Line boring jig
Providing unprecedented added value by converting the line boring process to a general-purpose machine process!
Total design of jigs and tools
Flexible response to customer requirements
Reduced number of equipments by machining on general-purpose machines
Support for multiple processes by switching jig movements
Amazing facts!
── Introducing ideas and technologies ──
Line boring jigs realise general-purpose machine machining through the total design of tools and jigs.
In addition to general-purpose machines, the line boring jig also provides a lot of added value, such as process intensification by switching jig movements, multiple hole machining and reduced changeover man-hours due to the upper jig / lower jig structure.
Structure
Total design of fixtures and tools enabling general-purpose machines
Excellent!
By mounting the support phase setting mechanism on the jig side and placing the drive key for the support on the line bar, no more insertion guide section needed (which was necessary for line bars on special-purpose machines), thereby reducing the overall length of the line bar. The total design of the jig and tooling enables ATC and realises machining on general-purpose machines.
This is the point!
Support for multiple processes by switching jig movements
Excellent!
Process integration of crank and cam hole machining is achieved by switching the operation of the support pin.
This is the point!
For machining multiple holes
Excellent!
The advantages of general-purpose machine machining are utilised for line boring of crank and cam holes, as well as for the machining of multiple holes where positional accuracy is required. We can handle any hole to meet your needs.
This is the point!
Reduction of changeover man-hours
Good!
Upper and lower jig structure enables different workpieces to be used by simply changing the upper jig.
Change of stage is possible by simply replacing the bolts.
Development / product concept
“Current status and challenges”
- Traditionally, the line boring process for crank holes required machining with special-purpose machines.
- However, the introduction of specialised machines requires high capital investment and has low versatility, so machining using general-purpose machines was required.
“Development points”
- The ‘Line boring jig’ realises machining on a general-purpose machine through the total design of the jig and tools.
- The switching lot is operated only by spindle movement, enabling automatic switching within the machine.
- It also offers the added value of multiple hole machining.
