Engineering Review & DFM, precision machined components, CNC parts, medial screws, lead screws, ball screws, mechanical part manufacturer - Johoty

1. Engineering Review & DFM：

Before producing precision machined components, Johoty conducts engineering reviews on customer drawings and 3D models. And material, key dimensions, tolerances, surface treatment, and final assembly requirements. Johoty suggests that customers clearly label functional dimensions, appearance, contact surfaces, threads, coating areas, and testing benchmarks. Then, we can identify various risks from potential processing, finishing, and batch consistency during the sample stage.

Material Preparation, precision machined components, CNC parts, medial screws, lead screws, ball screws, mechanical part manufacturer - Johoty 22

2. Material Preparation：

Johoty selects stainless steel, aluminum alloy, brass, copper alloy, carbon steel, engineering plastic, or customer specified materials. We always consider overall requirements for conductivity, corrosion resistance, lightweight, wear resistance, or medical instrument applications. Then, we will select material together with subsequent CNC machining, right finishing, and dimensional inspection.

3. CNC Turning & CNC Milling：

Johoty manufactures highly consistent precision machined components through CNC turning, CNC milling, and necessary composite machining. When producing barrels, barrel, threaded parts, and conductive contacts, we control the outer diameter and inner diameter. And end faces, chamfers, slots, and threads. For the shell, positioning block, and installation structural components, we focus on controlling the hole position and flatness. And the accumulated errors in verticality, assembly surface, and multi-faceted processing.

4. Deburring, Sandblasting & Polishing：

After CNC machining, Johoty will process deburring, sanding, sandblasting, polishing, or local appearance according to part function. We do not view surface treatment solely as making the parts look better. We need to control tactile sensation of contact surface, the assembly smoothness, surface condition before plating. And appearance consistency, and the subsequent cleaning effect.

Precision Cleaning, precision machined components, CNC parts, medial screws, lead screws, ball screws, mechanical part manufacturer - Johoty 22

5. Precision Cleaning：

Cleaning is a necessary step for precision machined components before electroplating, anodizing, passivation, coating, and final packaging. Johoty specifies that cleaning is used to remove processing oil, grinding residues, polishing dust, metal shavings, and surface contaminants. This will reduce poor coating, poor contact, corrosion, and packaging contamination.

6. Surface Finishing：

Johoty can provide electroplating, electrophoresis, anodizing, passivation, coating, sandblasting, polishing, and other surface treatment solutions. For conductive components, Johoty focuses on contact resistance and coating uniformity. For aluminum alloy parts, Johoty focuses on the corrosion resistance and appearance consistency after anodizing. For stainless steel parts, we focus on the cleanliness and corrosion resistance after passivation. For exterior components, we pay attention to color differences, scratches, fingerprints, and packaging protection.

Dimensional Inspection, precision machined components, CNC parts, medial screws, lead screws, ball screws, mechanical part manufacturer - Johoty 22

7. Dimensional Inspection：

Johoty will strictly inspect various key dimensions, including outer diameter, inner diameter, hole position, and length. And steps, threads, concentricity, flatness, perpendicularity, surface roughness, and key assembly dimensions. We can achieve testing accuracy of ±0.007mm according to the drawings, production line, and testing tolerance. Johoty always checks the part dimensions according to the drawings and controls the key dimensions. It is to ensure each workstations compliance with client’s tolerances.

Custom Gauges & Fit Verification, precision machined components, CNC parts, medial screws, lead screws, ball screws, mechanical part manufacturer - Johoty 22

8. Custom Gauges & Fit Verification:

Batch assembly parts, needle shafts, sleeves, connectors, and threaded components must be measured with the correct gauge. Johoty uses size gauges, thread gauges, hole gauges, outer diameter gauges, and assembly verification. The size gauge can verify whether the parts can stably enter the final assembly system.

Final Inspection & Documentation, precision machined components, CNC parts, medial screws, lead screws, ball screws, mechanical part manufacturer - Johoty 22

9. Final Inspection & Documentation:

Before shipment, Johoty confirms the dimensions, appearance, surface treatment, quantity, packaging, and labeling of precision machined components. For high demand projects, Johoty can provide FAI inspection, size reports, and material certification. And surface treatment certificate, coating thickness record or quality documents required by the customer.

Secure Packaging, precision machined components, CNC parts, medial screws, lead screws, ball screws, mechanical part manufacturer - Johoty 22

10. Secure Packaging:

Johoty attaches great importance to safe packaging, which is crucial for both delivery and customers. Precision parts are most afraid of scratches, deformation, and mixing during transportation. They are also afraid of pollution, coating friction, and pin bending. Johoty uses grid trays, anti-static bags, vacuum bags, foam, independent protection, label traceability, and reinforced export outer boxes.
