internal cylindricalsurfacetool

Overview
The Multi-Grind combines external and internal cylindrical grinding, surface grinding and tool grinding in a single industrial machine. It supports one-sided clamping or between-centers support, accepts an internal grinding unit on the headstock and performs light surface grinding and tool sharpening for cutters, reamers and turning tools.

Product details
The Multi-Grind is designed for flexible shop-floor use where combined operations reduce setups. Key functional features include a three-point bearing on the grinding spindle to reduce thermal effects, hydraulic longitudinal table feed with automatic direction change, the possibility to mount two grinding wheels simultaneously, central lubrication and a rigid cast-iron bed to minimise vibrations.

• Three-point spindle bearing for thermal stability and consistent surface finish
• Hydraulic longitudinal feed with automatic reversal and manual hydraulic-assisted feed
• Grinding headstock with transverse/vertical travel and rotation for multi-angle setups
• Accessible electrical cabinet and extensive accessory options (coolant, extraction, chucks, internal grinding unit)
