CNC Grinder

-- Steady & Reliable Manufacturer --

Intro

CNC grinder groups together every CNC-controlled grinding machine we build, including CNC cylindrical grinders for shafts and rollers and CNC crankshaft grinders for engine crankshafts. All of them replace manual handwheel infeed with programmable axes, so the same buyer can standardize on one control platform across different part types.

Core Capability

Each machine in this line combines CNC interpolation with automatic wheel dressing and an optional in-process gauge, so cycle-to-cycle diameter variation is controlled by the program and feedback loop rather than by an operator's dial reading. Buyers running multiple part types can keep one CNC brand and training standard across several machines.

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.

Specification Range

Machine TypeTypical Diameter RangeAxesPositioning AccuracyControl
CNC cylindrical grinderØ10–500mm2–4 axes±0.002mmFanuc / Siemens / GSK
CNC crankshaft grinderØ30–150mm (journal/pin)4–6 axes±0.002mmSiemens 828D / Fanuc 0i-F

Axis count and accuracy above are baseline figures; exact configuration depends on workpiece length, journal/pin geometry and whether an in-process gauge is included.

Processing Scope

Across the CNC line, machines handle straight, taper and profile external/internal grinding on general shafts and rollers, plus orbital pin and journal grinding on engine crankshafts. Achievable tolerance is IT5–IT6 with roundness typically ≤0.002–0.003mm, depending on machine type and part rigidity.

Batch Suitability

These machines are built for repeat production rather than one-off toolroom work — the CNC program and gauge feedback pay off most when the same part or part family runs across many pieces. For highly varied, low-volume work, a conventional grinder is usually the more economical choice.

Core Functions

  • CNC interpolated infeed for straight, taper, profile or orbital grinding paths
  • Automatic wheel dressing cycle triggered by part count or wheel condition
  • Optional in-process gauge for closed-loop diameter correction during the cycle
  • Stored program library for fast changeover between part numbers
  • Cycle and dimensional logging to support SPC review across a batch
  • Interlocked enclosures with coolant mist extraction for continuous operation

Quality Control

  • Factory acceptance test (FAT) available on the customer's own sample part
  • In-process gauge calibration checked against CMM measurement before shipment
  • Wheel balance and spindle runout verification on every machine
  • Process capability (Cpk) data available on request for critical dimensions
  • ISO9001-certified manufacturing with documented warranty terms

FAQ

  • Q: What does "CNC grinder" cover in your product range?
  • A: It covers all CNC-controlled grinding machines we build, mainly CNC cylindrical grinders for shafts/rollers and CNC crankshaft grinders for engine crankshafts — the shared trait is programmable axes and automatic cycles rather than manual dial infeed.
  • Q: Can I standardize on one CNC control brand across different machine types?
  • A: Yes, Fanuc, Siemens and GSK control options are available across most models in this line, which simplifies operator training if you are buying more than one machine type.
  • Q: Is a CNC grinder worth it for smaller production runs?
  • A: It depends on repeat volume — CNC pays off when the same part runs many times; for highly varied, low-volume toolroom work, a conventional grinder is usually more cost-effective.
  • Q: Can these machines connect to our MES or data collection system?
  • A: Yes, the CNC controls are PLC-networked and can be configured for MES connectivity; share your data protocol and we will confirm compatibility.
  • Q: What is the usual lead time across this CNC range?
  • A: Most standard CNC configurations ship in 60–90 days; machines with in-process gauging or automation options may need 90–120 days.

Equipment Configuration

  • Choice of Fanuc, Siemens or GSK CNC control across the line
  • Servo-driven axes on precision linear guideways or hardened box ways
  • Direct-drive or belt-drive wheel-spindle motor depending on model
  • Optional integrated in-process gauge wired into the CNC control loop
  • PLC networking ready for MES or production-data collection systems

Where It Is Used

  • Automotive and diesel engine component manufacturing
  • Bearing, hydraulic and pump/motor shaft production
  • Crankshaft OEM and Tier-1 production plants
  • General machinery manufacturers moving from manual to CNC processes
  • Contract machining suppliers serving multiple end-use industries

Automation Options

  • Standardized control brand selection across multiple CNC machines for one buyer
  • Robot or gantry loading integration for unattended cycles
  • MES/production-data connectivity for output tracking and SPC reporting
  • Custom program development based on the buyer's own part drawings
  • In-process gauge upgrade path for buyers starting on a base CNC configuration
