Abstract

PURPOSE:To prevent deflection of a center column, which is to be caused by difference in the machining load between coarse and finish processings, and to absorb vibration by equipping the bed and center column with supports. CONSTITUTION:An index table 2 and a center column 3 are installed in the center of the base 1, and a feed unit 4 and a nut runner 5 on the side face. A coarse, medium and finish processing unit 6-8 are installed on said unit 4, and a work set in a fitting tool 9 is processed. This bed and center column 3 are fastened by a cross-support 10 and a stay 11. The work clamped by said nut runner 5 is indexed by the table 2 and undergoes coarse, medium and fine processing, when possible deflection of the column 3 by the machining load at the time of coarse processing is suppressed by the cross-support 10 and stay 11, which will allow the fine processing to be performed in a better precision.

【発明の詳細な説明】 〔発明の利用分野〕 本発明は荒加工と仕上加工を同時に行なうセンターコラ
ム形インデックスマシンに関するものでちる。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a center column type indexing machine that performs rough machining and finishing machining simultaneously.

〔発明の背景〕[Background of the invention]

ンターコラムがたわみ、仕上加工の加工精度に悪影響を
与えていた。With conventional center column type indexing machines, the cutting load during rough machining is significantly larger than that during finishing machining, so the center column deflects and the finishing process is difficult. This had a negative impact on the machining accuracy.

また荒加工時の振動がもろに仕上加工側に伝わり、面粗
度等にも悪影響を与える欠点を有しでいた。In addition, vibrations during rough machining are transmitted to the finish machining side, which has the disadvantage of adversely affecting surface roughness and the like.

マシンを提供するにある。The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to meet the requirements for finishing accuracy and surface roughness without being affected by rough machining, even when rough machining and finishing machining are performed simultaneously. To provide a center column type indexing machine that is capable of

On top of the feed unit are a cutting unit 6 for rough machining, a cutting unit 7 for semi-finishing, and a cutting unit 7 for finishing. It has a structure in which a cutting unit 8 is attached and a workpiece set in a fixture 9 is processed. The bed and the center column are fastened together by a cross support 10 and a strut 11.

に与える悪影響を防止することができる。The workpiece clamped by the nut runner 5 is indexed to a rough machining station by an index table 2, and rough-machined by a feed unit 4 and a cutting unit 6 for rough machining. Similarly, semi-finishing and finishing are performed. At this time, cross support 1° supports 1 to prevent the column from deflecting due to the cutting load of rough machining.
1 is the limit. This can prevent the adverse effects of rough machining on finishing machining.
