Precitech recently attended the American Society for Precision Engineering (ASPE) conference held in Boston, MA. We took advantage of the close proximity to our office in Keene, NH to send many of our engineers to participate in the tutorial sessions held during the conference. Several members of our global sales force from India, Japan, and China were also able to attend. Precitech had a Levicron high speed milling and grinding spindle on display in our booth.  (large images)
