A kind of new ceramic wood cutter
Technical field
This utility model is related to timber and composite wooden material machining field, is particularly applied to the one of wood cutting
Plant new ceramic wood cutter.
Background technology
It is known that sintex has been widely used for metal cutting, its plurality of advantages is mainly manifested in: 1. Stupalox
There is very high hardness and wearability, its room temperature hardness reaches 91-95hra, exceedes hard alloy;2. Stupalox have very high
Thermostability, at 1200 DEG C, hardness is 80hra, intensity, toughness reduce less so as to can be than the cutting of high 2-10 times of hard alloy
Speed carries out machining;3. there is high chemical stability, still have preferable antioxidation, anti-stick property at high temperature;4. have
Relatively low coefficient of friction, coefficient of friction during ceramic tools in cutting processing is less than carbide tool;5. ceramic cutting tool material
Density is only equivalent to a quarter of sintered carbide tool material, can improve the cutting speed (rotating speed) of cutter further;⑥
Sintex is cheap, abundant raw material.Above advantage also for sintex be applied to wood cutting manufacture field provide all
Many advantages.
Compared to metal, timber is the extract of high anisotropy and uneven natural composite material, wood internal
The finishing material of the adhesive within matter, composite wooden material or outside and higher cutting speed, sintex is in cutting wood
During material, especially in upmilling process, cutting force is dynamic cutting force, and cutting force can be with the change of cutting-edge
Change, dynamic cutting force cans be compared to the cutting edge that the shock loading changing equally acts on sintex, easily causes cutter tipping and breaks
Damage.Therefore it is considered that sintex is not suitable for being applied to the machining of timber and composite wooden material.
