摘要： A flexible screw type height control device comprises a housing, a servomotor mounted in the housing, a driving gear which is rotated by the servomotor, a driven gear which is provided with a spiral groove at a central portion thereof and is tooth-engaged with the driving gear, a flexible screw member which passes axially through the spiral groove of the driven gear and moves linearly upward and downward by the servomotor, and a telescopic unit including a plurality of sliding members which are slidably coupled to each other and cooperate with the flexible screw member. The flexible screw member is a coil spring. A first sliding member is slidably disposed in the housing. One end of the flexible screw member is extended outside the housing, and the other end is fixed to a last sliding member. Each sliding member is formed as an open-ended pipe and a cross-sectional area of the sliding members decreases from the first sliding member to the last sliding member.

摘要： There is provided a drill bit capable of performing a continuous drilling operation on a high-strength workpiece such as a tempered tile and the like. The drill bit comprises a bit body having a receptor portion formed therein, the receptor portion being filled with a cutting oil; a drilling portion extended from one end of the bit body and coupled to the receptor portion of the bit body to form a channel in which a capillary phenomenon occurs, and having an opening formed in one end thereof; and a cutting portion provided in the opening of the drilling portion to drill a workpiece. The drill bit thus configured may be useful to enable a continuous drilling operation on the high-strength workpiece, to enable the refilling of a cutting oil used to cool the high-strength workpiece, to shorten a time for the drilling operation on the high-strength workpiece, and to drill the high-strength work-piece to the maximum extent using the minimum number of drill bits.
摘要翻译：提供了能够对诸如回火砖等的高强度工件进行连续钻孔操作的钻头。所述钻头包括具有形成在其中的接收部分的钻头体，所述受体部分填充有切削油; 钻头部分从钻头体的一端延伸并且联接到钻头体的接收器部分以形成毛细管现象发生的通道，并且在其一端形成有开口; 以及设置在钻孔部分的开口中以切割工件的切割部分。如此构造的钻头可以用于在高强度工件上进行连续钻孔操作，以便能够重新填充用于冷却高强度工件的切削油，以缩短在高强度工件上进行钻孔操作的时间。使用最少数量的钻头，最大限度地钻高强度工件。

摘要： There is provided a drill bit comprising a bit body having a receptor portion formed therein, the receptor portion being filled with a cutting oil; a drilling portion extended from one end of the bit body, having a channel coupled to the receptor portion formed therein, and having an opening formed in one end thereof and connected to the channel; and a cutting portion provided at a periphery of the opening of the drilling portion for drilling a workpiece, wherein the channel of the drilling portion has a small diameter in order that the cutting oil is not discharged outside of the channel by external pressure or gravitational force, and the channel of the drilling portion has a structure in which capillary action occurs due to cut chips flowing through the channel during drilling of the workpiece so that the cutting oil may be discharged by the capillary action.
