Work screw-cutting lathe. Screw-cutting lathe works as follows: its main body as a whole is stationary, the tool set in motion a kind of head. Workpiece, which is obtained as a result, can be used in subsequent operations. Operation of metal-cutting lathe machine today is not optimal. Rate of processing of materials (metal, plastic) is not as effective as it I would like. But the product that results from the work defies criticism. Turning and vintoreznyystanok axis – a new tool that has gained popularity among industrial workers.
Lathe axis (RAM) combines the features of standard lathes with Quill-style line. The principle of operation of this type of tool is pretty simple: when docking with the processed material, it glides over its surface. It quality makes the job easy, fast, and most importantly – quality. Screw-cutting lathe combination. Its main feature – a function of drilling. These machines are characterized by high slip and have in their presence carriage.
Screw-cutting lathe-type CNC – can replace old machines, for example, and other CNC multishpindel characterized by simple installation and easy operation. They are 100% responsible modern development workers places, and its performance can only envy. Buying such a machine – the best choice for solving production problems.

Monolithic pier foundation for a wooden house on moving and heaving soils, peatlands, and deviations recommend installing columnar-transom (rostverkovy) monolithic foundation. This is an economical option – something between full height and melkozaglublennym monolithic foundation. Monolithic pier foundation is recommended in soils where the groundwater level lies at a depth of 1 meter from the level of the soil surface, ie in the absence of a drilled well water. When designing a foundation for a given perimeter every 2-2.5 meters starter and poured piles of diameter 250-280mm. Under the grillage, located above the level land at 15-20cm, set the jumpers. Piles starter until about 1,5-1.7 m, that is, to a depth of freezing.
The impact of environment on the foundations is minimized due to the small cross-sectional area of pillars at the expense of covering side of the base material reduce friction and heat insulation of the surface layer of soil around the foundation design. Keep in mind that building a home and putting it into operation should be carried out in one construction season. Built on heaving soils, and left without foundation load inevitably deformed. Particular attention should be paid to waterproofing. Paint or waterproofing okleechnoy successfully keep the foundation from the effects of groundwater. Additional costs arise when the device monolithic columnar base, due to the need to manufacture and installation of reinforcement cages, formwork, grillage, preparing and placing concrete. Reinforcing harness is required in order to column is not severed when the seasonal shifting of the soil. Just when the device monolithic pier foundation formwork is required – it may be different in shape, square or round. But between the formwork and the walls of the pit required a gap of at least 10 cm, in which after removal of the formwork will fill sand or gravel – to avoid the impact of ground movements Pole foundation.
