通过采用滚针,可减轻突入时的碰撞、摩擦、振动,实现超高精度的直线运动。另外,精密滚针导柱与滚珠导柱相比,滚针可分散压 力,从而可大幅提高导柱的使用寿命,是“ 直线运动导柱的终极形态”。

低振动
Low vibration
通过采用高精度的宽幅滚针,在确保刚性的同时,实现了低预压化。 这样,实现了超低振动且平滑的滚动。
By adopting highly accurate wide roller, we can make low pre-load with high rigidity on Million guide. For this reason, we've realized super low vibration and smooth rolling.
滚针式的特点
Advantages of Roller type
滚珠循环式
Circular ball type
滚珠之间相互接触、碰撞,从而产生摩擦,导致磨损、发尘、发热。另外,循环时反复进行预压突入、解除,是引起振动的主要原因。
Ball contact/collision makes friction, leading to wear, dust and heat emission. The pre-load off and on are repeated at the ball circulation, and it makes one of major vibration factors.
精密滚针导柱(滚针式)
Million Guide (Roller type)
滚针之间无接触,不会发生滚动体的接触、碰撞、摩擦。另外,由于非循环、低预压,突入冲击、振动小,可实现平滑滚动。
Rollers do not contact each other, and no contact, collision and friction occurs to rolling elements. No circulation and low pre-load structure makes less entry impact and vibration, leading to smooth rolling.
滚珠型相比 振动仅为其1/20以下
Low vibration under 1/20 compared to that of ball type.

微小滚动阻力
Infinitesimal rolling resistance
由于实现了低预压化,最大程度地降低了滚动阻力,20g以下也可制作。※
⇒适用于需要进行微小压力控制的用途。
By making low pre-load on Million guide, it reduces rolling resistance to the utmost limit so the sliding friction can be under 20g.*
⇒ It is the best for applications which need infinitesimal pressurizing force control.
※某些尺寸可能不适用。*There is a limit by size.
5.
可单轴使用
Usable with Single shaft
滚针采取多平面配置,具有防止旋转的效果。
⇒导柱可单轴使用。可简化装置。
By arranging rollers in polygonal position, it can get detent effect.
⇒ It is usable with single shaft guide so that the equipment can be simple.
滚珠导柱
Ball guide case
为保持刚性,滚珠需突入很大的预压 量5~12μm,会产生冲击、振动,寿命短。
Higher pre-load (5-12μm) for keeping the rigidity on the ball guide brings impact/ vibration at the entry, leading to shorter product life.
精密滚针导柱
Million guide case
滚针只需微小的预压量2~6μm,即可实 现高刚性,突入时冲击小、平滑,寿命长。
Lower pre-load (2-6mm) for the roller with high rigidity brings smaller impact and smooth motion at the entry, leading to longer product life.
滚珠导柱

模具的上下模间隙在整个圆周上可保持均匀,提高了尺寸精度。另外,由于 提高了刚性,减少了上下模的崩角现象,可延长模具的再磨削周期。

The punching accuracy is expected to be increased by Million guide to keep the clearance between the punching and the die evenly in all directions. Also the die set regrinding cycle is expected to be extended by decreasing the chipping of the punching and the die with its higher rigidity.
