Abstract

The invention relates to a tool head, a machine tool and a boring method of bore of cylinder block using the machine tool. The spindle drive unit (11) of a combined machine tool (10) drives the spindle (32). The tip end of the spindle (32) is provided with a boring tool (100) and a tool head (30) having a rough grinding stone (102) and a finishing grinding stone (104). The spindle drive unit (11) has a first support unit (34) and a second support unit (36) capable of receiving the spindle (32) therethrough and supporting it rotatably, a linear motor (58) and a column slide mechanism (38) for moving the first and second support unit (34, 36) in the axis direction of the spindle (32), and a spindle motor (44) for rotating the spindle (32).

Description

[0001] This application is a divisional application of the Chinese patent application with the application number 200780017361.5 filed on March 12, 2007 by Honda Technological Co., Ltd. . technical field

[0002] The invention relates to a tool head with a grinding tool, a machine tool with a boring tool and a grinding tool, and a method of boring a cylinder using such a machine tool. Background technique

[0003] Machining treatment for boring a cylinder block constituting an engine component includes: boring treatment (finish boring treatment, etc.) for forming a hole in the cylinder body to a predetermined diameter; and grinding for subsequent grinding of the surface of the hole Treatment (honing treatment, etc.). If the boring and grinding operations can be performed consecutively on a single spindle of the machine tool, the cylinder will not create misalignment with respect to the tool that would otherwise result if the cylinder were moved between different machines an...
