Accuracy of machining on the workpiece can be expected to be 1 µm or better when a CNC machining centre designed with hydrostatic guideway drives is used. The Pyramid Nano from Kern Micro- und Feinwerktechnik GmbH & Co. KG (Murnau-Westried, Germany; ) exhibits positioning scatter according to VDI/DGQ 3441 of ±0.3 µm. This high-precision, high-accuracy performance is achievable throughout the machine’s x-y work envelope of 500 × 500 mm. The machine bed features symmetrical construction from the manufacturer’s own Armorith material. The thermally stable and vibration-dampening base helps the machine to achieve high precision levels. The manufacturer has employed hydrostatic rather than linear drives in the machine design because the former do not create a whipping cogging effect. Hydrostatic guideways lift the machine table 18 µm, thus there are no metal-to-metal contacts or wearing parts. Because the oil in each guideway is temperature controlled, no variation in accuracy among axes will occur, even if one axis is being moved faster and further than another. The hydrostatic guideways allow machined components to be given a good surface finish. This machine comes with either a 6.4-kW HSK-25 spindle running at 500 to 50000 rpm or an 11-kW HSK-40 spindle offering a speed range of 200–36000 rpm. The spindle is housed in the temperature-controlled guideway system of the z-axis. A two-axis torque-drive trunnion table can be equipped with a choice of chucks that provide accurate workpiece positioning and a basis for automated workpiece changing. A tool magazine with up to 95 positions and an integrated workpiece changer with 20 positions or external changers with pallets as large as 280 × 280 mm are available to automate operations. A modular honing machine series is engineered to be scalable from a basic, single-spindle machine to a fully automated multispindle unit with robotic part handling, postprocess air
Products & Services
Milling machines move a clamped workpiece into a fixed, rotating cutter; or move the cutter itself into a stationary workpiece. There are two basic configurations: vertical and horizontal.
Boring tools are used to cut or finish the inner diameter of holes.
Machining centers are machine tools that are used to automatically repeat operations on a workpiece. They are usually numerically controlled. Operations include drilling, reaming, tapping, milling, and boring.
Machine Fences, Stops, and Guides
Machine fences, machine stops and machine guides are use to position and guide a workpiece in saws, routers, and other cutting equipment.
Shapers are machines that are designed to create shapes by removing large amounts of material from metal bars and blocks. They operate by holding and moving a cutting tool in a linear motion against a stationary workpiece.
