Transfer Machine’s Removable Spindles Ease Tool Presetting

Mikron’s Multistar transfer machine enables complete machining of small precision parts in large production volumes. The modular system comes in three models: the LX, which can machine on 12 or 24 stations; the CX, featuring 24 monoblock or adjustable stations; and the NX, equipped with 24 CNC stations. The product performs numerous processes including drilling, milling, thread cutting, turning, recessing, deep-hole drilling, burnishing, grinding, edging, chiseling, stamping, bending, assembly and measuring. The working spindles can be inserted into or released from the machining station, enabling tool setting off of the machine.

The system locks the turntable in place using two diametrically opposite indexing pins and has a table indexing accuracy of ±2.5 microns. According to the company, measurement operations and dimensional corrections are integrated into the machining process, enabling the machine to separate defective parts.

The product uses rotating spring chucks to promote transverse machining and to enable concentricity for turning and plunge cutting operations. Additionally, the system distributes chuck clamping force on the outer edges of parts to prevent workpieces from becoming deformed.

The product machines steel, nonferrous metals or aluminum with diameters ranging from 0.4 to 30 mm and lengths ranging to 60 mm. The machine can perform simultaneous, double-sided machining on 12 or 24 stations with as many as 150 switching cycles/min. The system can produce as many as 600 parts/min.

According to the company, the machine uses various loading systems including a vibratory, linear or inclined conveyor, and a pick-and-place system for loading parts directly from the feed or pallet.
