Why cylindrical grinding has become the new favorite of the industry?

Machining with a cylindrical grinder is to form the required external cylindrical surface or conical surface on the surface of the workpiece. Machining of cylindrical grinder is realized by grinding with grinding wheel. Machining with a cylindrical grinder can not only form the outer cylindrical surface and conical surface of the workpiece, but also grind the inner hole and step surface. Machining excircle grinding parts and grinding parts with high precision and flatness, such as shafts, sleeves and ring gauges, this machine tool is suitable for machining the above precision parts in single piece or small batch.

Structural features: a. The longitudinal movement of the machine tool table and the rapid advance and retreat of the grinding wheel stand are controlled by hydraulic pressure, and the workpiece rotation is driven by DC motor, which can be stepless speed regulation within the speed range. B. The lubricating oil pump, cooling pump and grinding wheel stand of the spindle bearing of the grinding wheel stand are driven by separate motors.

150kg main technical specifications: main specifications, maximum grinding diameter × maximum grinding length (outer circle/inner circle) φ320× 1000, 1500 /φ 125×220mm.

The center height of the machining range is180mm, the center spacing is1000mm, and the diameter of the grindable excircle is1500mm. Minimum φ8mm and maximum φ60mm need not be centered.

Minimum φ8mm and maximum φ320mm grindable inner diameter: minimum φ30mm and maximum φ 125mm can be clamped by the center frame, while minimum φ 16mm and maximum φ 125mm can not be clamped by the center frame.

The maximum workpiece weight is 150kg.

The machining of cylindrical grinding machine tool plays an important role in modern industry, and the machining technology of cylindrical grinding machine tool is constantly improving in order to meet the needs of industrial production in time.

The cutting motion of grinding wheel can be divided into main motion and feed motion, and the feed motion can be divided into three types: circumferential feed motion of workpiece, longitudinal feed motion of cylindrical grinder table and transverse feed motion of grinding wheel frame.

Machining and grinding of cylindrical grinder machine tools are mainly divided into longitudinal grinding method and cut-in grinding method. Cylindrical grinder can be divided into ordinary cylindrical grinder, universal cylindrical grinder, wide grinding wheel centerless cylindrical grinder and end-face cylindrical grinder.

Grinding machine tools, etc. Their working principles are basically the same, but their performance and structural rigidity are different. The cylindrical grinding machine tool drives the grinding wheel to rotate at a certain speed through the transmission system to grind the surface of the workpiece and form the required shape.

Matters needing attention in the design of machining system of cylindrical grinder

The accuracy of grinding wheel balance should be improved: the motor should run at rated speed, and in order to reduce the vibration at high speed, the dynamic balance between motor rotor and grinding wheel should be improved and corrected. External grinder powered by sand

The frequency conversion speed regulation technology is introduced into the main motor of the grinding wheel to meet the needs of various shaft excircle grinding, improve work efficiency, improve the grinding quality of shaft excircle and save energy. Combined with the actual field application, the operation was carried out.

The reaction is more handy, the surface is smooth and the imaging is high, and the yield is greatly improved. Low-speed heat dissipation: Because the motor is cooled by self-cooling fan, the heat dissipation condition becomes worse at low speed and the load torque is larger, so the motor

The temperature will rise, so the setting of the minimum speed is based on the premise that the surface temperature difference of the motor does not exceed the allowable value.

Because the output of frequency converter contains higher harmonics in the process of frequency conversion and speed regulation, electromagnetic noise will be produced in the motor. Therefore, a zero-phase noise filter should be installed at the output to reduce the auxiliary radiation interference and induced noise.
