Why choose TJR
TJR Value Added Features
|Table rotation rate||
High table speed, high efficiency
The equivalent of AR-125
The equivalent of HR-255
|After service-support in China||Experienced after-service technicians located in China provide prompt services.||Lacking local after-service supports|
|Water Resistance||Watertight by all rims sealed with O-ring
Protect class: IP65
|Manually smear connections with waterproof glue|
|Diameter of Table central hole||Large bore is the TJR standard for the entire product line||Large bore is an optional extra|
The unique selling point of TJR worm gear
|The worm gear material||Made in Japan, High tensile brass with Japanese unique formula.
Its strength is better than ferroalloy.
|Aluminum Bronze (ALBC3/ALBC1) or Phosphor Bronze (PBC2PBC3)|
|Abrasion resistance||The abrasion resistance of High tensile brass:
25.1 mg/cm2 per 10,000m
Its estimated wear life is 2.6 times longer than that of Aluminum Bronze
|The abrasion resistance of Aluminum Bronze:
65.7mg/cm2 per 10,000m
|Wear Life||Normally 10 years of longer||At most 4 years|
The advantage of TJR spindle bearing
|Company A||Company B|
|Radial-axial preloading bearing||Taper roller bearing||Cross roller bearing|
|Can bear heavy cutting in the horizontal and verticaldirections||Can bear less heavy cutting||Can only bear light cutting|
Advanced inspection facilities
|2-Dimension coordinate measuring machine||Yes
|3-Dimension coordinate measuring machine||Yes
Fully utilized to test all kind of precision and runout
|Laser interferometer and rotary axis calibrator||Yes
Every TJR rotary table needs to pass the test by the laser angular position measurement system before shipment
Some companies only use normal optical auto-collimators or height gauge collocating with fixture to test.
High performance braking mechanism
|Method||Use the full circumference braking and clamping mechanism. The braking mechanism is designed with full 360∘circumference hydraulic clamping.
||Use the conventional disk braking systems.
