Expand Machinery’s Genturn-52 CS Simplifies Setup, Reduces Costs
Sliding headstock machine has no guide bushing, thus simplifying setup while reducing job expenses and setup time.
Expand Machinery’s Genturn-52CS Y2
Expand Machinery’s Genturn-52CS Y2 is a 2" bar capacity, 8-axis Swiss-type turning center, featuring a subspindle and dual C and Y axes for producing complex work in just one handling. There is no guide bushing in this sliding headstock machine, thus simplifying setup while reducing job expenses and setup time.
The company says ample tool stations are provided to get the work done efficiently in just one set up with 33 tool positions and 13-driven tools included. There are 20 tool stations servicing the front side work and an additional 13 backworking tool positions that come standard. The 20 front side tool positions consist of six live cross tools, three live axial tools, six turning tool stations and ID tool stations, all in a quick access gang configuration to reduce tool-to-tool time.
The counter spindle has 13 tool stations, including four axial driven stations with four live tool holders included. An additional four driven tools can be plugged into the subspindle tool block, as needed. Also included are nine ID stations, four ID stations from the dedicated subspindle tool block, and five ID stations shared from the backside of the main spindle tooling bridge.
According to the company, the Genturn-52CS Y2 CNC Swiss is a very robust, rigid machine with a heavy ribbed torque-tube box casting. The machine weighs over 13,800 lbs, making it the heaviest machine in its class, the company says. Both main and counter spindle feature accurate dead-length gripping and a high-performance C-axis with full contouring and 360,000 radial positions (0.001-degree resolution). C-axis operations facilitate engraving and milling highly complex part details. The 51 mm (2") bar capacity spindle runs up to 6,000 rpm and the rapid traverse rate is 1,181 ipm for fast, efficient production.
This article discusses the use of high-speed spindles in Swiss machining applications. Sufficient rotational speed is necessary to take advantage of tooling materials in small diameter cutters.
Hard turning can be a cost effective alternative for shops looking to streamline part processing.
Hard turning isn’t hard to do. However, it does require an understanding of the process dynamics and a systematic approach to the tooling involved. This article looks at how proper preparation will deliver consistent, predictable hard-turning results.
