Advantages and necessity

Technical parameters

1

CNC hardening machine tool

1. Horizontal structure, easy to install and dismantle

2. Lead screw, high precision

3. Work stable, long service life

1.Work piece rotation speed :0-400r/min

2.Control precision: 0.01mm

3.Walking speed: 0-6m/min

2

Intelligent control center

1. Using a central microprocessor and PLC centralized control
2. The high degree of automation, enabling a key operation is completed
3. Centralized control, easy to operate, not easy mistakes, product qualification rate is high

can preset up to 100 procedures, process programming and store is more scientific

IRclosed-looptemperature control system

1. Use temperature control system work (speed, power, etc.), avoiding the temperature difference between the actual and the desired temperature caused by the voltage fluctuations, human factors, the intensity of light. Ensure consistency of the heating temperature, thus ensuring absolutely consistent product quality;
2. Control of high accuracy, up to +/- 10C

1.Measurement range:300-1300C

2.Measurement accuracy:+/-5C

3.Repeat accuracy:+/-0.5C

4.Responding time 10ms(95%) 

5.Aim:Laser aiming(2 grade laser, Max. output power 1MW,650nm)

Special igbt induction heating power supply

1. Saving 50% energy than the tube, 20% than the SCR. Processing one ton steel consumption is not higher than 300KW/H
2. Small size, easy to move, no million-volt risk, no radiation, no harm to the operator

3. Hardened layer can be controlled, proper depth, high rate of qualified products, completely solve the tube equipment shallow hardening layer , pipes life is short; solve the SCR equipment deeper hardening layer, easy explosive pipe ,rejection rate and other issues 4. equipment reliability, stability

1.Input voltage:3 phase, 380V+/-10%,50-60HZ

2.Oscillation frequency:20-40KHZ 3.Oscillation frequency auto tracking, adapt to load. Power factor reach up to above 95%.

4.The machine has water shortage, lack of phase, over voltage, over current etc, automatic protect device

5

Closed cyclecooling equipment

1. The corrosion-resistant, closed cooling, high precision temperature control
2. eliminate scale and impurities harm
3. less water, small mounting space
4. constant quenching medium temperature
5. constant quenching medium flow and pressure, quenching high consistency

1.Cooling capacity:180600kca/h

2.Working pressure:0.25MPA

3.

Include cooling equipment and quenching medium two sets system

6

Special sensor support frame

1. coaxial design, the lowest loss
2. Multi-point support, no deformation, long life
3. quick connector, easy to operate
4. Special copper tube, with high mechanical properties and electrical properties

Length 4m

7

Sensor /induction coils

1. The special production, while heating spraying water, deformation amount is very small 2.Easy to replace, low cost
