NEW 2012 OSP-P300S CONTROL

A better way of doing things!

"The Okuma P300S Controller is dedicated to the Multus multifunction group of Okuma machines.  They incorporate class leading motors (PREX), encoders and scale feedback systems that are all Okuma manufactured technologies.

Our Thermo Friendly Concept system is SO accurate in it's operation and execution (every Okuma model has its own thermo thumbprint) that to achieve the same thermal deformation reduction and on-going control would require temperature control equipment using around 135,00kW/h per annum.  In broad terms, the CO₂ emission avoided is something like the CO₂ consumption capacity of 7,500 beech trees. The same applies for the required cooling system for the Hydraulic oils. 36,000kW/h saved and another 2,000 beech trees given a break.

As for PREX Motors, it's a straight out benefit - 5% increased energy efficiency, 10% power consumption decrease.  These results come from both the unique design of the motor itself and the simplified low energy drive system used."

Okuma Corporation has always been the manufacturer of both machine and control.  The OSP (Okuma Sampling Path) system was first developed with absolute position feedback encoder in 1963.  Okuma became Japan's only comprehensive manufacturer of both Machine & Control and by 1975 were well advanced to take advantage of the avalanche of NC and CNC machine sales that occurred all over the world.

Each OSP model released has an exceptionally long hardware design life.  In fact, and unlike other controller makers, Okuma has released only 5 major variants: OSP2000/2200/3000; 500/5000/5020; 700/7000; U/E10/100; P100/200 and now P300. We service them all.

This is one of the principal reasons why Okuma customers can keep their machines in operation all over the globe for so long and gain great financial benefit and productive advantage.

But as machine tools develop and progress in style, operation, flexibility, power and performance in response to the customer's requirements, so too must the CNC controller.

We take for granted these days that many machines have X (maybe 2), Y (maybe 2), Z (maybe 2), C (maybe 2), B and W axes. So it's not uncommon to have to control 10 axes or so of movement from the one controller.

The development of the OSP P-300S control is specifically aimed at delivering the power to drive multi axes, high performance multifunction machines like the Multus II series, for example.

The OSP P300S has an ease of operation that has arrived after researching just how machinists actually want to drive their multifunction machines.  We identified that they wanted to own a smoother and more effective way of producing parts and in so doing, banking savings in time both financially and personally.

In fact, the P300S delivers a reduction in preparatory programming compared to previous controllers. Time taken for tool registration, setting tool offsets, soft jaw machining and setting zero offsets is slashed by 47% from 360 keystrokes to 190 keystrokes.

Our research also uncovered that operators prefer the positive movement and the fast, safe and assured response of rotary switches for controls such as rapid traverse rate, feed rate override and spindle speed override.

Information from popup windows allows simple touch selection rather than typing the complete selected command.

In addition, Okuma's new P300S CNC multifunction controller has 2GB program storage.

The added processing power of P300S accommodates newly available and pre-existing standard features such as Collision Avoidance System (CAS), Machining Navi L (turning), Machining Navi M (Machining), Thermo Friendly adjustments, Variable spindle speed control for threading chatter elimination and continuous improvements to Super NURBS (high accuracy shapes at speed) – all with plenty of power to spare.

It is expected that the P300S will be joined by a gradual rollout of P300L and P300M, to support the more conventional CNC Lathes and Machining Centres respectively, over the coming 12 months.
