PRECISION AXES & PRECISION SYSTEMS

PRECISION AXES & PRECISION SYSTEMS HIWIN positioning systems enable exact positioning in time and place. They are suitable for horizontal and vertical installation positions. Precision axes with ballscrew are especially well suited for applications that require high feed forces and high rigidity. Directly driven axes and systems with linear motor enable backlash-free and highly dynamic operation with low maintenance costs. DOWNLOADS AND APPLICATIONS Assembly instructions

General information 2.1.1 Properties of KK/KF spindle axes HIWIN KK/KF linear axes are compact positioning axes with high feed forces. The high precision and rigidity is achieved by a linear guideway with a ball track built directly into the steel profile. the ballscrew integrated into the block makes the axis especially compact. The axis is available in various sizes and lengths and can be adapted to the requirements of different applications with additional options such as aluminium covers, bellows covers, limit switches and additional blocks. Typical properties - Complete axis ready for installation...

3. Calculation basis3.1 Service life calculation for KK/KF spindle axes3.1.1 Service life calculation The repeated strain of the block and shaft results in signs of fatigue on the surface of the track and ultimately leads to pitting. The service life of a linear axis is defined as the total travel distance covered until pitting occurs on the surface of the track or shaft. The service life can vary greatly even if linear axes are manufactured in the same way and used under the same movement conditions. Therefore, the nominal service life is taken as a reference value for estimating the service...

3.1.2.1 Calculation of the service life of the linear guide Since the load on a block varies greatly, an equivalent load must be included in the calculation of the service life. The equivalent load is defined as the load that causes the same wear on the bearings as the variable load. In this way non-constant operating conditions are taken into consideration. - Combined dynamic equivalent load This formula allows for a simplified calculation of the dynamic equivalent load. Please contact HIWIN if you need more extensive information. Fbm Dynamic equivalent load [N] C0 Static load rating [N] M Directly...
