Automated machinery appraisals are a common part of equipment and machinery appraisals. Computer Numeric Controlled (CNC), automated machinery is found on asset lists at both large manufacturing operations and small custom machining shops. These machines can be valued for collateral lending, buy/sell agreements, and family law. It is important to appreciate the versatility of CNC machines and how that versatility weighs value.
Many CNC machine factory can be used in many different applications. This results in a large market nationally and internationally. It may also translate into higher overall value depending on the equipment appraisal value. However, other CNC machines are rare, which can lead to a lower market and potentially lower value depending on what value is used. While non-CNC machinery that is used in similar applications might have a wider market, it does not generally have the same value as CNC machines.
The tooling that comes with any CNC machine tool is an integral part. The tooling includes working or manufacturing tools such as cutting and patterning aids like dies, fixtures or gauges. A lot of CNC equipment comes with a lot of tooling. Tooling is usually valued together rather than separately depending on the purpose of the appraisal, the value being sought, and whether the tooling can be transferred.
CNC machines are also known as CNC machine centers. They can produce the same work piece using different machines depending on the size of the bar stock. Multiple axes are available on many CNC machining centers, which allow users to mass-produce identical outputs at high precision. These machines can perform many operations on one piece of work and multiple machines can produce the exact same part within four millimeters of an inch tolerance.
This article is primarily about bar-feed CNC machines. Bar feed CNC machining centers can perform multiple operations on a single work piece (milling and drilling, shaping, etc.). The number of axes and the type of tooling installed on the machine will determine the capabilities. If the machine is equipped with a sub-spindle (as some do), you can perform more operations on one piece of the work piece at a time while the main spindle is spinning. A bar loader attachment can also be added to all bar feed CNC centers. The machine can be loaded by bar stock with a bar loader so it can run for long periods of time without the need for operator assistance (e.g., all weekend).
What exactly is a CNC machine? A CNC machine works by taking a piece of steel stock, feeding it into the machine at the exact place it needs, performing the programed operations using the tooling, cutting the work piece, then removing it from the machine. Next, the machine measures another section from the same bar stock and repeats this process until it creates another work piece. The machine can automatically pull a new bar stock from the bar loader if it has a bar lifter. It’s amazing.
However, the CNC machine’s manufacturing process creates a lot of friction and debris. If not managed, this could cause damage to the work piece as well as the machine. Heat (caused by friction) can cause damage in two ways. Heat can cause the metal to expand, which is unacceptable when working within four-millionths inch tolerance. And heat can also break down lubricants in the process, making them less efficient. Other debris, such as chips and curls, can cause damage.

The CNC machine can be programmed to apply the lubricant at a specific time, place, and flow to manage friction-created heat and debris during work piece processing. During the production process, lubricants are applied to the work piece. This cools the process and collects any debris. The used lubricant and debris are then transferred to a holding tank, where it is filtered and chilled in the chiller. The CNC machine’s chip conveyor moves debris from the filter area into a separate location. After cooling, the lubricant can be re-used in work piece production.
