On-Site Machining Services

When your equipment breaks down due to a component failure, shipping your part off for repairs can take weeks or months. For critical operations, this kind of downtime is simply not feasible. Instead of sending your part to an off-site machinist for repair or replacement, you can partner with an on-sitemachining service who will conduct repairs right at your facility. Marshall Industrial Technologies offers on-site machining services that bring the machining equipment to your worksite, so you can save both time and money.

What Are On-Site Machining Services?

On-site machining services, also known as portable machining services, are critical for correcting field equipment breakdowns. With on-site machining, you are no longer subject to the vagaries of shipping lines and third-party wait times. You receive top-quality, accurate machining services right at the site of the breakdown. The benefits of portable machining services include:

  • Lower Risk. When machining on-site, you reduce the risk of further damage by eliminating shipping and handling.
  • Schedule Flexibility. On-site machinists work with your schedule, so you can answer questions, make adjustments, and discuss your needs directly with the machinist in real-time. 
  • Greater Control. With on-site machinists, you enjoy direct communication, which allows for much more control over the repair process and finished product quality.
  • Quicker Turnaround. Rather than waiting for your equipment to be shipped between different sites, you can get it repaired immediately on site, for faster repair turnarounds.
  • Reduced Downtime. Quicker turnaround from on-site services means less downtime, so you can get your operation back up and running at full capacity.
