High Precision Grinding Machine

-- Steady & Reliable Manufacturer --

Intro

High precision means different things to different buyers, so this page sets out what each precision grade needs from the machine, the workshop and the measuring equipment, and points to the machine in our range that fits each one.

Core Capability

Machine accuracy is only one factor. Part rigidity, material stability, coolant temperature, floor vibration and the gauge used to check the result all limit what can be held in production, and we state those conditions alongside every roundness figure.

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.

Precision Grade Guide

GradeTypical RoundnessTypical ToleranceRecommended MachineWorkshop Conditions
General precision≤0.005mmIT6–IT7CNC Cylindrical Grinder / External GrinderNormal workshop
High precision≤0.002mmIT5CNC Cylindrical Grinding Machine for Shafts or Automotive PartsStable workshop, coolant temperature control advised
Ultra precision≤0.001–0.0015mmIT4–IT5Precision Cylindrical Grinding Machine or OD Grinding MachineTemperature-controlled room (about ±1–2°C), isolated foundation

Roundness figures are for a rigid part and a measuring system that is at least ten times finer than the tolerance. Share your drawing and inspection method and we will tell you which grade you actually need.

Choosing the Right Grade

Buying an ultra-precision machine for IT7 parts adds cost without improving the result, and installing one in an uncontrolled shop can fail to deliver its rated accuracy. Matching grade to tolerance and environment usually gives a better return than specifying the tightest machine available.

What Limits Precision in Production

Typical limits are blank straightness, residual stress in hardened parts, workshop temperature drift over a shift, coolant temperature and the measuring method. We include thermal compensation and coolant temperature control on the higher grades to reduce the first three.

Core Functions Across the Precision Range

  • Fine infeed resolution down to 0.5µm on the higher precision grades
  • Thermal compensation to limit drift over a shift
  • In-process gauging with closed-loop size correction
  • Fine dressing cycle for stable finish at low stock removal
  • Coolant temperature control on high and ultra-precision grades

Quality Control

  • Geometric accuracy verified with laser and precision measuring equipment
  • Thermal stability tested over a shift-length cycle on high grades
  • Trial grind on the customer's part with the inspection method agreed beforehand
  • Certificate of conformity with calibration traceability on precision-grade machines
  • ISO9001-certified manufacturing with documented warranty terms

FAQ

  • Q: How do I know which precision grade I need?
  • A: Start from your tightest drawing tolerance and how it will be measured, then choose the grade whose typical roundness is comfortably inside it; send the drawing and we will advise.
  • Q: Can an ultra-precision machine hold its accuracy in an ordinary workshop?
  • A: It will perform better than a general machine but may not reach its rated figures without temperature control and an isolated foundation, so we state the workshop requirements up front.
  • Q: Why does measurement matter so much?
  • A: A gauge that is only as accurate as the tolerance cannot confirm the result; a rule of thumb is a measuring system ten times finer than the tolerance being checked.
  • Q: Can you prove accuracy before we order?
  • A: Yes, we can grind your sample part and report results with the inspection method agreed with you in advance.
  • Q: What is the typical lead time?
  • A: General and high-precision machines typically ship in 60–90 days, ultra-precision models in 90–130 days.
