Repair of high speed steel reamer

In machining, drilling and reaming are often encountered. Drilling can only meet the general tolerance requirements. For the machining of holes with a precision of 9 or more, it is necessary to ream the reamer. In the reaming work, the most used is the W18Cr4V high speed steel reamer. After the high-speed steel reamer wears, the hole diameter of the hinged hole will be reduced, the surface roughness is poor, and the processing requirements cannot be met. For this reason, the reamer after the wear is repaired, and the specific method is as follows:

IECEx Approved Coriolis Mass Flow Meter

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Transmitter, Coriolis Mass Flow Transmitter, Coriolis Mass Flow Sensor, Mass Flow Sensor & Mass Flow Sensor Coriolis, ATEX, IECEx & CE approved.

The meter can be connected with computer as follows. Connect the meter and computer with a USB-to-RS485 converter( converter A+ end to transmitter A+ end, B- to B-, and GND to GDN); turn to device manager of the computer to check COM port connected with meter. Start the software, select the right COM port and click Connect; do not change any other parameters (if you do not know the right one, click Automatic options on the left, click Connect, plug & unplug the transmitter, and then check if it is connected). You can click Connect on the tool bar to disconnect or connect again. It will shown Connected/Not Connected at the bottom of this interface.

The flow direction is settable. There are 4 options, forward(default), reverse, absolute value & bi-direction. There is a direction mark on the sensor. Forward means the same direction with the mark on sensor, the meter will only count the flow in this direction; reverse means the opposite direction of the mark, the meter will only count the reverse direction; bidirectional means that the meter will measure both directions, it increases when it is forward and decreases when reverse; absolute means it increases no matter it is forward or reverse.
