HB-3000MS Automatic Measuring Briness Hardness Tester

Short Description:

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.

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.

Measuring system introduction

This system has both manual and fully automatic measurement functions. Makes the operation very simple and reliable. As shown below:

Soft operate

As long as the indentation appears in the screen area without any operation, the indentation diameter and hardness value will be displayed on the upper right.

LCD large flat screen

Using large-screen flat LCD touch screen. Simply click with the mouse to select the program; the interface is clear and there is no visual error, it can display the holding time of the indentation image, the test force, the objective lens, the indenter selection, the distance measurement, the hardness value conversion, and the report output data.

The system can accurately distinguish Brinell indentation images in complex backgrounds. The following pictures are measurement images of various complex backgrounds.
