Universal Bed type milling and boring machine 
The SEYMOUR B-Type is designed and manufactured in Halifax, England. The B-Type is a truly universal milling and boring machine. The machine is suited to both large and small jobs. The large bed is very versatile, allowing work on one large component or multiple smaller ones. Large overhanging components can be easily accommodated by attaching angle plates to the front of the bed.
The B-Type has been designed to be an extremely versatile machine to meet users requirements as efficiently as possible.
The efficiency is at the core of the B-Type designed, the standardization on the Siemens 828Dsl coupled with the latest highly efficient Sinamics motors and combi drive allows for a very compact design and high optimization of the servo and CNC equipment. The combination the highly efficient mechanical drive, Efficient Siemens motor and developing the Power at a low speed achieves exceptional metal removal using much less power than is traditionally expected. The Siemens 828Dsl runs Siemens Operate with Shopmill meaning that the end user programming and operation of the machine is identical to the 840D. The 828Dsl is the obvious choice for worldwide support allowing quick service and spares delivery if required in the future.
The B-Type is a very versatile machine designed to be at home in many sectors. This bed type moving column milling and boring machine configuration has proved a favourite with machine shops world wide and is generally thought of as the de facto large milling and boring machine. The B-type and HD30 milling head has been proved on many materials and will be equally at home machining;
- General purpose jobbing shop work.
- Fabrication and construction.
- Hard material milling machine for the likes of rail and hard steel alloys such as inconel.
The B-Type is designed in a modular manner to allow different options to be easily specified. The basic machine is aimed at customers who just want to cut metal and need nothing more than a well designed, robust, CNC controlled, easy to use milling & boring machine. Customers can request any option that might be required, be they purely technological or relating to the machine structure and modules used. A typical list options would be;
- Part probe
- Tool measuring probe
- Rotary tables
- Dividing Heads
- Angle plates
- Tool changer
- Spindle power
- Right angle head
- Automatic universal head (1/1 degree or 3/3 degree)
- Axis travels
- CNC system
- Bespoke coolant systems
- Perimeter guarding systems
- Bespoke CADCAM system
- .............And any other requirements
The B-Type is part of the Seymour 
range of machines. These machines are designed with efficiency in mind making the B-Type a good investment for your companies future.
At SEYMOUR we believe in keeping design and technical expertise in house, this gives us the greatest flexibility allowing bespoke design issues to be incorporated into the machines. Examples of this are the ability to provide a special purpose head or adding specific technologies.
The use of the very latest technology allows the machine to not only meet current safety standards but to also reduce the energy requirements and the environmental impact of the machine.
The design philosophy was to reduce the number of components, allow maximum access for maintenance, maximize efficiency and allow the maximum flexibility of the specification.
The B-Type can be supplied to various specifications, typical specifications would be;

Machining on rotated planes made easy
The Siemens inbuilt support for the universal head make machining on angled planes very easy. We configure the machine to do the hard work for you. Tell the machine the angle to machine at and it calculates the angles for the head joints and sets the working plane, no need for look up tables or trig. The operator can then easily programme the machine in the working plane and jog the machine relative to either the working plane or the default machine plane.

| Face milling 5mm depth, High speed traverse. The B-Type allows cutter and tip optimization for the most efficient cutting, reducing power usage, prolonging tip life and reducing Floor to Floor times | Face milling 5mm depth | Raw casting Face milling |
Slots and interpolated pockets
Interpolation of slots and pockets easily achieved. Conventional slot mills or end mills and modern tipped high speed cutters are intuitively dealt with and easily interchanged when tooling data is entered in the tool table.
