3MTT4325 CNC High Speed Sphere Base Surface Grinding Machine for Tapered Roller(Grinding and Superfine Processing)
Dec 07, 2017

                           机床扼要介绍Brief Introduction of the Machine Tool

 1、机床主要用于圆锥滚子球基面磨削。采用连续通过式磨削的加工  方式;

The machine tool is mainly used for grinding the sphere base surface of tapered roller. The process of continuous grinding is adopted.

 

2、机床由床身部件、上夹盘部件、下夹盘部件、砂轮轴座部件、砂轮轴座调整部件、防护部件、冷却部件、电气部件等组成。

The machine tool is composed of the lathe bed parts, the upper chuck parts, the lower chuck parts, the sand wheel shaft seat parts, the sand wheel shaft seat adjusting parts, the protective parts, the cooling parts, the electrical parts, etc.

3、机床的上料采用料管强制送料方式输送,将工件有序压入上、下夹盘和隔料盘中。滚子自转并公转,进入磨削区。

The material is forced-fed through the material tube. The workpiece is pressed into the upper and lower chucks, and the material separation plate. Roller rotate and revolve, enter into the grinding zone.

 

4、在床身工作台面上,沿着隔料盘圆周布置有不同粒度的油石,油石的加压采用气缸推动,压力手动调节。

On the surface of the worktable, the oil stones of different sizes are arranged along the circumference of the disc. The pressure of the oil stone is driven by the cylinder, and the pressure is adjusted manually.

 

5、机床的砂轮轴支承采用整体轴承主轴,前后各安装两套成对角接触球轴承,并且后端轴承采用弹簧定压式预紧,主轴受热向后伸长。

The integral bearing spindle is adopted for the grinding wheel shaft support of the machine tool. Two sets of angle contact ball bearings are installed in front and behind respectively. And the rear bearings adopt the spring constant pressure type pretension. When heated, the spindle stretches backward.
