Thanks for all your advice so far.

The link that Jaydee posted has comprehensive spec. for a newer variant of the machine (I think it's probably very similar). The machine I'm using is pictured there but doesn't seem to have spec.

EDIT: I've found the exact spec for the machine I'm using (PNC-2300A) and as far as I can tell they are identicle.

"Specifications:

Table size: 305 mm x 230 mm

Max cutting area: 305 mm (X) x 230 mm (Y) x 30 mm (Z)

Feed rate: X, Y-axis: Max. 3600 mm/min Z-axis: Max. 1800mm/min

Software resolution: 0.01mm/step or 0.025mm/step (XY axis only)

Mechanical resolution: X, Y and Z-axis: 0.00125mm/step (micro-step control)

Spindle motor: 30W (DC motor)

Revolution speed: 5000-15000 rpm

Tool chuck: Cutter holder and collet system

Interface: Parallel (in compliance with centronics specification) or Serial

Buffer size: 1MB

Instruction system: CAMM-GL I (mode1, mode2)

Source: 1.8 A / 117 V 0.9 A / 220-230 V 0.9 A / 230-240 V

Acoustics: During no-load operation: 60dBA or less Standby mode: 30dBA or less

Weight: 28.5kg (62.8 lb.)

Operation temperature: 5-40 deg C

Operation humidity: 35-80% (no condensation)"

There is no means for lubrication/coolant delivery inherent in the machine, would it be a good idea to intermittently spray some WD40 on the work peice (or some other lube/coolant)?

Of the 2 mm "slot drill" that I'm using the manual states: "Slot drill - These tools are excellent for making slots, cutting out, routing etc. They work well with most materials. They cut accurately and generally leave a good surface finish (depending on material, feeds, speeds and depth of cut). The fluted design ensures good waste removal. These tools are therefore suitable for deep cutting (subject to multiple passes). Being carbide tipped they should have a long service life if treated with care."

2nd EDIT: Just been looking up some links for the machine:
