CNC Rockwell Hardness Testing Machine
HR-620B
• Electrically powered Y-axis table equipped as standard. (Can be expanded with an electrically powered X-axis table)
• Perform automatic Rockwell multi-point testing of multiple parts or workpieces.
• It is also possible to incorporate a fully automatic Rockwell hardness test system where even workpiece transport is automatic.
(Linking with PLC requires the FORMEio software (sold separately).)
Test force: 9.807 - 2,452 N (1 - 250 kgf)
Maximum load: 100 kg
