PCD PCBN CBN CVD diamond tools vacuum brazing furnace

Chamber size

200X400mm(dia x height)

Max temperature

1200C

Max working temperature

1100C

Temperature controlling

• PLC full-automatic control, also can be operated by workers.
• PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor.
• 50 programmable segments for precise control of heating rate, cooling rate and dwell time.
• Built in PID Auto-Tune function with overheating & broken thermocouple broken protection.
• Over temperature protection and alarm allows for operation without attendant.

Max vacuum

7x10-4Pa

Temperature accuracy

±1C

Temperature Uniformity

±5C over 1200mm

±3C over 800mm

Heating rate

0-20C /min

Heating element

• High quality Fe-Cr-Al-Mo resistance wire, long working lifetime, 3 to 5 years.
• There is heating element on chamber side and bottom,more uniform thermal field,longer uniform heating zone.
• heating zone height is 400mm, which is much longer than normal type(150-200mm).

Furnace chamber

• Cylinder-shaped furnace chamber.
• Two layers of high quality Alumina ceramic fiber as insulation.
• There is quartz tube in the chamber, which can make sure the workpiece to be clean, no need to cleaning.
• There is water cooling set on the outside of the chamber,more cooling rate
• Chamber is formed by two semicircle, opening at the middle freely, which can make the furnace cooling fast when the temperature is lower than 300C.

Observation well

Specially designed observation well, by which can observe brazing effect at high temperature directly, then it is helpful to improve technology.

Available solder

Ag, Cu, Ni, Ti, etc.

Rated power

10KW

Material platform

• 310S high temperature stainless steel.
• Designed with neck,hang type, NO.of material platform can be adjusted according to workpiece quantity.
• Material plat form up and down rate is adjustable.

Vacuum system

• All the vacuum valves are electromagnetism-air-operated type, which make the furnace to be automatic.
  
  
•  Our furnace adopts China best vacuum pump brand products - Chengdu Nanguang. All vacuum valves are made in Ningbo factories:Mechanical pump +diffusion pump+ digital vacuum gauge. Diffusion pump is 150 type,high quality and long working lifetime, low repairing cost( normal brazing furnace uses molecular pump, which is very easy to break, and high reqairing cost),Mechanical pump is VRD-16, direct-connected type.
  
  
• Max vacuum 7x10-4Pa, brazing vacuum 7x10-3Pa
