Full simultaneous 5-axis capability in Dickson, Tennessee. Complex geometry. Tight tolerances. Single-setup efficiency.
5-axis CNC machining means the cutting tool moves in five directions simultaneously, X, Y, Z, plus two rotational axes. Most shops run 3-axis machines that can only approach a part from directly above. A 5-axis machine tilts and rotates to reach compound angles, curved surfaces, and undercuts without stopping to reposition.
The result: complex parts made in a single setup, with tighter tolerances and faster turnaround than traditional multi-setup machining.
Tier One Machine runs the Haas UMC 500SS, a full simultaneous 5-axis machining center capable of producing highly complex geometry with tolerances to ±0.0002" in a single setup.
Every time a part gets repositioned, there's potential for error. 5-axis machining eliminates most of those repositions, better accuracy, better surface finish, faster delivery.
Every 5-axis job ships with a full CMM inspection report. Dimensional verification on every feature, documented and included in the box.
Tier One Machine is operates under an AS9100-based quality management system. Defense and aerospace suppliers can source 5-axis parts with full compliance confidence.
Complex geometry is our lane. Let's talk.
6-axis turning with live tooling in Dickson, Tennessee. Turn and mill in a single operation, no outsourcing, no extra lead time.
Tier One Machine runs the Haas DS-30Y, a 6-axis turning center with live tooling. We turn and mill a part in a single operation, without sending it to a second machine or a second shop.
Whether you need simple cylindrical parts or complex turned-and-milled components, we handle it all in-house. Faster turnaround, tighter tolerances, one vendor.
Live tooling means milling operations, slots, flats, cross-holes, keyways, happen in the same setup as turning. No re-fixturing, no second machine, no extra handling. The part is more accurate and it's done faster.
Every turned part that ships from Tier One Machine has been dimensionally verified in our CMM lab. The inspection report ships in the box, no extra charge, no special request needed.
Direct shop. No middleman. Fast response.
In-house carbide brazing in Dickson, Tennessee. No subcontractors. No extra lead time. Precision joints with full documentation.
Most machine shops send carbide brazing out to a subcontractor. That adds days to your lead time and introduces another handoff where quality can slip. At Tier One Machine, we braze tungsten carbide in-house.
Our brazing department is run by Trish, a specialist with years of experience producing clean, consistent brazed carbide assemblies. The work stays in our shop, under our quality system, and ships with documentation.
Brazing permanently joins a tungsten carbide insert or tip to a steel or other metal body using a filler metal heated above 450°C. It creates a strong, permanent bond used in cutting tools, wear parts, oil and gas components, mining equipment, and industrial tooling.
Done right, the joint is as strong as the carbide itself. Done wrong, you get delamination, cracking, or voids that fail under load. We've been doing this right for years.
Every brazed assembly goes through our quality system, visual inspection, dimensional verification in our CMM lab, and full documentation. Your parts ship with traceability.
No middleman. Fast turnaround. In-house quality control.
Full dimensional verification on every order, not on request, not on first articles only. It ships in the box. That's the standard.
CMM stands for Coordinate Measuring Machine. It physically touches hundreds of points on a part to verify every feature, hole diameter, depth, position, flatness, runout, against the engineering print.
Most shops inspect occasionally, or only on first articles. At Tier One Machine, CMM inspection is standard. Every job. Every time. The report ships with the parts.
We maintain an in-house CMM lab with calibrated equipment. Our quality system requires dimensional verification on every order before it ships, generating a full report showing measured values versus nominal dimensions and tolerances.
When parts arrive at your facility, you want to install them, not inspect them. CMM reports from a qualified supplier mean you can trust the parts before they go into your product.
For aerospace, defense, and medical device customers, documented inspection isn't optional. We build that documentation into every job so you're never chasing paperwork.
Every order. Every time. You don't have to ask. It's already in the box when the shipment arrives.
CMM verified. Documented. Ready to install.
