China 2mk2125 Deep Hole Honing Machine

2MK2125
2MK2125 CNC high efficiency deephole honing machine is an equipment suitable for honing and burnishing cylindrical deephole parts such as various cylinders. This machine is specially for honing and burnishing step holes, and the hole diameter accuracy of machined workpiece can be up to and over IT7~IT8,and the surface roughness reach Ra 0.2~0.4 µm. It can also repair and maintain taper and ellipticity of machined workpiece with the help of partial honing. It can directly perform high efficiency honing of cold drawing steel pipes.2MK2125 is an ideal equipment for deephole machining with high accuracy and high efficiency.
This machine is mated with SIEMENS or other CNC system, AC servo motor, travel headstock with rotating honing bar adopts stepless spindle speed. It is mated with Germany ATLANDA high accuracy racks and gears to realize the reciprocating of honing head and it can control the honing position too. This machine is mated with double linear guide way,so it has long service life and high accuracy. The honing head adopt hydraulic constant pressure expanding,sand blades always maintain constant pressure to be sure the roundness and cylinder of the workpiece.The honing pressure can be adjusted according to requires and it is device high and low pressure control to realize the rough and finish honing on the operate station.The machine's other equipments such as hydraulic valve, automatic lubricate station are use the well-known brand products. Otherwise, the CNC system, linear guide way and hydraulic valve can be chosen by customer.
