HB-3000MS Automatic Briness Hardness Tester
HB-3000MS Brinell hardness tester adopts the latest fully automatic closed-loop
sensor control technology,the stepless servo motor directly drives the ball screw to
increase the force, and the force sensor closed-loop to feedback the force process and the
size to the micro-grading, which will be permanently eliminated the traditional weight lever
amplification loading system with the increase of use time due to hydraulic or motor
deceleration error, or spindle knife edge friction caused by over loading or less loading
fluctuations. The test force of this machine is from 62.5 to 3000Kgf, which can realize
automatic measurement of Brinell hardness indentation.
1.Features:
The portal frame structure can test the hardness of large workpieces (customized).
Using a dedicated numerical control system, a closed-loop electronic control system exerts
the test force. The transmission part of the whole machine is completely composed of a
stepping motor and a ball screw.The failure rate of the whole machine is low, maintenance is time-saving and labor-saving,
and no hydraulic oil is required.It is stable and reliable when used in environments with
large temperature differences.
Application: It is suitable for the hardness test of cast iron, steel, non-ferrous metals and
soft alloys, and also for the hardness test of some non-metallic materials such as hard
plastics and bakelite.
Loading mechanism: Fully closed-loop control sensor loading technology is adopted,
without any load impact error, monitoring frequency is 100HZ, and the internal control
accuracy of the whole process reaches 0.5%; the loading system is directly connected to
the load sensor without any intermediate structure, and the load sensor directly measures
the load of the monitoring pressure head for adjusting, the coaxial loading technology, no
lever structure, not affected by friction and other factors; the unconventional closed-loop
control system of the lead screw lifting loading system, the double linear frictionless
bearing executes the probe stroke, almost no need to consider the aging and errors
caused by any screw system;
Electrical control mechanism: high-end electrical control box, well-known brand
electrical components, servo control system etc.
Safety protection device: all strokes adopt limit switches to ensure the operation of the
equipment in the safe interval; except for the necessary exposed components, the rest
adopts a covered structure.
Operation and display: computer touch screen control, ergonomic design, beautiful and
practical.
Indentation measurement & reading: Fully automatic Brinell hardness measurement
system.
