CONSTANT CONTROL OF PRODUCTS
The manufacturer ensures the application of appropriate procedures in the design and manufacture of its products. The aim of these activities is to ensure the appropriate quality, repeatability and safety of ANDRE grinding tools.
Starting from the abrasive grain itself, the bond, through production and to the finished product warehouse
Raw materials, used in the manufacture of abrasive tools, undergo preliminary tests, already at the stage of receipt at the warehouse. Only after approval they can be used to prepare a mixture with the right composition.
In order to maintain optimum product quality at the various stages of production (preparation of mixtures, press forming, firing, etc.), production processes are supervised in detail. Not only the correct settings of machines and equipment is important but also the right conditions of mixture seasoning and optimally selected firing parameters.
Safety without compromise
Actions that are a must
Before the products are put into storage, they undergo a quality inspection aimed at detecting any possible defects.
The inspection of products always involves several stages, although it varies depending on the product range.
First, a visual inspection is carried out and in the case of vitrified bond tools additional sound method is used. It is checked if there are no visible scratches, cracks, chipping and in the case of the sound method, the grinding wheel is tapped to check the type of sound it makes. A properly bonded tool should make clear sound, a damaged one - a muffled sound.
The individual dimensions of the grinding wheels are further verified. With the use of a special measuring device the hardness of the grinding tool is tested. The modulus of elasticity is also checked using electronic non-destructive testing equipment. Grinding wheels are also checked for their allowable unbalance and rotational speed by conducting tests for test speed and burst speed.
Safety and performance testing of abrasive tools
In addition to standard inspection procedures, ANDRE products undergo extensive performance testing.
ANDRE's products are subjected to successive optimization in terms of both quality and performance. Detailed inspection of products, being a part of the manufacturing process, does not end the story. The tools are also subjected to performance tests, where their safety and efficiency are verified during intensive operation.
Performance testing on the one hand is the testing of implemented technological solutions, and on the other hand is the ongoing verification of the quality and safety of ANDRE products.
Storage and shipping
With special care until handed over to the customer
Proper storage and transportation of abrasive tools is one of the important elements affecting product safety.
Grinding wheels, although characterized by high dynamic tensile strength, are sensitive to impacts, falls, bending stresses and for these reasons require particularly careful handling.
At ANDRE's warehouses, products are stored in optimal conditions, including proper temperature, ventilation and finally room humidity.
The product shipped to the customer is properly protected and packed, so that it reaches the "hands" of the user without damage.
