FloorPlates

STOLLE floor plates - mounted work holding plates - Floor plates - are made from a special cast iron / steel alloy giving a Brinell hardness of 180 - 200.
The tensile strengh varies between 260 - 300 N/mm².
Exceptional stability is achieved by Stolle´s rib pattern and design together with controlled cooling, after casting, by sophisticated core design resulting in minimal cooling stresses and maximum stability of the plates.
These manufacturing techniques developed by Stolle result in plates that will maintain distortion free accuracy providing they are stored and installed correctly.
The top surface is machined to the different flatness accuracies of DIN 876, as required.

 
T- slots are machined to DIN 650 H12 fit as standard, with popular sizes such as 22,28,36 or 42 mm wide, for T- nut sizes M20,M24,M30 and M36 respectively. T- slots can be machined to width tolerance H7 or H8 at extra cost. Depth of T- slots can also be increased in cases of extremely high pull- out loads.
Cast pockets, as required, are provided along the T- slot enable fitting and removal of T- nuts and bolts.
 
The position of the levelling units and the plate overall hight is determined by the nature of component and work loads. Reinforcing ribs have a sloping T-section at their outer ends to improve torsional and fatigue strength.
 
Customary T- slot distances are 150, 200, 250 or 300 mm to each other.
T- slots can be machined in longditudinal and transversal direction depending on your requirements as well as threaded holes and fitting holes.
