Hi @workID
You have several options for doing this out of the box in Magento. Depending on how many products you have in the end. You can technically setup a Configurable product with two Attributes one for Machine Manufacturer and one for Machine Type, and then add all your Grinders, as Associated products.
You can add these attributes in the admin under:
Catalog > Attributes > Manage Attributes
Under Scope, select Global
Under Catalog Input Type for Store Owner, select Dropdown
Now you have an option to make it a configurable attribute.
When you are done creating your attributes go to
Catalog > Attributes > Manage Attribute Sets
And add your attributes to the attribute set you wish to use (properly default).
When you create the configurabel product you select that you want to use these two attributes.
If you need to have multiple grinders, you can use either the Category structure to filter down your customers choices. Or again adding attributes that let customers select What machine and type they are looking for in the Magento Layered Navigation.
You add layered navigation attributes also by creating a new attribute as a dropdown or multiselect, and selecting "Use In Layered Navigation" when creating or editing the attribute.
I hope this helps you, feel free to ask if you have any further questions :-)
