Tool Setter for CNC Lathes [H4E Series]

Tool Setter for CNC Lathes H4E Series

Originating the blade of CNC Lathe

The H4E series is equipped on CNC lathes and machining centers to preset the blade, and also performs wear, chipping, and thermal displacement compensation, contributing to maintaining the constant machining precision of the machine tool.
This series has smaller contact-surface than our H4A series and is ideal for locations where space is limited.

Features

Compact swing type capable of detection in 4 directions

Tool detection is available in 4 directions.
This series has smaller contact-surface than the H4A series and is ideal for locations where space is limited.
*The contact-surface diameter is smaller than H4A.

Repeatability of 1μm and coolant-resistant IP67 protection rating spec.

It performs speedy and automatic tool measurement before starting machining and in-machine tool compensation during the machining cycle.
The IP67 rating ensures high-precision detection even in adverse environments where coolant is applied, contributing to time savings in tool setting.

High reliability + Low cost: Fewer false detection achieved by touch sensor method

Since the detection is made by direct contact with the tool’s leading edge, coolant splatter or mist is less likely to interfere when comparing with expensive non-contact sensors (e.g., laser sensors), thus ensuring high reliability.

Circuit Diagram

Notes:

Since the built-in contact point serves as the swing fulcrum, extremely fast operation speeds will accelerate contact deterioration. Since contact point materials with low electrical resistance cannot be used, please ensure contact point durability by energizing them only during measurement.
Please do not press the contact point hard to the limit of operation. Also, please do not push the contact downward from above.
Do not use at an operating speed of 10 mm/min or less.
