CNC Grinding Machine for Shaft Grinding

-- Steady & Reliable Manufacturer --

Intro

This page brings together every machine in our range built for shaft grinding — general industrial shaft CNC grinders, crankshaft grinders, precision small-shaft grinders and heavy-duty large-shaft machines — so buyers researching shaft grinding broadly can compare options by shaft type rather than starting from one model page.

Core Capability

Whatever your shaft looks like — straight, multi-diameter step, eccentric crankshaft, small precision pin or oversized heavy shaft — the shared requirement is holding roundness and positional accuracy along its length. The right machine mainly depends on shaft geometry and production volume rather than diameter alone.

Premium Materials and Components

Materials and components are the most critical elements to affect the performance of the equipment.

We use high-quality raw materials and branded components to ensure that our high-performance machines have a long service life and short downtime.

  • External grinding wheel chuck
  • Flat grinding wheel chuck
  • Φ 400 or Φ 600 balance frame
  • M7130-5006 front bearing
  • Rapid advance and retreat cylinder
  • Pressure valve plate assembly
  • Feed box assembly
  • Overflow valve
  • Table control box
  • Grinding head box
  • Control panel assembly
Design for High Performance

The performance of a machine is the result of the combined effect of all its components.

Our technical team consists of experienced engineers and technicians who are not only proficient in the operation and maintenance of grinders, but also have a deep understanding of material properties and processing technology. This enables us to provide customers with customized solutions to meet their specific processing needs.

By deeply studying the design and manufacturing process of precision grinding machines and paying great attention to configuration and construction from the beginning, our R&D team is able to provide high-performance equipment.

Shaft Type Selection Guide

Shaft TypeRecommended MachineDiameter RangeBest Fit
Straight / multi-diameter step shaftCNC Cylindrical Grinding Machine for ShaftsØ10–300mmMotor, pump, gearbox shafts
Eccentric crankshaftCrankshaft Grinder rangeØ30–500mmEngine and compressor crankshafts
Small precision shaft/pinCNC Cylindrical Grinder for Precision PartsØ3–150mmInstrument, gauge and medical shafts
Oversized heavy shaftCylindrical Grinding Machine (heavy-duty)Ø200–1250mmWind turbine, mill and heavy machinery shafts

Send your shaft drawing and expected volume, and we will point you to the matching machine and configuration rather than leaving you to guess between similar-sounding product names.

Processing Scope Across Shaft Types

Across the range, shaft grinding machines cover straight, taper, step-diameter and eccentric geometries from Ø3mm up to Ø1250mm, in hardened steel, forged steel and alloy materials, with tolerance from IT4 precision work down to IT6–IT7 general industrial work depending on the tier selected.

Choosing by Geometry and Volume

Straight and step shafts are usually the most flexible starting point; eccentric crankshafts need a dedicated orbital work-head; very small or very large shafts benefit from a tier built specifically around that size range rather than pushing a mid-range machine outside its comfortable capacity.

Core Functions Shared Across the Range

  • CNC-programmed indexing between multiple diameters on straight and step shafts
  • Orbital/eccentric work-head specifically for crankshaft-type geometry
  • Optional in-process gauge feedback across most tiers for closed-loop size control
  • Steady rest support scaled to shaft length and diameter for each tier
  • Stored programs per shaft part number for changeover between different jobs

Quality Control

  • Tier-appropriate testing: CMM audit and in-process gauge calibration on CNC tiers, dial-gauge and trial-grind verification on manual/portable tiers
  • Wheel balance and spindle runout check across all tiers before shipment
  • Factory acceptance test available on the customer's own shaft sample
  • ISO9001-certified manufacturing with tier-specific warranty terms

FAQ

  • Q: How do I know which shaft grinding machine fits my part?
  • A: It mainly comes down to shaft geometry (straight/step versus eccentric) and size — send us your shaft drawing and expected volume and we will point you to the matching machine and configuration.
  • Q: Can one supplier really cover both straight shafts and crankshafts?
  • A: Yes, our range spans both, though the machines themselves are different — straight/step shafts use fixed-center CNC grinders while crankshafts need a dedicated orbital work-head.
  • Q: What if my shaft is unusually small or unusually large?
  • A: We have dedicated precision and heavy-duty tiers built specifically for those size ranges rather than pushing a mid-range machine outside its comfortable capacity — see the selection guide above.
  • Q: Do you offer help choosing between similar-sounding shaft grinding products?
  • A: Yes, this is exactly what this page and a quick drawing review are for — we will recommend the specific model rather than leaving you to compare product names alone.
  • Q: What is the general lead time across the shaft grinding range?
  • A: Precision and standard CNC shaft grinders typically ship in 60–90 days, crankshaft grinders in 60–120 days depending on tier, and heavy-duty machines in 120–180 days.

Equipment Configuration Overview

  • Precision linear guideways on CNC tiers for repeatable multi-diameter work
  • Orbital work-head and adaptor rings specifically for crankshaft-type machines
  • Reinforced bed and higher drive power on the heavy-duty large-shaft tier
  • Choice of Fanuc, Siemens or GSK CNC control standardized across most tiers

Where It Is Used

  • Electric motor, pump and gearbox shaft manufacturers
  • Automotive driveline and crankshaft producers
  • Wind-turbine and heavy machinery shaft manufacturers
  • Precision instrument and medical device shaft makers
  • Contract machining shops serving multiple shaft-type customers

Automation & Selection Support

  • Machine tier selection guided by your shaft geometry and production volume
  • Robot or gantry loading options available across most CNC tiers
  • Control brand standardization across multiple shaft-grinding machines for easier training
