Grinding Machine for Automotive Industry

-- Steady & Reliable Manufacturer --

Intro

This page maps the automotive components a powertrain or chassis plant typically grinds — crankshafts, camshafts, transmission and axle shafts, wheel-bearing rings, injector parts and EV motor shafts — to the grinding machine in our range built for each one.

Core Capability

Automotive buyers usually source several grinding machines for one program, so the common requirements across the range matter: takt-time-driven cycles, in-process gauging, cycle data logging for customer audits, and loader interfaces for automated lines.

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.

EV traction motor shafts are covered by the automotive shaft grinder in the third row. Send your part list and annual volumes and we will propose the machine mix and count.

Processing Scope Across the Range

The machines above cover diameters from Ø3mm to Ø300mm and crankshafts and camshafts up to 1200mm long, in case-hardened and through-hardened steel, forged steel and ductile iron. Tolerance runs from IT5 on general shafts to roundness ≤0.001mm on precision parts and bearing rings.

Production Context

Automotive grinding is judged on process stability over shifts, not a single first-off part. The machines in this range are therefore configured with closed-loop gauging and data logging so drift is caught and compensated before parts leave tolerance.

Core Functions Shared Across the Range

  • Closed-loop in-process gauging with automatic wheel wear compensation
  • Automatic wheel dressing triggered by part count or measured condition
  • Cycle and dimensional data logging for customer quality audits
  • Program libraries for fast changeover between part variants
  • Robot or gantry loader interface for automated lines

Quality Control

  • Process capability data collected from in-process gauges during production
  • Factory acceptance test on the customer's own sample parts
  • Gauge calibration cross-checked against CMM measurement before shipment
  • Manufacturing process aligned with common automotive supplier quality practices
  • ISO9001-certified manufacturing with documented warranty terms

FAQ

  • Q: Can you supply several machine types for one automotive program?
  • A: Yes, the range above covers crankshafts, camshafts, shafts, bearing rings and precision pins, and we can propose a standardized control and loader interface across them.
  • Q: Can the machines provide the data our OEM customer audits?
  • A: Cycle and dimensional data logging is built in, and the export format can be adapted to your customer's reporting requirements.
  • Q: Do you support EV components?
  • A: Yes, EV traction motor and reducer shafts within the stated diameter and length range are ground on the same automotive shaft platform as traditional driveline shafts.
  • Q: How do I work out how many machines I need?
  • A: It depends on takt time, number of features per part and stock removal; send annual volume and part drawings and we will calculate the machine count.
  • Q: What is the general lead time?
  • A: Shaft and precision-part grinders typically ship in 60–90 days, while crankshaft and camshaft machines take 80–130 days; multi-machine lines with automation take longer.

Equipment Configuration Overview

  • Siemens or Fanuc CNC control, standardized across machine types where possible
