2MK2135x8m CNC High Efficiency Deep Hole Honing Machine Range of honing diameter:80-350mm, Max. honing depth:8000mm - details see: https://www.machineto.com/2mk2135x8m-cnc-high-efficiency-deep-hole-honing-machine-10127614

1. Features

• 2MK2135 CNC high efficiency deep hole honing machine is equipment suitable for honing and burnishing cylindrical deep hole parts such as various hydraulic oil cylinders and cylinders. This machine is specially for honing and burnishing step holes and the hole diameter accuracy of machined work piece can be up to or over IT8-IT9, and surface roughness Ra 02.-0.4µm.It can also repair and maintain taper and elasticity of machined work piece with the help of partial honing. It can directly perform high efficiency honing of cold drawing steel pipes.
• 2MK2135 deep hole honing machine is ideal equipment for deep hole machining with high accuracy and high efficiency. This machine is mated with SIEMENS or FANUC CNC system. AC servo motor, honing box adopt step less speed, and it also mated with Germany ATLANTA 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 linear guide way and it have 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 work piece. 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.
