Blade clamp in 320 mm for planer thicknesser Holzmann HOB320P and Holzprofi ADM320 - Sold individually without screws
M6x11 screw for blade clamp on Holzmann HOB320P and Holzprofi ADM320
This category is dedicated to spare parts for the Holzprofi ADM320 planer thicknesser, a 320 mm woodworking machine designed for surface planing and thicknessing. Its cast-iron tables and robust mechanical construction are supported by drive, adjustment, cutting and safety components that can require maintenance or replacement over the life of the machine.
Part availability changes with sourcing and production. This page is therefore not a fixed inventory of what happens to be in stock today. It is intended as a long-term resource for maintaining, repairing and restoring a Holzprofi ADM320, while taking the exact production version into account.
The cutterhead is one of the key assemblies of the ADM320. This model has notably been supplied with a conventional cutterhead using planer knives. Knives, clamping bars or wedges, locking screws and related fixing components must remain in good condition to hold the cutting tools securely during operation.
When replacing knives or servicing the cutterhead, inspect the clamping surfaces and screws. Distortion, damaged threads or uneven clamping can prevent correct knife positioning and affect surface finish. Always verify dimensions and references before ordering; visual similarity alone is not sufficient to establish compatibility.
Power is transmitted from the motor to the cutterhead and associated mechanisms through mechanical drive components. Depending on the ADM320 version, servicing may involve a drive belt, pulley, bearing or another transmission part. Some individual references can be shared with machines of similar design, but compatibility must be confirmed for each specific component.
If a belt slips, wears rapidly or runs out of alignment, do not replace it without checking the surrounding drive. Inspect pulley condition and alignment, bearing rotation and belt tension. Noise or vibration can originate from a bearing or another transmission component rather than from the belt itself.
During thicknessing, timber must feed consistently beneath the cutterhead. Feed rollers and the mechanisms that drive them are therefore subject to repeated loads. Wear, contamination, transmission faults or incorrect adjustment can lead to jerky feeding, insufficient traction or irregular marks on the workpiece.
Before replacing a feed component, inspect neighbouring parts and remove accumulated chips. A feeding problem may originate from the drive, roller, spring, bearing or adjustment mechanism depending on the machine configuration. Diagnosis should start with the actual symptoms rather than an assumed failed part.
The ADM320 uses ground cast-iron tables designed to change between surface-planing and thicknessing operations. Its tilting surfacing fence must remain stable when preparing a reference edge. Hinges, shafts, handles, locking mechanisms, brackets and other adjustment parts can loosen, wear or become damaged over time.
If a table becomes difficult to move, the fence develops play or an adjustment no longer locks securely, inspect the complete mechanism. Check accessible fasteners, shafts, threads and bearing surfaces before replacing only the visible handle or control.
Thicknessing requires accurate table-height adjustment to obtain the required finished dimension. The handwheel, screw mechanism, raising and lowering system, height indicator and guides may all contribute to this adjustment depending on the ADM320 version. Wear or play can make adjustment difficult or reduce repeatability.
The ADM320 also contains electrical components required for operation and safety. Depending on the version, fault finding may involve the supply, motor, switch, contactor, safety device or connection component. A machine that will not start does not automatically have a failed motor.
For any electrical replacement, record the original markings, voltage, terminal arrangement and reference where readable. Never select a switch or contactor simply because its casing looks similar. Disconnect the machine before inspection, and work requiring electrical expertise should be carried out by a competent person.
IMPORTANT: BEFORE PURCHASING, carefully check the list of compatible machines shown on each product page.
For some spare parts, the model name alone is not enough to guarantee compatibility. Production changes can mean that Holzprofi ADM320 machines from different periods use different components.
If you are unsure, send us the exact model, month and year of manufacture and serial number before ordering. Clear photographs, dimensions and any markings on the original component are also useful.
Some ADM320 components may be explicitly listed as compatible with other machines of similar design, including certain Holzmann models. This can help keep an older machine in service, but compatibility must never be assumed across the complete machine. A shared belt, screw or knife-clamping component does not mean that motors, bearings, electrical controls or other parts are interchangeable.
Use the compatibility information on the individual product page and compare the original component dimensions. Depending on the part, useful measurements include length, diameter, bore, thread and tooth Probois Machinoutils – SEO pièces Holzprofi ADM320 Page 5 count.
An exploded parts diagram is extremely useful when identifying a replacement component. Locate the part on the drawing and record its item number. This makes reference checking easier and reduces confusion between visually similar parts. Make sure the documentation corresponds to the production version of your ADM320.
If the required component is not displayed online, send a photograph of the rating plate, an overall view of the affected assembly and several clear photographs of the removed part. This information is often essential when investigating a reference that has not yet been published in the category.
Routine maintenance helps preserve accuracy and reduce breakdowns. With the machine disconnected, inspect accessible transmissions, fasteners and adjustment mechanisms and remove accumulated chips. Effective extraction limits waste around the cutterhead, feed system and moving parts.
Probois Machinoutils develops an evolving range of Holzprofi ADM320 spare parts. References can be added or become unavailable as sourcing changes. Accurate machine and component identification therefore remains the best basis for a durable repair and for extending the service life of an otherwise sound ADM320.
