Shafts, pins, and rods
Review of cylindrical components with external diameters, shoulders, grooves, threads, or other drawing-defined features.
CENTERLESS GRINDING —
Centerless grinding for drawing-defined cylindrical components.
Kondak integrates centerless grinding into the manufacture of shafts, pins, rods, bushings, and other cylindrical components when a drawing requires external-diameter finishing and dimensional control.

WHEN IT FITS —
For cylindrical parts requiring a grinding step after machining.
In centerless grinding, the workpiece is supported without being held between centers while its external diameter is finished. Process selection depends on geometry, stock allowance, material, heat-treatment condition, tolerance, roughness, and quantity.
Integrated machining and finishing
Integration with CNC turning, Swiss-type lathes, threading, and inspection to reduce supplier interfaces when the route is approved.
Recurring industrial batches
Review of repeatability, control, documentation, and delivery frequency for components supplied in order-defined batches.

PUBLISHED CAPABILITY —
Process, inspection, and documentation defined from the current drawing.
Kondak publishes centerless grinding among its operations. Diameter, length, material, tolerance, roughness, stock allowance, and volume do not form a universal envelope and must be confirmed for each part.
01
Centerless grinding for cylindrical-component finishing after technical review
02
Integration with CNC turning and Swiss-type automatic lathes when required by the process route
03
Review of diameter, length, stock allowance, geometry, and material condition before quoting
04
Control of specified characteristics using CMM, roughness tester, profile projector, and applicable instruments
05
MES production records and traceability or dimensional reports when applicable
06
Coordination of heat and surface treatments through approved suppliers when included in the approved order
EVIDENCE —
Cylindrical components, combined operations, and dimensional control.
The images show parts and resources already published by Kondak; they do not represent a universal grinding envelope. Feasibility depends on the drawing, material, tolerance, finish, and batch.
Shafts and cylindrical parts
Turned geometries that may require additional finishing on drawing-defined external diameters.
Combined operations
Turning, threading, grinding, and complementary operations reviewed in one process route.
Dimensional inspection
Control of drawing-defined characteristics and documentation when required by the order.
FOR RFQ —
What to send for a centerless-grinding review.
A complete technical package helps determine whether the operation is suitable and prevents assumptions about machine limits, stock allowance, inspection, or material condition.
01
Current-revision 2D drawing, 3D model, physical sample, or functional specification
02
Material, standard, hardness, supply condition, and heat or surface treatments
03
Diameters, lengths, shoulders, grooves, threads, stock allowance, and areas that must not be ground
04
Tolerances, roughness, and form requirements such as roundness, cylindricity, and straightness
05
Initial quantity, recurring batch, delivery frequency, and expected lead time
06
Inspection plan, certificates, traceability, and required dimensional reports
PROCUREMENT QUESTIONS —
Common questions about centerless grinding.
Does Kondak provide centerless grinding?
Yes. Centerless grinding is listed among Kondak's published operations for finishing cylindrical components. Feasibility is confirmed after reviewing the drawing, material, stock allowance, tolerance, roughness, and quantity.
Which parts can be reviewed for centerless grinding?
Shafts, pins, rods, bushings, and other cylindrical components can be reviewed. The complete geometry, including shoulders, grooves, threads, and unground sections, determines the possible process route.
What are the diameter, length, and tolerance limits?
Kondak does not publish a universal centerless-grinding limit. Diameter, length, tolerance, roughness, material, heat-treatment condition, and batch are confirmed against the specific drawing revision.
Can grinding be purchased together with turning?
Yes, when the technical review approves the route. Kondak can integrate turning, threading, centerless grinding, inspection, and applicable complementary processes within the same supply.
