Heavy Duty Deep Hole Honing Machine

Heavy duty deep hole honing machine

Heavy duty deep hole honing machine brief:

2M2150 honing machine is suitable for honing and polishing of cylindrical deep hole workpiece. For example, a variety of hydraulic cylinders, cylinders and other precision pipe fittings. Honing and polishing of workpieces with step holes. Its processing aperture accuracy can reach IT8-IT9 level or above. The surface roughness can reach Ra 0.2-0.4 um. The taper, ellipse and local aperture errors of the workpiece can be corrected by local honing. For some cold-drawn steel pipes, it can be honed directly. 2M2150 is an ideal equipment with high efficiency and high precision.

The honing machine is equipped with Delta PLC control system, AC servo motor, stepless speed regulation of grinding rod box, chain and sprocket to realize the reciprocating motion of honing head, which can accurately control the honing position. At the same time, double linear guideway is adopted, which has higher service life and higher precision. The honing head is expanded by hydraulic constant pressure, and the honing force of the bar is stable to ensure the roundness and cylindricity of the workpiece. The honing pressure can be adjusted according to the need, and the control of high and low pressure can be set. The coarse and fine honing conversion can be realized loosely on the console. Other machine tools with concentrated pressure valves, automatic lubrication stations and other famous products.

The configuration of CNC deep hole grinding machine tool, such as CNC system, linear guide, hydraulic valve, etc. can be selected or specified according to user's requirements.

The machine bed is cast by iron HT300. So it could have a big loading capacity！！！！

Heavy duty honing machine mainly parameters :

Heavy duty honing machine mainly features:

The honing head expansion and tightening is under the servo control,which constant pressure expanding and tightening can be realized.

1. Honing head tightening/expanding pressure is stable. Servo motor set the tightening/expanding pressure by torque,the pressure is constantly.

2. It can inspect the workpiece inner hole automatically,which can realize partial honing,enhance the working efficiency. In the constant pressure mode, the honing head digitally displays the torque of each point in the workpiece during the honing process through the torque display table,  so that we can judge the workpiece inner hole condition. The operator can first partial honing parts of the workpiece with small hole size according to the actual situation, and then througly honing when the aperture is uniform.In this way, Not only the work efficiency can be improved, but also  the cylindricity and straightness of the workpiece can be guaranteed.

3. Servo control can be controlled through CNC system panel,digital read,adjustment accuracy.

Cooling method：External and internal oil feeding combined mode

1. Honing oil go inside through honing bar,which can make the coolant oil form into higher pressure,which will have big force to wash the honing dirties.

2. Internal honing oil feeding can make up the long workpiece honing defect. When honing long workpiece(more than 1.5m),only use external honing oil feeding,which could not cool and wash the honing head,but by internal oil feeding ,which can cool and wash the honing head in time. The threshing of strong honing stone can make the honing stone keep sharp and greatly improve the honing efficiency and processing quality.

3. You can choose external oil feeding method when you processing short workpiece.
