Cradle type CNC 5 axis rotary table with Hydraulic brake RT250
Silver-RT250 5 axis rotary table advantages:
1, No backlash
Through the roller and CAM rolling contact, no forward and reverse
back gap problem, greatly improve the roller CAM ultra-precision
characteristics, reduce the rate of defects, improve the quality of
precision machining technology is a breakthrough.
2, Ultra high efficiency conduction
Roller CAM type turntable in rolling way conduction, reduce wear,
conduction efficiency is high, high speed operation, conduction
efficiency is up to 90% above.
3, There is no thermal displacement
Even under high speed operation, reduce friction, reduce heat
displacement, improve quality stability, reduce the rate of
defects.
4, Free maintenance
Due to low abrasion and minimal aging, the initial precision can be
maintained for a long time.
5, Life is long
Roller conduction mode, can reduce wear, long service life.
6, The brake performance
During the positioning of the brake, the disc surface will not
shake from side to side, and the positioning brake will be kept
within 2um, which can highly show the precision machining quality.
Application Area:
This five-axis rotary table is mainly used for machine tools with
850 strokes. The processing method that requires multiple clamping
and multiple processes is successfully reduced to complete most or
all of the processing procedures in one clamping, so as to improve
the processing accuracy, shorten the processing cycle and save
human and material costs, Mainly used in the following industries
and products:
1. Precision parts
2. Medical equipment
3. Space blades
4. Aerospace defense industry
