CNC Deep Hole Boring Machine Manufacturer

Guanghe configures deep hole boring machines around the existing bore, stock allowance, final diameter, straightness, surface requirement, workpiece support and inspection method.

Selection boundary: A deep hole boring machine works from an existing bore. It is not presented as a substitute for gun drilling, and it is separated from machines that must perform both initial drilling and boring.

Process Selection Before Machine Selection

Existing bore required

Confirm whether the starting bore is drilled, cast, forged or thermally distorted, and record the minimum available allowance.

Correction objective

Define whether the main purpose is diameter enlargement, straightness correction, geometry recovery, surface improvement or preparation for honing/SRB.

Push or pull boring

The tooling direction and support arrangement are selected from the part, bore condition, chip flow, accuracy and machine layout.

Workpiece Parameter Matrix

Required inputWhy it changes the machine proposal
Starting bore conditionSolid, pre-drilled, cast or forged bores require different drilling, boring and finishing routes.
Diameter, depth and L/D ratioDefines process family, spindle/tool support, coolant system and chip evacuation.
Material and hardnessControls tool grade, cutting data, chip formation and expected tool life.
Diameter tolerance, straightness and positionDetermines whether drilling alone is sufficient or boring/honing is required.
Surface roughness and stock allowanceDetermines the finishing process and number of passes.
Part envelope, weight and annual volumeDefines bed length, clamping, single/multi-station layout and automation level.

Typical Workpieces and Industries

Typical evaluations include hydraulic cylinder components, long sleeves, heavy-machine parts, energy equipment parts and repaired or semi-finished bores. Material, heat treatment, part weight and clamping surfaces must be confirmed before the process is selected.

Single-Station, Multi-Station and Automation

Single-station equipment is appropriate for larger parts, mixed batches or processes requiring independent adjustment. Multi-station equipment is considered for repeat part families when fixture repeatability, coolant capacity, chip control and inspection can be maintained. Automation is specified only after the base process and acceptance method are agreed.

Standard and Optional Configuration

Planning groupItems to confirm
Base machineBed, spindle/headstock arrangement, feed system, guards, coolant circulation and chip collection.
Tool and workpiece supportGuide bushes, steady rests, fixtures, tool supports and part rotation according to the workpiece.
Controls and monitoringCNC system, alarms, pressure/flow monitoring, tool-life monitoring and data interfaces.
OptionsAutomatic loading, indexing, additional stations, filtration upgrades, oil cooling and inspection integration where the process requires them.

Delivery, Acceptance, Installation and Training

Boring acceptance should define the datum, measurement sections, minimum/maximum stock, final size, straightness, roundness, cylindricity where required, roughness and the named measuring tools.

The proposal should state the drawing revision, test piece, material, tool, coolant, measuring instrument, sample size and acceptance limits. Delivery, installation, operator training, maintenance training and after-sales boundaries must be written into the commercial and technical documents.
