Special-Purpose Machine Tools

Large turning wheel machine Valve finisher Crankshaft processing machine

Special purpose machines are designed to perform specific machining tasks for specific work pieces or machining processes which can not be carried out using conventional machines. Furthermore, they can be also designed to respond to customer’s factory capability or targetted work pieces. By installing required functions or equipment, special-purpose machine tools are capable for mass production in high productivity.

Special-Purpose Machine Tools



The transferline serves its mission of quickly responding to the change of automobile and motercycle markets. It is capable for mass production of engine・transmission component parts in high accuracy and productivity.

SAKURAI team of highly qualified Proposal Experts provide industry-leading machining line proposals. Continuous line operation is tested and machining accuracy and cycle time are confirmed with customer before delivery, therefore, production can be started immediately after delivery. To suit customers’ needs, SAKURAI sets up production lines by using various equipment from requested manufacturers.

Modular system

This is a new system that can standardize the bed, feed unit, control box and coolant tank of such a special- purpose machine as boring machine and multi-spindle head, including a machining center (MC). The system is so designed that you can use the standard portions of an already constructed processing line intact and renovate the line by changing only special processing portions. This enables you to shorten the design time to a great ex- tent and realize a large reduction of the total cost incurred by the line change.
