Hones, CNC Deep Hole Honing Machine 2mk2125/2mk2135/2mk2150 Series With Iron Casting Bed

Short Description:

2MK2125, 2MK2135 and 2MK2150 series CNC deep hole honing machine adopt iron casting bed, is suitable for honing and burnishing cylindrical deep-hole parts, such as various hydraulic cylinders. It can also perform honing and burnishing step holes, and the hole diameter accuracy after honing can reach IT8-IT9, the surface roughness can reach Ra0.2-Ra0.4μm. it can also repair the taper, ellipticity and partial hole tolerance with the partial honing. It can directly perform high efficiency honing of cold drawing steel pipes. This series deep hole honing machine is an ideal machine for deep-hole machining with high accuracy and high efficiency.

Function Description

This machine is mated with CNC system, AC servo moto, travel head with rotating honing rod adopts stepless speed. It is mated with high accuracy racks and gears to realize the reciprocating of honing head and it can control the honing position too. Mated with double linear guide way, so it has long life and high accuracy. The honing head adopt hydraulic constant pressure expanding. Sand blades always maintain constant pressure to be sure the roundness and cylindricity of the workpiece. Honing pressure can be adjusted according to requirement and its device for high- and low-pressure control can realize the rough and finish honing on the operate station. The machine’s other equipment such as hydraulic valve, automatic lubrication station is using the well-known brand products.

Of course, the CNC system, linear guide way and hydraulic valve can also be chosen by customer.
