1" RAN-6 Automatic Multi Spindle Lathes

We have in stock National Acme 1" RAN-6 automatic screw machines for sale, and can rebuild, retool, and/or retrofit any of our used Acme Gridley screw machines to specifically meet your needs. JEM Automatics guarantees the performance of all Acme Gridley screw machines we rebuild. Optionally, turnkey setup services can be provided, where we would supply the machine fully tooled and already proven to produce your part automatically and within tolerance before it is delivered to your plant. 

The Acme Gridley 1" RAN6 screw machine is a 6 spindle automatic lathe bar machine or collet chucker machine. Standard multispindle bar machine specifications and capacities shown are for reference only, as a custom retrofit by JEM may improve upon or modify these specifications. Many of the National Acme standard equipment options and attachments available to configure an Acme Gridley 1" RAN6 screw machine are listed here. Please use our quick RFQ form below and we will review your specific requirements and follow up with a machinery quotation and/or recommendation for your consideration.
