AK-Grinder - the grinder with automatic tracking function

AK-Grinder - the grinder with automatic tracking function

Grinder application pressure is maintained at a constant rate while grinding is carried out automatically. Application pressure can be arbitrarily set, allowing for optimal pressures for a wide variety of work from deep grinding to stripping and other light grinding.

Automatically tracks the grinding surface even if there is welding deformation or other issues allowing for a uniform finished surface.

A high precision tracking control device developed by Aichi Sangyo
▪ Allows for easy-to-use automatic operation

▪ Tracks surfaces accurately even if there is any convex or concave deformation 

▪ Automatically stops if load increases to prevent grindstone damage and grinder burn out

Strong, high speed rotation cutting grinder
▪ Uses a high frequency control method and can use Φ 180 and Φ 100 millimeter grindstones

▪ Also allows for high speed grinding of steel and stainless steel welding beads at a rate of 45 to 60 grams per minute

Aichi Sangyo recommended Eisenblatter brand flap discs
▪ Equipped with German Eisenblatter brand high efficiency flap disc grindstones

▪ Radial laminated structure maintains a uniform polish on the grinding surface

▪ No grindstone clogs even during high speed reciprocal cutting

Robot mounted type AK-G04
Can be equipped on 20 kilogram and larger portable robots to suit various robot types. Because it is robot mounted, it can be used for grinding of complex sections such as bends, right angles, and curves by construction grinding programs. Grinders can be produced in two types: Φ 180 and Φ 100 millimeter type. Vertical slide for tracking will always return to the same position (height) via a home position return signal. Allows for creation of high efficiency and high safety processing programs. Also allows for multi machine handling through use of a tool changer. Vehicle body and propeller shape grinding, deburring. Shared vertical tracking slide mechanism; Φ 180 and Φ 100 millimeter high frequency grinder.

Orbima TIG 500II welding power source:

●Secondary side output precision guarantee

Guarantees welding parameters are maintained within ±1% of the secondary output side set values to ensure reproducible welding quality. *There may be exceptions for some conditions.


●Low heat input and low strain welding joint guarantee

Ensures low heat input and low strain welding joints through low pulse, synchro pulse, and other pulse waveform control.


●Powerful 500 A rated (at 100% usage ratio) design

Also allows for welding of plates of 500 mm thickness and above through installation of a 500 A rated inverter transformer.


●Stable arc starting up to 70 m extension

Utilizes a touch start arc start method which achieves good startability at secondary cable lengths of up to 70 m.


●Welding heads can be provided to suit your applications

Features a built-in 4 axis DC servo motor driver and welding heads can be designed to order.


Programmable controller

●Easy welding condition management through use of an LCD touch panel
