Abstract
The present invention relates to a binder of artificial diamound saw blade cutter head for cutting hard granite. It is characterized by adopting cobalt-free binder so as to greatly reduce binder cost, and its production process is simple, easy to operate and its product performance is excellent.
Description
The present invention relates to a kind of artificial diamond saw blade binder, particularly relate to the bond that is used to cut hard granite synthetic diamond saw blade cutter head.
In the present prior art, the bond that is used to cut hard granite synthetic diamond saw blade cutter head is a cobalt base bonding agent, though such bond can reach basic demand on performance, but cost height, the production technology strictness, not easy to operate, product is in more weak status in market competition.
The invention provides a kind of function admirable, production technology is simple, bond with low cost.Its cost only accounts for existing with about 20 percent of bond, has strengthened the capacity of competition in market.
Diamond disc is made up of a steel matrix and sawtooth (being cutter head) two parts of welding on its periphery.Matrix is a supporting gulleting (being cutter head), is again simultaneously to connect cutting equipment, realizes the rigid element of cutting operation.Diamond sawtooth is that cutter head is the workpiece of saw blade, and after matrix was determined, the performance of cutter head became the decisive factor of saw blade serviceability, and the operating characteristic of cutter head is by the character decision of diamond and bond.After common adamantine grade and granularity and the concentration decision, a crucial factor is exactly the character of bond.This bond composition is by weight percentage: bronze powder (663) 45-55, fe-based alloy powder 15-25, tungsten carbide (WC) 10-20, chromium powder (Cr) 5-15, zinc powder (Zn) 3-7.Above metal dust should reduce before use, remove the oxide on powder top layer, the reduction back fully mixes in this ratio, compound will grind in wet milk or ball mill, and add a certain amount of alcohol or other organic solvents as medium, the serviceability temperature of this bond is a 700-800 degree Celsius, is applicable to that diameter is the saw blade of 1600mm.
Usually the bond of the synthetic diamond saw blade cutter head of the hard granite of cutting is cobalt (Co) based anchoring agent, and cobalt is a rare metal, costs an arm and a leg.This bond adopts no cobalt (Co) bond, and has adopted fe-based alloy powder that the bond cost is significantly reduced, and production technology is simple, and properties of product improve.Its characteristic: (1) has good operational characteristic is briquettability and mouldability, produces high-quality product easily.(2) good adhesive property, diamond there is good wellability, behind the sintering securely bond diamond be beneficial to have high intensity after diamond is given full play to dissection (3) bond sintering, fabulous approaching of the suitable hardness and the linear expansivity of matrix, cutting efficiency and cutting quantity are taken into account, remained on the reasonable levels.
Following examples have illustrated the present invention.
Embodiment: this bond composition is by weight percentage: bronze powder (663) 50, fe-based alloy powder 20, tungsten carbide (WC) 15, chromium powder (Cr) 10, zinc powder (Zn) 5.
Realize that this product may further comprise the steps:
1. above powder reduces respectively.
Fully mix in proportion after 2 reduction, and add an amount of alcohol and other organic solvents.
3 sintering temperatures are 700-800 degree Celsius.
Claims (3)
1. bond that is used to cut hard granite synthetic diamond saw blade cutter head, it is characterized by: composition is by weight percentage: bronze powder (663) 45-55, fe-based alloy powder 5-15, tungsten carbide (WC) 10-20, chromium (Cr) 5-15, zinc powder (Zn) 3-7.
2. bond as claimed in claim 1 is characterized in that having adopted fe-based alloy powder.
3. bond as claimed in claim 1 is characterized in that the bond that cuts hard granite synthetic diamond saw blade cutter head has adopted no cobalt (Co) bond.
