A quality built industrial knife grinder should give you 20 years or so of good service. However, we at Colonial Saw have seen them last half that long if they are poorly maintain (or sometimes not maintained at all). In order to keep your knife grinder in a reliable and safe condition for a long time, the following maintenance schedule is recommended:
Maintenance Prior to Every Work Shift
- Check that safety guards and devices are present and functioning properly.
- Verify that the grinding wheel is intact, properly mounted and not vibrating. If the wheel is chipped, it must be replaced prior to use.
- Make sure the sliding guides of the carriage are clean and then lubricate with a couple drops of weigh oil.
- Lubricate all exposed metal parts, since these are more subject to oxidation.
Monthly Maintenance(Every 200 working hours)
- Check the electrical sheaths and cables for damage. If they are crushed, frayed or damaged, they should be replaced as the machine may have intermittent problems that will drive you nuts.
- Inspect the play between the grinding carriage and sliding guides. If necessary, adjust the rollers so that all 4 sides are touching equally and there is no lateral twist when the carriage changes direction.
- Assure the machine runs its full stroke both back and forth several times and the head travels up and down its full stroke several times (grease the head up/down mechanism at this time)…using the machine in the same range for long periods of time without running a full stroke can present problems.
- Tilt the chuck its full 0 to 180 degree motion. Fill the Chuck tilt’s grease fittings with grease.
- Six Month Maintenance (Every 1000 working hours)
- Inspect all the bolts to determine that they are tightened securely.
- Inspect the oil level in the carriage drive reduction gear.
- Check the chain tensioning.
- Grease the chain and the downfeed mechanism
