With the credit of inventing the Swiss style machining process, Jakob Schweizer, a watch maker from Switzerland, changed the way small parts were manufactured. Perfecting his first proto-type lathe in 1872-1873, Schweizer came up with an ingenious invention; the sliding headstock. This feature assured simultaneous rotation of the material and longitudinal movement and radial tool holders carrying out simple forwards and backwards movements. Swiss style machines were later produced on a larger scale in the 1880’s by Nicolas Junker of Switzerland. Inspired by the process of making Swiss watches, Swiss CNC screw machines provide high precision machining solutions by a process of moving material that is rotating through a guide bushing along the Z-axis while keeping the tools stationary. This way, smaller diameter parts that are longer in length than conventional turning can be produced. This type of specialized tool cutting allows the machine to perform several operations at once and in a shorter amount of time.
Swiss type screw machines feature a sliding headstock and guide bushing. The bar stock, which is normally 12-foot metal or plastic bars, are held and rotated by the sliding headstock. This part of the machine holds and rotates the bar stock at speeds ranging from 1000 RPM to 10,000 RPM. The RPM is determined for each product by the diameter and type of material used. A conventional lather simply cannot produce the parts that a Swiss-type screw machine can.
Industries that require Swiss CNC screw machine products include aerospace, industrial automation, medical, microwave, optics, copper consumable market, hardware and plumbing, water flow control, agricultural, electronic, military, defense, robotics and oil and gas. A new avenue for Swiss CNC machine products are featured in the alternative energy industry. Swiss CNC machined products accompany systems that harness alternative sources of energy, such as solar panel systems. While the world is shifting towards renewable energy sources, more and more Swiss CNC machined products will be needed.
Swiss CNC machine products are also vital to the medical industry. Medical equipment like catheters, ultrasound machines, CT scanners, handheld surgical devices, litigation devices and more include Swiss CNC machined products. Parts for the aerospace industry include aerospace couplers, flanges, retainer rings, aircraft seat frames, guidance fins and much more. On a more general scale, Swiss CNC machine products are also included in optical measurement components, guidance systems, watch industry components, microcomputer fittings and connectors, robotic mechanisms and fuel systems.
Swiss CNC screw machines are known for their extremely tight tolerances, auto bar feeders, in which 15-20 bars can be placed and fed through the machine, can maintain a tolerance of just (+/-) 0.0001 of an inch. From boring and deburring to broaching, deep-hole drilling, and threading, Swiss CNC screw machines can operate on a broad array of sizes, shapes, and material measuring up to 24 inches in length and between 1/8 of an inch to 1.25 inches in diameter. Processes include drilling, turning, milling, boring, knurling and many special processes.
