computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
Teknics ZeroClamp USA introduces its Zerolox XP 80Z Zero Point Workholding Automation Console made in Germany. The Zerolox Console provides a universal interface that allows quick precision positioning in seconds for clamping 5 axis self-centering vises, pallets and work pieces on 3, 4 and 5 axis CNC machines. It’s non- wearing technology ensures high reliability. The pneumatic console comes ready to be used either manually or with cobot/robot automation.
The ZeroClamp Zerolox Zero Point Automation console is the only Zero Point product like it on the market today. It is superior both in repeatability and clamping force to single Zero Point workholding units having only 1 clamping stud with an orientation pin or slot. In addition to manual mechanical plate Zero Point clamping systems using 4 V-notched studs on a 52/96 mm spacing which requires clearance in multiple geometric planes.
ZeroClamp’s patented Zero Point center cone technology offers the highest rigidity and accuracy of 2.5um (0.0001”) repeatability. Thermal growth is always at the center point of the console important for accurate 5 axis machining and maintaining the center of the tool point and axis of rotation.
The 4 integrated 90 mm Zero Point clamping units provide high clamping forces of 50,000 N, 50 kN, 11,240 LBS., the highest clamping forces available in the industry with over 5.5 tons!
Its compact low profile design is only 40 mm high by 160 mm square (1.57” X 6.3” Sq.) and 90 degree indexing X 4 lets you rotate for your 2nd operation or sides 4 & 5.
The automation console can be used with ZeroClamp’s 5 axis self-centering automation ZeroVise M 80/120A, up to 203mm/ 8” Sq. pallets, fixtures, direct part clamping, dovetail fixtures and 52/96mm mounting pattern on compatible 5 axis vises with adapter plate.
Pneumatically actuated with 90 PSI required only to unlock the console. Pneumatic porting for automation on the back of the console or by a robot or manual operation with an air gun into the 2 side ports for open, close and air pressure differential sensing of clamped confirmation comes as standard.
No rotary unions or airlines are required that can get tangled up on 5 axis CNC’s, operates without a constant air supply. The compact design can be mounted to your 5 axis CNC with or without a riser, 4 and 5 axis rotary tables, tombstones, trunnions and all automation systems. Ideal for automation with cobot/robot and as a machine table automation interface.
The complimentary ZeroClamp manually actuated 5 axis self –centering ZeroVise’s M80/120A are available in 80mm or 120 mm wide sizes and comes with 4 integrated size 90 Zero Point clamping studs. The vises can be exchanged manually in seconds with the ZeroLox and for automation comes ready to accommodate a simple non-pneumatic robot gripper. The vises are completely sealed self-cleaning, chip repelling design eliminating cutting chips and coolant from collecting and entering inside. This provides a low cleaning effort when exchanging parts and eliminates coolant dripping out of the vises while they are out of the machine. They are compact, low weight ideal for cobots/robots and one size for all clamping ranges up to 8.2”wide parts. By reversing the jaws and changing the 2 quick change jaw positions the vise length does not increase. This allows the use of short tooling providing higher feed rates, superior surface finishes and optimal part access. Available with many quick change interchangeable jaw options.
