GOST 30512-97 PDF

Full title and description

GOST 30512-97 — "Roll grinding machines. Standards of accuracy" (ГОСТ 30512-97). The standard establishes accuracy norms, geometric and measurement requirements for roll (cylindrical) grinding machines used to process outer cylindrical, conical and profiled surfaces of rolls, including machines with various degrees of automation and CNC.

Abstract

This interstate (GOST) standard specifies accuracy classes, permissible deviations and measurement methods for roll grinding machines with horizontal spindle axes, including requirements for machines with fixed or movable carriages and heads used for longitudinal and plunge grinding of rolls mounted in centers and/or steadies. It defines machine limits (maximum workpiece diameter, length and mass) and normative references for verifying geometric accuracy.

Scope

Applies to roll-grinding machines of various degrees of automation (including CNC) with horizontal spindle axis, for longitudinal and/or plunge grinding of external cylindrical, conical and profiled surfaces of rolls fixed in centres and/or steadies. The standard covers machines with maximum grindable roll diameter up to 2600 mm, maximum installed roll length up to 12 000 mm and maximum roll mass up to 280 000 kg, and assigns accuracy classes П, В and A. It does not apply to specialized or special-purpose roll grinders or to roll grinders based on heavy cylindrical grinders where geometric accuracy is determined according to GOST 11654. Intended for new equipment designs.

Key topics and requirements

• Definition of accuracy classes for roll grinding machines (classes П, В, А) and associated permissible deviations.
• Geometric accuracy requirements (straightness, cylindricity, concentricity and runout) and their measurement schemes.
• Maximum machine/workpiece parameters (diameter, length, mass) that the standard addresses.
• Measurement and inspection methods referenced to other GOSTs (measurement schemes, test pieces, axis designation for CNC machines).
• Exclusions and special-case handling (specialized machines and machines based on heavy cylindrical grinders — see GOST 11654).

Typical use and users

Manufacturers and designers of roll grinding machines, machine-tool builders, quality and inspection laboratories, production engineering departments in steel, paper, rubber and other industries that use or refurbish rolls, and national/regional standards bodies. The standard is used to specify machine acceptance criteria, to prepare test procedures for accuracy verification, and to guide selection of machines to meet production tolerances.

Q: What does it cover?

A: It covers accuracy classes, permissible geometric deviations, measurement schemes and limits for roll grinding machines (horizontal spindle), including typical maximum roll diameter, length and mass, and excludes specialized or special-purpose roll grinders.

Q: Who typically uses it?

A: Machine-tool manufacturers, equipment purchasers in heavy industries (steel, paper, rubber, etc.), inspection and metrology laboratories, and standards/technical departments responsible for machine acceptance and maintenance.

Q: Is it current or superseded?

A: The document GOST 30512-97 is listed as the 1997 interstate standard and was introduced into force on 1 January 2002; commercial catalogs and standards databases list it as active.
