Camshaft Grinding Machine

-- Steady & Reliable Manufacturer --

Intro

The camshaft grinding machine is a dedicated CNC machine for grinding cam lobe profiles and journals on engine camshafts, using CNC-controlled non-circular interpolation to follow each lobe's specific profile rather than the simple round path used for a journal.

Core Capability

CNC axes coordinate spindle rotation with infeed to trace the lobe's base circle, flank and nose geometry from a stored profile, while journals are ground in a separate fixed-center mode on the same machine, so a full camshaft can be finished without moving to a second machine for journals.

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.

Lobe profile data is loaded as a customer-supplied cam lift table or master-cam reference; share your camshaft drawing or lift data and we will confirm program compatibility before ordering.

Workpiece Range

Grinds automotive, motorcycle and small diesel engine camshafts from 300–1200mm long with up to 16–20 lobes and journals per shaft, in chilled cast iron or hardened alloy steel. Journal diameters typically run Ø20–60mm, with lobe lift up to about 12mm depending on the cam profile.

Profile Accuracy

Lobe profile accuracy is verified against the stored lift data rather than a simple diameter check, since a cam's function depends on the exact shape of its flank and nose, not just an average size — journal roundness is held to ≤0.002mm using the same fixed-center grinding mode as a standard cylindrical operation.

Core Functions

  • CNC non-circular interpolation to trace each lobe's stored profile
  • Fixed-center journal grinding mode on the same machine
  • Automatic wheel dressing to maintain lobe profile accuracy over a batch
  • Optional in-process gauge for lobe lift and journal diameter verification
  • Steady rest support for longer camshafts during grinding

Quality Control

  • Lobe profile verified against the customer's stored lift data or master cam
  • Journal roundness and diameter checked using the same standards as cylindrical grinding
  • Factory acceptance test (FAT) run on the customer's own camshaft sample
  • Wheel balance and spindle runout verification before shipment
  • ISO9001-certified manufacturing with documented warranty terms

FAQ

  • Q: How is a camshaft grinder different from a crankshaft grinder?
  • A: A camshaft grinder traces each lobe's non-circular profile using CNC interpolation, while a crankshaft grinder uses an orbital head to grind round but off-center crankpins — the two follow fundamentally different tool paths for different part geometries.
  • Q: Can it handle a custom or aftermarket cam profile, not just a standard OEM design?
  • A: Yes, as long as lift data or a master cam reference is provided, the CNC program can be built around a custom profile for performance or aftermarket camshaft production.
  • Q: How many lobes and journals can it grind on one camshaft?
  • A: Standard configuration covers up to 16–20 lobes and journals per shaft; share your camshaft drawing to confirm compatibility with your specific design.
  • Q: What tolerance can be expected on lobe profile and journal diameter?
  • A: Journal roundness typically holds to ≤0.002mm; lobe profile accuracy is verified against your stored lift data rather than a single diameter tolerance, since the profile shape itself is what's being controlled.
  • Q: What is the typical lead time?
  • A: Standard configurations usually ship in 80–100 days; custom profile programming or extended length configurations may extend this to 100–130 days.

Equipment Configuration

  • Precision C-axis spindle with high-resolution rotary encoder for profile tracing
  • Servo-driven infeed axis coordinated with spindle rotation for the lobe path
  • Automatic wheel dressing unit for both lobe and journal grinding modes
  • Choice of Fanuc or Siemens CNC control
  • Steady rests positioned per camshaft length and lobe layout
