Precision parts from granite according to customer drawings

Granite - A modern material for high-precision parts

High-precision components can be ideally manufactured in granite. The reasons for this are primarily the extremely good properties of this material. Natural hard stone is the ideal basis for the manufacture of precision products due to its fine crystalline structure, low coefficient of expansion, high abrasion resistance, optimum vibration damping and freedom from unwanted internal stresses. Very fine surface quality can be achieved when machining hard stone. This makes granite parts particularly suitable for air-bearing guides. The air consumption is reduced to a minimum due to the high surface quality. In any case, the use of granite is always worthwhile when the quantities of parts, such as machine beds or high-precision base plates for guides, are relatively small. If the quantities are over 50 per year, the use of polymer concrete can be considered. We can also make you an offer for polymer concrete. However, please note the high initial costs due to the production of the mould.

With competitive price and timely delivery, CHENGXINRUN sincerely hope to be your supplier and partner.


Comparison of the material properties of granite and competing materials like polymer concrete or cast iron

Property Unit Granite Polymer concrete Steel Cast Iron density kg/dm³ 2,9 2,1 - 2,4 7,85 7,15 Bending Strength N/mm² 13 25 - 35 300 - 600 290 Compressive strength N/mm² 250 100 - 180 260 - 1200 720 - 1150 Linear expansion µm/(m°K) 5 - 7 12 - 20 12 10 Thermal conductivity W/(m°K) 3,0 1,3 - 2,0 50 50 Special heat capacity J/(kg°K) 845 900 - 1100 500 500 Modulus of elasticity kN/mm² 60 - 90 30 - 40 210 88 - 113

In addition to the properties shown in Table 1, there are other advantages to using hard stone:

  • Vickers hardness 850-900 (harder than steel)
  • low linear coefficient of expansion
  • the specific weight is comparable to that of aluminum
  • the elasticity comparable to that of cast iron
  • no burr formation
  • non-magnetic
  • tension-free
  • not conductive

  • Background information on granite

    Magmatic rocks are formed by cooling hot molten material from the earth's interior, the so-called magma. If the cooling takes place underground, one speaks of plutonites or intrusive rocks. Due to the relatively good thermal insulation of the overlying rocks, the molten magma cools down only slowly so that large mineral crystals can be formed. Examples of plutonic rocks are granite or gabbro. The magma can form huge rock masses, the so-called plutons, which often contain several thousand cubic kilometers of rock Granites (from Ital. granito, "granulated") are massive, relatively coarse-crystalline, magmatic deep rocks (plutonites), which are rich in quartz and feldspars, but also contain dark minerals, for example mica. The phrase feldspar, quartz and mica, the three I never forget, gives a somewhat simplified description of the composition of granite. Translated with www.DeepL.com/Translator (free version)


    Creative edging ideas with granite setts for your garden

    Exploring edging designs with granite setts

    Granite setts, particularly those like granite kerbs, open up a realm of creative possibilities for garden edging. These durable and visually appealing stones are versatile enough to fit a variety of design aesthetics, from the elegantly simple to the intricately artistic.

    For more information, please visit Custom Made Granite Kerbs.

    A popular use of granite kerbs is in crafting straight, clean-lined borders. These create a clear demarcation between different sections of the garden, such as dividing the lawn area from flower beds or delineating pathways. This approach not only offers a sleek and organized appearance but also serves practical functions like soil retention and mulch containment.

    For gardens seeking a more fluid and organic feel, granite setts can be arranged in curving or undulating patterns. These designs are effective in forging smooth transitions between diverse garden zones, such as leading from a manicured lawn to a more relaxed wildflower area. The ability of granite setts to adapt to different shapes and forms allows gardeners to express their creativity and personalize their outdoor spaces.

    Experimenting with varied colours and textures of granite setts can further enhance the aesthetic appeal of garden edging. Utilizing contrasting shades can accentuate particular features or areas, while incorporating different textures can introduce an additional layer of visual interest and depth.

    Granite setts, including kerbs, are not just decorative elements; they also play a crucial role in the structural integrity and maintenance of garden landscapes. By establishing well-defined edges, they help in effectively managing plant growth and maintaining the neatness of garden materials, thereby simplifying garden care and upkeep.

    Additionally, granite setts are highly resilient to weather elements and general wear, ensuring that the garden’s edging remains intact and appealing over time. Their low maintenance requirements make them a practical choice for busy homeowners who desire a beautiful garden without the constant upkeep.
