Manufacturing Maintenance

 What auditors look at on the floor   ISO 9001:2015 treats the environment your processes run in as something you must determine and manage, cleanliness included. In a machine shop that means oil under a lathe, swarf in an aisle, water tracked in from the dock. Inspectors turn it into plain questions: how often, who checks, where is it written down. That is ISO 9001 floor cleaning in practice.   What 5S adds. 5S gives you a vocabulary the auditor already knows. Shine is the cleaning step, but Standardize and Sustain are the ones that get tested, because they are about a written standard followed by somebody other than its author. On 5S factory floors, that usually shows up as a board in the aisle with the week's sign-off on it.   Zone map: production, warehouse, walkways, loading   One program for the entire site is why cleaning plans fall apart at audit. Soil, traffic and risk differ by zone, so the task list has to differ too. Draw it on a print of your layout and give each zone an owner.   Production. Coolant mist, hydraulic oil, metal fines, plastic dust. The hard part is the perimeter: the machine base, the cable tray shadow, the space behind the chip conveyor. Cleaning here has to reach the edge without pushing fines into a drain.   Warehouse. Tyre marks, pallet dust, and the polished patch where a forklift brakes at the end of a run. Aisles are long and open, which is where wide ride-on machines earn their keep, provided they can turn at the end without a shuffle.   Walkways. Foot traffic, handover points and door entries. This is what a visiting customer sees first, and it is usually the zone with no owner. Marked lanes make the standard visible and give you a boundary to point at.   Loading. Grit, diesel soot, rainwater, the odd broken pallet. The dock door line is where the outside arrives. A mat and a sweep routine there cuts the soil load on every zone inside, and it is the cheapest decision on this list.   Cleaning without stopping production Production will not pause for the floor, so the program has to fit the gaps that exist: changeovers, breaks, shift handover and the hours after last shift. Battery machines help here for a reason that has nothing to do with power. No mains cable means no trip hazard strung across a walkway, which is a finding on its own, and no lead to drag around a running line.   Work the site in slices. Clean one aisle at a time, dry it before traffic returns, and plan the route around the turning circle rather than straight-line speed. A route needing three-point turns in a two-metre aisle takes twice as long as the spec suggests.   Drying time decides whether the task survives. A squeegee in good condition and sensible brush pressure leave a floor that takes foot traffic in minutes. If the floor is still wet when the next shift walks in, the task gets dropped within a fortnight, whatever the sheet says.   From the field: what actually decides the machine Jiechi has built scrubbers and sweepers since 2003 across two bases totalling 60,000 m². When a plant layout lands with us, the useful questions are almost never about total area. They are about where soil collects, which aisles take traffic, and when the floor is free of people and pallets. Those three answers set the machine class and the pass pattern. We size to the window you have, not to the number on a brochure. Machine choice by zone Buy to the zone, not to the biggest area on the plan. One large machine for everything ends up too wide for the production aisle and too slow to turn in the warehouse. Zone Machine class What to look for Production Ride-on scrubber, dual brush 850 to 1,000 mm scrub width, tight turn radius, low noise for changeover work Warehouse Ride-on scrubber or combination unit Long run time, tanks over 200 L, good transport speed Walkways Compact walk-behind Under 800 mm, useful edge cleaning, quiet enough for daytime Loading Sweeper-scrubber combination Debris hopper, suction path over 1.2 m, dust control on dry days   For the two biggest zones, an industrial ride-on scrubber with dual brush carries the middle of the plant: 860 mm on the A8 and 1,015 mm on the A10, with 280 L of solution and 300 L of recovery on a 36V/220Ah pack, rated at 6,500 and 7,000 m²/h. Two brush motors give the pressure to lift cured coolant film a single brush skates over.   Where the floor is half outside, grit has to be swept before it can be washed. The large ride-on sweeper-scrubber M17 does both in one pass, rated at 8,600 m²/h with a 1,400 mm suction path, 300 L solution and 350 L recovery on 36V/460Ah. It is the machine for the dock approach, not the aisle beside line three.   Whatever you shortlist, ask for the demonstration on your floor, in your narrowest aisle, at the hour you would really clean. A machine that only performs in an empty warehouse will not last a month.   FAQ How often should a factory floor be machine scrubbed? Daily in production aisles and walkways, weekly in loading bays, plus a deep clean at each planned shutdown. Set it by how fast soil returns. What records does an audit expect for floor cleaning? Enough to follow one date backwards: task, zone, frequency, who signed it and what was used. Photos from fixed viewpoints once a week are usually enough. Who should own the cleaning program? One named person per zone, not a department. Where cleaning belongs to everybody, nothing gets signed. Can we clean while the line is running? Yes, in slices. Battery machines remove the cable hazard, a good squeegee returns the floor to traffic in minutes, and the route should avoid the busiest aisle at peak times.
