On September 10, from CSR Qishuyan Locomotive & Rolling Vehicle Technology Research Institute Co., Ltd. (hereafter referred to as Qi Research Institute), it was learned that the company's employee Liu Yunqing's successfully developed CNC Honing Machine attracted widespread attention from the society and won the top ten in Changzhou City. The first prize for employees' scientific and technological innovation achievements. PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.

CNC Honing Machine is a key process equipment in the field of precision boring hole processing for auto parts, hydraulic valve bodies, air conditioners, refrigerator compressors and bearing manufacturing, and has a wide range of application requirements. Compared with similar imported equipment, the CNC grinding machine developed by Qi Yan has a manufacturing cost that is only 1/4 of that of imported equipment. Each unit can save more than 1.5 million yuan in procurement costs. In terms of machining accuracy, the CNC honing machine can process precision. Accurate to 0.003mm, far exceeding the 0.01mm machining accuracy of similar imported equipment, at the same time, the single product processing speed increased from 1 minute to 27 seconds, which greatly improved the work efficiency.
Since the company was put into use, the equipment can process 400,000 automotive parts and intermediate products annually, and has generated more than 40 million yuan in economic benefits.
