变得不仅仅是妈妈和流行赛车

两个主要因素刺激了丹和南希卡尼，与他们的儿子布拉德一起，在印第安纳州沙斯普尔斯坦普斯维尔的房屋内开始自己的机器店。一个事实上，他们可以为争夺赛车共同体的需求提供多年的拖累赛车共同体。另一方面，他们所有工作的制造业都是挣扎的，他们的工作似乎并不是那么安全。

The Carneys opted to take their future in their own hands, opening Carney Custom Machining in early 2004. Initially, they specialized in supplying drag racing car builders with special one-off components such as brackets and plates that the car builders couldn’t make for themselves. In fact, the shop that now houses two VMCs, one CNC lathe, a CNC sheet metal bender and other conventional shop equipment was originally built in 1998 as the garage for a top fuel dragster team for which Dan served as crew chief. In the back of their minds, though, they knew that garage would end up being their machine shop.

丹和南希都有19年的金属加工体验。丹是一名机械师和机器维修人员，南希是一个模型制造商。布拉德也是一个5年的模型制造商。这种经历与赛车汉语丹和布拉德聚集在飙车竞争的最高水平上聚集扳手促成了他们的早期成功。通常，甘蔗能够建议改变设计改变以改善分量强度和/或功能。他们还能够在多年来与赛车共同体互动，开发一个健康的客户群。

购买的第一个机床购买的是一个10,000 rpm的vadal vmc 4020，它让他们的业务迅速。然而，很明显，只需一个Motorsport即可提供支持商店所需的工作量。因此，甘蔗队开始与其他行业和市场联系。在这种策略中，CNC转向的增加发挥了关键作用。自2005年购买Amera Seiki T-312双轴CNC车床以来，该商店能够从本地模具商店等资源中汲取工作，这些商店没有CNC转动能力，机器人制造商和汽车售后市场客户。

有两个VMC和一个数控车床，商店不能被认为是一个“转弯”商店。然而，CNC转向是赢得新客户的新工作的好运。

The Right Turn

Amera Seiki T-312车床是商店购买的第二台机床。它有一个12英寸的卡盘和12个炮塔站，提供30英寸的Z轴行程。甘蔗挤压了一些大工作岗位进入这30英寸。

允许车床在无人值守的延伸中操作的钥匙之一是在消耗它之前连续地将Barstock输送到加工环境中。基本上有两种方法可以这样做：可以使用条形送料器向机器推入机器，或者可以使用条形拉动仪通过主轴。鉴于他们目前适度的Barstock工作水平，Carneys决定使用皇家产品的较低昂贵的酒吧拉拔器。条形图在炮塔站中安装类似于工具。炮塔定位拉动器以握住可调节的弹簧钢手指的杆。然后炮塔沿Z轴缩回，使一部分杆成为工作区。一旦在该部分完成转动和部件截止，过程重复过程直到禁用栏。

The Carneys use the bar puller for mold components such as guide posts. In addition, some of the lathe work has been machining gears and sprockets that might be faced, broached or drilled and then cut from gear barstock. The bar puller pulls this spline-like barstock as effectively as solid barstock.

The T-312 lathe has a Fanuc 0i control with an optional Manual Guide conversational programming package. The Carneys opted for this package believing it would be a programming time saver, and it has been. Manual Guide automatically creates blocks of machining code as an operator inputs information related to job start; the various turning operation cycles and tool changes; and the end program. In addition, it is possible to program the lathe to machine a specific number of parts in a row from barstock depending on total bar length. The programming package also offers machining simulation to check for interferences and other problems prior to actual machining. CAD capability allows parts to be drawn at the machine control without offline CAD/CAM software.

一个大转

最近的工作之一是一个用于套装车的大型汽车轮。车轮以伪造的铝坯开头，与诸多作为两个组件启动的许多其他定制轮子 - 一个轮辋和中心部分。加工两件式轮子的挑战性较低，因为这两个部件可以作为单独的碎片加工，然后焊接在一起。

一体式轮空白是另一个故事。首先，在其中一个VMC上铣削安装到轴轮毂的车轮的背面。然后，车轮需要用于内外边缘轮廓的转动操作。发现用于夹持车轮的最有效的方式是用于转动操作的是创建圆柱形铝适配器，以将进入卡盘安装。转动适配器以创建轴轮毂配置文件。此外，丹创建了定位的螺纹孔，以匹配车轮的螺栓图案并在孔中安装螺柱。这样，适配器被夹住，并指示其集线器轮廓，然后将车轮固定到适配器上使用坚果，就像汽车的轴毂一样。

车轮的直径大尺寸为20英寸，12英寸宽创造了用于转动外轮辋剖面的工具挑战（此轮廓的横截面大致类似于宽字母“U”）。虽然镗杆转动内边缘表面，但这种直线工具无法进入边缘外部轮廓的谷。所以丹创造了一个右手工具，围绕边缘的嘴唇（右边的照片）。Beefy工具有一个长条，跨越整个炮塔直径并锁定到两个相对的炮塔站。这有助于在切割过程中支撑重型工具。

Because of the wheel’s width, however, the tool cannot turn the entire outer profile in one setup. The tool is able to reach just past the center of the rim before the turret would collide with the wheel. In order to turn the other half of the rim, the wheel must be removed and reversed. After that, the wheel goes back to one of the VMCs to mill the spokes in the center section and drill the valve stem hole.

在路上

During my visit, the Carneys were in the process of applying epoxy paint to the shop floor. That’ll make cleanup easier, and the shop will look even cleaner than it already appears. However, a new, larger facility may be in the cards as business continues to grow. Earlier this year the Carneys added a second Fadal VMC 4020. This one has an optional 28 inches of Z axis travel to accommodate taller workpieces. They’re also considering a waterjet machine to allow them to expand into additional markets and work with a wider range of materials.

我还指出，在后院中有CNC转动和铣削能力有一个副作用。丹已经为1948年的庞蒂亚克创造了许多铝制品，如室内门把手，旋钮，发动机滑轮，杯架和气体和制动踏板。他正在滋补加工自己的轮子，为汤边的四门巡洋舰加工自己的轮子。也就是说，他承认，找时间更难以找到在车上工作，因为商店已经忙碌了。如果Carneys留在当前的道路上，事情可能会在路上忙碌。
