Machine Rebuilding

Acme Gridley Rebuild 2016

BME offers complete rebuilding services for Acme-Gridley mutli-spindle bar automatics. Along with rebuilding the base machine, we also offer a complete turn-key tooled machine to fit the customer’s needs.  Our mission is to supply our customer with all the means necessary to run their job, not just a piece of equipment.  This starts from the time of proposal where we provide a detailed proposal to the customer, specifically describing our intended scope of work, minimizing the confusion of what is actually being purchased, and minimizing the need for change orders.  It carries on after placement of the order, where bi-weekly Gantt Chart updates and pictures are provided to the customer, along with documented  “test” results of the rebuilt machine are shared with the customer.  After samples have been submitted and a runoff on BME’s floor is conducted, where we encourage your operators take part in being fully trained on how to operate the machine and adjust the tooling, we duplicate the process on your floor after the machine has shipped.  And typically it doesn’t end there, we always pick up the phone to lend our heads in solving a new challenge your staff may have with the project, long after shipment of the equipment.  This outlook has allowed us to build very successful relationships with our customers, encouraging repeat projects. 

Since we are also a manufacturer of tooling, we have the on-site manufacturing capabilities to rebuild and retool, thus controlling the cost and lead times of our projects.  Our staff includes personnel that have a combined 80 plus years of experience in diagnosing, designing, and debugging a variety of solutions to customer’s challenges on screw machines.  We have been able to rebuild machines for jobs that customers currently have been running, and with our “outsiders” approach to the job, yield 20-30% increases in parts per hour. All of our rebuilds come equipped with the Logan CS 2001 control package that includes tool counters and lock up detection, along with additional simple programmable inputs and outputs for auxiliary equipment that may be added much later in the life of the machine.  Click here for a link to Logan CS 2001 control package

If it’s a standard bar machine your looking for, or converting a bar machine to a “chucker” application, please contact us for a quote.  We will provide a detailed proposal for your machine, so you will know exactly what you are purchasing, and will not be upsold after the initial order (add link to the contact page). Don’t have an existing machine to rebuild but need one, contact us.  Between what we have on our floor currently, and our network of users that do, we can find one to fit your needs.
