摘要： PURPOSE:To grind the work in uniformed depth and in precision by enabling to change arbitrarily the pressed amount of belt for grinding on the work in the titled apparatus to grind partially such a surface of work having a desired curved surface as a cylinder. CONSTITUTION:Grinding head 8, each feed gear and measuring sensor 11 are connected with a micro computer. At the time of grinding when grinding position and grinding amount are instructed, the grinding head 8 moves its head to the grinding position of the work through cash feed gear. Further, the area to be eliminated and the depth of elimination are calculated out from the instructed eliminating amount, and the head 8 repeats swinging axially to left and right, the work does swinging synchronously with the left and right motion through holder 4. The sensor 11 is arranged at two points or more in accordance with the work's charactteristics among the measuring points (a)-(g), and the depth of elimination is calculated out from the balance of distance from the sensors for the eliminated partIand the uneliminated part II to the surface of work.
摘要翻译：目的：通过在标题装置的工件上任意地改变用于研磨的带的压制量，以均匀深度和精度研磨工件，以将具有所需曲面的工件的一部分作为圆筒研磨。构成：研磨头8，每个进给齿轮和测量传感器11与微型计算机连接。在研磨位置和磨削量被指示时，研磨头8将其头部通过货币供给齿轮将其头部移动到工件的研磨位置。此外，根据指示的消除量计算要消除的区域和消除深度，并且头部8重复地向左和向右轴向摆动，工件与通过保持器4的左右运动同步地摆动。传感器 11根据工件的测量点（a） - （g）之间的工作特征，将两个点或更多个排列，并从消除部分的传感器的距离和未使用的部分II计算出消除深度到工作的表面。

摘要： PURPOSE:To upgrade the endurability and strength of laminated belt by using a specific material proper to the belt, while performing endless rolling under a strict and specific circumferential length control on each single belt to be laminated and eliminating the clearance between each single belt. CONSTITUTION:A thin wall seamless steel pipe made of maraging steel is cut transversely by a specified width and a base belt which constitutes the innermost periphery of laminated belts. Then, the base belt is led around a roll A and a roll B and is rolled by a roll C from outside under the state where a definite tension is applied between the rolls A and B. To produce the difference of circumferential length so as to laminate an n-th belt, the amount of movement between the rolls A and B, H is controlled so as to satisfy DELTAH=piT(n-1) while, the above tension is maintained regardless of the rolling process when the formula 2pit(n-1) is satisfied (t stands for the thickness of a single belt.). An n number of single belts thus manufactured are laminated.
