To determine the knife height for a spindleless veneer peeler machine, you can follow these steps:
Understand the machine specifications: Refer to the machine’s operating manual or consult the manufacturer to familiarize yourself with the specific guidelines and recommendations for determining the knife height. Different models of spindleless veneer peeler machine may have varying requirements.

Consider the veneer thickness:
Determine the desired thickness of the veneer sheets you want to produce. This will help you determine the appropriate knife height. For thicker veneer sheets, a higher knife height may be required, while thinner sheets may necessitate a lower knife height.
Test and adjust:
Conduct test runs with different knife height settings to evaluate the quality of the peeled veneer and make necessary adjustments. Start with a conservative knife height and gradually increase or decrease it based on the desired veneer thickness and the performance of the machine.
Evaluate the veneer quality:
Assess the quality of the peeled veneer sheets produced at different knife heights. Look for factors such as uniform thickness, smooth surface, minimal tear-out or defects, and overall consistency. Choose the knife height that yields the best results in terms of the desired veneer quality.

Consider the log characteristics:
Take into account the characteristics of the logs being used for peeling. Different log diameters, wood species, and moisture content can impact the optimal knife height. Adjust the knife height accordingly to accommodate the specific log characteristics.
Seek expert advice if needed:
If you encounter challenges or uncertainties in determining the knife height, it is advisable to consult with experts or experienced operators of spindleless veneer peeling machines. They can provide valuable insights and guidance based on their knowledge and practical experience.
Remember to always prioritize safety when adjusting the knife height. Follow proper safety procedures and guidelines provided by the machine manufacturer to avoid any accidents or injuries during the adjustment process.
