EFCO Grinding and Lapping Compound Overview
Turning
- Innovative and Versatile Turning Equipment
The EFCO product range comprises portable and stationary lathes and flange-facers, both CNC-controlled and conventional:
- EFCO Portable lathes for sealing faces, flanges and bores (TD)
The EFCO TDs are portable lathes for precision machining of bores and sealing surfaces in valves, cylinders, pumps, turbine housings, etc. These machines are suitable for use on site and in the workshop, in power stations, for valve servicing, for chemical and petrochemical facilities, in steel construction, in shipyards and in oilfields.
The TD sports a multitude of excellent properties and is therefore the most powerful, safest lathe of its kind on the market. The outstanding properties of the new TD include:
- Stable bore machining
- Continuously variable, automatic axial and radial feeds
- Handy control panel, fine adjustments at the gearbox casing (no intervention at the rotary head required)
- Use of square standard turning tool holder
- Maximum working depth can be extended

- EFCO Portable facing machines for flanges with ID-clamping (TDFI)
The pressure to reduce costs in industrial maintenance increases. So does the demand for durable and efficient machines. Due to its flat design and the low weight, the portable, ID-mounted TDFI is ideal for applications in areas with limited working space.
The EFCO TDFI machine is particularly suitable for machining:
- Flanges of any kind
- Fitting housings
- Container flanges
- Heat exchangers
- Shipbuilding fittings
- Columns in refineries and the chemical industry
- Smooth and spirally grooved flange sealing surfaces
The TDFI-3, 4 and 5 make use of a common driveunit. According to requirements, the neededsize of machine can be obtained by modification of the turning- and clamping arms.
- EFCO Portable CNC-Controlled Lathe (TD NC)
EFCO NC Series
The lathes in the NC series open up an almost infinite number of surface machining options. We achieve a completely new quality standard in flange and valve seat machining. Because of the pre-programmed processing cycles, the TD-2.02 NC special machine is ready for immediate use, and can be operated after just a small amount of instruction and no previous CNC programming knowledge. Machining options with the EFCO NC lathes. Of course, you can also supplement the program package with your own CNC programs.
TD-2.02 NC
In addition to grooving, hole machining is the other speciality of the TD-2.02 NC. The immersion depth of the machine can be increased beyond 600 mm using optionally available accessories.
The machines of the NC series are suitable for:
- Facing,
- Taper turning,
- Radius turning,
- Hole turning,
- Grooving (axial).
- EFCO Portable CNC-Controlled Flange Facer (TDF NC)
NC Series
The lathes in the NC series open up an almost infinite number of surface machining options. We achieve a completely new quality standard in flange and valve seat machining. Because of the pre-programmed processing cycles, the TDF NC special machine is ready for immediate use, and can be operated after just a small amount of instruction and no previous CNC programming knowledge. Machining options with the EFCO NC lathes. Of course, you can also supplement the program package with your own CNC programs.
TDF-2 NC
Like all lathes in the well-tried TD and TDF series, the TDF-2 NC is also designed for chip-removing facing and internal machining of rotationally
symmetrical components.The special strength of the TDF-2 NC is its robust design, which makes it particularly suitable for cutting and machining grooves.
The TDF-2 NC is fixed to the fl ange using an external clamping system, and the basic version has a large facing head, a main drive, a clamping
device and the Zaxis for vertical movements.
The machines of the NC series are suitable for:
- Facing,
- Taper turning,
- Radius turning,
- Hole turning,
- Grooving (axial).
-
- EFCO CNC-controlled vertical lathes (PDM)
PDM machines are designed for the axial machining and facing of fitting housings (gate valves, valves, check valves), pumps and similar rotationally symmetrical components. They have infinitely variable speed control and axial and radial feeds (Z and X axis) with infinitely variable control that make it possible to move both axes simultaneously at different speeds.
They are equipped with CNC programs that are specially tailored to turning requirements. During program development, special attention was paid to making operation as simple as possible. Operation takes place using a portable electronic control unit.

- EFCO Stationary precision turning machine (SPM)
Stationary precision turning machines, CNC-controlled. The optimum solution for complete machining of valves, for general overhaul and also for use in production. The machines of this range have precision inclined tables (±12°, accuracy ±10“) and have been optimised for more efficient machining of valves. A particular advantage for the machining of gate valve sealing faces is the clamping. It is possible to machine both sealing faces with only one clamping by adjusting the angle at the swivel table. The symmetry of both sealing faces is thus ensured. Due to the flexible design, SPM machines can also be used for other machining tasks.
