Tombstones

Product catalog summary

Overview: This document serves as a comprehensive guide on tombstones used in manufacturing, focusing on three designs: double angle, triangular, and octagonal. These are compatible with 400 or 500 series pallets and utilize GRESSEL clamping technology.

Advantages: The tombstones provide optimal spindle accessibility with minimal interference. They feature a sturdy hollow body for high rigidity and vibration absorption, fine-milled clamping surfaces for precise positioning, and a bore hole grid with hardened sleeves and galvanized steel tapped bushes.

Specifications: There are 18 standard versions with short delivery times, available in three forms with blank clamping surfaces and a 50 mm continuous bore hole grid. They are compatible with GRESSEL clamping devices and available in pallet sizes of 400 mm and 500 mm.

System Overview: Configuration examples show machine spindle accessibility across all tombstone forms. A construction kit section details configurations like double angle with bore hole grid, triangular, and octagonal tombstones with reduced grids.

Applications: The document outlines applications using different clamping systems such as gripos, duogrip, and multigrip, allowing flexible clamping of multiple workpieces to enhance machining productivity.

Technical Details: Detailed specifications for each tombstone type include dimensions, weight, and order numbers, with diagrams and tables illustrating dimensions and configurations.

Specifications and Product Descriptions: Detailed specifications for vertical units and tombstones include duogrip and easygrip models, described by jaw width, clamping force, weight, and scope of delivery, including tools like torque wrenches and ring bolts.

Dimensions and Technical Details: Dimensions for each unit type are provided, detailing critical measurements for installation and operation, including bore hole grid layout for simultaneous positioning and attachment.

Clamping Systems: Two quick change palleting systems are described: GRESSEL gredoc and SCHUNK VERO-S, offering quick, non-tilting, precision positioning with specific height tolerances and repeat accuracy, designed for multi-side machining and single pallet clamping.

Form and Position Tolerances: Fundamental form and position tolerances are outlined for all machined tombstone options, with clamping surfaces fine-milled to a roughness average of Ra 1.6.

Assembly Instructions: Instructions for assembling GRESSEL clamping devices on tombstones are provided, emphasizing the use of fitting screws for direct positioning and attachment.

Checklist for Proposal Management: A checklist assists in proposal management, requesting machine data like type, model, and pallet size for a complete quotation.

Contact Information: The document concludes with contact details for GRESSEL AG, including address, phone numbers, and email for inquiries.
