Automation of billet feeding is one of the key factors for increasing productivity in modern turning areas. The barfeeder eliminates downtime for bar replacement and ensures continuous processing, and the quality of the entire system depends on the accuracy and reliability of the collet.
The Tecnicrafts line includes three main types of collet for different mounting schemes:
- For the pin: they are selected for the diameter and length of the pin of a specific barfeeder. For rigid axial force transmission and minimal backlash.
- With internal thread: there are threads M4×0.7, M5×0.8, M6×0.75/1, M8×1, etc. (right and left threads). For easy installation and precise adjustment.
- With external thread: variants M3, M6x1, M8x1, etc. are common. For a firm fixation in the seat and vibration resistance.

The range of clamped diameters covers most typical tasks, from thin bars of 1 mm to workpieces up to 43 mm in diameter. The range includes designs for various threads (M3-M8, etc.), including those with left–hand threads, as well as options for specific machine models (JINN FA, NEXTURN, TORNOS, etc.).
Advantages of Tecnicrafts Collet
- high precision centering of the rod;
- stable fixation without slipping;
- vibration reduction and improved processing quality;
- Increased service life due to the use of wear-resistant steels and precise heat treatment.
The collet of the Tecnicrafts bar feeder is an important element of automated rod feeding, which directly affects the stability and accuracy of turning. A wide range of clamped diameters (from 1 to 43 mm), a variety of designs (for a pin, with internal and external threads) and compatibility with popular machine models allow you to choose a solution for almost any production task.
Due to the high centering accuracy, reliable fixation of the workpiece and vibration resistance, Tecnicrafts collets help minimize downtime, reduce waste and increase overall site productivity. And the use of wear-resistant steels and high-quality heat treatment ensures a long service life of the tooling even in intensive operating conditions.
Thus, the introduction of the Tecnicrafts collet as part of the barfeeder system is a rational step for enterprises striving for maximum automation and stable product quality.
