Working process of vacuum furnace

Use a flux with a melting point lower than the connected workpieces, place it in a high vacuum chamber, and use infrared radiation to heat the workpiece and flux till temperature over the melting point of the flux. So that the flux becomes liquid with sufficient fluidity. Because of the capillary action, the flux will infiltrate over the surface between workpieces and joint the two workpieces after cooling down.

Advantages of vacuum furnace

※Easy to operate

※Do not require experience

※Lower the impact from manpower

※Quality remains stable

※Suit for PCD, MCD, CVD, Ceramic, CBN…materials

※Uniformly heated

※Avoid damages from pollution

※Clean and neat workpieces

※Automation

Features of vacuum furnace

High-quality brazed joins

Less distortion during brazing process will result in less the weariness of the cutter blade and cost down. Our sensors detect the presence of the abnormal condition and power failure. All the information from the sensors will be sent and integrated into the information system

Time saving

The whole process time for a finished working piece only takes about 30 min.

Easy-to-use operation

Automated process with simplified interface served with push button operation only.

Multi-functions

MoreSuperhard Vacuum Brazing Furnace can be used for wide range of tooling materials and it will reduce the deformation of the finished products. Tool materials can be placed in vertical, horizontal or oblique angle during the brazing process

    Applications of PCBN tools

    Because of PCBN has high hardness and wear resistance, do not react with iron group metals at high temperature of chemical inertness, so it is mainly used for high hardness material and machining of difficult-to-machine materials, such as hardened steel, high alloy wear resistant cast iron, high temperature alloy, high speed steel, surface spray welding materials, sintered metal materials machining difficult-to-machine materials.

    Advantages of processing aluminum with PCD tool

    How to select PCD tool? Generally speaking, the larger the PCD size, the stronger the tool wear resistance. Usually finishing or super finishing, the selection of fine particle PCD, and coarse particle PCD tool selection. Tool manufacturers often recommend the use of fine particle PCD grades for silicon-free and low-silicon aluminum alloys and the use of coarse-particle PCD grades for high-silicon aluminum alloys for the same reason. PCD tool processing surface quality in addition to see the granularity of the tool, also mainly depends on the quality of the cutting edge of the tool, so the quality of PCD tool must be better. PCD cutting edge common processing methods generally have two kinds, one is through the way of slow-feeding wire cutting processing, this way of processing cost is low, but the quality of the edge is general. And the other is through laser to rough machining, the cost is slightly higher, but the quality of the edge is much better than slow-feeding wire cutting processing. There is another is to use laser rough machining and then grinding to finish, the edge quality is best.
