Spare parts for the Holzmann PB80N band saw blade sharpener

This category is dedicated to spare parts for the Holzmann PB80N band saw blade sharpener. The PB80N is a semi-automatic sharpening machine designed to resharpen the teeth of band saw blades used in woodworking shops, sawmills and similar applications. It uses two separate motors, one driving the grinding wheel and the other operating the blade feed mechanism.

No spare parts are currently listed in this category. It is intended to be expanded progressively as components for this machine are identified and made available. The information here therefore helps owners understand the PB80N, prepare a spare-part enquiry and collect the details needed to avoid compatibility errors.

A semi-automatic sharpener for band saw blades

The Holzmann PB80N accepts blades from 2000 to 5000 mm long, 15 to 50 mm wide and up to 2 mm thick. It is designed for tooth spacing from 8 to 30 mm. In automatic operation, the feed system can process up to 70 teeth per minute.

The machine uses a 250 W grinding motor and an 80 W feed motor on a 230 V / 50 Hz supply. Grinding-wheel inclination is adjustable from 0 to 40 degrees. These specifications explain why troubleshooting should distinguish between the grinding system, blade-feed mechanism, mechanical adjustments and electrical supply.

Which PB80N components may require inspection?

Like any sharpening machine, the PB80N contains assemblies exposed to work, vibration and wear: grinding-wheel motor, feed motor, blade-feed mechanism, adjustment devices, blade supports and electrical components. The grinding wheel is also an essential consumable in the sharpening process.

These assemblies are mentioned because they are documented parts of the PB80N design, not because every one is already offered for sale in this category. When a spare part is listed, its product page will state its function and compatibility. Until then, the exploded parts drawing and machine identification details remain the best basis for a precise enquiry.

Diagnose poor sharpening before replacing a part

Uneven tooth sharpening does not necessarily mean that a component is broken. First check machine settings, blade positioning, grinding depth and feed consistency. Incorrect blade positioning or a setting that does not match the tooth pitch can change the sharpening result considerably.

Also inspect the grinding wheel. A worn, loaded or unsuitable wheel can reduce sharpening quality. The current PB80N specification uses a wheel measuring Ø175 x 8.4 x Ø32 mm. Before replacing a mechanical or electrical component, confirm that the consumable and settings are suitable for the blade being sharpened.

Checking the blade-feed system

Semi-automatic operation relies on a motorised feed system that presents each tooth to the grinding wheel in sequence. If feeding becomes irregular, the blade stops advancing correctly or tooth spacing is no longer followed consistently, several checks should be made before concluding that the feed motor has failed.

Make sure the blade moves freely on its supports, that nothing obstructs its travel and that feed adjustments are correctly set. Look for abnormal play, loose fasteners or mechanical resistance. Any work on the mechanism must be carried out with the machine stopped and disconnected from the mains.

Checking the motors and electrical system

If the grinding wheel no longer starts or the feed system remains stationary, identify which motor and function are affected before ordering anything. The PB80N has two motors with different duties: 250 W for grinding and 80 W for feed. Photograph the identification markings on the relevant component and visually inspect accessible connections.

An electrical fault should never be diagnosed from one symptom alone. A supply problem, control fault, loose connection or mechanical blockage may prevent a motor from operating correctly. Internal electrical testing should be performed only by a person with appropriate electrical knowledge.

Preventive maintenance of the Holzmann PB80N

Grinding dust and metal particles should be removed regularly from accessible areas. Keep the sharpening station, blade supports and adjustment mechanisms clean. Periodically inspect fasteners and watch for vibration, unusual noise or play that could affect sharpening accuracy.

A correctly adjusted and maintained machine reduces unnecessary loads on the grinding wheel, feed mechanism and motors. Before each use, make sure the blade is properly supported and guided. After maintenance or repair, carry out a progressive test while observing blade travel and the way each tooth passes the wheel.

How to identify the correct PB80N spare part

For a Holzmann PB80N spare-part enquiry, the model name is only the first identification step. Record the information on the machine identification plate, including model, manufacturing date and serial number where available.

Then consult the PB80N manual and exploded parts drawing to identify the component position. Photograph the part before removal, including its mounting points, connections and all visible references. Measure relevant dimensions if no reference is readable. This information greatly improves the accuracy of a manufacturer spare-part search.

Is the part you need not yet listed?

Because this is a new category, no PB80N spare parts are currently published here. If you already need a component, send us the position number from the exploded drawing, a photograph of the machine identification plate and clear photographs of the part. Also describe the fault or symptom to help with identification.

This approach is safer than searching by appearance alone. Two visually similar components may have different dimensions, connections or specifications. The information allows the reference to be checked before a product is added or offered.

IMPORTANT: check compatibility before ordering

IMPORTANT: BEFORE PURCHASING, carefully check the list of compatible machines shown on each product page.

For some spare parts, the machine model alone is not sufficient to guarantee compatibility. Manufacturer changes can mean that the same model was fitted with different components during its production life.

If you are unsure, please provide the exact model, month and year of manufacture, and serial number of your machine before ordering.

Probois Machinoutils and Holzmann PB80N spare parts

Probois Machinoutils is progressively developing its range of replacement parts for Holzmann machines. This category is intended to bring together parts for the PB80N band saw blade sharpener as references are identified and become available.

Our aim is to help you maintain, diagnose and repair your Holzmann PB80N sharpener whenever technically possible. Accurate identification of the component and machine version supports repair rather than unnecessary machine replacement and helps extend equipment service life.
