HMP-150 Concrete Grinding Machine

I. Overview
This machine is driven by a rebound single element series motor, with gear reduction, circular column guide rail, and manual feed screw lifting. It has the advantages of small size, compact structure, simple operation, and good grinding quality. The quality of the ground specimens can reach CECO3, 88, YBJ209-86. The technical regulations for measuring the compressive strength of concrete by drilling core samples require the quality of the specimens to be ground flat. Therefore, it is widely used in the field of core sample grinding work.

2、 Main Technical Performance of HMP-150 Concrete Grinding Machine
1. Diameter of worn concrete: 50, 75, 100, 150mm
2. Grinding concrete core sample height: 47.5-215mm
3. Grinding head speed: 3400r/min Grinding head diameter: 120mm Grinding head end face runout: 0.10mm
4. Verticality error between fixture square hole and chassis plane: 0.01mm
5. Parallelism between the end face of the grinding head and the plane of the chassis: 0.10mm
6. Rated power of motor: 1.7kw
7. Dimensions: 550X420X700mm

3、 Grinding mechanism construction and principle
1. The structure of the grinding machine is mainly composed of three parts: rebound single-phase serial machine electric, gearbox, grinding head body, column, screw, lifting handle and dial, as well as chassis, fixture, and foot screw. The machine is easy to clamp concrete core samples, has high accuracy, good grinding quality, simple operation, and is safe and reliable.
2. Working principle: This machine relies on a flat grinding head equipped with diamond cutting tools to achieve the end face grinding of concrete core samples at a given speed. The machine adopts a circular column guide rail and a screw lifting manual feeding method to ensure smooth and reliable operation of the grinding head.

4、 Usage:
1. Select the corresponding fixture based on the diameter of the core sample and firmly clamp it onto the small circular column.
2. Loosen the main body fixing bolt, rotate the screw lifting handle, select the required size, and tighten the dial.
3. Open the inlet valve to allow water to flow, place the splash guard and close the power switch to rotate the grinding head.
4. The main body of the hand is slowly approaching the core sample and starting to sharpen, repeating several times.
5. Loosen the small round column and the ingot screw of the fixture, install the piece firmly in reverse, repeat steps 2, 3, and 4 until the core sample end face meets the requirements.
