Spring-Loaded Ski Sidewall Machining for Precise Edge Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual chip-removing machining of ski side walls is time-consuming and dependent on user skill, often leading to incomplete preparation for edge grinding, which shortens the service life of grinding tools.
Innovation Solution
A machining apparatus with a support for the ski and a device using spring-loaded cutting tools on a tool carrier, guided transversely to the conveying direction, allows for precise and efficient removal of side walls, independent of ski width and edge profile, with optional simultaneous machining of both sides and a chip removal system using flushing fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual chip-removing machining of side walls is performed, then the steel edges can be exposed for grinding, but the machining quality depends on user skill and it is time-consuming
Solution Approach 1:
The cutting tool is spring-loaded to automatically apply cutting force to the side wall during ski conveyance. The resilient actuator self-regulates the cutting pressure, eliminating dependence on manual skill while maintaining consistent machining quality across different operators.
Solution Approach 2:
The manual mechanical operation is replaced by an automated spring-loaded cutting tool system. The resilient actuator provides automatic force application, substituting human manual labor with a self-regulating mechanical system that operates consistently during ski conveyance.
2Ease of manufacture
If manual side wall machining is performed, then some preparation can be done, but it requires separate manual operation before grinding
Solution Approach 1:
The side wall machining operation is merged with the ski conveyance and grinding process into a single automated sequence. The cutting tool operates automatically during conveyance, eliminating the need for separate manual preparation steps before grinding.
Solution Approach 2:
The cutting tool operates continuously during ski conveyance rather than requiring separate manual intervention. The spring-loaded tool maintains continuous cutting action as the ski moves through the apparatus, ensuring uninterrupted preparation of the side walls.
3Reliability
If more grinding cycles are used to compensate for incomplete side wall preparation, then grinding can still be performed, but the service life of grinding tools is shortened
Solution Approach 1:
The cutting tool performs preliminary removal of side wall material before the grinding process. By pre-exposing the steel edges through automated cutting during conveyance, the grinding tools can operate more efficiently with fewer cycles, extending their service life while maintaining reliable grinding capability.

AI summary
An apparatus for machining a ski includes a support for the ski and a device for conveying the ski in the longitudinal direction of the ski, along the support. The support is assigned a device for machining the side walls of the ski using at least one cutting tool, which is arranged on a tool carrier, the latter being guided adjustably in a direction transverse to the conveying direction and parallel to the support, and which, with the aid of a resilient actuator for the tool carrier, can be positioned, with resilient prestressing, against that side wall of the ski being conveyed along the support which is to be machined.
