A powerful, precise turbine grinder built for continuous industrial grinding with multiple wheel options.
Atlas Copco GTG40 is a family of pneumatic turbine grinders for grinding, material removal, and heavy-duty industrial finishing.
The range offers different speed and configuration options so the tool can be matched to the wheel type, the application, and the demands of the production line.
How do I choose the right GTG40 model?
Step 1: Identify the wheel type used in your application.
Step 2: Select the speed that fits the task and workpiece.
Step 3: Check the air inlet thread and hose connection used on your installation.
Step 4: Confirm the exact ordering number before purchase.
Which wheel types are supported?
The family includes models for Type 11 cup wheels and Type 27 depressed center wheels.
The grinder model should always match the wheel type used in the application.
Are there differences in speed across the range?
Yes.
The family includes 6,000 rpm and 8,500 rpm free-speed models.
The right choice depends on the grinding task, wheel type, and material removal needs.
What should I check on the air supply side?
Check the BSP or NPT air inlet thread and the required air hose size.
This ensures the grinder matches the existing plant air setup.
Are all GTG40 models the same in terms of accessories?
No.
Some models are intended for a specific wheel type, so the grinder model, wheel type, and ordering number should be matched carefully.
How should a turbine grinder like this be maintained?
Keep the air supply clean and stable, verify wheel compatibility before use, and inspect the spindle and connections regularly as part of routine tool maintenance.
