Description

Product details

◆ This machine belongs to the category of surface finishing, which is used to improve the surface roughness of the workpiece. The shape accuracy is guaranteed by the milling of the previous process.

◆ It belongs to flexible grinding. Because of the control of the servo pressure shaft, the contact wheel drives the belt to continuously adjust the grinding force to make it constant, also known as constant force grinding.

◆ “6+1” axis control technology: 6 axes (X\Y\Z, A\B\C) linkage +1 servo pressure axes.

◆ Typical machining parts: steam turbine blades, see the figure below.

$产品详细介绍 ◆ 本机床属于表面光整加工范畴，用于提高工件表面粗糙度，其形状精度由上道工序铣削保证。 ◆ 属于柔性磨削，因为有了伺服压力轴的控制，接触轮带动砂带不断调整磨削力，使之恒定，又称恒力磨削。 ◆ “6+1”轴控制技术：6轴（X\Y\Z,A\B\C）联动+1个伺服压力轴。 ◆ 典型加工件：汽轮机叶片，见下图。$

At present, most of the blade polishing is hand-polished, which is labor intensive and difficult to guarantee. As the size of the workpiece is getting larger and larger, the manpower is no longer competent. The domestic key blade manufacturers purchase imported equipment for processing, the equipment is expensive, the cost is high, the technology is complicated, especially the programming requirements are high, and the foreign technical services are often not guaranteed. Therefore, the price/performance advantage is self-evident and can completely replace imports.
