High efficiency deep hole honing machine 2M2135

Range of honing dia.: 80-350mm Max. honing depth: 8000mm Dia. range for workpiece clamping: 100-420mm Center height: 350m

Overview

This machine is a special equipment used for honing cylindrical deep hole parts such as various hydraulic oil cylinders and cylinders .Hole diameter accuracy of machined workpieces can be up to or over IT7 and surface roughness Ra0.2-0.4μm.lt can also repair and maintain taper and elasticity of machined workpieces with the help or 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 labor.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 deep hole parts after rough-boring. it can directly perform high efficiency honing of cold drawing steel pipes. Traditional deep hole processing is simplified by using this machine. Productivity is greatly increased. 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 perfect equipment for machining deep hole parts.
