Few material decisions spark as much debate as titanium vs aluminum. Both metals are light, both machine well, and both appear everywhere from drones to surgical tools. Yet they behave very differently in service, in the spindle, and on the invoice. This comparison walks through the properties buyers actually pay

A single mismatched fastener can halt an assembly line, strip a housing, or trigger a field repair. The UNC vs metric threads question sits at the root of many such failures. One system measures diameter in inches and pitch in threads per inch. The other expresses both values in millimeters.

CAD files for CNC machining are the foundation of every accurate quote and every good part. A machine shop turns your geometry into toolpaths, fixtures, and inspection plans. Everything downstream inherits the quality of what you send. A clean export can speed a quote by hours or days, while a

GD&T basics belong in every mechanical buyer’s toolkit. Geometric Dimensioning and Tolerancing, standardized under ASME Y14.5, describes how parts must fit and function, not just how big they are. A plain ± tolerance on every dimension looks simple, yet it can hide gaps, misalignment, and assembly failures. This guide walks

Every machined pocket carries an inside corner radius, and that radius comes straight from the cutting tool. An end mill is a cylinder, so it can only trace a matching arc where two walls meet. If your drawing shows a sharp 90-degree internal corner, the machine physically cannot produce it.
