Precision Turning Hollow Cylinder Component

Tuoyuan Metal turns the precision turning hollow cylinder component on double-spindle lathes and machining centres under one roof in Jimo District, Qingdao. Boring, turning and secondary operations stay on one process sheet, so the bore and the outside diameter are measured against the same baseline. Send the drawing, and the quotation comes back with the process plan, a first-article report and a price for the volumes you expect to run. Material certificates and OEM packing travel with every shipment.

Product Features

These hollow cylindrical parts are used in assemblies where bore accuracy, wall thickness and alignment between internal and external surfaces are required.

1. Accurate Bore Control

The bore diameter is controlled to ±0.01mm as standard, with ±0.005mm available for selected features. Measurements are taken through the bore depth instead of checking only the entrance area, helping identify dimensional changes along the internal surface.

2. Stable Thin Wall Machining

Thin-wall parts are machined with suitable clamping methods to reduce deformation after releasing from the chuck. The process uses bored jaws where required, allowing the clamping force to distribute around the circumference.

3. Consistent Wall Thickness

Wall variation is controlled within 0.05mm and checked at multiple positions around the circumference. This inspection method helps identify off-centre bores before shipment.

Specifications

Applications

The hollow structure allows these machined parts to be used where internal passages, accurate fitting surfaces and stable dimensions are required. Precision Turning Hollow Cylinder Component is commonly used in mechanical assemblies that depend on bore alignment and controlled wall thickness.

● Hydraulic and pneumatic cylinder liners, sleeves and gland bodies

● Bearing housings and bushing blanks where shaft alignment is important

● Guide tubes and bushings used in automation and packaging equipment

● Sensor and instrument housings with precision internal surfaces

● Filter and separator bodies for medium flow applications

● Wear sleeves and spacers installed inside mechanical structures

Machining Process

The production sequence for Precision Turning Hollow Cylinder Component focuses on maintaining bore accuracy while controlling deformation during machining.

1. Rough Turning and Preparation

The raw material is prepared and rough machining removes excess material while leaving allowance for finishing operations.

2. Bore Finishing

Internal boring is completed according to required diameter, depth and tolerance. For deeper bores, machining parameters are adjusted according to the length-to-diameter ratio.

3. External Diameter Finishing

The outside diameter is finished after internal machining to maintain the relationship between the bore and outer surface.

4. Inspection Before Shipment

Dimensional records, material certificates and inspection data can be prepared according to project requirements.

Material Selection

Material selection depends on the working environment, corrosion requirements, machining conditions and final assembly requirements.

Quality Control

Inspection focuses on bore accuracy, roundness, concentricity and wall thickness. Each measurement is related to the machining requirements to ensure the finished parts meet the drawing specifications.

1. Bore Measurement

Internal micrometers, air gauges and bore comparators are used to check bore dimensions at different depths instead of measuring only the opening area.

2. Geometry Verification

Roundness, straightness and position accuracy are checked against the first-article measurement data. Bore and outside diameter concentricity can be controlled within 0.02mm.

3. Wall Thickness Inspection

Wall thickness is measured at multiple points around the circumference to identify uneven material distribution.

4. Production Records

Material certificates and measurement information are recorded according to the job number for production tracking.

FAQ

Q1: How thin a wall can you machine on a precision turning hollow cylinder component?

A: We machine walls down to about 1.0mm, and thinner on review where the part is short enough to stay rigid. Send the drawing and we will confirm the feasible wall with the process plan.

Q2: Can you hold the bore concentric with the outside diameter?

A: Yes. Boring and turning in one setup holds concentricity within 0.02mm, and tighter where the assembly needs it.

Q3: Do you hone or grind bores as well as turn them?

A: We turn and bore in house, and arrange honing or hard chrome for bores that need a mirror finish or wear resistance. Both are quoted with the part, not added afterwards.

Q4: What information do you need to quote?

A: A 2D or 3D drawing with material, bore tolerance and bore depth ratio. If you only have a sample, send it and we will measure it and return a drawing for your approval before quoting the precision turning hollow cylinder component.

Q5: Are surface finishing processes available?

A: Yes. Passivation, honing, hard chrome, anodising and plating processes can be arranged according to requirements.

Q6: How are finished parts inspected?

A: Parts are checked through dimensional measurement, bore inspection, roundness verification and production records.
