CNC Deep Hole Machine Tools for UK Manufacturers

Process selection for long bores, small-diameter high L/D holes, precision sleeves and hydraulic cylinder tubes—based on the drawing and acceptance method.

Send Your Drawing for a Process Proposal Compare the Five Processes

Process selection

Compare five deep-hole machining routes

The process route is selected around blank condition, stock removal, geometry, finish, output and the agreed inspection method.

CNC Deep Hole Drilling & Boring

Typical planning range: bores about 20–500 mm and depth up to about 16,000 mm, depending on the selected model and process route.

Review this process

CNC Gun Drilling

Typical planning range: about 3–40 mm and up to about 3,000 mm. Material, L/D, coolant and chip removal must be reviewed.

Review this process

CNC Deep Hole Honing

Typical planning range: about 25–500 mm and up to about 8,000 mm. Final tolerance and finish depend on the pre-bore.

Review this process

CNC Skiving & Roller Burnishing

Typical planning range: ID about 40–500 mm and length up to about 8,000 mm for a suitable tube, allowance and process window.

Multi-Station Gun Drilling

A gun-drilling cell for repeat part families. Station count follows the workpiece, takt, loading, coolant, tool and inspection plan.

Frequently asked questions

Before requesting a machine configuration

Which process should we use for a deep bore?

Gun drilling is normally evaluated for smaller high L/D holes; drilling and boring or BTA for larger diameters and stock removal; honing or SRB for final size and finish. The drawing and pre-bore control the route.

Can the machine be configured around an existing production cell?

The proposal can review loading, fixtures, coolant, filtration, chip handling, gauging and data interfaces. Compatibility must be confirmed from the actual cell specification.

How are tolerance, straightness and roughness accepted?

The workpiece, measuring method, instruments, sampling plan and limits are agreed in the signed technical specification before factory acceptance.

What information is required for a proposal?

Provide the drawing, material and hardness, diameter, depth, allowance, pre-bore condition, tolerances, roughness, quantity and target takt time.

Are UK conformity documents included?

Required conformity, electrical, guarding and documentation standards must be listed in the enquiry and verified for the quoted configuration.
