Product outline

Quantifying of grip force in metalworking Daily management tool to support precision machining

GRIP MASTER is a tool to quantify grip force in metalworking, while measuring and managing a stabilized metalworking process.
Grip force of drill bits or work can be properly managed, preventive maintenance of machine tools, improvement of machining quality are made possible.
Huge line up of sensor probe from φ4 to φ32 are available, besides that various functions such as memory function ensures an easy management of grip force.


Safe and easy inspection with quantified grip force

Grip force of tool holders can be easily checked by simply inserting and gripping the sensor probe by a tool holder.


Did you know that tool holders also have lifespan?

It does not mean that the same grip force is applied always, even if tools are set in a usual way.
Gripping force of tool holders changes over time due to wear and over use. Especially, gripping force of a hydraulic chuck declines over time depending on usage.
Then, if not enough grip force is applied, it may lower machining accuracy and may cause damage on products, lowering productivity a lot.

■By checking the grip force of tool holders, you can…

1)check if enough force is applied to hold bits.

2)detect deterioration of tool holders in advance

■Prevent damage and problems during metalworking process!


A variety of sensor probe product lines

φ4 to φ32 supported
GRIPMASTER_p

Ideal for hydraulic chuck

Gripping force of tool and work holders can be checked regularly to maintain the runout accuracy.


No calibration required

Information of the sensor is stored in the memory of the sensor probe itself.
There is no need to enter information for calibration each time when a sensor probe is changed.

Easy data recording by pressing “SAVE” button

Measurement data will be recorded with date and time when “SAVE” button is pressed.
Recorded data can be easily exported to PC via USB interface.
