New Engineering, New Machines – Blades Sharper and Faster than ever.

The MVM PX1000

Introducing the newest member of the Renlaw team

Renlaw is proud to be adding to our prestigious collection of high-end blade manufacturing and re-sharpening machinery with one of the most sought-after professional blade sharpening machines.

This elegant specimen of expert engineering will support Renlaw’s existing blade resharpening services. The MVM PX1000 make us even more capable in assisting our clients than ever. The MVM PX1000 means a faster turn around time than ever on resharpening. Expect the same top quality results our customers have come to expect from Renlaw.

Why does resharpening mean so much to us? It’s simple – resharpening fits in with our commitment to providing sustainable, high quality products to our customers. Other blade manufacturers may sell cheap, disposable blades that need to be replaced frequently. Renlaw believes in providing products that last, blades that stay sharp, and service which allows you to keep using those blades for that much longer.

Call us old fashioned – but Renlaw upholds the belief that quality and excellent workmanship are more important than quick fixes.

We stand against the disposable culture. Our way of doing things is motivated by two of our most important core beliefs: Quality products are our pride; and sustainable practices ensure a better future for generations to come.

Currently, our resharpening services are utilized predominantly by our Cape Town based clients, but we are working towards growing this service further afield. After all,Renlaw is Africa’s leading blade manufacturer.

More about Renlaw’s new MVM PX1000 machine 

Things the Renlaw Engineers are geeking out about right now…

This beautiful MVM PX1000 has a useful grinding length of mm 1000 and has a magnetic chuck mm 117 wide and rotating from 0° to 90°. The grinding wheel motor is 3 HP, it has a reduction gear for the carriage feed 0,15 HP with fixed speed, adjustable carriage run by means of two adjustable mechanical stops, automatic wheel downfeed controlled by a potentiometer, head inclination +/- 3°. 

The basement is built in electro-welded steel and it undergoes a stress relieving treatment at a temperature of 650° in order to eliminate any stress, as well as to guarantee stability in time and precision. 

The sliding guides of the carriage are all one piece, and after undergoing planning and grinding procedures, both upper and lateral, they are covered by high precision tempered and rectified steel strips. 

The rotating chuck has two mechanical stops at 0° and 90° and is supplied with two stepped knife holders for the sharpening of four planer knives at once and with four clamping devices. On the operator side, two adjustable mechanical stops allow the choice of the carriage run length. 

The carriage is made in solid metal carpentry. 

It slides over four adjustable bearings with high precision. A reduction gear put in motion by a three-phase motor positioned on the basement moves the carriage by means of a trapezoidal belt. 

The grinding head is solid and compact and has a two poles motor, an electronic wheel down-feed, a ceramic cup wheel and can be tilted. 

The electric & electronic equipment is built in accordance to European safety Norms and it differs according to the options requested. A particular technique in the preparation of the surfaces, and the use of paints having a high chemical and mechanical resistance allow the machine to be highly resistant to the corrosive effects of the coolant over time. 

Grinding wheel downfeed and spark out cycle can be programmed on this model. 

Over the grinding head, the machine has a vernier by means of which the total material to be removed can be programmed: once this amount has been removed, the grinding wheel downfeed stops and the spark out working cycle begins. 

Digital programmer main functions: 

  • grinding wheel
  • motor start
  • water pump and magnetic cleaner start 
  • Carriage travel start 
  • magnetic chuck on 

It can also set following parameters: grinding wheel partial downfeed, sparkout time, carriage speed, grinding wheel downfeed at right side or right/left sides, and grinding wheel downfeed delay time. Once the machine has completed every working cycles, it stops automatically.
