Precision Profile Grinding (PG) Services

Subcontratista de precisión fiable para talleres de herramientas

Precision Profile Grinding (PG) – Waida High-Precision SolutionsProfile Grinding (PG) delivers high-precision contour and profile machining where part function depends on shape accuracy rather than size alone. Our Waida PG machines enable repeatable precision, minimal deformation, and superior surface quality.

Process Overview

Rectificado de perfiles is a form-based grinding process:
Wheel Dressing: Diamond dressing creates a negative replica of the target contour.
CNC-Controlled Grinding: Wheel follows precise trajectories with micron-level feed control.
Profile Compensation: Optical and CNC systems allow real-time alignment and correction.
Outcome: Single-pass contour precision without multi-step accumulation errors.

Technical Capabilities

Parameter	Typical Values / Notes
Dimensional accuracy	±0.001 mm
Surface roughness (Ra)	0.1 – 0.2 μm typical
Repeatability	±0.002 mm
Minimum feature size	0.1 mm edge/slot
Maximum part size	Up to 400 mm × 200 mm × 150 mm (depends on machine model)
Max material hardness	HRC 68 (tungsten carbide, tool steel)

Key point: PG excels at small, delicate, or thin-walled parts without deformation.

Compatible Materials

Tungsten carbide & hard alloys
High-speed steel (HSS)
Tool steels (SKD11, DC53)
Stainless steels (SUS series)
Copper alloys & beryllium-copper
Heat-treated components

Engineering note: PG can handle post-heat-treated mold components and high-hardness inserts with micron-level contour control.

Typical Applications – Data-Driven

Application	Part Examples	Key Feature
Mold & Tool Components	Punches, die inserts, cores, sliders	R-angles, edges, profile critical
Precision Cutting Tools	Forming cutters, R-angle cutters, chamfer tools	Contour accuracy ±0.001 mm
Mechanical Motion Components	Cam profiles, followers	Profile defines motion accuracy
Electronics & Connectors	Terminals, contact springs	Small features, high repeatability
Gauges & Fixtures	Profile gauges, reference blocks	Dimensional consistency, low deformation
Medical / Precision Instruments	Surgical instruments, micro-cutting edges	Edge precision, complex profiles

Engineering insight: For parts where profile = function, PG ensures functional integrity.

Advantages vs Other Methods

Feature	PG	CNC / EDM
Contour precision	±0.001 mm	±0.01 mm typical
Surface finish	Ra 0.1–0.2 μm	Ra 0.4–0.8 μm
Edge consistency	High	Moderate
Material flexibility	Hard steels, carbides	Hard steels, limited carbides
Multi-step accumulation	Minimal	Higher, requires secondary finishing

When to Consider PG Outsourcing

Critical curves, edges, or profiles
Small, thin, or delicate parts
Parts requiring high functional repeatability
Low-volume, high-precision, or custom shapes

Decision rule: If your part’s performance depends on the contour, PG is often the only practical solution.
