CNC Cylindrical Grinder for Precision Parts

-- Steady & Reliable Manufacturer --

Intro

This CNC cylindrical grinder is configured for small precision components — gauge pins, small spindles, instrument shafts and medical or optical device parts — where sub-micron repeatability across a varied, often small-batch job mix matters more than raw throughput.

Core Capability

Fine CNC infeed resolution and a stable, vibration-damped spindle let the machine hold tight tolerance on small-diameter parts while still being reprogrammed quickly between different precision job orders, which suits precision job shops that rarely run the same part for long.

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.

This precision tier is sized for small parts and job variety rather than long, heavy shafts — for larger diameters or lengths, our standard CNC cylindrical grinder line is the better starting point.

Workpiece Range

Covers gauge pins, small precision spindles, instrument and optical device shafts, and similar critical-tolerance small parts from Ø3–150mm and up to 600mm long, in hardened tool steel, stainless steel and precision alloys. Batch sizes are typically small to medium rather than continuous high-volume runs.

Job-to-Job Flexibility

Programs are stored per part number so a precision job shop can switch between different small-part orders without re-deriving grinding parameters each time, while still holding IT4–IT5 tolerance and roundness ≤0.001mm on each order.

Core Functions

  • Fine CNC infeed resolution (0.5µm/step) for controlled finishing passes
  • Vibration-damped spindle support for stable finishing on small, light workpieces
  • Automatic fine-dressing cycle to maintain wheel sharpness at low stock removal
  • Stored program library for fast changeover between varied small-part orders
  • Optional in-process gauge for critical-tolerance dimension verification
  • Optional superfinish/polishing attachment for sub-Ra0.1µm requirements

Quality Control

  • Roundness and surface finish verified with precision measuring equipment
  • Trial grind on the customer's sample part to confirm tolerance before quotation is finalized
  • Thermal and vibration stability check on the spindle and bed
  • Certificate of conformity issued for each precision-tier machine
  • ISO9001-certified process with documented warranty and calibration support

FAQ

  • Q: How is this different from a standard CNC cylindrical grinder?
  • A: This precision series uses finer infeed resolution and a more vibration-damped spindle specifically for small, light precision parts, whereas the standard range is sized for general shafts and rollers with larger diameter and length capacity.
  • Q: What tolerance can I expect on small precision parts?
  • A: Typical results are roundness ≤0.001mm and surface finish around Ra0.1µm, verified with a trial grind on your sample part before final quotation.
  • Q: Can it handle a mix of different small parts, not just one repeat job?
  • A: Yes, stored programs per part number make it practical to switch between varied small-batch orders without re-deriving grinding parameters each time.
  • Q: Is a cleanroom-compatible version available?
  • A: Yes, an enclosure option suited to sensitive precision or medical device work can be added on request.
  • Q: What is the typical lead time for this precision series?
  • A: Standard configurations usually ship in 60–80 days; cleanroom or custom gauge options may extend this to 90–110 days.

Equipment Configuration

  • Precision spindle bearings selected for small-diameter, low-mass workpieces
  • Precision linear encoders for fine axis feedback
  • Compact, rigid bed construction to limit thermal and vibration drift
  • Choice of Fanuc or Siemens CNC control for the precision series
  • Temperature-stable coolant option for tight-tolerance job runs
