6. Background Information
The differences between electric spindle and mechanical spindle,
Drive method. The electrical spindle is driven by electric motors,
which is adjusted by the inverter to adjust the speed and torque,
which is suitable for high speed and high precision applications.
The mechanical spindle uses traditional mechanical devices, such as
belts and gears to achieve speed adjustment.
Scope of application processing. Due to its high accuracy and high
efficiency, the main shaft is suitable for high-precision and
high-speed processing fields such as CNC machine tools and high
-speed cutting processing centers; the mechanical spindle is more
suitable for areas with low -speed processing, simple operation,
and low cost.
Maintenance costs. Due to the relatively complicated maintenance
and maintenance of electrical components, the electrical main shaft
requires more manpower and financial investment; the maintenance
cost of mechanical main axis is low, the structure is simple, and
it is relatively easy to maintain.
External structure. The main shaft is usually more compact and
beautiful than the mechanical spindle, and the performance is more
stable and reliable.
Speed adjustment method. Electric main shafts can easily adjust the
speed by adjusting the frequency to achieve the speed adjustment;
the mechanical spindle needs to be adjusted by changing gears or
leather.
Anti-interference ability and reliability. Electric main shafts are
susceptible to external interference, and are controlled more
complicated; the main axis of the mechanical axis is less
interference, long-term use of stable performance, and high
reliability.
Manufacturing complexity. The electrical main shaft manufacturing
process is more complicated, but it can control the precision
control of processing through the electronic controller, which is
suitable for large -scale production; the mechanical main shaft
manufacturing process is relatively simple, but it has high
requirements for manufacturing accuracy.
Technical characteristics of electric spindle bearings.
Rolling bearing is the most widely used bearing for electric
spindles in the market.
Because the maximum speed of the electric spindle depends on the
function, size, structure and lubrication method of the bearings,
the bearing must have the advantages of high speed performance,
high dynamic load capacity, good lubrication performance, and small
heating etc. Electric spindles mainly use rolling bearing, sliding
bearing.
At present, the most widely used bearing in the market is the
rolling bearing of ceramic balls. This is mainly because the
ceramics have the advantages of small density, good rigidity, and
small thermal expansion coefficients. The sliding bearing is larger
in heating, so not widely used.
