Main applications and characteristics: SP-25  series are  suitable for the heating of small metal parts, for example, (1)brazing of machining tools (2)Brazing of diamond tools (3)Heat treatment of small parts (4)Melting of gold, silver, copper, brass of little amount (5)Melting of steel and stainless steel of little amount. SP-25  series machines are characterized with simple structure, high reliability and low price, and are one of the most popular models and have been used widely in every areas of metal heating.
Working theory and structure In SP-25  series machines, series oscillating circuit is applied as circuit below, through high frequency transformer, low voltage and high current power is output to go through the induction coil. SP-15 series machines are the first models developed in our company, SP-25 uses IGBT components , use our first generation inverting control technology, the machines are featured with simple structure, high reliability and low price, and they are easy to use and to repair, and are now the most widely used machines both in China and abroad.Â
Advantages  of Timer function of SP-25A with timer:
Heating power, retaining power, heating time, retaining time and cooling time can be preset and adjusted, this makes it possible to control the heating curve and heating time.
It is suitable to use in the repeated heating or high speed heating of small parts;
When using in brazing, with proper timing parameters, rapid heating and retaining can be achieved to keep the temperature while the brazing material is melted and then to let the brazing material spread smoothly to form good joint.Â
Advantages of separated transformer of SP-25B Split type with separated transformer:
In SP-25B Â machines, the high frequency transformer is separated from the generator, with 2 meters connecting cable at least.
It is suitable to use in the dirty or corrosive surroundings, the generator can be put in a clean space to increase the reliability.
With the small size and light weight of the separated transformer, it is convenient to use in the production line and easily assembled inside the machinery or moved mechanism.
Titanium alloys are widely used in aerospace, navigation, marine projects, medical and other industries due to their high strength, good corrosion resistance and high heat resistance. And titanium Precision Machining Parts are also widely used as part of titanium alloy parts, and it is on the rise. At present, the most used titanium alloys in the CNC machining industry should be titanium turning parts, such as titanium needles used in medical equipment, non-standard titanium shafts commonly used in marine projects, and non-standard titanium screws commonly used in many industries are all titanium turning parts Components. Of course, there are also many titanium alloy milling parts or titanium alloy turning composite parts used in all walks of life.
SCZY has been processing titanium alloy and molybdenum alloy parts for five years, and we have a relatively comprehensive grasp of material properties and processing technology. Our titanium alloy precision machining parts and molybdenum alloy precision machining parts have been exported to Sri Lanka, Germany, Italy and other countries for a long time.
