Rotation Speed Testing Machine

 
1）  Application :
Diameter：100-400cutting disc, 100-230mm grinding wheel , thickness: 1-7mm
2）  The machine body adopts box structure and strengthens the shock absorption design. The maximum noise is ≤80 decibels.
3）  The mechanical and electronic double lock of the rotary box door effectively avoids the accident caused by the unintentional opening of the box door during operation.
4）  using 4kw, 2-pole motor, the application of advanced frequency control technology, good control characteristics.
5）  The controller adopts a wide-width switching power supply in the controller to make the control system work reliably between 180v and 260v.
6）  The automatic magnetic card driven by DC motor automatically locks the spindle when loading and unloading the grinding wheel, which is stable and reliable.
7）  high-sensitivity speed sensor, measurable range of 20 ~ 40,000 rev / min, accuracy ± 0.01%, resolution of up to ± 1 rev / min.
8）  using high-precision speed setter, set the speed accuracy of 1 rev / min, display accuracy ± 1 rev / min.
9）  delay time 8 blocks, range 0 ~ 9999 seconds, error ≤ ± 0.01%, digital display set time and current running time.
10）  the spindle radial runout ≤ 0.03 mm.
11）   All-round protection for motor overload, motor overheating, box door opening during operation, automatic related processing and indication of fault conditions, and sound alarm.
12）  All latching switches are non-contact electronic proximity switches, which are dustproof, anticorrosive and oil resistant, with long service life and high reliability.
13）  The broken sensor adopts floating detection technology, which effectively improves the detection sensitivity and anti-interference performance.
14）  The automatic recorder can print the swivel data at any time for analysis and archiving. Simple print and full print can be set.
15）  fully automatic operation, highly intelligent. The acceleration/deceleration curve is automatically generated and automatically started, constant speed, delay, braking, automatic braking and recording, automatic recording of the recorder, automatic fault detection and processing. The user only needs to set the speed and time and then press the start button
