CNC Drilling

A reliable source for CNC Machining information and leading CNC Machining Companies.

CNC (computerized numerical control) drilling is an automated process that involves rotating cutting tools to produce round holes on a stationary workpiece. This drilling is carried out to accommodate the screws and bolts needed later to hold objects together and finish the production process of various items. Read More…

CNC Drilling CNC drilling employs computer automated machines to bore precision threads or holes into surfaces of variable material composition and thickness. An acronym for computer numerical control, this particular type of drilling utilizes advanced computer software to complete processing.

How Does CNC Drilling Work?

The CNC drilling process uses a spindle that secures the drill bits, chucks, and other moving parts in the mechanism. A computer control panel is used to activate and operate the machine. A CAD (computer-aided design) or CAM (computer-aided manufacturing) file type contains the drill settings like the speed, rate of feed, spindle positions, required diameters, and drilling depth.

After the manufacturing process, these parts are inspected for compliance, and any required changes are made as needed. Equipment maintenance and repairs are advised after every use. Furthermore, users should inspect drill bits for cracks and changes.

Types of CNC Drilling Machines

The types of CNC drilling machines include:

Upright drill press

The upright drill press is a CNC drill featuring a geared spindle drive head, and it is mainly designed for heavy, large parts. Unlike most other drills, It is commonly known for feeding a workpiece to the cutting tool and not vice versa.

Upright Drill Press

Radial arm drill press

This CNC drilling machine adopts the basic mechanism of setting a moving spindle on a stationary workpiece. The wheel head provides a cutting tool that can perform multiple operations on the parts presented in different sizes and forms.

Radial Arm Drill Press

Gang drilling machine

A gang drilling machine has numerous work heads. The work heads are positioned on a work table where the part is mounted or fixed. It facilitates the simultaneous processing of what would otherwise require numerous successive operations.

Gang Drilling Machine

Multiple-spindle drilling machine

As the name indicates, the multiple-spindle drilling machine has multiple spindles connected to a single work head. These spindles are all fed to the workpiece simultaneously. These machines are utilized in the production of components requiring many closely-packed holes.

Multiple-Spindle Drilling Machine

Micro drill press

A micro drill press is a small and very accurate drilling machine. It has very small chucks and is typically used when dealing with small parts and shaping them.

Micro Drill Press

Turret-type drill

The turret-type drill has numerous work heads that are mounted on a turret. This configuration allows for quickly changing the required cutting or drilling tools and positioning over the workpieces.

Applications of CNC Drilling

Metal fabrication

CNC drilling is mainly used in metal fabrication processes such as those required for the automobile or aerospace industries. Metal piercings, perforations, and designs are all more- easily made by CNC drills.

Additionally, many metal (and other) products require precise drilling that only CNC drills may deliver within a specific timeframe. Such products include wheel hubs, gear blanks, and custom-designed shafts.

Wood manufacturing

Wood manufacturing is another important application for CNC drilling. The drill is used to shape wooden planks and to do piercings and decorations.

Electronic components

Some highly-precise CNC drilling machines are used to shape microscopic parts with great production rates. With computer programs, the drill can accurately drill without damaging fragile components.

Electrical industry

Some electric components require accurate drilling to be used with electric power transmission. Complex circuit breakers and transformers are typical examples of such items.

Plastic manufacturing

CNC drilling machines are also used to design intricate patterns used in decorative packaging and displays.

Advantages of CNC Drilling

Higher accuracy and precision

CNC technology-based drills can make original designs with very tight edges without wasting resources.

CNC Drilling

Versatility

CNC drilling is an operation that can be employed with numerous materials ranging from various metals to weaker materials like plastics and nylon. Additionally, numerous drill bits exist to produce various hole types and patterns.

Fewer sub-quality products

Correctly set-up CNC mills are less prone to faults, leading to consistency and uniformity during the production of large-scale orders.

Compatibility with other machining operations

Traditional drilling requires frequent adjustments of various mills and routers and is often performed independently of one another and other manufacturing processes. CNC drilling allows for changes to be performed as a single equipment unit and simultaneously with other procedures of material shaping.
