the smart tool control system spike® has already established itself in these processes

sensory tool holder spike® - from a 100% monitoring system to a machine operator-assistant solution

No matter whether you have small or large batch sizes, spike® is the smart tool holder for all user groups in the machinig industry - for monitoring, optimising and assisting the machine operator. spike® offers the ideal solution as a complete integration with a complex machine connection, but also as an assistance system via plug&play. The advantage of the spike® sensor system is that even most sensitive processes can be controlled and analysed in realtime. Additionally it shows the machine operator what the tool does at the moment. Since the end of 2018 spike® can even communicate directly with the machine.

The sensor system spike® is a measuring system which detects the cutting forces and moments directly on the tool. With the bending moment in X- and Y-direction, spike® can detect each cutting edge during the milling process. spike® is often used in machining procedures like milling, drilling, turning, grinding, grating, reaming, threading and FSW.

What is spike®_polar?

The patented spike®_polar provides the opportunity to compare the current state with the target state, which enables to diagnose a worn tool or an unbalance. spike®_polar can even detect chatter marks and also show process fluctuations. Additionaly it doesn´t miss out on dirt stacking on a blade or vibrations, because of the sensitive resolution of the bending moment.

Thereby deviation of dimension- and surface tolerance due to tool wear or fluctuating tool performance can be identified - And that enables to initiate an automatic tool change before a quality problem emerges.


Example 1: wear detection for each cutting edge

Example 2: mistake during drilling
