In the numerical control transformation the
main mechanical part reequips the discussion
A
new numerical control engine bed Cnc machining, must achieve in the design that, Has the
high static dynamic rigidity; Movement vice- between friction coefficient
small, the transmission is ceaseless; The power is big; Is advantageous for the
operation and the service. When engine bed numerical control transformation
should meet the above requirements as far as possible. Cannot think the
numerical control installment and the ordinary engine bed connects in has met
the numerical control engine bed requirements together, but also should carry
on the corresponding transformation to the major component to enable it to
achieve the certain design request, can obtain the anticipated transformation
goal
Skids guide rail
Cnc machining Said to the numerical control lathe that, the
guide rail besides should have the conventional lathe guidance precision and
the technology capability, but also must have good bears the friction, the
attrition characteristic, and the reduction but sends the dead area because of
the friction drag. At the same time must have the enough rigidity, by reduces
the guide rail to distort to processes the precision the influence, must have
the reasonable guide rail protection and the lubrication
Gear
Cnc machining The
common engine bed gear mainly concentrates in the headstock and the gear box.
In order to guarantee the transmission precision, on the numerical control
engine bed uses the gear precision class is all higher than the ordinary engine
bed. Must be able to achieve the ceaseless transmission in the structure, thus
transforms time, the engine bed main gear must satisfy the numerical control
engine bed the request, by guarantees the engine bed processing precision
