装配式切槽刀(苏联发明证书№3721771),用于重型车床或特型车床上以大切削用量进行加工;它与常用的车刀相比,刀片夹固更加可靠。车刀装配时,把刀片5、支承片3、压板9和螺母2装在刀杆1内,并须使螺毋的弹性突部4进入刀片5的槽6和刀杆1的凹槽10内。螺母的支承点位于离螺纹孔c和d的部位。在拧紧螺钉8时,压板9通过支承片3把刀片5压向刀杆1。同时,与销钉7接触的螺母突部的槽被松开;刀片槽6和刀杆凹槽10两
Assembled grooving knife (Soviet invention certificate № 3721771), for heavy duty lathes or special lathes with a large amount of cutting processing; it is more commonly used lathe blade clamping more reliable.
