Thousands of good heavy machine tools “go to work” each day, as they have for generations. Today, they are joined by newer, lighter, more complex machines. Subsequently, machine tool repair, rebuild, and retrofit projects come in as many varied sizes and requirements as there are makes and models of machines. Peiffer has the depth of experience and tenacious ingenuity to get your machine tool working — the right way — again.
Machine Tool Repairs
A ‘down’ machine tool is a problem that needs a solution as quickly as possible. Reduced productivity, decreased capacity, and lost revenue…. It’s crucial that you get prompt, expert service to diagnose and fix the problem—ASAP!
Peiffer provides on-site machine tool field service throughout the United States. Our usual response time to service inquiries is 24-48 hours.
Whether machine repairs are made at your location or back at our shop in Pennsylvania, our team will troubleshoot what’s wrong, provide a plan, and make the repairs needed to get you up and running again.

Machine Tool Rebuilds
Machine tool rebuilding, the Peiffer way, involves detailed, “from the ground up” processes to assess, measure, dismantle, catalog, research, scrape, grind, paint, fit, align, and test run. Hydraulics, pneumatics, electrical, mechanical, safety — all aspects of machine operation come under the highest levels of scrutiny to assure like-new operation and accuracy.
You can rely on the machine tool rebuilders at Peiffer to get your rebuild job done right—on time and on budget. Our in-house facilities were built for this work, and our breadth of experience enables us to get it done:
- Complete machine tool disassembly/reassembly
- Expert parts sourcing, machining, and/or reconditioning
- Way Work (including scraping, alignment, and linear way replacement)
- Spindle Repair and Rebuild
- Ball Screw Repair and Replacement

Machine Tool Retrofits
Machine tool retrofits often go hand in hand with machine repair or rebuild projects. A CNC Control Retrofit enables good old machines to do more, with enhanced, easy-to-use functionality and restored reliability.
Peiffer is a FANUC Authorized CNC System Integrator, and our depth of Machine Rebuilding experience ensures your CNC Control Retrofit will be just right for your needs and your budget.
