Cincinnati manufacturer Nilpeter makes five models of flexographic presses that include a number of high-precision machined parts. One such family of parts is a series of impression cylinders that are critical components of each press. A typical Nilpeter flexographic press has eight impression rollers. Each roller must be precisely machined to final diameter tolerances of +/- 0.00005” in order to evenly apply images to the label material. Each roller in this family of parts has slightly different diameter dimensions, ranging from 2.2621” through 2.2618” Steve’s challenge was to reduce production time for these and other press components.

The manufacturing process for each roller included a series of seven steps:

1. The 1215 stainless steel bar stock was cut to length
2. The stock was then blanked
3. The blank was faced on a manual lathe
4. The part was sent out for gun drilling
5. Upon return to Nilpeter, the part was turned on a CNC lathe
6. Following turning, the part was sent out for pre-grinding and chroming
7. The part returned to Nilpeter for finish grinding

Quickly and efficiently machining unusually long or large parts within tight tolerances can be challenging. To solve this problem Okuma developed a line of double column machining centers that use an innovative, bridge-built architecture to provide a solid and rigid foundation for precise machining.

Okuma horizontal machining centers include a number of unique capabilities including the Thermo-Friendly Concept to control thermal deformation, a broad range of spindles and horsepower to match your requirements, THINC intelligent controls, and other productivity-enhancing features.

Dealing with temperature variations to maintain acceptable tolerances of machined parts can rob your operation of productivity and profitability. That’s why Okuma developed its Thermo-Friendly Concept to both reduce heat generated in the machining process and to compensate for any remaining heat. 

The first step is to design machines to better manage deformation with what Okuma terms “thermally symmetrical structures.” This involves viewing the various machine components as individual building blocks, and designing covers and peripherals to eliminate hot spots.

The need for increased precision and greater reliability in parts manufacturing has driven computer numerical control (CNC) technology for the last four decades. Since its birth in the early seventies, CNC machine tool technology has led the way in increased production and faster turnaround times. Gosiger provides CNC machine tools that help make our customers’ manufacturing more profitable and efficient.

Gosiger is dedicated to providing the right CNC machine for your production goals. We offer a variety of high-quality CNC machine options including 5-axis CNC machining centers. A 5-axis machining center provides many advantages over traditional machining centers with fewer axes.
