Vertical Hydraulic Broaching Machine

The BRONZ is a heavy duty, microprocessor controlled production line machine. Its vertical construction utilises minimum floor space and fits more easily into the flow of work and hence this machine is preferred for use in mass production lines. The broaching tools are handled automatically in the cycle, and a variety of components with different hole shapes can be processed on the BRONZ series having capacity ranging from 10 to 25 tonnes. To cater to the needs of large batch production and mass production in production lines, these machines are equipped with features like: Alignment of broaching and hydraulic forces to ensure minimum friction and wear; Main pillar guideway for the puller carriage protected from dust and environment by housing inside the closed main frame; Wear plates fixed on the outer diameter of the main pull cylinders form the track for the rollers on the broach feeder carriage; Bronz bushes in the puller carriage are automatically lubricated during cycle from the hydraulic system, sealed from the outside and protected with wipers; 3 broaching stations with single, dual or triple attachments make possible multiple or different broaching operations simultaneously, for example rough and finish broaching of work-pieces; Automatic handling of broaches and positive locking of the broach end at the holder unit for safety in handling heavy broaches; Double-handed operation at switchboard console ensures operator safety; In addition to supply at the top, additional coolant spray on to the broach below each station to wash away chips and swarf; Special accessories ard custom built fixturing can be provided on option for automatic alignment of teeth for multi-pass broaching of splined bores; Overload indicator/controller with a pressure transducer sense the actual tractive force and indicate, and stop the machine automatically in case of overload; and Diagnostic software for ease of maintenance.
