Metal Cutting Services

Precision metal cutting is what we’re built on, and we work continually to improve our methods to ensure we deliver the quality and precision our customers depend on. Consistent cut-off requires mastery of many variables, and at Metal Cutting our techniques, tools, equipment, and methods all come together on a daily basis to produce accurate and repeatable results.

Burr-Free Abrasive Cutting

We have a huge volume capacity with a vast selection of cutting wheels enabling us to cut every type of metal in every combination of size — from thin wall tubing to hard metals, from to coated metals to composite metals, and everything in between. All of our precision metal cutting machines have been enhanced with various advanced custom features, including:

● Programmable operation for maximum set-up flexibility and change-over speed

● Computerized cutting speeds and feeds

● Linear in-feed encoding to achieve the tightest tolerances and shortest lengths

● Rotary work to yield exceptional squareness

● Pressurized material handling to eliminate tubing ID contamination

● Wheel selection and inventory that eliminate delays and optimize performance

EDM Metal Cutting

Our EDM cut-off is highly specialized for pins, probes, and other high-volume, small diameter, solid metal parts. Our methods result in parts with the highest CpK and PpK process results. We produce highly repeatable lengths, without end deformation, distortion, or delamination — and do it far more economically than competing methods. By minimizing the need for human handling of your cut parts, process damage such as bending or scratching is eliminated. End features such as squareness and parallelism are tightly held and corner radii are minimal, meeting square cut requirements and allowing for subsequent processes to add radii if needed.

Facts About Precision Metal Cutting Services

● Diameters from 0.0005” to 3.00” (0.0125 mm to 75.0 mm)

● Cut lengths from as short as 0.008” (0.20 mm)

● Cut length tolerances down to 0.001” (0.025 mm)

● Defotmation-free cutting of any tube ID — no matter how small the ID — and tube walls as thin as 0.001” (0.025 mm)

● Holding exceptionally tight tolerances on long-length cuts (± 0.005” over 6.0′ or ± 0.125 mm over 2 m)
