Five-axis machining centre shown for first time
A 5-axis machining centre of rigid portal type design and combining big capacity with a high level of structural robustness was shown at MACH 2006 alongside a universal bed-type miller
Ward Hi-Tech used MACH 2006 to confirm their position as one of the leading privately owned CNC machine tool distributors in the UK. With more than 60 models available from a portfolio of principal partners that include Doosan Mecatec of Korea, Dah Lih of Taiwan and CME of Spain the company showed a total of 10 CNC machines - including three new models.
Shown for the first time in Europe, the Dah Lih PT128 5-axis machining centre is of rigid portal type design combining big capacity with a high level of structural robustness.
CNC control is the Heidenhain TNC i530 Axis travels are X - 700mm, Y - 800mm, Z - 510mm, spindle speeds 15,000 rev/min, spindle taper BT40 and rapid traverse 30m/min in all axes.
The 40 ATC tool magazine is mounted separately from the machining area to prevent ingress of coolant and swarf and ensure the machine can be used to its full capacity.
The machine build incorporates a heavy duty trunion style 400mm diameter 5-axis table arrangement providing continuous 5-axis machining capability.
Unlike many 5 axis machining centres, at 14.000kg the PT128 is a true ‘heavyweight’ and is ideal for producing larger aerospace components that require true 5 axis capability.

Universal bed-type and travelling column CNC milling centres and high speed, 5-axis bridge-type machining centres, manufactured by CME, Spain, are now being marketed by Ward Hi-Tech
Vertical machining centre has swivelling head
A 5-axis vertical machining centre features a thermally stabilised head with motor spindle that swivels about the B-axis, while the fifth CNC axis is provided by a horizontal rotary table
Five-axis vertical machining centre is affordable
Offering simultaneous 5-axis machining at an affordable price, a vertical machining centre gives maximum versatility, as the trunnion table can be quickly, and easily, removed for 3-axis work
* vertical machining centre - from the well known Dah Lih family of vertical machining centres the MCV-720 demonstrated its versatility machining a stainless steel aerospace component utilising an integrated 4th axis rotary table.
The MCV-720 is one of the best selling vertical machining centres in the UK and features axis travels of X - 720mm, Y - 460mm, Z - 510mm, spindle speeds of up to 8000 rev/min, 15HP main drive, 24 tool auto changer and standard specification is complete with high pressure through spindle coolant, bed wash, chip conveyor and table setting probe to provide a tremendous value for money package.
A feature of all Dah Lih machining centres is the on board ‘Manual Guide’ CAP system built into the Fanuc control.
This provides the user with a conversational programming system with colour graphics that can be used alongside or instead of the standard ‘G’ code format and is ideal for difficult programming operations.
* CME universal head, bed-type milling machine - from CME an example of this manufacturer’s large range of universal bed type CNC milling machines was on display throughout MACH.
The CME FS2 is equipped with Heidenhain TNC i530 CNC system and has axis travels of X - 2000mm, Y - 1000mm and Z - 1000mm.
Main drive is by 30HP motor and speed range 50-4000 rev/min provides a robust machining capability particularly in steel.
The heavy duty square ram is fitted with CME’s own design universal milling head with ISO50 taper allowing full power to be transmitted to the cutting tool in any horizontal or vertical position.
CME build bed type and travelling column style universal milling machines with X travels up to 20m and with specifications that can include high speed spindles up to 40,000 rev/min.
