On the Radar

Maximum Precision, Minimal Pitch Deviation
Using ball screws in the series BS 22-1.5 enables linear movements with minimum travel variations of a maximum of 5μm over the absolute total travel. Ensuring maximum precision is found when the series is used in combination with motors and mounted components, such as high-resolution encoders, integrated motion controllers, or stepper motors in micro-stepping operations. This is ideal for demanding positioning tasks such as optical filters, glass-fiber technology, and lens adjustment in optical systems. The mechanical connection to the motors is implemented by means of a backlash-free coupling integrated into the lead screw. Numerous modifications, such as variable screw lengths, modified screw nuts, and custom lubricants are available on request for use in special applications.

Jig Borer Refurbishment
Many jig borers can last up to 25 years before reconditioning is needed. When the machine requires attention, Mitsui Seiki can enhance, rebuild, or replace several components. For example, the company typically re-scrapes the table surface. A jig borer’s table is essentially a master gage. It is a qualifying surface in relation to the machine and the precision workpieces. In fact, the jig borer is built from the master table surface, which is the only machine tool type that is constructed that way. Generally, Mitsui Seiki also refits the quill assembly, replaces spindle bearings, integrates a new FANAC control system, rewires the electrical components, and replaces the outdated motors and drives.
