Problems solved by technology

Even if the reciprocating frame moves at full speed, the cutting speed to obtain a high-precision processing surface is insufficient, so that the ultra-precision processing surface required by the mold for forming the lens sheet cannot be obtained.

Embodiment Construction

[0024] Hereinafter, one embodiment of the precision roll lathe of the present invention will be described with reference to the drawings.

[0025] Fig. 1 is a side view of the precision roll lathe of the present invention, and Fig. 2 is a top view of the precision roll lathe.

[0026] In FIGS. 1 and 2 , reference numeral 10 denotes a base on which a main shaft frame 12 , a tailstock 14 , and a reciprocating frame 16 are disposed. The workpiece is a roll-shaped workpiece W, which is rotatably supported by the headstock 12 and the tailstock 14 .

[0027] The spindle frame 12 is disposed at one end portion of the base 10 in the longitudinal direction. The spindle frame 12 includes a main body 17 , a spindle 18 , a chuck 19 mounted on the front end of the spindle 18 , and a servo motor 20 for driving the spindle 18 . The main shaft 18 is supported by an unillustrated hydrostatic bearing built into the main body 17 . The chuck 19 holds the workpiece W and transmits the rotation ...

Abstract

There is provided a precision roll turning lathe includes: a bed 10; a headstock 12, mounted on the bed 10, for rotating a roll-shaped workpiece while holding one end of the workpiece by means of a chuck, said headstock having an indexing axis (C axis) for performing circumferential indexing of the workpiece; a tail stock 14, mounted on the bed 10 and disposed opposite the headstock 12, for rotatably supporting the other end of the workpiece; a carriage 16 including a saddle 26 mounted on the bed 10 movably in the longitudinal direction (Z-axis direction) of the workpiece, and a table 28 mounted on the saddle 26 movably in a direction (X-axis direction) perpendicular to the longitudinal direction of the workpiece; a tool swivel 30 mounted on the table 28 and having an indexing axis (B axis); a tool post 33 mounted on the tool swivel 30 and having a plurality of cutting tools 36 attached thereto; and a fly cutter spindle device 34 mounted to the tool post 33. The precision roll turning lathe can not only machine with high precision circumferential transverse grooves in the peripheral surface of a roll but can also machine with high precision longitudinal grooves in the peripheral surface.

Description

technical field [0001] The present invention relates to a precision lathe for machining roll grooves, in particular to a precision roll lathe capable of machining not only circumferential grooves on the outer circumference of the roll but also axial grooves with high precision. Background technique [0002] Roll grinders and roll lathes are examples of work machines that process rolls. The roll grinder is equipped with a spindle frame, a tailstock, and a reciprocating frame, and a grinding tool is installed on the reciprocating frame. [0003] Conventionally, in a roll grinder, in addition to grinding the outer peripheral surface of the roll with a grinding tool, grooves are also processed on the outer peripheral surface. Patent Document 1 describes a roll grinder in which a grooving device having cutting teeth for cutting grooves is installed on a reciprocating frame. [0004] The roll lathe is a lathe in which the tool holder equipped with the diamond turning tool is set...
