Micrometer Setting Standards

For setting external micrometers, calipers etc. to zero, providing accurate repeatability of measurements. Flat, lapped measuring ends with fitted heat insulation block.
Manufactured to BS 870.

167 Series (Micrometer NOT included)

Oxford? Precision Wire Micrometer

Specially designed for measuring wire diameters 0-10mm. The front of the body is flat to help support the wire when measuring. With knurled thimble, ratchet stop and vernier scale barrier, all over satin chrome finish.

Knife Edge Vernier Calipers

Give 4 types of reading, internal, external, depth and step. Dual reading scale (metric and inch) with 14 bevelled vernier scale for reduced parallax reading error, fine adjustment assembly and knurled locking nut. Manufactured from hardened stainless steel for rigidity with satin finish. Conform to DIN 862. For quick accurate setting of all three axes (X, Y, Z) by analogue differential indicator. Suitable for all machine tools with CNC, NC, DRO and also for EDM/spark erosion tools. Universal - one tool measures length, height, diameter and centre. No calculations and no 'trial and error' involved. Increses production and efficiency, reduces job time and operator requirement. Pre-adjusted to a concentricity of 0.01mm maximum.
Indicator diameter: 50mm.
Clamping shank diameter: 20mm.

Oxford Precision? Vee Blocks

Are matched and numbered pairs of closed grained iron castings accurately machined. Precision 90 vee blocks. Supplied as a pair.

Portable Optical Refractometer

For determining the concentration of oil in water emulsions and transparent solutions, such as machine shop coolant.
Maintaining the correct mixture in coolant systems is vital to ensure optimum performance from cutting tools.
To protect the machine and workpiece from corrosion and
to reduce the risk of health hazards arising from incorrect
concentrations of water soluble oils.
To economise the use of water base cutting
fluids and grinding fluids.
