Spindles

Michael Herman, vice president sales for BIG DAISHOWA Inc., discussed a special promotion for the company’s fine boring kit, which features the EWN2-152 fine boring head from BIG KAISER is said to enable manufacturing precise bores with guaranteed precision of .00005". The set comes with dedicated accessories such as a boring bar, screw-in insert holders, and 2 inserts to cover Ø.701"-2.126".

During a tour of the NSK America booth at Eastec 2023, Senior Product Manager Greg Nottoli showcased the company's CTS-3030 high-speed, ultra-precise electric spindle designed to seamlessly transport coolant through the cutting tool.
 

Jack Burley, president and COO of BIG DAISHOWA Inc., took time during Eastec 2023 to highlight a number of the company's products, including tooling technology focused on trochoidal milling, high-precision fine boring heads with digital readouts, and the BIG-PLUS spindle system that is designed so the shank contacts the spindle taper and the spindle face at the same time.
 

Nakanishi E-speed from NSK America Corp. is a broad line of high-speed, ultra-precision, electric-motor spindles for lathes, robotics and specialty purpose machines. Utilizing DC brushless motors up to 80,000 rpm and less than 1 micron runout, E-speed has the right configuration for your micromachining needs, whether it be integral, modular or quick-tool change. The E-speed family consists of E2000, E3000 and E4000 motor spindles.

This brief video from NSK America Corp. shows off the company's new iSpeed5 high-speed electric system, which is said to be capable of running continuously at up to 80,000 rpm using an external controller.

NSK America Corp. offers a three-minute video overview of its HES electric spindle series, which is said to enable conventional milling machines and machining centers to perform high-speed machining, small diameter drilling, and milling with good surface finishes.

When considering options for speed, NSK America Corp. and OSG USA Inc. teamed up to highlight the benefits of proper speed applied to high-quality tooling. For the project, they machined their respective company logos onto a coin to showcase the intricate geometries and engravings that are possible with microtooling. They used a window machining process, along with NSK America’s HES510-CAT50 electric spindle and OSG USA’s AE-LNBD-N 1 mm long-neck, ballnose endmill, to achieve an ultrafine surface finish.
