Granite Mechanical Components and Operating Plate
Laser cutting& engraving is one of the most versatile technologies for material processing. The ability to process a wide range of materials gives lasers the advantage over other conventional processes. High Added Value Without Additional Costs The increasing use of granite in mechanical engineering is not so much due to the massive increase in the price of steel. Rather, it is because the added value for the machine tool achieved with a machine bed made of granite is possible at very little or no extra cost. This is proven by cost comparisons of well-known machine tool manufacturers in Germany and Europe. The considerable gain in thermodynamic stability, vibration damping and long-term precision made possible by granite cannot be achieved with a cast iron or steel bed, or only at relatively high cost. For example, thermal errors can account for up to 75% of the total error of a machine, with compensation often attempted for by software - with moderate success. Due to its low thermal conductivity, granite is the better foundation for long-term precision. With a tolerance of 1 μm, granite easily meets the flatness requirements according to DIN 876 for the degree of accuracy 00. With a value of 6 on the hardness scale 1 to 10, it is extremely hard, and with its specific weight of 2.8g/cm³ it almost reaches the value of aluminium. This also results in additional advantages such as higher feed rates, higher axis accelerations and an extension of the tool life for cutting machine tools. Thus, the change from a cast bed to a granite machine bed moves the machine tool in question into the high-end class in terms of precision and performance - at no extra cost.
RFQ
1.Can I order one piece granite surface plate?
if you want small size less than 800x800,it's would delivery by air express. mos times express cost is higher than granite cost.
so we don't suggest you buy one small size from us.
2. if your granite surface plate have certifications ?
Yes , each of granite surface plate has it's certification.if you need we can send sample for you
3. How much does granite surface plate weight?
(Lengthx width xHeight )mmx3x1000= weight granite kg
4. why dose granite have color steaks,spots and seams ?
Seams and color streaks occur occasionlly&naturally in granite stone. it is not uncommon for granite plates of large sizes to
include cosmetic non-conformities,which we endeavor to keep to a minimum. we can assure you that such visible disconformities are
carefully examined before,during and after the manufacturing process for actual or potential problems due to non-conforming
material. Our goal during this inspection process is to insure that we are following our own internal quality standards.
5. Can you put my company name and logo on your product ?
How should I clean my precision granite products
6.Why I get the granite accuracy is not good ?
Due to different temperature granite accuracy wil be change , before you use it,please put it in a uniform temperature space over
24hours, it's request temperature (20 ±5 )ºC
