General Machinery Maintenance

In this guide, we’ll explore practical steps to prolong the life of your machines to category‑specific maintenance for various different types of machines you may have in your workshop.

Keep machines clean

Dust build-up is one of the biggest causes of machinery issues. After each session:

  • Brush away sawdust
  • Clear extraction ports
  • Vacuum inside cabinet bases
  • Clean tables and fences

Dust impacts precision, airflow, and safety - make cleaning a habit.

Lubricate moving parts

Friction wears out bearings, threads, slides, and gears.
Use:

  • Dry lubricant for threads
  • Machine oil for bearings and pivot points
  • Paste wax for cast iron surfaces

Protect cast iron from rust

Humidity causes corrosion. Keep surfaces protected using:

  • Machine wax
  • Camellia oil mist
  • WD‑40 Specialist anti‑corrosion spray

Avoid silicone-based polishes - they can contaminate wood finishes.

Check alignment and accuracy

Machines shift over time through vibration, temperature changes, or heavy use. Regularly check:

  • Table flatness
  • Fence alignment
  • Blade or cutter parallelism
  • Mitre gauge accuracy
  • Belt tension

Maintain sharp cutting tools

  • Blades, cutters, and knives need to be sharp for safe, clean operation
  • Dull cutters strain motors and increase burning or tear-out

Follow manufacturer service intervals

  • Always refer to your specific machine manual
  • Replace consumables (belts, bearings, filters) as recommended

Machinery Maintenance Tips

Below is a full set of category-specific maintenance guidance to help you prolong the life of your woodworking machines.

Bench Grinders, Polishers and Linishers

Keeping abrasive machinery in peak condition ensures smoother sharpening, better metal finishing and safer operation. These machines generate heat, dust and vibration, so regular checks are essential.

Cleaning and dust control
  • Brush away metal filings and abrasive dust after use
  • Clean guards, tool rests and housings
  • Check spark guards for clogging
Wheels and belts
  • Grinders: Dress wheels regularly to maintain flat, clean surfaces
  • Polishers: Replace worn mops and reapply compound
  • Linishers: Check belts for wear, glazing or tracking issues
Alignment and adjustments
  • Keep tool rests square and properly spaced from wheels
  • Ensure linisher belts track correctly using the tension/tracking knobs
  • Tighten all bolts and guards to reduce vibration
Safety checks
  • Inspect wheel condition: cracks, chips or glazing
  • Spin wheels by hand before turning on
  • Check emergency stop functionality

Drills, Mills and Morticers

Precision drilling and cutting machinery needs accurate alignment and clean mechanical movement to perform at its best.

Cleaning and lubrication
  • Remove chips and dust from tables, columns and bases
  • Lightly oil quills, slides and dovetail ways
  • Keep chuck tapers clean and lightly oiled
Belts and power transmission
  • Inspect belts for cracks or glazing
  • Correct belt tension to avoid slipping
Accuracy checks
  • Square tables to the bit
  • Check runout in drill chucks
  • Align morticer chisels and augers for clean mortices
Cutting tool care
  • Sharpen mortice chisels
  • Clean and replace dull drill bits or milling cutters

Dust Extractors

A well-maintained extractor protects both your machines and your lungs.

Filters and bags
  • Replace or clean filters as recommended
  • Empty bags/containers before they reach 75% capacity
  • Inspect HEPA or fine filters for clogging
Hoses and fittings
  • Check for leaks or collapsed hose sections
  • Clear blockages in bends and fittings
Motor and impeller
  • Inspect for excessive heat or vibration
  • Clean impeller blades if accessible
  • Check carbon brushes (if applicable)
Airflow efficiency
  • Avoid long ducting runs
  • Seal unused ports
  • Keep blast gates clean and fully functioning

Lathes

Lathes require smooth, aligned components for vibration-free turning.

Bed and ways
  • Clean ways after each use
  • Wax cast iron beds for corrosion resistance
Headstock and spindle
  • Check spindle bearings for noise or play
  • Keep collets and tapers clean
Tailstock
  • Clean and lightly oil the quill
  • Ensure alignment with headstock
Tool rests and banjo
  • Keep the top of rests smooth
  • Check locking mechanisms for wear
Chucks and accessories
  • Disassemble and clean scroll chucks
  • Lightly lubricate moving parts

Planers and Thicknessers

These machines depend on sharp blades, stable feeds and precise table alignment.

Cutters
  • Rotate or replace spiral insert cutters
  • Sharpen or replace straight knives
  • Clean resin build-up from blocks
Tables and beds
  • Wax planer beds for smooth feed
  • Clean infeed/outfeed tables
Feed system
  • Check rollers for wear or glazing
  • Clean rubber rollers with suitable cleaner
  • Adjust pressure settings
Alignment
  • Ensure tables are co-planar
  • Check thicknessing scale accuracy

Powerfeeds

Powerfeeds improve consistency and safety - but only when maintained properly.

Rollers
  • Inspect for wear, glazing or cracking
  • Clean resin and dust build-up
Arm and mountings
  • Tighten locking levers
  • Check arm swing and vertical movement
Gears and electronics
  • Inspect gearboxes for lubrication
  • Check speeds and feed consistency
Alignment
  • Ensure rollers are parallel to the workpiece
  • Adjust pressure height according to material thickness

Sanders

From belt sanders to drum sanders, proper care ensures accuracy and clean abrasion.

Abrasive components
  • Check belts/discs/drums for wear
  • Clean abrasives with rubber cleaning blocks
Tracking and tension
  • Adjust belt tracking
  • Maintain correct tension on belt machines
Dust control
  • Clean ports and internal dust build-up
  • Ensure extraction is adequate - sanding creates fine dust
Tables and guides
  • Keep tables square
  • Lubricate sliding mechanisms

Saws

Includes table saws, bandsaws, mitre saws, panel saws, etc.

Blades
  • Clean pitch and resin
