ID OD Grinding Machine

-- Steady & Reliable Manufacturer --

Intro

ID OD grinding machine refers to our precision internal-diameter/outer-diameter grinding equipment built for tubular and sleeve-type parts — bearing sleeves, hydraulic cylinder liners, precision bushings — where concentricity between the bore and outside diameter, and wall-thickness uniformity, are the main quality concerns.

Core Capability

Grinding the ID and OD in the same setup, on the same rotational axis, avoids the stack-up error that comes from clamping a thin-wall part twice on separate machines, keeping wall thickness even around the full circumference rather than just meeting each diameter's tolerance in isolation.

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.

Wall-thickness uniformity depends on the blank's starting concentricity as much as the machine, so a trial grind on your actual blank material is recommended before finalizing a tolerance commitment.

Workpiece Range

Covers bearing sleeves, hydraulic cylinder liners, precision bushings and similar tubular parts with outside diameter Ø10–200mm, bore Ø5–150mm and length up to 500mm, in hardened steel, bronze and cast iron. Thin-wall parts are supported with appropriate fixturing to avoid distortion during grinding.

Concentricity Focus

Because ID and OD are ground without re-clamping between the two operations, concentricity typically holds to ≤0.003mm and wall-thickness variation to ≤0.005mm, which matters for parts where an off-center bore would cause uneven wear or leakage once assembled.

Core Functions

  • Single-setup ID and OD grinding on a shared rotational axis to control concentricity
  • Thin-wall-compatible fixturing to minimize distortion during clamping and grinding
  • CNC-programmed infeed for both bore and outside-diameter passes (CNC version)
  • Optional in-process gauge for concentricity and wall-thickness verification
  • Automatic or manual wheel dressing depending on the control tier ordered

Quality Control

  • Concentricity between bore and outside diameter verified on every machine before shipment
  • Wall-thickness uniformity checked across a sample part where wall thickness is critical
  • Trial grind on the customer's actual blank material to confirm achievable tolerance
  • Roundness and surface-finish verification on both ID and OD
  • ISO9001-certified manufacturing with documented warranty terms

FAQ

  • Q: What is the advantage of grinding ID and OD on the same machine?
  • A: Grinding both without re-clamping the part avoids the stack-up error that comes from two separate setups, which is what keeps concentricity and wall-thickness uniformity tight rather than just meeting each diameter's tolerance individually.
  • Q: What concentricity and wall-thickness tolerance can be expected?
  • A: Typical results are concentricity ≤0.003mm and wall-thickness variation ≤0.005mm, though the starting concentricity of your blank also affects the final result — a trial grind is recommended to confirm.
  • Q: Can thin-wall parts be ground without distortion?
  • A: Yes, thin-wall-compatible chucks or mandrels are used to minimize clamping-induced distortion; share your part's wall thickness and material for a fixture recommendation.
  • Q: Should I choose the CNC or handwheel version?
  • A: The CNC version gives tighter batch-to-batch repeatability for production volumes; the handwheel version is a lower-cost option for smaller batches or toolroom-style work.
  • Q: What is the typical lead time?
  • A: Standard handwheel versions usually ship in 50–65 days; the CNC version typically takes 70–85 days.

Equipment Configuration

  • Shared-axis fixturing so ID and OD are ground without re-clamping the part

  • Interchangeable internal grinding spindle cartridges for different bore ranges
  • Choice of CNC (Fanuc/Siemens) or handwheel control
  • Optional in-process gauge for concentricity and wall-thickness feedback
