Halnn CBN Tools Processing Slewing Bearing with BN-S20 Solid CBN insert
Requirements of cutting Tool for hard turning Bearings for wind turbines
The working allowance of Hard turning Bearings for wind turbines after heat treatment is based on the previous heat treatment process and the reserved quenching deformation. Usually the working allowance of the Bearings for wind turbines after hardening will be 2~6mm; Hard turning insert in the large margin machining quenching need excellent roughness. So bearing industry for wind turbines complained about the poor processing finish which caused by low hardness of the cubic boron nitride blade, or the blade is too brittle easy to collapse the knife, especially the intermittent surface.
As a kind of non-metal based CBN cutting tool, BN-S20 use non-metallic adhesive. BN-S20 CBN inserts not only ensure the toughness of cubic boron nitride tool at the same time, avoid the metal bond by adding the CBN tool after heating caused by premature softening of the metal binder blade reduced life, BN-S20 is suitable for large quenching after high Hardness of the workpiece in the high - speed rough fine cars, the hardness of HRC98.5; Machinable hardness after heat treatment: HRC45-HRC79. Suitable for a long time large margin hard turning or car on behalf of the mill.
The feasibility of hard turning instead of grinding process in the wind turntable bearing industry and the use of new grades CBN cutting tool application case: BN-S20 brand CBN blade processing wind power bearing rings
The finishing working allowance after quenching will be 5mm; linear speed 90-150m/min after finishing roughness of the channel surface roughness Ra0.3μm, to meet the requirements of hard turning instead of grinding process; Bottom beating all<0.005mm, from the processing efficiency and cost considerations, turning instead of grinding process has better advantages.
For example, Hard turning bearings rings for wind turbines (Diameter: φ1900mm, thickness 130mm)if after quenching all the working allowance use turning instead of grinding process grinding, , grinding time is 18 hours or more, with turning instead of grinding, the working efficiency will be about 4 times of grinding process with only 4.5 hours. With the same precision machining requirements, the use turning process working efficiency is 4 times the grinding process; From the tool durability, BN-S20 brand cubic boron nitride blade turning 1900 wind power pulping bearing rings, for example, can be fine finish turning more than 30 piece rings; the consumption of electricity and labor, materials costs only is 20 percent of grinding; tool durability, the use of lower cost.
For the grinding process, it can avoid grinding burn when compared with grinding. Moreover, the large-scale bearing can choose dry cutting method, which is economic and environmental protection. Compared with the grinding process, Hard turning down the iron filings can be very convenient to deal with, as a resource recycling and low cost, reduce environmental pollution.
It is not only suitable for large diameter slewing bearing and wind power turntable, but also suitable for large diameter rotary bearing and large-diameter rotary bearing. It is widely used in the machining of the inner and outer ring parts of cubic boron nitride blade material grade BN-S20; Bearings, but also for non-standard bearings to the car on behalf of the mill, the following diameter 500mm overall hardness of HRC60 above the bearing ring bearing a large margin to replace the rough grinding process; for machining allowance after quenching is less than 0.3mm small size bearing rings Can choose BN-H20 brand cubic boron nitride.
It should be noted that after hardening the bearing ring hard turning allowance or intermittent processing of the blade edge to be processed 0.2*20 degrees negative chamfering, and supporting the design of the holder arbor negative rake angle 6-7 Degree is better; small margin of heat after finishing the blade edge of the blade generally take 0.1mm negative chamfering; blade tip radius of the arc according to the bearing ring car processing tooling fixture used to select to ensure that the whole car on behalf of the grinding process The process does not vibration knife, not to knife.
