What is the principle of nitrogen counterweight for machine tools?

You're probably talking about machining center balancing cylinders.

How much nitrogen is flushed by the accumulator on the oil circuit? The pressure of different machine tools and accumulators is different. It is necessary to punch according to the instructions for the use of the machine tool, otherwise the correct work of the machine tool cannot be guaranteed and the machine tool will be damaged!

The counterweight nitrogen balancing system of the machining center comprises a nitrogen cylinder, a control system and a balance cylinder, the nitrogen cylinder is located on one side of the column, the top of the column is provided with a balance cylinder, the nitrogen cylinder is provided with a control system, and the control system is connected with the balance cylinder through a trachea. The utility model discloses.

The beneficial effects are: changing the traditional counterweight and chain type to a nitrogen balance cylinder system; Using the accumulator principle, the balance cylinder is controlled to cooperate with the servo motor in the headstock.

Rising or falling, it can also balance the weight of the headstock to achieve high-speed and high-precision machining; No need for external power equipment, saving energy; The counterweight nitrogen balance system of the machining center can adapt to the rapid balance lifting and lowering at high speed, without noise, and can make accuracy and surface roughness during the machining process.

Significant lifting, minus micro-vibration, and extended screw and motor life.

Very simple! It is because the temperature is high, the solubility of the substance will increase (tolerance), and after the temperature drops, the tolerance will be lower, and too many substances will not be dissolved, and it will be precipitated You add a little more runny acid, and it's OK! Your problem is that the runny acid is a little less.

We must first understand the role of CNC machining center configuration: the main thing is to reduce the load of the motor and screw, inhibit the heating of the motor and screw, so as to ensure the machining accuracy and prolong the life of the motor and screw.

1.Counterweight iron counterweight.

The counterweight and chain structure are designed, the failure rate is low, and the weight of the counterweight iron is used to offset the weight of the spindle unit, so as to improve the rapid traverse speed of the machine tool, reduce the load on the lead screw and reduce the motor load.

2.Nitrogen cylinder counterweight.

The nitrogen counterweight balance system of CNC machining center comprises a nitrogen cylinder, a control system and a balance cylinder, the nitrogen cylinder is located on one side of the column, the top of the column is provided with a balance cylinder, the nitrogen cylinder is provided with a control system, and the control system is connected with the balance cylinder through the air pipe. Using the accumulator principle, the balance cylinder is controlled to rise or fall with the servo motor in the headstock, and the weight of the headstock can also be balanced to achieve high-speed and high-precision machining; No need for external power equipment, saving energy; The counterweight nitrogen balance system of the machining center can adapt to the rapid balance lifting and descent at high speed, without noise, which can greatly improve the accuracy and surface roughness during the machining process, reduce micro-vibration, and prolong the service life of the screw and motor.

Generally, we commonly use small machining centers, vertical machining centers with counterweight iron counterweight.

Recommend a document to help you have a more comprehensive understanding of CNC machining centers.

The Z-axis counterweight of the machining center has a high accuracy, and now it is generally used with nitrogen counterweight, and in the past iron blocks were used.

Machining center (abbreviated as CNC in English, full name is computerized numerical control): it is a highly automated multi-functional CNC machine with a tool magazine and automatic tool change device. In Hong Kong, Taiwan and Guangdong, many people also call it a computer gong.

After the workpiece is clamped once on the machining center, the digital control system can control the machine tool to automatically select and replace the tool according to different processes, automatically change the spindle speed, feed and movement trajectory of the tool relative to the workpiece and other auxiliary functions, and complete the processing of multiple processes on several surfaces of the workpiece in turn. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.

In fact, they are CNC machine tools, there is no concept of engraving machine abroad, and the processing of molds is mainly based on machining centers (computer gongs) milling, but it is subdivided in China. The accuracy depends on what kind of workpiece the equipment processes and whether the workpiece is suitable for the equipment to process. Machining centers are mainly milling, but machining centers.

The tool holder is clamping or clearance, and the numerical control is considered to be the loss of pressure of the balance cylinder.

It is estimated that it is a problem with the lifting shaft motor holding the brake: the holding brake does not work, and it may be due to the failure of the driver or servo motor.

Nitrogen counterweight depends on the value of the lower pressure gauge.

In the case of mechanical counterweight, there is a gap in the track, and the plug bar can be tightened.

If it is a motor with brake control, it is a brake problem to check.

1. Motor braking.

2. Counterweight, such as nitrogen, hydraulic, mechanical counterweight.

3. The coupling is self-locking.

Generally, the motor comes with its own brake.
