Hydraulic cylinder manufacturers discover improved production rates when using a UNISIG S-Series machine to finish their cylinder interiors. The single-pass skiving and roller burnishing operation is extremely efficient and accurate on these machines, and this S600-3M model example helps to illustrate the features of UNISIGs S-Series.

With the flexibility of its universal table for part fixturing, UNISIG’s UNE40-1500-FT deep hole drilling machine offers manufacturers a unique opportunity to bring gundrilling operations in-house. This machine has a max tool speed of 6000 RPM (max work speed of 400 RPM), and can gundrill up to 40 mm [1.57 in] in diameter and up to 1500 mm [59 in] in depth. It features a fully enclosed working envelope, yet allows full access via the front doors and a removable end panel for ease of part loading/unloading.

Deep hole drilling on a production scale meets high accuracy standards with UNISIG’s UNI-25BTA-4-750 4-spindle drilling machine. With its smart conveyor loading and unloading 4 parts at once and four spindles drilling up to 1 inch [25mm] in diameter and up to 30 inches [750mm] in depth, this machine was built for accuracy and high volume deep hole drilling.

An overview of the feature-rich UNE12-2-750-CR from UNISIG. Its two spindles are capable of precision gundrilling to 12mm in diameter and 750mm in depth — at 12,000 rpm, adding a great deal of productivity within a compact footprint. This fully enclosed machine boasts over 2,000 psi coolant pressure with a contained chip collection system and touchscreen control panel. Counter-rotation of cylindrical workpieces ensures improved hole straightness. UNISIG builds this gundrilling machine to be automation-ready, and frequently integrates robots with its products.

Expertly automated for continuous, synchronous production. The UNI gundrills 4 parts at once, while 2 gundrilled parts are precision reamed and 2 parts receive the final step of button rifling.
