Processing center for compressed air demand through a number of core links, granklin water lubricated screw air compressor with oil-free clean air supply and stable pressure output characteristics, can provide efficient and reliable gas source support.
Tool cooling and chip removal system
When the machining center is cutting metal, the friction between the tool and the workpiece produces high temperature. It is necessary to spray the coolant to the cutting area through compressed air, and blow away the chips to avoid secondary cutting. If the compressed air contains oil or impurities, it may lead to emulsification failure of the coolant, or chip adhesion on the surface of the tool, affecting the machining accuracy and tool life. For example, in aluminum alloy processing, oil contamination may cause chips to stick, causing scratches on the surface of the workpiece.
Pneumatic Spindle and Fixture Control
Pneumatic spindles are often used in high-speed machining centers to drive the spindle to rotate or tighten the tool by compressed air. At the same time, the pneumatic fixture uses compressed air to realize the rapid clamping and positioning of the workpiece. If the compressed air pressure is unstable or contains oil, it may cause the spindle speed fluctuation or the fixture clamping force is insufficient, causing the workpiece to vibrate or loosen, which directly affects the processing quality. For example, in precision mold processing, fixture looseness may lead to cavity size deviation.
Automatic tool changer (ATC)
The automatic tool changer system of the machining center relies on compressed air to drive the rotation of the tool magazine, the tightening of the tool and the action of the manipulator. If the compressed air contains oil, it may contaminate the tool magazine guide rail or manipulator cylinder, resulting in stuck tool change or inaccurate positioning. For example, an auto parts processing plant had a 30% extension of tool change time due to oil in compressed air, resulting in a significant drop in production efficiency.
Protective door and chip conveyor control
Pneumatic control is often used for auxiliary equipment such as protective door and chip conveyor in the machining center. Compressed air is required to drive the cylinder to realize the opening and closing of the protective door or the reciprocating movement of the chip conveyor. If the compressed air quality is poor, it may cause the cylinder seal aging, causing air leakage or malfunction. For example, failure to fully close the guard door may cause chips to splash into the operating area, posing a safety hazard.
Oil-free clean gas supply ensures processing quality
Granklin air compressor adopts a single screw plus star wheel structure to replace lubricating oil with water to realize cooling and sealing in the compression process, thus eliminating the risk of oil pollution from the source. The output of the compressed air oil content is zero, can avoid the oil pollution coolant or chip, to ensure that the tool cooling effect and chip fluency. For example, in titanium alloy processing, oil-free air can prevent chip adhesion and improve the surface roughness of the workpiece.
Stable pressure output supports precision machining
. Granklin air compressor can output common pressure of 0.3-4.0MPa through single-stage or two-stage compression configuration, covering the whole process requirements of the machining center. Its dynamic pressure regulation system ensures pressure fluctuations of less than ± 0.05MPa, meeting the pressure stability requirements for precision machining. For example, in the processing of optical components, stable air pressure can avoid workpiece vibration and ensure processing accuracy.
Low maintenance cost and long-life
oil-free design eliminates the need for oil removal filters, activated carbon filters and other post-processing equipment, reducing equipment investment and maintenance costs. At the same time, the water lubrication technology avoids the frequent replacement of the adsorbent caused by oil pollution and prolongs the service life of the equipment. For example, after using Granklin air compressor in an aviation parts processing plant, the annual maintenance cost is reduced by about 25%, and the equipment failure rate is reduced by 40%.
High-speed machining center
high-speed machining center for air pressure stability requirements are extremely high. Granklin air compressor can be equipped with air storage tank and precision filter to provide stable air pressure of 0.6-0.8MPa to meet the needs of pneumatic spindle and automatic tool changer. For example, in a 5-axis machining center, its stable air pressure ensures that the spindle speed fluctuates less than ± 10rpm, improving the quality of the machined surface.
Heavy cutting machining center
requires high-pressure air to strengthen the cooling effect. Granklin air compressor provides high-pressure air of 1.0-4.0MPa through two-stage compression technology, while ensuring oil-free cleanliness and avoiding oil pollution of coolant. For example, in the processing of large castings, high-pressure oil-free air can quickly blow away chips and reduce tool wear.
Clean workshop machining center
clean workshop of electronic, medical and other industries requires high cleanliness of compressed air. Granklin air compressor can be equipped with high-efficiency filter to provide compressed air with cleanliness up to ISO 8573-1:2010 Class 0 to meet the environmental control requirements of clean workshop. For example, in semiconductor processing, oil-free air can prevent oil from contaminating the wafer surface and improve product yield.
the new processing center
is recommended to use granklin single-stage compressed water lubricated screw air compressor, equipped with air storage tank and freeze dryer to meet the main process requirements of 0.6-0.8MPa. For example, in an automotive engine block processing line, such a configuration can stably support core links such as tool cooling and automatic tool change, while reducing overall energy consumption.
for the existing processing center transformation
, it is recommended to install a degreasing filter or activated carbon degreaser at the front end of the suction dryer to control the oil content of the intake air at 0.01 mg/m & sup3; Below. However, it should be noted that such equipment requires regular replacement of the filter element and does not completely eliminate the risk of oil contamination. In the long run, upgrading to Granklin oil-free air compressor is a better choice.
Air compressors are widely used in many industries. The following are several major industries where air compressors are used more: Equipment manufacturing industry: Air compressors provide power source for equipment manufacturing industry and are used to drive pneumatic tools, robots, conveying systems, etc.
The interior of the cold dryer is usually equipped with pre and post filters to intercept impurities and oil in the compressed air. If the filter is clogged, the airflow resistance increases significantly, resulting in a decrease in downstream pressure. For example, in the pharmaceutical or electronics industry, the cleanliness of compressed air is extremely high, and the filter needs to be replaced or cleaned frequently, otherwise the blockage will directly cause the outlet pressure to drop.
To judge whether the end of the air compressor is using gas, it is necessary to conduct a comprehensive analysis in combination with the equipment operating state, pressure change, sound and vibration, energy consumption data and professional testing tools. The following is the specific judgment method and steps: 1. observe the air compressor running state loading and unloading
