CNC Cylindrical Grinding Machine for Automotive Parts

-- Steady & Reliable Manufacturer --

Intro

This CNC cylindrical grinding machine is configured for automotive engine and transmission components — gear shafts, axle and CV-joint shafts, injector pins and EV motor shafts — where consistent takt time and documented process capability matter as much as raw grinding accuracy.

Core Capability

In-process gauging and cycle data logging are built around continuous multi-shift production rather than one-off jobs, so the same diameter is held within tolerance from the first part of a shift to the last, with the dimensional records automotive customers typically ask for during supplier qualification.

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.

Cycle time depends on stock removal and part geometry; share your part drawing and required takt time so we can confirm the cycle matches your assembly line rate.

Workpiece Range

Grinds gear shafts, axle and CV-joint shaft sections, injector pins and EV traction motor shafts from Ø10–120mm and up to 1200mm long, in case-hardened or through-hardened alloy steel. Tolerance is held at IT5 with roundness ≤0.002mm, matched to typical automotive drawing requirements.

Volume Production Fit

The machine is built for continuous multi-shift operation feeding an assembly or sub-assembly line, so cycle time consistency and in-process gauge feedback are prioritized over maximum flexibility for highly varied, low-volume parts.

Core Functions

  • Closed-loop in-process gauge for automatic diameter correction as the wheel wears
  • Automatic wheel dressing cycle timed to production part count
  • Cycle and dimensional data logging in a format suited to supplier quality documentation
  • Robot-ready loading interface for direct connection to an automated line
  • Stored programs per part number for fast changeover on mixed automotive lines
  • Barcode or RFID part tracking option for traceability requirements

Quality Control

  • Process capability (Cpk) data collection built into the standard control cycle
  • Factory acceptance test (FAT) run on the customer's own sample part
  • In-process gauge calibration cross-checked against CMM measurement
  • Manufacturing process aligned with common automotive supplier quality practices
  • ISO9001-certified manufacturing with documented warranty terms

FAQ

  • Q: Can this machine support the process capability (Cpk) data our automotive customer requires?
  • A: Yes, cycle and dimensional data logging is built into the standard control cycle, and the export format can be adapted to match your supplier quality documentation needs.
  • Q: Can it be integrated into an existing assembly or sub-assembly line?
  • A: Yes, a robot-ready loading interface and MES connectivity are available; share your line layout and takt time and we will confirm the integration approach.
  • Q: Does it handle EV motor shafts as well as traditional engine components?
  • A: Yes, the platform is not engine-specific — EV traction motor shafts within the stated diameter and length range can be programmed the same way as other automotive shaft parts.
  • Q: How long does changeover take between different automotive part numbers?
  • A: Once programs are saved, changeover is mainly a fixture swap plus program call, typically well under an hour depending on part similarity.
  • Q: What is the typical lead time?
  • A: Standard configurations usually ship in 65–80 days; added traceability or MES integration options may extend this to 90–110 days.

Equipment Configuration

  • Precision linear guideways for repeatable high-volume cycles
  • Direct-drive wheel-spindle motor for consistent finish shift after shift
