Diamond sawblades for abrasive stone..
 There is a wide variety of abrasive stone materials, in particular sedimentary stone:
- sandstone;
- basalt lava;
- porphyry;
- tuff;
- shelly limestone, sandy;
- travertine, sandy/porous.
The fluctuations of a material occurring in one deposit may produce many different variants with respect to colour, compressive strength, grain size, porosity, etc.
In regions where sandstone occurs, this has been a very popular and frequently used material in the past. It has been used for many historic buildings, mostly in massive sandstone construction (castles, churches, museums, and also residences and palaces).
Frauenkirche in Dresden
 The Frauenkirche (Church of Our Lady) in Dresden is one of the most spectacular building projects currently in progress.
- Built: 1726 - 1743
- Destroyed: February 1945
- Reconstruction: 27 May 1994 to 2006
- Material: Postaer
The  Frauenkirche was largely destroyed by bombs in 1945. The only parts that remained intact were the remains of two pillars and some vaulting. The reconstruction is being carried out with material from the original quarries, which are still operated today. The design work has been done with highly sophisticated computer technology.
 The material is cut and machined with diamond tools, using tools such as large circular saws, frame sawing machines, sawing and gantry sawing machines, milling machines, etc.
About 70% of the diamond tools required for this purpose are supplied by WINTERSTONE.

Core material for blades
 Up to a diameter of 500mm, mostly close-pitch cores are used; from 500 to 800mm mostly widely spaced toothed cores; for larger diameters, almost exclusively widely-spaced toothed cores.
The abrasive materials cause a very high wear rate on the steel core during the cutting process, so that the teeth of the core tend to become "pointed". There are some materials, such as basalt lava or coarse-grained sandstone, where the number of possible re-tippings is reduced to between three and five.
Segmented Sawblade
The answer to these problems is the segmented sawblade available exclusively from WINTERSTONE. This core minimises the risk of accident and increases the number of possible re-tippings. It prevents tooth thinning. At the same time, it reduces noise level by about 12dB.
There are several types of core available form WINTERSTONE simply for noise reduction, for use on less abrasive materials. For all diameters from 700mm upwards, we recommend the TECHNO core, for reasons of cost. |
