Granitek precision granite castings
Article number: G-135
Granitek Ltd. is the only privately-owned company in the UK manufacturing Precision Granite Castings. Granitek has many years experience in manufacturing components from a few kilos up to several tonnes in weight, and for a wide variety of industry sectors including machine tools, metrology, semiconductor, medical, photo-imaging, pre-press, laser engraving and ship building. With its customers spread across three continents, Granitek’s experienced engineers can offer help with all aspects of design.
Extra information:
Granitek Precision Granite Castings are produced by using granite aggregates. Crushed, river washed, kiln-dried and mixed with an epoxy resin system to form a casting which can be moulded into complicated shapes. All necessary threaded inserts, pipes, hydraulic pipes, etc., can be cast into the component to an accuracy only dependent upon mould manufacture.
Granitek Precision Granite Castings give the following distinctive benefits:
• Reduced assembly costs
• Competitive price
• Excellent vibration damping
(8 to 10 times better than cast iron)
• Improved thermal stability
• High strength to weight ratio
• High static, dynamic, torsional stiffness
• Excellent noise absorption
• Minimal post-cast machining
MYTRI will work with your company closely from concept through detailed design to finished casting if required.
Metrology tables, columns, precision ground, to accuraciesof less than 2 µ can be achieved. Machine tools like milling, grinding, boring, lapping, drilling, etc. can all benefit from a Granitek precision granite cast bases.
Steel fabrications for bed structures and columns often prove not stiff enough statically and dynamically, taking into consideration the demands for increased performance of todays’ machines. In certain cases the use of Precision Granite Castings may not be economical because of small production runs, mould costs or some other technical constraints.
In this case an inexpensive method of filling the welded fabrication with Granitek material is used to give the advantages you would expect from a Precision Granite Casting. Examples of Precision Granite Castings are too numerous to list them all.
