Our machinists check critical dimensions during production using digital calipers and micrometers. For tighter specs, we verify on our coordinate measuring machine. This catches any drift before moving to the next operation. No filing, no forcing, no rework needed. Just a clean assembly that gets your equipment running fast.

We Machine Spare Parts That Fit Your Equipment Perfectly
Fit starts with accurate measurements and proper setup. You send us drawings, CAD files, or the worn part itself. Our engineers review every dimension before programming toolpaths.
We machine on Haas VF-series vertical machining centers and DMG Mori multi-axis machines. These hold tolerances within 0.01mm across the entire part. Positioning accuracy stays consistent, incluso en geometrías complejas.
Tops Works with Metals Built for Heavy-Duty Performance
We work with brass, acero carbono, aleaciones de aluminio, and stainless steel grades. Different metals react differently to the cutter. For each material, we change the speed, alimentar, y herramientas.
Aluminum machines quickly and stays light for moving parts. At high RPM, we use carbide end mills. To keep stainless steel from hardening, you need to use slower speeds and tools that are coated. Flood coolant keeps things cool and makes tools last longer.

For heavy-duty uses in automation and machinery, carbon steel is strong. Brass is easy to work with and protects sliding parts from wear. We choose the material based on the needs of your industry and how you work.
Our CNC machines keep the quality of the surface finish the same on all metals. We can provide you with the right material and precise machining, whether you need corrosion resistance for medical parts or strength for automation equipment.

We Match OEM Specifications Down to the Micron
OEM parts work because they are made to fit perfectly. We can make that level of accuracy again by using your original drawings or by reverse engineering parts from samples.
Using precise inspection tools, our engineering team measures the original part. We take pictures of the geometry, hole spacing, thread specs, and surface profiles. Our Mastercam software uses this data to make accurate toolpaths.

We do first-article inspections during production to make sure all important features are there. Thread gauges check the pitch and fit class. Pin gauges measure the size of holes. We check each measurement against your specification sheet.
Parts that aren’t within tolerance don’t leave our shop. We change the tool offsets and re-machine if the dimensions change. That makes sure that your replacement part works just like the original OEM part.
Our Custom Machining Replaces Hard-to-Find Spare Parts
Discontinued parts shut down production lines. It costs you money to wait months for replacements. We make custom spare parts for your equipment so it keeps working. Please send us the worn-out part or your technical drawings. Our engineers check the design and measure important dimensions.
We find surfaces that wear down quickly, areas that can hold a lot of weight, and features that need to be very precise. We put your specifications into our CAM software and set up the toolpaths. Our 4-axis and 5-axis CNC machines can cut complicated shapes in one go.
No realigning means no mistakes in alignment. Every feature stays true. We don’t need a lot of orders. Do you need five parts? One piece? We’ll do it with a machine. Our team quickly sets up your job and starts cutting within a few days. You get functional spare parts quickly, not excuses about how long it will take.

We Add Threads, Agujeros, and Features with Tight Tolerances
Features tell spare parts how to fit together and work. We make threads, counterbores, chaveteros, and mounting holes exactly to your specifications. Each feature is programmed with controlled toolpaths so that there is no chatter.
Our CNC centers make clean, precise threads when they do thread milling. We use rigid tapping for holes that go all the way through and holes that don’t. The thread pitch stays the same along the whole length. This makes sure that the mating parts fit together correctly.
Holes are drilled and then reamed to the right size. We use peck drilling to make deep holes because it clears chips and stops tools from breaking. Pilot tools are used to cut counterbores and countersinks so that they line up perfectly.
Sharp end mills are used to cut keyways, tragamonedas, y bolsillos. We keep the width and depth within 0.02mm. The surface finish on the inside features stays smooth to prevent stress concentrations and wear down.
Every extra part has a job to do in your assembly. We machine them correctly so that your spare parts fit easily and work well when they’re under load.

Tops Inspects Every Spare Part Before It Leaves Our Shop
Quality control is done all the time during production, not just at the end. After each operation, our machinists use calibrated measuring tools to check the dimensions. This catches problems early on, before they get worse.

Go/no-go gauges, pin gauges, and micrometers are used to check critical dimensions. We use our CMM to check many points on complicated parts. The measurement data shows that every feature meets the requirements of your drawing.
When asked, we check the surface finish by looking at it and using profilometers. All edges are free of burrs. To avoid problems with assembly and keep operators safe, sharp corners are deburred by hand.
We use pitch gauges and thread ring gauges to check the quality of the thread. We check the size, redondez, and straightness of the holes. If any part fails inspection, it is either fixed or thrown away right away.
This process is backed by our ISO 9001 proceso de dar un título. We keep records of inspections and give measurement reports when asked. You get parts that work the first time.
Our CNC Spare Parts Outlast Standard Replacements
Durability comes from material selection and machining precision. We cut parts from solid bar stock, not castings or poor-grade materials. This eliminates internal voids and weak points that cause premature failure.
Machined surfaces are stronger than molded or stamped alternatives. Our cutting tools create work-hardened surfaces that resist wear. Controlled feeds and sharp tooling prevent micro-tears that lead to crack initiation.

We machine features with proper radii and transitions. Sharp internal corners create stress risers. We blend fillets and chamfers to distribute loads evenly across the component.
Heat from machining gets managed with coolant and proper cutting parameters. This prevents material property changes that weaken parts. The result is a spare part that maintains strength and dimensional stability.
Where plastic parts crack and cast parts break, our machined spare parts keep running. You get longer service life and fewer replacements over your equipment’s lifetime.
