Increase Multi-Operation Productivity with the Portable 2op VMC

Note: This machine has been replaced by the TRAK VMC2 Vertical Machining Center featuring the ProtoTRAK RMX CNC.

Application Example 1

Before TRAK 2^op
— Total man hours: 20.6/lot

Parts are processed through a cell consisting of two turning centers that are run simultaneously by one operator. One turning center performs the 1^st operation while the other performs the 2^nd operation. Once the entire lot is processed through the cell, it is moved 30 feet to the machining center to complete the 3^rd operation by a second operator.

TRAK 2op Application Example 1, Figure 1

Simultaneous 1^st and 2^nd operations machining

And 30 feet away...

TRAK 2op Application Example 1, Figure 2

The 3^rd operation machining center is 30 feet way from 1^st and 2^nd operations.

After TRAK 2^op
— Total man hours: 12.5/lot

Parts are run through a cell consisting of two turning centers and the portable TRAK 2^op VMC. All three machines are run simultaneously by the same operator — one turning center performs the 1^st operation, the other turning center performs the 2^nd operation, and the TRAK 2^op performs the 3^rd operation.

TRAK 2op Application Example 1, Figure 3

Simultaneous 1^st, 2^nd, and 3^rd operations machining. Space matters when creating work cells, so the compact 30″ x 48″ footprint of the TRAK 2^op makes it the ideal addition for 2^nd or 3^rd operations.

Example 1 Results

	Before TRAK 2^op	After TRAK 2^op
Lot Size	150 pieces	150 pieces
1^st Operation Cycle Time (turn one side)	2.25 minutes	2.25 minutes
2^nd Operation Cycle Time (turn oposite side)	5 minutes	5 minutes
3^rd Operation Cycle Time (mill, center drill, drill)	3.25 minutes	4.25 minutes
Total Man Minutes	(5 + 3.25)*150 = 1,237 minutes or 20.6 hours	5*150 = 750 minutes or 12.5 hours

Application Example 2

Before TRAK 2^op
— Total man hours: 22.5/lot

Parts are machined “three up” on the machining center in operation sequence (operations 1, 2, and 3). The machine is run by one operator.

TRAK 2op Application Example 2, Figure 1

1^st, 2^nd and 3^rd operations machining

After TRAK 2^op
— Total man hours: 13.8/lot

Parts are machined “two up” on the machining center in operation sequence (operations 1 and 2). The portable TRAK 2^op is placed next to the machining center and simultaneously performs the 3^rd operation. One operator runs both machines.

TRAK 2op Application Example 2, Figure 2

3^rd operation machining simultaneous with 1^st and 2^nd operation machining. Parts are machined "two up" on the machining center and "one up" on the TRAK 2^op.

Example 2 Results

	Before TRAK 2^op	After TRAK 2^op
Lot Size	150 pieces	150 pieces
1^st, 2^nd and 3^rd Operation Cycle Time (face mill, center drill, drill, mill, tap)	9 minutes	n/a
1^st and 2^nd Operation Cycle Time (face mill, center drill, drill, tap)	n/a	5.5 minutes
3^rd Operation Cycle Time (mill, center drill, drill, tap)	n/a	4 minutes
Total Man Minutes	9 *150 = 1350 minutes or 22.5 hours	5.5*150 = 825 minutes or 13.8 hours

The TRAK 2^op was designed to increase the productivity of multi-operations machining. It can be moved easily and quickly to meet the needs of constantly changing job requirements, and can be deployed in nearly limitless work cell configurations.
