Client Reviews on Precision Tooling

After the first month of using Mathawker's multi-axis CNC milling for our stamping dies, the difference in repeatability is clear. The axial backlash elimination they promised is real — our die components now hold ±5 micron tolerances consistently. The setup documentation was thorough, and the team answered our questions about toolpath optimization within hours. We've already reduced our secondary finishing passes by 30%.

Communication during the setup phase was straightforward. The engineers explained the tradeoffs between wire EDM and sinker EDM for our cooling channel requirements. They recommended a specific erosion parameter set that minimized recast layer on our D2 tool steel. The only hiccup was a two-day delay in the initial fixture design review, but the final part met all dimensional specs on the first CMM inspection.

This is our third project with Mathawker, and the consistency across orders is what keeps us coming back. The vertical turning on our 1.8-meter bolster plate achieved a surface finish of Ra 0.3 µm, which is better than the Ra 0.4 µm we specified. They also flagged a potential concentricity issue with our guide post design before machining started, saving us a costly rework. The follow-up support after delivery was prompt and practical.
