Mobile Phone Frame Double Disc Grinding Machine

Features and advantages of grinding machine:

High safety factor:

1. Workpiece jamming protection: In case of workpiece jamming, the feeding disc will automatically stop and give an alarm, which can effectively avoid casualties and damage to workpiece. It has received unanimous praise from operators on site. Workers can work safely.

2. Grinding wheel limit protection: In order to prevent the phenomenon of sparks when grinding between iron and iron, when the grinding wheel is consumed to the limit, the machine tool will automatically stop and give an alarm.

3. Safety interlocking device: Between the grinding wheel cover’s lifting-lowering and the rotation of the grinding wheel there is safety interlocking. Between trimming and grinding there is safety interlocking. The automation degree is high and safety factor is high.

4. High-altitude cable rack: The cable communication between the machine tool and the power distribution cabinet adopts high-altitude wiring. The ground is barrier-free. The cable is not easy to be damaged, and does not hinder the walking of personnel. The safety factor is high.

5. Alarm device: alarm and sound-light prompt can be realized in case of failure of each part of the machine.

6. Automatic lifting and lowering of the grinding wheel cover: one person can operate the boom to easily replace the grinding wheel, which is safe and fast.

Low cost of single workpiece:

1. High efficiency: There are more feeding position holes in the same feeding disc.  More workpieces can be processed in the same working time.

2. Less consumables: grinding wheel is the main consumables. The grinding wheel diameter is small and consumables is cheap.

3. The correction frequency is low: The machine tool adopts a special structure, so that the grinding wheel repairing times are reduced, and then the grinding wheel consumption is reduced.

4. The operation is simple and convenient: The replacement of feeding disc does not need to be disassembled in a big way when the feed disc is replaced for switching the variety. The feeding disc can be taken down easily only by loosening a screw bolt. The working time is saved.

5. No need of manual intervention: The grinding wheel trimming frequency can be preset. When the processing quantity of the machine tool reaches a set value, the grinding wheel automatically retreats for trimming and compensates. After  trimming is finished the grinding wheel automatically returns to the grinding position to start the feeding disc process for continuing grinding and then completes an automatic processing cycle. The whole grinding wheel trimming process does not need manual intervention.

6. Less labor: the machine tool has manual and automatic mode conversion. Due to the adequate safety protection of the machine tool, after switching to automatic mode, one person can operate the machine. The discharging conveyor belt is equipped with counting function, which can make accurate production statistics and machine calculation.

High precision and stability:

1. Heat insulation design: The design of the machine tool solves the influence of grinding heat on the deformation of the machine tool, and ensures that the machine tool can work continuously for a long time with good precision and stability.

2. Clearance elimination function: The machine tool is equipped with a hydraulic system, which can successfully eliminate the clearance of the ball screw, prolong the life of the screw, and keep the equipment in the best working condition all the time.

3. Grinding pre-tightening force: The double grinding heads rely on hydraulic pressure to provide uninterrupted maintenance of pre-tightening force, with stable precision. In case of special circumstances such as grinding wheel breakage, it can achieve safe avoidance to protect the machine tool. It is safe and reliable.

4. Strong rigidity: The grinding head adopts V-shaped steel inlaid needle bearing guide rail, and moves integrally instead of telescopic movement, which improves the rigidity to a maximum extent.

5. The main shaft only in charge of rotation:  The main shaft, only rotates, does not have splines, does not do telescopic movement,  so the service life of the equipment is prolonged and the rigidity is strong.

6. Data query: The system has the function of historical data record query. You can query the processing quantity on duty and cumulative processing quantity, and also make statistics counting on the cumulative operation records of the machine too.
