Product Description Application of machine This machine is a special equipment used for honing cylindrical deephole parts such as various hydraulic oil cylinders and cylinders. M. It can also repair and Hole diameter accuracy of machined workpieces can be up to or over IT7 and surface roughness Ra0.2-0.4 maintain taper and ellipticity of machined workpieces with the hepl of partial honing. Auto-cycle timing control unit is used on this machine during reciprocating honing so as to assure accuracy of machined holes and decrease the intensity of labour. Sand blades and workpieces always maintain constant pressure during honing. It is a feature of high efficiency and strong cutting force. It can perform rough and finished honing of general cylindrical deephole parts after rough-boring. It can directly perform high efficiency honing of cold-drawing steel pipes. Traditional deephole processing is simplified by using this machine. Productivity is greatly in creased. Materials of honed workpieces may be casting iron or all kinds of steel including quench parts. Cooling system of this machine adopts the method of three-step filtering in order to assure clearing of coolant. This machine is controlled by electrical operating center. It is easy, safe and reliable in operation. It can perform not only honing of mass products but also small batch workpieces. It is a perfect equipment for maching deep hole parts.SPECIFICATION 17603 17604 2M2125 2M2135 Range of honing dia. 40-250mm 80-350mm Max. honing depth 12000mm 12000mm Dia. range for workpiece clamping 50-350mm 100-420mm Center height 350mm 350mm Speed range of headstock spindle 25-400rpm 15-240rpm Reciprocating speed of honing box 5-25m/min 5-25m/min Speed of workpiece (constant) - 10r/min Flow of reciprocating hydraulic system 100L/min 100L/min Max. working pressure of reciprocating hydraulic system 5MPa 6.3MPa Flow of honing head expanding system 12.5L/min 12.5L/min Max. pressure of honing head expanding system 6MPa 6MPa Volume of hydraulic system 200L 560L Flow of coolant pump 100L/min 200L/min Volume of coolant tank 950L 1200L Capacity of refrigeration - 12000kcaph Motor power of honing box 11kw 15kw Motor power of workpiece rotating - 4kw Motor power of reciprocating system 11kw 11kw Motor power of honing head expanding system 1.1kw 1.5kw Motor power of refrigeration pump 0.25kw 0.45kw Motor power of refrigeration set - 3.7kw
