
An enclosure slows the spread but smoke still escapes at openings and when doors open between cycles and setups. Extraction connected to the enclosure or arranged at the cutting zone captures smoke before it reaches the shop air; send photos of the openings and guarding.
What should I send first for a hobbing or thread rolling application?
Your machine make and model (hobber, gear shaper or thread roller type), the cutting oil product name, parts per hour or shift, photos of the cutting zone and the space above it, and how many hours per day the machines run.
