Before you choose
Questions about SF-720D
What is the maximum speed of the SF-720D?
The catalogue lists 6,000 rpm. This is a maximum rating rather than a guaranteed production rate.
Does direct drive mean automatic thread trimming?
No. Direct drive describes the drive arrangement. The SF-720D entry does not establish automatic trimming or automatic foot lifting; specify those functions separately if needed.
What information is needed for a quotation?
Provide the material, seam sample, stitch configuration, quantity, electrical supply and destination. Confirm the table, stand and any accessories in the quotation.
