Innovative Solutions

The outstanding geometry of the SPC Series SIP is the result of an exacting finishing procedure applied by SIP since decades. In terms of precision, extensive manual labour brings perfection in detail to every single machine. The specialists at SIP are renowned for their extremely precise scraping technique. All critical machine elements are inspected for their accuracy and scraped accordingly. This time consuming process forms the basis of a stable structure with no inherent mechanical tension. The machine bed rests on 12 resp. 14 points, four of which serve as reference points. All mounting surfaces for precision-related machine components must be perfectly flat. Special attention is paid to accurate position and alignment of the axes. The machine assemblies representing the horizontal and vertical axes are installed afterwards. Again, their perpendicularity and parallelism against the machine bed are inspected and adjusted by further scraping.

The design concept of a machine is crucial in terms of heat related expansion. When in use, it is almost impossible to eliminate temperature fluctuations within the machine. On the SPC Series SIP, machine bed and rotary table have been designed symmetrically. Whenever possible, other machine elements were evenly arranged on both sides of the Z-axis.

Gear driven and motor spindles can be installed on the SPC Series SIP. Both spindles, the 10 000 rpm gear spindle and the 15 000 rpm motor spindle, can be equipped with different spindle tapers such as HSK-A100 or SK 50. The spindles are vector controlled, permitting tapping of threads without compensation chuck.

Implementation of a thermal management concept is vital for achieving precision. In this respect, the machine‘s symmetrical structure is of advantage. Already during the design stage, measures were introduced to keep heat sources away from the structural elements. The SPC Series SIP is equipped with a temperature-controlled cooling water system, which adapts itself to the temperature of the machine structure. Other components such as the milling spindle, the torque motor of the rotary table and the ball screws are cooled by water.

The NC rotary table with direct drive and a absolute high-quality rotary encoder offers ideal conditions for multisided and allover machining. A resolution of 0,001 degree on the encoder and a table speed up to 25 rpm provide for the desired precision. The acceleration of the rotary table is automatically adaptable to the workpiece mass, which is a standard feature on the SPC Series SIP. Pallets, ranging between 630 x 630 mm and 1000 x 800 mm in size, can be equipped with automatic docking systems for hydraulic pressures up to 240 bar.
