Small Metal Surface Grinding Machine
A grinding machine utilizes high-speed rotating grinding tools (such as grinding wheels, oil stones, abrasive belts, etc.) to process workpiece surfaces through grinding. Its core principle involves the relative motion between the grinding wheel and the workpiece to remove material from the surface, achieving high-dimensional accuracy, low surface roughness, and specific shape requirements. During the grinding process, the abrasive grains on the grinding wheel remove material through micro-cutting, extrusion, and friction, while coolant is used for heat dissipation and chip removal.
- Product Introduction
一. Core Features
High-Precision Machining: Achieves IT5-grade precision (tolerance ±0.001mm) and surface roughness as low as Ra 0.01μm, making it suitable for manufacturing precision parts.
Wide Material Adaptability: Capable of machining high-hardness materials such as hardened steel (HRC60 and above), cemented carbide, ceramics, and glass, as well as soft metals like copper and aluminum.
Excellent Surface Quality: The grinding process leaves no tensile stress on the workpiece surface, ensuring high fatigue resistance, which is ideal for high-load components such as bearings and gears.
Broad Machining Range: Covers internal and external cylindrical surfaces, conical surfaces, flat surfaces, threads, gear tooth profiles, and complex curved surfaces.
二.Main Types and Applications
1.Cylindrical Grinding Machine
Application: For grinding external cylindrical surfaces, conical surfaces, and end faces of shaft and sleeve components.
Typical Model: The M1432A universal cylindrical grinder can grind cylindrical workpieces to IT6~IT7 accuracy grades.
2.Internal Grinding Machine
Application: For grinding internal cylindrical surfaces and end faces, such as bearing inner ring holes and gear holes.
Feature: The grinding wheel spindle features very high rotational speed (10,000~20,000 rpm) to compensate for the lower linear speed of small-diameter grinding wheels.
3.Surface Grinding Machine
Application: For grinding flat surfaces like machine tool guideways and mold surfaces.
Classification:
Horizontal-Spindle Grinder with Rectangular Table: Suitable for batch processing of small flat surfaces.
Vertical-Spindle Grinder with Rotary Table: Suitable for continuous processing of large flat surfaces.
4.Centerless Grinding Machine
Application: High-volume grinding of cylindrical parts (e.g., bearing rollers, pins).
Principle: The workpiece is rotated by a regulating wheel and ground by the grinding wheel, without the need for centers or chucks for positioning.
5.Tool Grinding Machine
Application: For sharpening cutting tools (e.g., lathe tools, milling cutters, drills) and machining mold components.
Feature: Equipped with a high-rigidity bed structure and precision ball screws; the grinding wheel spindle speed can reach up to 4100 rpm.
6.Specialized Grinding Machine
Types: Gear grinding machines, thread grinding machines, crankshaft grinding machines, camshaft grinding machines, etc.
Application: Used for manufacturing high-precision components in the automotive and aerospace industries.
